Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and particularly relates to a waterproof structure at a supporting plate replacement belt of a basement main structure. Background Art

[0002] The basement is an important space in a construction project, and deep foundation pit-type basements have gradually become one of the necessary contents of a construction project. The internal support of the space is an important construction component to keep the structure of the basement in a fixed state. The material of the supporting structure is generally reinforced concrete.

[0003] After the construction of the foundation pit support structure and the excavation of the earthwork are completed, the underground main structure will undergo the layer-by-layer removal of the internal supports during the construction process from bottom to top. The water and soil pressure on the outside of the retaining structure will gradually transfer to the main structure that has just been completed. Therefore, before removal, other support structures need to be used to replace the internal supports to continue to support the retaining structure, which is called "replacing the support". The replacement support strip is usually at the same height as the floor slab, with one end fixed to the outer wall of the basement and the other end connected to the retaining structure through a hanger. The existence of the replacement support strip causes the waterproofing of the main structure to be discontinuous, becoming a weak point in waterproofing. Although there is a method of pre-laying waterproof membrane between the replacement support strip and the retaining structure, and then bending the waterproof membrane to the replacement support strip for connection, the waterproof membrane is a flexible material, which is not conducive to the force transmission of the replacement support structure, and has an adverse effect on the deformation control of the retaining structure.
