Embodiment Construction
[0023] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0024] See Figure 1-Figure 5 , a large-volume foundation floor construction method, the specific method is as follows:
[0025] 1) Waterproofing of the foundation pit: including drainage outside the pit and drainage inside the pit; drainage outside the pit: after the earthwork of the deep foundation pit is excavated, a water retaining dam 2 is set around the foundation pit, and a drainage ditch 3 is set outside the water retaining dam 2 to prevent Water from the site outside the pit flows into the foundation pit; drainage in the pit: slope protection 7 is set at the position where the elevation of the floor changes, drainage ditch 3 is set at the upper end of slope protection 7, drainage ditch 3 is set at the bottom of slope protection 7, drainage ditch 3 at the bottom of slope protection 7 is connected with slope protection Between 7, slope pro...

The invention discloses a large-sized foundation slab construction method and construction structure. The construction structure comprises a construction waterproof structure and pump pipe scaffolds.The construction waterproof structure comprises water retaining counter dams, drainage ditches, slope revetments, slope protection piles and waterproof guide walls. The water retaining counter dams are arranged on the periphery of a foundation pit. The drainage ditches are formed in the outer sides of the water retaining counter dams. Slopes are arranged between slabs of different elevations in the foundation pit, and the slope revetments of cement mortar are paved on the slopes correspondingly. The drainage ditches are formed in the upper ends and the bottoms of the slope revetments correspondingly. The slope protection piles are additionally arranged between the drainage ditches at the bottoms of the slope revetments and the slope revetments correspondingly. The waterproof guide walls are arranged in the positions, close to upper slopes and the drainage pitches, in the slabs correspondingly. The pump pipe scaffolds are erected on slab cushion layers correspondingly. Compared with theprior art, the large-sized foundation slab construction method and construction structure have the beneficial effects that the large-sized foundation slab construction method is a large-thickness large-area foundation pit slab foundation concrete pouring construction method, the construction progress is accelerated, and construction quality is guaranteed.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a large-volume foundation floor construction method and construction structure. Background technique [0002] A construction company undertook the construction of a construction project in Tangshan City, Hebei Province. The project is a high-rise building with 33 floors above ground and one floor below ground for commercial and residential purposes. The thickness of the foundation slab of this construction project is up to 1200mm, which involves the construction and pouring of large-thickness and large-area concrete foundations. Due to the large thickness of the base plate and the large construction area, it is difficult to construct in order to prevent cold joints during the pouring process and reduce the construction quality. Contents of the invention [0003] The object of the present invention is to provide a large-volume foundation floor construction method ...
