Description
Technical field
The utility model relates to a kind of drainage of foundation pit device, the device of particularly a kind of open-cut foundation ditch draining.
Background technology
Various drainage of foundation pit work is a very important job in high-building construction; in city underground open-cut station construction of bottom plates; groundwater table is higher; well-points dewatering is unconditionally done by nearby residents district; and well-points dewatering need be constructed for 1 month before soil excavation; precipitation need last till that station base plate is completely closed, and pumping cycle is long, is unfavorable for protection of groundwater resource.
Conventional well point dewatering is strict to site requirements, in the construction plant that residential building stands in great numbers, because place restriction does not reach the requirement of totally-enclosed layout, excavation sump is often taked to draw water bright row's scheme, the scheme of this bright row that draws water easily is caved at layer of sand excavation, cause excavation area large, substrate undisturbed soil is destroyed large, affect substrate earth bearing strength; Not only efficiency of construction is low, and construction effect is poor, and can not control excavation area, can not recycle, very large on workmanship impact.
Utility model content
The purpose of this utility model is to provide a kind of open-cut foundation ditch dewatering installation, solve drainage of foundation pit and destroy base large, the technical problem that excavation area is large; And solve that dewatering installation can recycle, cost-saving problem.
For achieving the above object, the utility model adopts following technical scheme:
A kind of open-cut foundation ditch dewatering installation, the filtrate comprising collecting well, the gutter be communicated with collecting well and be arranged on around gutter, the side of the forward construction section of a construction section after this device is positioned over, described collecting well Lower Half is a cubical water tank, water pump is provided with in water tank, be connected with one directly over water tank and vertically disposedly hang mouth, described middle part of hanging mouthful periphery is provided with a water proof steel plate, the side of described water tank is connected with the gutter having some drain holes, and described gutter is wrapped with one deck filter screen.
Described gutter is the iron pipe of φ 150mm, and iron pipe pipe shaft has the hole of several 1-2cm.
Described filtrate is backfill cobble or sandstone.
Compared with prior art the utility model has following characteristics and beneficial effect:
The utility model is applicable to city underground open-cut station construction of bottom plates, and groundwater table is higher, and well-points dewatering is unconditionally done by nearby residents district, can carry out water-pumping/draining being excavated to absolute altitude near floor.Namely adopt and brightly drain into dewatering installation, then pump drainage is to appointed place.Can effectively control excavation area at 1500*1500*1500, compare Normal practice escapable cost, protection groundwater resources, construction method is simple, efficiency is high, time and labour saving, and can reuse.
The pipe shaft of gutter of the present utility model has some holes, and outside is tied with filter screen again, can effectively prevent fine sand between stake to run off.Dewatering installation is laid all in foundation ditch, can not take the foundation ditch external space, dramatically saves on construction space, due to without the need to carrying out dewatering well construction, can reduce construction cost, using method is simple, efficiency is high, time and labour saving, and can recycle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is work progress schematic diagram of the present utility model.
Reference numeral: 1-collecting well, 2-water tank, 3-hang a construction section after mouth, 4-water pump, 5-water proof steel plate, 6-gutter, 7-filtrate, 8-filter screen, 9-drain hole, the last construction section of 10-, 11-.
Detailed description of the invention
Embodiment is see shown in Fig. 1 and Fig. 2, and the arrow in Fig. 1 is water (flow) direction.This open-cut foundation ditch dewatering installation, the filtrate 7 comprising collecting well 1, the gutter 6 be communicated with collecting well and be arranged on around gutter, the side of the forward construction section 10 of a construction section 11 after this device is positioned over, described collecting well Lower Half is a cubical water tank 2, water pump 4 is provided with in water tank 2, be connected with one directly over water tank 2 and vertically disposedly hang mouth 3, described middle part of hanging mouthful periphery is provided with a water proof steel plate 5, the side of described water tank is connected with the gutter 6 having some drain holes 9, and described gutter 6 is wrapped with one deck filter screen 8.
Described gutter 6 is the iron pipe of φ 150mm, and iron pipe pipe shaft has the hole of several 1-2cm.The outside of hole is tied with filter screen again, can effectively prevent fine sand between stake to run off.Described filtrate 7 is backfill cobble or sandstone.
The size of collecting well of the present utility model and the flow of water pump are determined according to on-the-spot actual requirement, according to the water yield of foundation ditch, calculate the flow of water pump in the capacity of this device and collecting well, ensure that a upper construction section water level is below water proof steel plate.According to the division of station construction section, be guided to by last construction section underground water in the collecting well of a rear construction section, start the water pump in collecting well, in pump drainage collecting well, water is to appointed place.
Course of work step of the present utility model is as follows: according to the division of station construction section, step 1: be guided to by last construction section underground water in the collecting well of a rear construction section; Step 2: start the water pump in collecting well, in pump drainage collecting well, water is to appointed place; Step 3: lay Polypropylence Sheet at last construction section, 10cm waterproof of constructing successively bed course, then do the thick pea gravel concreten of 5cm and do fish tail and waterproof layer; Step 4: colligation baseplate reinforcing bar, construction underplate concrete; Step 5: the construction repeating step 1-4, to final stage construction section, at baseplate reinforcing bar, the place of punching performs stiffener, and performs concrete, step 6: reserved opening, hangs out unnecessary water pump; Step 7: seal with water proof Plate Welding and fill up opening with the concrete higher than a base plate label.
