Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular, to a method for constructing a basement ramp. Background Art

[0002] At present, the entrance to the basement of a residential area is usually a passage-type building for residents to enter and exit and store their cars, which is generally composed of a downhill ramp-type building; the downhill ramp of the basement entrance and exit, as the main passage connecting the basement to the outside world, needs to have a good waterproof structure.

[0003] However, the basement ramp is limited by the construction space, and it is difficult to complete the closed construction of external waterproofing. The ramp needs to leave construction joints due to construction reasons. If the waterproofing construction is unreasonable, it is very easy to cause ramp leakage, which will seriously affect the service life of the basement. Summary of the invention

[0004] The purpose of the present application is to provide a basement ramp construction method, which can stabilize the settlement of soil under the ramp to avoid uneven settlement, avoid ramp leakage and shorten the ramp construction period.

[0005] This application is implemented as follows:

[0006] The present application provides a basement ramp construction method, which comprises the following steps:

[0007] Carry out the pouring of basement concrete cushion layer and waterproofing of basement floor slab in sequence;

[0008] A water-stop steel plate is pre-arranged on the top of the L-shaped basement slab to be cast, and the L-shaped basement slab is cast;

[0009] Carry out waterproof construction on the side walls of the basement L-shaped slab, reserve waterproof stubble at the construction joints of the side walls of the basement L-shaped slab, and build a waterproof protective layer on the side walls of the basement L-shaped slab with bricks;

[0010] Backfill the outside of the L-shaped basement slab with soil and compact it layer by layer to below the bottom of the ramp cushion layer;

[0011] Carry out concrete pouring of ramp side walls and basement roof;

[0012] Backfill and compact the soil inside the slope of the basement;

[0013] After the soil has fully settled, pour the ramp concrete cushion and carry out ramp waterproofing construction;

[0014] Pour concrete for ramp.

[0015] In some optional implementation schemes, before pouring the basement concrete cushion layer, the basement floor is cleaned, the guide wall of the basement L-shaped slab side wall is bricked, and when the basement concrete cushion layer is constructed, the corners between the basement concrete cushion layer and the guide wall are smoothed into an arc shape.

[0016] In some optional implementation schemes, during the basement floor waterproofing construction, a non-curing asphalt waterproof coating is coated on the basement concrete cushion layer and then an SBS modified asphalt pre-laid anti-adhesive waterproof membrane is laid.

[0017] In some optional embodiments, before applying the non-curing asphalt waterproof coating, an additional layer of internal corner waterproofing is set at the internal corner between the L-shaped basement plate and the ramp to be constructed, and the additional layer of internal corner waterproofing is set 200-300mm on each side of the internal corner between the L-shaped basement plate and the ramp.

[0018] In some optional implementation schemes, when waterproofing the side walls on both sides of the basement L-shaped plate, the side walls on both sides of the basement L-shaped plate are waterproofly overlapped with the bottom plate, and the overlap length is 80-120mm.

[0019] In some optional embodiments, a 400-600mm wide external corner waterproof additional layer is set at the external corner between the basement L-shaped plate and the ramp, and the external corner waterproof additional layer is set 200-300mm on each side of the external corner between the basement L-shaped plate and the ramp structure.

[0020] In some optional implementation schemes, when waterproofing the side walls on both sides of the basement L-shaped slab, waterproof stubble is reserved at the construction joints of the side walls on both sides of the basement L-shaped slab, and the stubble length is 400-600mm. The SBS modified asphalt pre-laid anti-adhesive waterproof membrane is stubbled 200-400mm to the side walls on both sides of the basement L-shaped slab.

[0021] In some optional implementation schemes, after backfilling with bare soil on the outside of the L-shaped slab of the basement and compacting it layer by layer to the bottom surface of the ramp structure cushion layer, the ramp cantilevered bottom slab cushion layer is built, and waterproof stubble is reserved at the construction joint of the ramp cantilevered bottom slab cushion layer, so that the waterproof stubble is thrown to the ramp cantilevered bottom slab cushion layer, and waterproof construction is performed on the ramp cantilevered bottom slab cushion layer.

[0022] In some optional implementation schemes, before pouring concrete of the ramp side walls and the basement top slab, the ramp side walls and the outer side of the ramp are reinforced, and the ramp slab is reinforced longitudinally and transversely. A vertical construction joint is reserved on the ramp side walls of the basement, and a horizontal construction joint of the ramp slab is reserved at the construction site of the ramp cantilever bottom slab.

[0023] In some optional implementation schemes, after the concrete pouring of the ramp side walls and the basement roof, when the basement roof reaches the designed strength, pipes connected to the intercepting ditch are pre-buried on both sides of the ramp, and non-woven geotextiles are wrapped on the pipes after drilling holes at intervals.

[0041] Step 2: Tie the steel bars inside the basement L-shaped plate 110, and pre-arrange the water-stop steel plate 120 on the top of the basement L-shaped plate 110 to be cast, and set up the formwork of the basement L-shaped plate 110 to cast the basement L-shaped plate 110;

[0042] Step 3: waterproof the side walls on both sides of the basement L-shaped plate 110, reserve waterproof stubble at the horizontal construction joint 250 of the basement side wall, the stubble length is 400-600mm, pre-lay the SBS modified asphalt anti-adhesive waterproof membrane 180 to the side walls on both sides of the basement L-shaped plate 110, and stubble 200-400mm on the side walls, and the side walls on both sides of the basement L-shaped plate 110 are waterproofly overlapped with the basement floor, and the overlap length is 80-120mm;

[0043] A 400-600mm wide external corner waterproof additional layer 200 is provided at the external corner between the basement L-shaped plate 110 and the ramp 210, and a 200-300mm wide external corner waterproof additional layer 200 is provided on each side of the external corner between the basement L-shaped plate 110 and the ramp 210; a waterproof protective layer for the side wall of the basement L-shaped plate with a brickwork thickness of 80-120mm;

[0044] Step 4: backfill the plain soil 300 outside the basement L-shaped plate 110 and compact it layer by layer to below the bottom surface of the cushion layer of the ramp 210, pour the ramp cantilevered bottom plate cushion layer, and reserve waterproof stubble at the ramp plate horizontal construction joint 280 of the ramp cantilevered bottom plate cushion layer, so that the waterproof stubble is thrown to the ramp cantilevered bottom plate cushion layer, and waterproof construction is performed on the ramp cantilevered bottom plate cushion layer;

[0045] Step 5: tie the outer side reinforcements of the ramp side wall 160 and the ramp 210, and reinforce the ramp slab longitudinally and transversely to obtain the ramp slab transverse reinforcement 240 and the ramp slab longitudinal reinforcement 260, reserve the ramp side wall vertical construction joint 270 on the ramp side wall 160 of the basement, reserve the ramp slab horizontal construction joint 280 on the ramp cantilever bottom plate, set up the formwork and construction support of the basement top plate 230, tie the reinforcements of the basement top plate 230 after acceptance, and pour concrete to obtain the basement top plate 230 and the ramp side wall 160;

[0046] Step 6: When the basement roof 230 reaches the designed strength, PVC pipes connected to the drainage ditch 220 in the basement are pre-buried on both sides of the ramp 210, and non-woven geotextiles are wrapped after drilling holes on the PVC pipes at intervals, and the plain soil 300 inside the ramp 210 of the basement is backfilled and compacted to below the designed ramp concrete cushion 290;

[0047] Step 7: Clean the construction joints by chiseling and roughening, and pour the ramp concrete cushion layer 290 after the plain soil 300 has fully settled;

[0048] Step eight, waterproof the ramp 210 , tie the internal steel bars of the ramp 210 , overlap the internal steel bars of the ramp 210 , the ramp slab transverse reinforcement 240 , and the ramp slab longitudinal reinforcement 260 according to the specification, and pour concrete to obtain the ramp 210 .

[0049] The basement ramp construction method provided in the embodiment of the present application can effectively improve the waterproof performance of the basement and avoid leakage by pre-embedding a water-stop steel plate 120 on the top of the basement L-shaped plate 110 when constructing the basement L-shaped plate 110, and reserving waterproof stubble at the horizontal construction joint 250 of the basement side wall when constructing the side walls on both sides of the basement L-shaped plate 110. At the same time, backfilling the outer side of the basement L-shaped plate 110 and the inner side of the ramp 210 with plain soil before constructing the ramp 210 can stabilize the settlement of the soil under the ramp 210 and avoid cracking of the ramp 210 caused by uneven settlement. The concrete of the ramp 210 adopts the method of integral casting without leaving a ramp construction joint, which solves the problem of long construction period of the ramp 210.

[0051] The ramp cantilevered bottom plate cushion layer is built, and waterproof stubble is reserved at the ramp plate horizontal construction joint 280 of the ramp plate of the ramp cantilevered bottom plate cushion layer, so that the waterproof stubble is thrown to the ramp cantilevered bottom plate cushion layer, which can prevent rainwater from entering the gap of the ramp cantilevered bottom plate cushion layer through the ramp plate horizontal construction joint 280; the ramp plate horizontal stubble reinforcement 240 and the ramp plate longitudinal stubble reinforcement 260 are thrown in advance between the ramp plate and the ramp side walls 160 on both sides, and the ramp 210 is overall reinforced and poured with concrete after the ramp concrete cushion layer 290 is poured, which solves the leakage risk caused by the segmented pouring of the traditional ramp 210, ensures the self-waterproof effect of the concrete, and avoids water leakage of the ramp 210 structure. By pre-burying PVC pipes connected to the drainage ditch 220 on both sides of the ramp 210, and drilling holes in the PVC pipes at intervals and wrapping them with non-woven geotextiles, the water vapor in the basement ramp 210 can be discharged to the drainage ditch 220 through the PVC pipes, avoiding water vapor infiltration and contamination of the floor.

[0052] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
