Background
In recent years, it has been comparatively extensive a marketing means that promotes real estate sales volume to construct basement roof gardens and pipe network in advance as the show area, but in gardens show area work progress, often because the major structure subsides still not stable yet, subsides post-cast strip and can not seal in advance, leads to the gardens show area can not fully demonstrate comprehensively, and the bandwagon effect that produces does not reach the effect that the developer expects, and the mode of handling usually is two kinds generally:
the utility model provides a, the local post-cast strip that directly influences garden construction pours in advance and seals, though garden construction advances to the field in advance, and gardens show area effect reaches anticipated effect, nevertheless major structure subsides and inevitably leads to this position post-cast strip concrete fracture infiltration, and the fracture scope is not limited to post-cast strip position, and the position scope of mending leakage in the future is big, need carry out the concrete leakage many times even and mend, and the antiseep is with high costs, and the corruption influence of a large amount of infiltration of concrete structure to the reinforcing bar is great.
Secondly, lay the steel sheet in post-cast strip position, reserve the waterproofing position after, directly carry out the garden construction after accomplishing the waterproof and protective layer construction of peripheral basement roof, later stage major structure subsides stably the back, excavate again and construct gardens and the pipe network of accomplishing, uncover post-cast strip steel sheet, clear up post-cast strip construction joint back, pour post-cast strip concrete, do water-proofing and protective layer again, will dig out the gardens show area and the pipe network secondary construction of destruction and resume. Although the method avoids water seepage repair of a post-cast strip, the entering excavation of large machinery in the garden display area increases the additional garden site damage and maintenance, earthwork excavation, pipe network and secondary construction cost, and the cost also includes the safe and civilized construction cost in the process.
Therefore, the traditional construction method for closing the post-cast strip in advance cannot meet the modern construction requirements.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model aims at providing a can solve the tradition and subside the unable in time confined difficult problem of post-cast strip because of gardens construction of advancing to the field in advance, also for reducing gardens and pipe network secondary construction, basement roof infiltration repair have practiced thrift a large amount of construction cost subside post-cast strip closed structure in advance.
The utility model discloses a realize through following technical scheme:
