Anti-floating waterproof structure of underground building and construction method

Abstract

The invention belongs to the technical field of engineering construction, and particularly relates to an anti-floating waterproof structure of an underground building. The anti-floating waterproof structure comprises a first force transmission structure and a second force transmission structure, and a first bottom plate and a second bottom plate which are tightly connected are arranged at the bottom of a second phase main body structure; a first phase envelope structure is arranged on the periphery of a first phase main body structure connected with the second phase main body structure; the second force transmission structure is between the top of the first phase envelope structure and the second bottom plate; the first force transmission structure is below the first bottom plate; one side of the first force transmission structure is appressed to the first phase envelope structure; the first force transmission structure and the second force transmission structure are in tight embodiment; a waterproof coiled material is arranged between the first force transmission structure and the second force transmission structure; and the two sides of the waterproof coiled material extend to be connected with waterproof coiled materials on the peripheries of the first phase main body structure and the second phase main body structure. The invention further provides a construction method of the anti-floating waterproof structure. According to the anti-floating waterproof structure, the waterproof coiled material is continuously laid at connection parts while floating resistance is achieved, anti-floating capacity and waterproof effect of the building are improved, and the anti-floating waterproof structure has the advantages of simple structure, easy construction and low cost.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and more specifically relates to an anti-floating and waterproof structure and construction method of an underground building, which can provide anti-buoyancy while ensuring continuous laying of waterproof coiled materials, so as to meet the anti-floating and waterproof structure of underground buildings. Float and waterproof needs. Background technique [0002] In the construction of underground structure engineering, due to the influence of factors such as phased traffic evacuation and pipeline relocation requirements, surrounding environmental protection, construction period and other factors, the underground structure is often constructed in phases, and the foundation pit is supported in sections. Usually, the first-stage enclosure structure (drilling hole pouring pile, underground diaphragm wall) as the sub-pit pile of the foundation pit. Within the connection range between...

Problems solved by technology

However, further research shows that this method has the following defects and deficiencies: (1) The waterproof membrane is interrupted at the anchoring position, and the structure needs special treatment for waterproofing; (2) The connection is close to the construction joints of the main structure of the first phase and the main structure of the second phase , the waterproof effect cannot be guaranteed
