What is the difference between end-bearing piles and friction piles?

Many people think that the difference between these two products is not very big, but only when they are in construction can they have enough knowledge and understanding to better construct. Next, I will share with you the difference between end-bearing piles and friction piles. In addition, let's talk about the construction steps of end-bearing piles. Let's take a look at the relevant knowledge. There are two kinds of pile foundations at present, end-bearing piles and friction piles. Many people think that the difference between these two products is not very big, but only when they are in construction can they have enough knowledge and understanding to better construct. Next, let's share the difference between end-bearing piles and friction piles. In addition, let's talk about the construction steps of end-bearing piles. Let's take a look at the relevant knowledge.

Difference between end-bearing pile and friction pile

End-bearing piles are transferred to solid soil or rock through piles, while friction piles transfer the gravity of buildings around the piles and in the soil below the pile ends. The load on the pile is basically supported by the friction between the pile and the soil, and the soil below the pile tip also plays a corresponding supporting role. The top load of friction pile is borne by side resistance, and the end-bearing pile is borne by end resistance.

What are the construction steps of end-bearing piles?

1. At the beginning of digging pile, measure according to the design drawings, release the pile position, and confirm that the construction has started according to the drawings and exploration report, and meet the design requirements.

2. The hole inspection originally needed to check whether the bearing stratum was satisfied according to the construction drawing and exploration report. If the bearing stratum has met the design requirements, it shall be reported to the owner and the design unit for hole inspection. If the acceptance is qualified, the signature acceptance hole pile is concealed, and the supervision company and the owner must also sign before the following project can be done. When steel bars are processed and put into excavation, all steel cages that can be made on the ground are processed; The reinforcement that should be processed in the working face should be laid in advance. After the hole-forming acceptance is qualified, the reinforcement cage should be laid immediately or the personnel should be organized to process the reinforcement cage in the working face immediately, and the inspection report should be made after completion.

3. Concrete pouring shall be carried out immediately after the fabrication and pouring of concrete pouring reinforcing cage are completed and the inspection and cleaning are completed. When pouring concrete, vibrating rods must be in place to ensure the quality of piles. The thickness of sediment at the bottom of end-bearing pile hole should be controlled below 100 mm, and the thickness of sediment at the bottom of friction pile hole should be controlled below 300 mm.

The above knowledge is mainly about the difference between end-bearing piles and friction piles. I believe that you can understand these two products through the above introduction, and also share with you the knowledge about the construction steps of end-bearing piles. You can refer to it, hoping to bring you help. If you still want to know the relevant knowledge, you can continue to pay attention to our website.
