Description

Waterproof structure of post-pouring belt of bottom plate of cracking monitoring basement Technical Field The utility model relates to the technical field of basement waterproofing, in particular to a waterproof structure of a post-pouring zone of a bottom plate of a crack monitoring basement. Background The post-cast strip is used for preventing the cast-in-situ reinforced concrete structure from harmful cracks possibly caused by uneven temperature and shrinkage, temporary construction joints are reserved at corresponding positions of a plate (comprising a foundation slab), a wall and a beam according to construction specification requirements, the structure is temporarily divided into a plurality of parts, the construction joints are cast into concrete after a plurality of times after the internal shrinkage of the components, and the structure is connected into a whole. Post-cast strip is an effective measure for solving the sedimentation difference and reducing shrinkage stress, so that the post-cast strip is more applied in engineering. As shown in figure 3, in the post-cast strip structure commonly used in the prior art, as joint seams exist on two sides of the post-cast strip (namely joints between the pre-cast concrete and the post-cast concrete), when the concrete structures on two sides shrink or asynchronously subside, the sealing degree of the joint seams can fail to different degrees, and after the post-cast strip is put into use, water seepage phenomenon can occur if groundwater under the post-cast strip is increased. The prior art generally adopts the waterproof construction that sets up the steel sheet waterstop in joint department, and steel sheet waterstop one side is pre-buried in earlier watering concrete layer, and the opposite side is pre-buried in later watering concrete layer, cuts off the joint to prevent groundwater and upwards permeate along the joint, however because the concrete structure of joint both sides can appear expending with heat and contract with cold along with environment or geological change, especially when ambient temperature drops, the concrete takes place to shrink, the joint increases, and then destroys the waterproof leakproofness of joint, still has the hidden danger of oozing water, and can't accurate monitoring maintain. It is therefore necessary to develop a waterproof construction for a post-cast strip for a floor of a crack monitoring basement.
