Introduction of retaining wall construction technology?

When it comes to the construction technology of retaining wall, the relevant architects are still relatively unfamiliar. What is the basic situation of retaining wall construction technology? What are the relevant regulations and requirements for main masonry? The following is the basic content of "Architect's Retaining Wall Construction Technology" by Zhong Da Consulting Company. The specific content is as follows:

Through combing the relevant contents, Zhong Da Consulting Company has specified the following contents of retaining wall construction technology:

The main construction technology of retaining wall includes: stone requirements, cementing material requirements, masonry requirements, masonry methods and other related contents, among which the masonry requirements for construction enterprises are as follows:

(1) Before the compressive strength of masonry reaches 2.5Mpa, the upper masonry shall not be prepared.

(2) masonry mortar masonry method must be adopted. When laying, stones should be laid in layers, staggered up and down, and laid inside and outside. The joint width of masonry shall meet the requirements in the following table:

Grading joint (cm)

Strip stone

Mortar masonry flat joint 1.5 ~ 22 ~ 2.5

Vertical joint 2 ~ 3 2 ~ 4

(3) Before paving, the stone should be wetted with water to make its surface fully absorb water, but no residual water is allowed. The exposed surface of masonry shall be maintained within 12 to 18 hours after masonry. Before continuing masonry, the floating ballast on the surface of masonry should be removed before masonry.

(4) When building cement mortar masonry, the masonry should face downwards, and shake or knock it properly to make it stable; It is forbidden to stick stones without slurry. After filling mortar, insert it with flat iron and tamp it until the surface is full of slurry. Within the same masonry layer, adjacent stones should be laid in staggered joints, and there should be no straight joints downstream. Adjacent paving stones should also be staggered and overlapped to avoid vertical straight joints. When necessary, the Shi Ding can be erected regularly.

(5) Wet stone shall not be used in rainy day construction, so as to avoid mortar flowing affecting masonry quality and protect the surface. If there is no canopy and the rainfall is more than 5 mm, the masonry operation should be stopped.
