Abstract
The utility model relates to the technical field of engineering elevators, in particular to a bearing platform water stopping structure capable of being applied to an elevator. The bearing platform water stopping structure comprises a foundation pit and a water-collecting well arranged under the foundation pit. A secondary pouring part is arranged in the foundation pit, and the secondary pouring part and the water-collecting well are communicated through a pipeline. The pipeline is arranged in the foundation pit, penetrates through the secondary pouring part and stretches into the water-collecting well. In the bearing platform water stopping structure capable of being applied to the elevator, the secondary pouring part is arranged in the foundation pit, and the pipeline is arranged to enable the secondary pouring part to be communicated with the water-colleting well. The method of secondary pouring water outlet is adopted, so that water stopping effect of a bearing platform is achieved and the quality of a base plate concrete is guaranteed.

Preferably, described isolation layer is comprised of Polypropylence Sheet and glass-fiber-fabric.
Preferably, described bed course is concrete cushion.
Three of improvement is provided with water pumper in the described collecting well, and water pumper is connected with described pipeline.
Preferably, described water pumper comprises feed pump and reserve pump.
Four of improvement, described collecting well and secondary are built and are provided with stock mould between the position.
Five of improvement, the part that described pipeline is built in the position at secondary is provided with valve.
Compared with prior art, the beneficial effects of the utility model are:
The utility model can be used for the cushion cap water-stopping structure at elevator position, is provided with secondary and builds the position in foundation ditch, and be provided with pipeline it is communicated with collecting well, and the method that adopts secondary to build delivery port reaches the effect of cushion cap sealing, has guaranteed the quality of bottom board concrete.
Description of drawings
Fig. 1 is the schematic diagram of the utility model cushion cap water-stopping structure.
The specific embodiment
Below in conjunction with the Concrete facts mode the utility model is further described.
Be illustrated in figure 1 as the embodiment of the utility model cushion cap water-stopping structure, comprise foundation ditch 10 and be located at collecting well 20 under the foundation ditch 10, be provided with secondary in the foundation ditch 10 and build position 30, secondary is built between position 30 and the collecting well 20 and is communicated with by pipeline 40, pipeline 40 is located in the foundation ditch 10, and it passes secondary and builds position 30 and stretch in the collecting well 20; Foundation ditch 10 bottom surfaces are provided with drainage layer 101, and drainage layer 101 is provided with bed course 102, are provided with isolation layer 103 between drainage layer 101 and the bed course 102; Bed course 102 is provided with well head 104 at collecting well 20 positions, and well head 104 is provided with prefabricated cover plate 105; Be provided with water pumper 201 in the collecting well 20, water pumper 201 is connected with pipeline 40; Collecting well 20 and secondary are built and are provided with stock mould 106 between the position 30, and the part that pipeline 40 is built in the position 30 at secondary is provided with valve 401.Wherein, isolation layer 103 is comprised of Polypropylence Sheet and glass-fiber-fabric; Bed course 102 is concrete cushion; Water pumper 201 comprises feed pump 202 and reserve pump 203.
During practice of construction, in foundation ditch 10 bottoms with the method excavated by manual work collecting well 20 of brick open caisson, about collecting well 20 degree of depth 2m, simultaneously at two water pumpers 201 of collecting well 20 interior layouts, i.e. a feed pump 202 and a reserve pump 203, and shop, the bottom surface in elevator foundation ditch 10 rubble drainage layer 101, the water burst of the end, hole, hole wall can be converged in collecting well 20; Lay the isolation layer 103 that Polypropylence Sheet and glass-fiber-fabric form on rubble drainage layer 101, build foundation pad 102 at isolation layer 103, bed course 102 is reserved well head 104 at collecting well 20 positions; Make prefabricated cover plate 105 at well head 104, pipeline 40 passes cover plate, forms the individual pressure reduction well that catchments.Water pumper 201 constantly draws water and makes foundation ditch 10 inside without ponding during reinforcing bar binding.
Present embodiment passes the cushion cap position at pipeline 40 the measure sealing that secondary is built position 30 is set.When building bottom board concrete, do a 1m * 1m * 1.2m stock mould 106 with the 3mm steel plate, pipeline 40 passes stock mould 106, a valve 401 is installed on the pipeline 40 in the stock mould 106, stock mould 106 interior concretes are done secondary and are built, water pumper 201 constantly draws water when watering bottom board concrete, make groundwater table at bed course below 102, stock mould 106 interior concretes are not built, until bottom board concrete build finish maintenance a period of time after, stop pumping, valve-off 401, the water pipe of valve more than 401 cuts away sealing, the C45 expansive concrete that is higher than the bottom board concrete one-level in stock mould 106 interior usefulness is built stock mould 106 interior concretes, aqueduct valve 401 is cast in the bottom board concrete, thereby improves self waterproof ability of concrete.
