Said drainage wall with holes is to fill the drainage wall that filtrate forms by the double layer of metal net with between the double layer of metal net.
The drainage wall that said drainage wall with holes is the filtrate concrete spouting.
Described filtrate is that particle size diameter is not less than 2 centimetres building stones.
The beneficial effect of the utility model is: the underground water that the zone of deepening for the part in the building engineering construction process exists; Do not need large tracts of land to reduce underground water; Dewatering installation such as collecting well only is set in the part handles, protected groundwater resources effectively, practiced thrift construction cost.
Below in conjunction with accompanying drawing and embodiment the utility model is done and to be described in further detail.
Description of drawings
Fig. 1 is the utility model collecting well structure chart;
Fig. 2 is the utility model construction sectional structure chart;
Fig. 3 deepens area planar figure for the utility model.
The specific embodiment
The local local ground watering treating apparatus embodiment that deepens in the construction foundation working; Referring to Fig. 1, Fig. 2 and Fig. 3, said device is included in district's 2 settings of underground foundation 1 bottom intensification soil excavation and is no less than a collecting well 3, and collecting well borehole wall 3-1 is a drainage wall with holes; Water pump 4 is set in the collecting well; Water pump water outlet steel pipe 5 extends upward perpendicular to the well head that catchments, and water pump drains into the appointed place through the water outlet steel pipe with water, and water pump is connected through cable 4-1 with power supply; Be provided with well head steel plate for sealing water 6 at the well head that catchments; The water pump water outlet steel pipe that makes progress from the well head steel plate for sealing water is with protection steel pipe 7, and cable penetrates water pump from the protection steel pipe, in underground foundation, is provided with at least one basal layer steel plate for sealing water 8 around the protection steel pipe.
Wherein, said drainage wall with holes is to fill the drainage wall that filtrate forms by the double layer of metal net with between the double layer of metal net.The drainage wall that said drainage wall with holes is the filtrate concrete spouting.
Described filtrate is that particle size diameter is not less than 2 centimetres building stones.
The height of collecting well is greater than the height 500mm of water pump among the embodiment.Said water pump is foul water pump or the clarified water pump that satisfies lift, and steel plate for sealing water is the steel plate of 5 to 10mm thickness.The height of said protection steel pipe is the thickness of concrete foundation layer.
The internal diameter of collecting well described in the present embodiment can satisfy the needs of water pump greater than 400mm.The diameter and the pump outlet of gutter are complementary; The diameter of protection steel pipe is 100mm; The thickness of well head steel plate for sealing water is 5mm, act as waterproof action, and well head steel plate for sealing water diameter is greater than 500mm; Concrete gets into collecting well when preventing that underplate concrete from building, and the hardware described in this instance has all passed through takes antirust processing.
The local concrete application process of deepening the local ground watering treating apparatus is in the present embodiment construction foundation working, and referring to embodiment 1, said method is included in the district's setting of underground foundation bottom intensification soil excavation and is no less than a collecting well; The collecting well borehole wall is a drainage wall with holes; Water pump is set in the collecting well, and the water pump water outlet steel pipe extends upward perpendicular to the well head that catchments, and is provided with the well head steel plate for sealing water at the well head that catchments; Water pump drains into the appointed place through the water outlet steel pipe with water; Water pump is connected through cable with power supply, and the water pump water outlet steel pipe that makes progress from the well head steel plate for sealing water is with the protection steel pipe, in underground foundation, is provided with at least one basal layer steel plate for sealing water around the protection steel pipe; As can beappreciated from fig. 2 groundwater table 10 normally exceeds underground foundation bottom intensification soil excavation district, and its processing method is:
