Detailed Description
In order to deepen the understanding of the present invention, the following embodiments will be combined to make the present invention do further details, and the present embodiment is only used for explaining the present invention, and does not constitute the limitation of the protection scope of the present invention.
According to the drawings of fig. 1 and fig. 2, the embodiment provides a side wall post-cast strip plugging structure, which comprises a concrete outer wall 1, a post-cast strip, a cover plate 3 and a water-stop steel plate 21, wherein the water-stop steel plate 21 is arranged in the middle of the concrete outer wall 1 and the post-cast strip in a crossing manner, and the water-stop steel plate 21 mainly prevents underground water from reversely permeating into the concrete outer wall 1; the cover plate 3 is arranged on the outer side of the post-cast strip and the concrete outer wall 1, the periphery of the cover plate 3 is fixedly connected with the concrete outer wall 1 through expansion bolts 5, the cover plate 3 is quickly assembled through a simple threaded connection structure, and the exposure time of the side slope wall of the foundation pit is reduced; an expansion water stop strip 6 is arranged between the cover plate 3 and the concrete outer wall 1, the expansion water stop strip 6 is positioned between the bolt and the post-pouring strip, the expansion water stop strips 6 are arranged on two opposite side edges of the post-pouring strip, the cover plate 3 is arranged in a full-length mode, and the expansion water stop strips 6 on the two side edges of the post-pouring strip mainly prevent underground water from leaking to the post-pouring strip along the cover plate 3; the connecting end of the concrete outer wall 1 and the cover plate 3 is filled with waterproof mortar 40, and a waterproof roll 41 is bonded on the outer layer of the waterproof mortar 40.
Therefore, the cover plate is arranged in the post-cast strip and the concrete external wall plate and serves as a supporting and blocking template when the post-cast strip concrete is poured, and a retaining wall does not need to be additionally constructed; under the support of the cover plate, corresponding filling materials can be backfilled in gaps among the concrete outer wall, the outer side of the cover plate and the foundation pit slope wall to stabilize the foundation pit slope wall, post-cast strip pouring operation is smoothly carried out, the operation time is greatly reduced, the exposure duration of the foundation pit slope wall is reduced, and the risk of collapse is reduced; in addition, waterproofing system that waterproofing membrane, waterproof mortar, inflation sealing rod, stagnant water steel sheet are constituteed can prevent that groundwater source from leaking to the post-cast strip, and simultaneously, the apron can resist groundwater source's impact, prevents and treats that groundwater source from flowing into the basement through the post-cast strip.
Because the width of the post-cast strip is different, the width of the cover plate 3 is 200mm wider than that of each of the two sides of the post-cast strip, so that the cover plate 3 can always protect the post-cast strip; through holes are arranged on the cover plate 3 at intervals in the transverse direction and the longitudinal direction, and bolts penetrate through the through holes and are fixed with the concrete outer wall 1 through threads; in order to prevent water from penetrating to the top of the concrete outer wall 1 through the bolts, the assembled length of the bolts is extended to the positions 1/3-2/3 of the interior of the concrete outer wall 1, so that the bolts can be stably connected to the interior of the concrete outer wall 1 without penetrating through the outer wall.
In order to enhance the protection of the water-stopping system, the groove of the water-stopping steel plate 21 faces the cover plate 3, the construction is focused on the pouring of the post-pouring belt, and the water-stopping steel plate 21 needs to be downward to prevent the interference of the underground water source.
In order to enable the cover plates 3 to meet different side wall heights, the height required by the side walls can be formed by overlapping the cover plates 3, the height of the cover plates 3 is the same as that of the side walls, and the cover plates 3 are a plurality of blocks and have the same shape and size; in addition, waterproof glue is required to be coated on the edge gap between the superposed cover plates 3, so that the flowing space of water resources is reduced, and the waterproof requirement is met.
When the width of the post-cast strip is wide, the middle part of the cover plate 3 deforms due to the influence of deflection, and when large deformation occurs under the action of external force, the backfilling process in the gap between the concrete outer wall 1 and the side slope wall of the foundation pit is further influenced; referring to fig. 2, the cover plate 3 on the side close to the post-cast steel bar 20 is connected with the suspension ring 7 through threads or is fixed by welding, then two connecting rods 70 are movably connected on the suspension ring 7, the other ends of the connecting rods 70 are in a hook shape, the two connecting rods 70 are respectively buckled on the post-cast steel bar 20, the length of the connecting rods 70 needs to be measured and customized in advance, so that after the buckling is realized, the positions of the connecting rods 70 are relatively fixed, and the suspension ring 7 and the connecting rods 70 play a role in dispersing the stress of the cover plate 3.
According to the weak degree of the cover plate 3, the hanging ring 7 is fixed in the middle of the full length of the cover plate 3 according to a preset distance, and the distance can be 1.5 times of the width of the post-cast strip.
The above-described embodiments are merely illustrative of the embodiments of the present invention, and do not limit the spirit and scope of the present invention. Under the prerequisite that does not deviate from the design concept of the utility model, the ordinary person in the art should fall into the protection scope of the utility model to the various changes and improvements that the technical scheme of the utility model made.
