Abstract
The utility model provides an underground space roof subsides post-cast strip enclosed construction in advance, aims at solving the construction of underground space roof subsides post-cast strip among the prior art and need wait to subside the stable construction of carrying on waterproof layer, backfill etc. again and lead to the defect that the engineering period is long, provides an underground space roof subsides post-cast strip enclosed construction in advance, including the subsides post-cast strip of reserving, embedded the stagnant water steel sheet that sets up in the left and right sides edge of subsiding the post-cast strip, lay the supporting template in the subsidence space bottom surface of subsiding the post-cast strip, hug closely the closing cap that sets up in the subsidence space upper portion of subsiding the post-cast strip, through set up the pouring hole on the closing cap and the concrete placement outer tube that subsides the subsidence space upper portion of post-cast strip and communicate, concrete placement. The method is mainly used for construction of the top plate settlement post-cast strip of the underground space, and compared with the traditional construction scheme, the construction time can be greatly shortened.
Description
Technical Field
The invention relates to the technical field of buildings, in particular to an advanced sealing structure of a top plate settlement post-cast strip of an underground space.
Background
the underground space and the main building around the underground space have large pressure difference to the base due to dead weight, and meanwhile, when the length of the underground space structure in the longitudinal direction and the transverse direction exceeds the specification of the maximum interval of the standard expansion joint, temporary construction joints are required to be reserved at corresponding positions to digest, subside, shrink and deform, and concrete is used for pouring compactly after a period of time. The settlement joint must be sealed at the main building structure, and the fitment is built by laying bricks or stones and is accomplished, can seal after the main building subsides stably, then at the top surface construction waterproof layer of underground space, backfill soil, pipeline and afforestation etc. this kind of construction method has a long term, is unfavorable for the arrangement of the total time limit of construction.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the utility model provides an underground space roof post-cast strip enclosed construction in advance can seal underground space roof post-cast strip in advance, when guaranteeing major structure safety, reduces the engineering time.
The technical scheme adopted by the invention is as follows: the utility model provides an underground space roof subsides post-cast strip enclosed construction in advance, includes the subsides post-cast strip of reservation, embedded setting is at the stagnant water steel sheet of subsiding the left and right sides edge of post-cast strip, lays the support template in the subsidence space bottom surface of subsiding the post-cast strip, hugs closely the closing cap who sets up on the subsidence space upper portion of subsiding the post-cast strip, through setting up the concrete placement outer tube that pouring hole and the subsidence space intercommunication of subsiding the post-cast strip on the closing cap, concrete placement outer tube perpendicular to closing cap place plane.
The invention has the beneficial effects that: the invention can seal the post-cast strip of the top plate of the underground space in advance, and reduce the construction time while ensuring the safety of the main structure.
The invention is further described with reference to the following figures and detailed description.
Drawings
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view showing a connection relationship between a concrete-poured outer pipe and a concrete-poured inner pipe according to the present invention.
In the attached drawing, 1 is a settlement space, 2 is a supporting template, 3 is a water steel plate, 4 is a closed cover plate, 4-1 is a pouring hole, 5 is a concrete pouring outer pipe, 5-1 is a limiting boss, 6 is a concrete pouring inner pipe, 7 is a waterproof layer, and 8 is backfill soil.
Detailed Description
Referring to the attached drawing 1, the underground space roof settlement post-cast strip advanced sealing structure comprises a reserved settlement post-cast strip, water stop steel plates 3 embedded into the edges of the left side and the right side of the settlement post-cast strip, a supporting template 2 laid on the bottom surface of the settlement space 1 of the settlement post-cast strip, a sealing cover plate 4 tightly attached to the upper portion of the settlement space 1 of the settlement post-cast strip, and a concrete pouring outer pipe 5 communicated with the settlement space 1 of the settlement post-cast strip through a pouring hole 4-1 formed in the sealing cover plate 4, wherein the concrete pouring outer pipe 5 is perpendicular to the plane of the sealing cover plate 4.
During construction, after the sealing cover plate 4 is paved on the reserved sedimentation post-cast strip when the structure is not settled stably, the waterproof layer 7 can be constructed on the sealing cover plate 4 in advance, the backfill soil 8 is filled, and the self-compacting cement sealing post-cast strip is built from the concrete pouring outer pipe 5 after the sedimentation is stable, so that the problem that the traditional construction needs to wait for 45 days to two months for sedimentation stability and then perform subsequent construction of the waterproof layer 7, the backfill soil 8 and the like is solved, and the construction period is shortened.
In view of the problem that the outer concrete pouring pipe 5 cannot be taken out of the closing cover 4 after the self-compacting cement and the backfill are poured, the present embodiment further includes an inner concrete pouring pipe 6 having an outer diameter smaller than the inner diameter of the outer concrete pouring pipe 5, and the inner concrete pouring pipe 6 is sleeved in the outer concrete pouring pipe 5 to form a connecting structure capable of sliding along the axial direction of the outer concrete pouring pipe 5. After the concrete pouring outer pipe 5 is arranged, the self-compacting cement is poured from the concrete pouring outer pipe 5 instead of the concrete pouring inner pipe 6, the concrete pouring inner pipe 6 can be directly covered when backfilling, and the concrete pouring outer pipe 5 can be conveniently taken out after the self-compacting cement is poured.
In the embodiment, as shown in fig. 2, a limiting boss 5-1 for limiting the sliding position of the concrete pouring inner pipe 6 is further arranged on the inner diameter of the concrete pouring outer pipe 5, and the limiting boss 5-1 is preferably in a circular ring structure.
