Description
Technical Field
The invention relates to a top plate post-cast strip sealing process, in particular to a top plate post-cast strip advanced water stopping structure.
Background
The post-cast strip is the key of the construction technology of cast-in-place concrete of the top plate of the underground garage and is an important guarantee for preventing the cast-in-place concrete structure from cracking and leaking due to uneven settlement of the underground garage. Therefore, how to avoid cracking and leakage at the post-cast strip in a cast-in-place concrete structure is an important subject faced by civil engineering engineers, and the improvement of the process directly promotes the development of the post-cast strip construction process.
The structural safety and the use function of the underground garage are ensured in order to ensure that the roof of the garage is cracked and leaked due to uneven settlement in group buildings or large-span garages. In practical engineering, the underground garage is generally used for avoiding the situation by adopting a method of arranging a post-cast strip. This is usually solved by providing a form of post-cast strip. However, these post-cast strips increase the leakage risk due to the existence of construction joints, and are prone to be the most main part of the leakage of the top plate of the underground garage due to long-term exposure of the construction joints, corrosion of steel bars and water-stop steel plates, and subjective uncertainty of later manual operation. Therefore, the existing post-cast strip technology should be improved on the water-stopping design, and the increase of leakage caused by long-term exposure of construction joints, corrosion of steel bars and water-stopping steel plates and subjective uncertainty of later manual operation is avoided as much as possible.
The post-cast strip is composed of steel bars, concrete and a water stop steel plate, and the post-cast strip can be cast after the casting time of the post-cast strip is separated from the main body for a period of time. Before that, the water stop steel plate of the post-cast strip is eroded by the natural environment for a long time. Before the concrete of the post-cast strip is poured, the two sides of the post-cast strip are both cantilever structures, the loads on the two sides of the post-cast strip must be strictly controlled, otherwise, the instability and the damage under the designed section can be caused due to the increase of the negative bending moment. At present, the problems of cracking and leakage of a top plate of a ground reservoir caused by corrosion of a steel bar and a water stop steel plate due to long-term exposure of a construction joint and subjective uncertainty of later manual operation exist in post-cast strip construction. The core problem of ensuring that the post-cast strip does not leak is to solve the problem of long-term exposure of construction joints so as to reduce the later hidden danger.
Therefore, there is a need for an advanced water stopping technique that protects the post-cast strip portion from long-term exposure to the elements and reduces the rolling damage to the construction joint location due to construction transportation.
