To achieve the goals above, the utility model provides following technical scheme:
A kind of late poured band structure of outer wall of basement, comprising to casting area, described to casting area two sides is to have poured Wall, two have poured and are respectively provided with a sleeper in wall, and the wall that poured of two sides respectively extends towards to form two along outside A opposite evagination ennation, towards upstream face, each sleeper is located to be corresponded to the outer convex direction of two ennations It pours at the variable cross-section of wall, deformation joint is equipped between two ennations, be equipped with water sealing part in the deformation joint, two It is described to have poured wall and the upstream face of deformation joint is equipped with waterproof construction.
Using a kind of late poured band structure of outer wall of basement described in the utility model, level of ground water is very high, hydraulic pressure very In the case where big, earth lateral pressure is also very big after backfill, and using sleeper is added at variable cross-section, the variable cross-section is described poured At the evagination ennation of walling body, it can effectively avoid and not live earth lateral pressure after backfill because bearing due to crack, and then poured after causing Danger with leak infiltration, simultaneously because the deformation joint between two ennations is located at areas outside to be poured, the deformation joint In be equipped with water sealing part, can construct in advance outside waterproof construction, make basement post-pouring zone from foundation pit outside underground water and The influence of silt reduces the exposure duration of foundation pit, ensures construction safety, saves the construction period, construction cost is reduced, to be poured It builds when region is poured and only needs single side formwork, the construction operation being particularly suitable under narrow place.
Preferably, described to be equipped with catch pit by casting area.
It is further preferred that the catch pit is set in bottom plate rear pouring tape, the width and bottom plate rear pouring tape of the catch pit It is of same size, the bottom surface of the catch pit is 500-600mm lower than the bottom surface of bottom plate rear pouring tape.
Using above-mentioned set-up mode, i.e., in the bottom plate rear pouring tape of the area inside to be poured carry out part dig deep at The catch pit reduces shoveling amount, saves space, advantageously ensure that the drying in post-cast strip, avoid reserved reinforcing bar and steel plate It is impregnated, is prevented by the destruction for building slag.Later period backfills catch pit before bottom plate rear pouring tape closing, using plain concrete, has Effect saves amount of reinforcement.
Preferably, the water sealing part includes rubber fastening band and extruded polystyrene board, the both ends point of the rubber fastening band Lacing wire is not connected with it.Rubber fastening band both ends are fixed by lacing wire, effectively prevent shifting.
Preferably, the waterproof construction includes waterproof layer and protective layer.
It is further preferred that the waterproof construction also includes additional waterproofing layer, the additional waterproofing layer is set to the deformation The upstream face of seam, the additional waterproofing layer are located on the inside of the waterproof layer.
It preferably, also include steel plate for sealing water, the steel plate for sealing water is set to casting area and has poured between wall, described The setting direction of steel plate for sealing water is perpendicular to the extending direction to casting area.
It is further preferred that the steel plate for sealing water with a thickness of 3-5mm.
It is further preferred that the bending side of the steel plate for sealing water is towards upstream face.
The steel plate for sealing water is along the center line anchoring to casting area extending direction.
In conclusion compared with prior art, the utility model has the beneficial effects that
1, using a kind of late poured band structure of outer wall of basement described in the utility model, ultra-deep base can be effectively applicable to Hole or the higher construction environment of level of ground water prevent post-pouring belt of outer wall structure caused by hydraulic pressure and earth lateral pressure are excessive after backfilling Cracking and leak, reduce the exposure duration of deep basal pit, ensure construction safety, save the construction period, reduce construction cost, are treating Single side formwork is only needed when casting area is poured, the construction operation being particularly suitable under narrow place.
2, part is carried out in bottom plate rear pouring tape and digs deep into the catch pit, is reduced shoveling amount, is saved space, be conducive to Guarantee the drying in post-cast strip, avoids reserved reinforcing bar and steel plate from being impregnated, prevent by the destruction for building slag, the later period is in bottom plate Before the closing of post-cast strip, catch pit is backfilled using plain concrete, effectively saving amount of reinforcement.
