[0003] The side formwork of the pouring belt after the advanced water stop is affected by the upper and lower steel mesh and cannot be fully assembled, and it is very difficult to remove the formwork after the concrete pouring is completed
It leads to a large cost of labor and materials, and the construction quality is not easy to guarantee
Now the traditional method is to use wooden molds for on-site cutting, processing, production and installation. Since the wooden molds are all damaged during the dismantling process, they cannot be turned around once they are used one time, and the materials used are wasted.

The invention discloses a construction method for a foundation slab combined-type side formwork pre-waterstop post-cast strip, and relates to the technical field of foundation engineering. The construction method includes the following steps that (1) a cushion layer, a waterproof layer and a leveling layer are constructed; (2) an externally-bonded rubber waterstop band is installed; (3) a steel reinforcement framework is bundled and installed; (4) an extruded polystyrene board is installed; (5) a post-cast strip reinforced layer is poured; (6) a first waterstop bar is installed; (7) a post-cast strip side formwork is installed; (8) a waterstop steel plate is installed; (9) a foundation slab is poured; (10) a water retaining stripe is installed; (11) a water storage bag is installed; (12) aprefabricated stick is installed; (13) a second waterstop bar is installed; and (14) a waterstop cover plate is installed. According to the construction method for the foundation slab combined-type side formwork pre-waterstop post-cast strip, the waterproof effect of a post-cast strip foundation pit can be fully guaranteed through a tight waterproof structure, and precipitation power cost is reduced.
Description
technical field [0001] The invention relates to the technical field of foundation engineering construction, in particular to the installation and construction of a composite side form of a cast-in-situ concrete structure foundation bottom plate with an advanced water stop and post-cast belt. Background technique [0002] In recent years, with the development of the construction industry, the post-casting belt construction technology has been frequently used in the construction of high-rise buildings, but the traditional post-casting belt technology will increase the cost of project precipitation, long-term exposure will cause cracks, and the safety hazards of legacy projects will affect the follow-up Process construction. In order to overcome the above-mentioned defects, advanced water-stop technology of post-pouring belt came into being. This technology is based on water buoyancy, water and soil pressure, foundation reaction force, building load, etc. A waterproof method. ...
