6 Summaries of Tunnel Work in 223

Summary of Tunnel Work in 223 1

I have been working in the company for almost a year. During my tenure, I am very grateful to the leaders of the company, especially General Manager Li, General Manager Han and colleagues for their support and help. I also quickly integrated into our collective and became a member of this big family. I am glad that I came to Shandong Federal Hengsheng, a warm department, with the care of leaders and the help of colleagues, and felt this collective atmosphere. I have learned a lot from coming to the company, and I have grown a lot. I am even more grateful to the leaders for their esteem and care. In the future, I will be strict with myself and do my job well.

all these have enhanced my awareness of coordinating my work. In the past year, I have tried my best to satisfy the company and the leaders. However, some mistakes have occurred in my work, which has also caused losses to the company. I apologize to the company and the leaders. I know that I have many shortcomings and deficiencies, and I am also improving myself little by little.

1. Monthly work schedule and sales statistics of sales managers in various provinces and regions:

This kind of report is quite handy for me. However, while filling in the data and contents, I have always insisted on being cautious. We all know that this report is a powerful basis for provincial sales managers to prove their business level to their leaders. Once the data and contents are wrong, it will bring negative effects to provincial sales managers and unnecessary troubles to the company. Therefore, it must be timely and accurate, so that the company leaders can make corresponding countermeasures according to this table for different regions, so as to control risks.

2. Summary of daily work in the office:

As the sales office of the national department, I know the importance of the post. The sales office is an important hub that connects the preceding with the following, needs communication, coordinates the left and right, and contacts all directions, etc., so as to provide a good guarantee for sales personnel. During more than a year, I have been in contact with all kinds of work in the sales office. These jobs also require a high level of patience and care. Prepare the delivery materials (color pages, samples, etc.), provide the documents required by customers, sort out the sales forms, and so on. In the face of these various daily affairs, we should have a beginning and a end, arrange and follow up (for example, follow up the express delivery in time, check the website if you have time, and ask customers if the goods have been received).

I can also enhance my personal communication skills while working. Sales office is a connecting link between the preceding and the following, communicating inside and outside, coordinating the left and right, grasping the latest changes in the market, and doing all the rear protection for business managers. We should also enhance our awareness of self-coordination when dealing with the tedious daily affairs such as the first camp materials, agency agreements, publicity color pages, samples and so on. After a year of hard work, I have basically achieved everything, and everything has an echo. And learned to make a work plan. Orderly and effective

Third, the direction of future efforts:

Over the past year, we have made progress in the spirit of loving our posts and being dedicated to our work, but there are still some problems and shortcomings. If the goods are not tracked in time during the delivery process, the goods will arrive in the hands of customers late. The tracking work is not perfect enough; In the future, I will learn a lesson and work hard in the following three directions:

First, I will strengthen my own study, expand my knowledge, study medical professional knowledge hard, and be aware of the development and overall planning of the same industry;

Second, we should seek truth from facts in all aspects, and be good assistants to leaders.

Third, we should be attentive, careful, patient and open-minded.

in the future work, I will foster strengths and avoid weaknesses, become a well-known sales office, and grow with the enterprise.

I made some innovations, and improved my comprehensive quality and ability by integrating knowledge, ability, wisdom and other factors in practice, so as to lay a good foundation for the success of my career. Thank the internship unit for providing me with this internship opportunity! Thanks to the company's deputy director, supervision engineer, measurement engineer and laboratory director for their teaching and cultivation! Thank my colleagues for their help!

1, the internship harvest on the construction site. During the production practice, I learned a lot. I had personal inspection experience from all aspects of tunnel construction, and learned about the tunnel construction technology and process.

2. I learned about important construction projects. The whole concrete structure engineering includes earthwork engineering, reinforcement engineering, formwork engineering and concrete engineering. The following will summarize the knowledge I learned in the internship and the projects I participated in:

2. Earthwork excavation. Because the quality of surrounding rock directly determines the support parameters, it is also the first key project of earthwork, and it is very important to do a good job of excavation. When earthwork is excavated, under-excavation will affect the thickness of support, and over-excavation will easily lead to cavities, which will also affect the stability of surrounding rock.

2, 2 know the reinforcement engineering. Reinforcement is the skeleton of reinforced concrete structure, which is integrated with concrete by means of gripping force. Reinforcement engineering is one of the three major projects of concrete structure engineering.

According to their functions in the structure, the reinforced concrete structures can be divided into the following types: compressive reinforcement, tensile reinforcement, erect steel, distributed reinforcement, stirrups, etc. According to their functions, the reinforced concrete structures can be divided into the following types:

1. Stress reinforcement-the reinforced concrete structures that bear tensile and compressive stresses.

2. Stirrup-it bears part of the diagonal tensile stress and fixes the position of the stress bar, and is mostly used to connect two rows of reinforcement bars in the lining.

3. Erection of vertical bars-used to fix the position of steel hoops in the beam and form the steel skeleton in the beam.

4. Distribution bar-used to be arranged vertically with the stress bar of the plate, to evenly transfer the bearing weight to the stress bar, to fix the position of the stress bar, and to resist the temperature deformation caused by thermal expansion and contraction.

5. Others —— structural bars configured due to structural requirements of members or construction and installation needs. Such as waist tendons, embedded anchor tendons and rings. At present, hot-rolled round bars (commonly known as round bars), hot-rolled ribbed bars (commonly known as rebar), cold-rolled twisted bars and cold-drawn low-carbon steel wires are commonly used as reinforcement. Among them, the former two are the most widely used, and the latter two are generally used in high-strength concrete. The round steel is identified as hpb235, and the commonly used diameters are 6, 5, 8, 1 and 12. The thicker steel is not often used, and 6, 5 and 8 are the most commonly used, and are generally used as stirrups. 8, 1, and 12 generally make distribution bars. The common logo of rebar is hrb335, and the commonly used diameters are 12, 14, 18, 2, 22, 25, and 2. The coarser rebar generally appears in mass concrete engineering, and it is not commonly used. Generally, the rebar below 25 is the most commonly used. Because it is difficult to check the quality of steel bars after concrete pouring, the steel bar project is a concealed project, which needs to be strictly checked in the construction process and the necessary inspection and acceptance system should be established. In order to ensure the normal work of the concrete structure in the use stage, the specifications and positions of the steel bars must be consistent with the structural construction drawing during the construction of the steel bar project. In engineering, steel bars often have to be connected due to insufficient length or the requirements of construction technology. Therefore, the connection of reinforcement is an important link in reinforcement engineering.

2, 3 know the template project. Formwork engineering of concrete structure is a very important part of concrete molding construction. The formwork we are talking about actually includes two parts, one is the formwork to form the shape and design size of concrete members, and the other is the support system to ensure the shape, size and spatial position of the formwork. The formwork shall have a certain strength and rigidity to ensure that the concrete will not be damaged or deformed under the action of self-weight, construction load and lateral pressure of concrete. The supporting system should not only ensure the accuracy of the spatial position of the formwork, but also bear the self-weight of the formwork and concrete and the construction load, so it should also have sufficient strength, rigidity and stability to ensure that it will not sink, deform or destroy under the action of the upper load.

templates are also very different in materials and types. Generally, it can be divided into wood formwork, steel formwork and plywood. Most of this project uses steel formwork, which is not easy to deform. The role of formwork is that in the process of structural construction, the concrete that has just been mixed from the mixer is in liquid state and needs to be poured into the model number with the same shape and size as the component, so that the required structural component can be formed after the concrete is solidified and hardened. The formwork is the model for forming the reinforced concrete structure or component.

The formwork support system is a temporary structure that ensures the shape and position of the formwork panel and bears the self-weight of formwork, steel bars, newly poured concrete and construction load. The vertical support of the formwork mainly includes pipe supports assembled in a scattered way, steel pillars that can be used independently with height adjustable devices, and portal frames. Before the template is installed, it is necessary to design and calculate the template. Generally, there is no need to design or check the commonly used stereotypes within its scope of application. Generally, experienced contractors and workers know how to install them. However, for some special structures, new system templates or general templates beyond the scope of application, they should be designed or checked. For example, the hat brim of tunnel portal, etc., otherwise it is easy to swell.

1. Progress of Tunnel Construction

The total length of the three single lines of the tunnel in my project is 1981 meters, and the left line of the No.1 tunnel in Jiulongao is 26 meters long, with the initial lining of 26 meters and the inverted arch construction of 1 meters; The right line is 285 meters long and 1 meters into the tunnel. Because the landslide at the top of the cave has been changing, the retaining wall is built first and then into the tunnel. Liujiaao Tunnel started relatively late. The left line is 37 meters long, the initial lining has been 19 meters, the right line is 32 meters long, and the initial lining has been 21 meters. These two tunnels belong to soft rocks and need blasting construction. The left line of No.2 tunnel in Jiulong 'ao is 367 meters long, with 293 meters of initial lining, 7 meters of inverted arch construction and 174 meters of the first tunnel. The right line is 379 meters long, and the initial lining has been 228 meters. The first tunnel is 176 meters long and the inverted arch is 6 meters long.

Summary of Tunnel Work in 223 4

The year of 2xx is coming to an end. Memories of this year are both busy and rewarding, which makes me feel both happy and worried. I have been doing quality inspection in the injection molding workshop for more than 3 years, and my position does have some work pressure, but for me, no pressure means no motivation. As a quality inspector, in order to make myself grow faster and improve my work, I have made the following work summaries:

1. Check the quality in my work

As a quality inspector, I should not only master professional testing knowledge, but also be careful to find problems, find problems and solve them. So this year's on-site quality work has benefited me a lot. Before inspection, you should learn to understand the product drawings and try the product. According to the requirements of quality process, do a good job of supervision, find and correct the problems existing in the inspection process. Cooperate with the operator to make a comprehensive inspection of the product quality, and put forward and correct the problems in the product in time. Follow-up and check the process of special products to ensure that each process is qualified. Strictly control the quality of the incoming products and summarize and analyze the results afterwards, so as to facilitate the continuous improvement of the work. Before leaving work every day, do a good job of handing over the quality problems in the inspection process. Record the merits of the problems that are easy to appear in the future during the inspection process, and constantly improve the personal professional inspection level; Seriously reflect the quality problems existing in the site and the problems that need to be solved by the company.

2. Shortcomings and problems in the work

1. There is still a certain gap in product quality requirements, which leads to the phenomenon of returning goods in small batches. On the one hand, due to the lack of meticulous personal inspection and sufficient professional knowledge, on the other hand, when the workload is large and the time is long, the work efficiency is not high.

2. I'm not sure whether it is clear or not when I find quality problems, and I'm not decisive enough, and I need the help of leaders when I deal with some things.

3. Due to the shortage of quality inspection staff, long working hours and increased workload, if one person asks for leave, no one will replace him.

3. Work plan and improvement for next year

1. I will further develop my advantages, improve my shortcomings and do my best to do my job. It is necessary to maintain a good mental state and carry forward the spirit of hard work, advancing despite difficulties, striving for perfection, being rigorous and meticulous, learning and enterprising, and daring to struggle. Clear up work ideas and improve work efficiency.

2. Before the inspection, I must first know the products that need to be inspected, and I should make preparations in advance before the inspection, and carefully supervise the inspection.

finally, our company pays attention to the cultivation of employees' skills, team spirit and enthusiasm for working actively for humanized management. I believe that I will definitely grow up in the development of your big family, and we will definitely grow up!
