Abstract
The utility model relates to an internal-supporting type deep foundation pit latticed column well-point rainfall system which comprises a latticed column supporting pile hole, a peastone filtering layer, a steel wire gauze, a steel latticed column, a sinking pump and a water draining pipe. The steel wire gauze wraps the outer surface of the steel latticed column, is fixed on the outer surface of the steel latticed column, and is placed in the latticed column supporting pile hole of pouring concrete along with the steel latticed column, peastone is filled in a gap between the steel wire gauze and the latticed column supporting pile hole to form the peastone filtering layer, and the sinking pump is suspended into the bottom of a precipitation well and is connected with the water draining pipe. An original steel latticed column and an original steel latticed column supporting pile hole in the internal-supporting type foundation pit supporting engineer are fully utilized by the internal-supporting type deep foundation pit latticed column well-point rainfall system, the deep foundation pit precipitation well is formed by the fact that the steel wire gauze wraps the outer side of the steel latticed column, the peastone filtering layer is filled between the steel wire gauze and the latticed column supporting pile hole, underground water in a foundation pit can be continuously drained through the water draining pie and the sinking pump placed at the bottom of the well, the moisture content of the earthwork in the foundation pit can be effectively, and earthwork excavation efficiency and earthwork transport efficiency are improved.
Description
Technical field
The utility model belongs to technical field of building construction, is specifically related to a kind of inner supporting type deep foundation ditch lattice column well-points dewatering system.
Background technology
The construction work deep foundation ditch for guaranteeing the efficient of soil excavation, transportation, need take dewatering measure to reduce groundwater table in the foundation ditch, so that the moisture content of institute's earth excavation remains on a lower level in the soil excavation process.Traditional well-points dewatering method cost is higher and precipitation efficiency is on the low side, also needs to arrange specially several precipitation well in foundation pit, has caused a lot of inconvenience for the soil excavation process.
Summary of the invention
The utility model can't be comparatively economically in digging process in order to solve the construction work deep foundation ditch, the problem of precipitation effectively, and provide a kind of inner supporting type deep foundation ditch lattice column well-points dewatering system, the utility model takes full advantage of original steel lattice column in the inner supporting type foundation pit supporting project, steel lattice column supporting pile stake hole, by at steel lattice column outer wrapping gauze wire cloth, between gauze wire cloth and supporting pile hole hole wall, fill the Guamishi filtration beds and form a deep foundation pit precipitation well, by gutter and the submersible pump that is placed on the shaft bottom underground water in the foundation ditch is continued to discharge, effectively reduce the moisture content of the earthwork in the foundation ditch, improve soil excavation, conevying efficiency.
The technical solution of the utility model is:
Inner supporting type deep foundation ditch lattice column well-points dewatering system, comprise lattice column supporting pile stake hole, Guamishi filtration beds, gauze wire cloth, steel lattice column, submersible pump and gutter, it is characterized in that: the gauze wire cloth parcel also is fixed in the steel lattice column external surface, and put into the lattice column supporting pile stake hole of concreting with steel lattice column, Guamishi is filled in the space between gauze wire cloth and the lattice column supporting pile stake hole and forms the Guamishi filtration beds; Submersible pump hangs in the shaft bottom of precipitation well, and connects gutter.
The utility model takes full advantage of original steel lattice column in the inner supporting type foundation pit supporting project, lattice column supporting pile stake hole, form a deep foundation pit precipitation well by fill the Guamishi filtration beds at steel lattice column outer wrapping gauze wire cloth, between gauze wire cloth and lattice column supporting pile stake hole, by gutter and the submersible pump that is placed on the shaft bottom underground water in the foundation ditch is continued to discharge.
The utlity model has characteristics reasonable in design, easy to operate, that cost is low, precipitation efficiency is high, the inner supporting type deep foundation ditch lattice column well-points dewatering system that the utility model provides can reduce the groundwater table in the foundation ditch effectively, reduce the water content of the earthwork in the foundation ditch, avoid occurring in the soil excavation process situation of large tracts of land mud, improve soil excavation, conevying efficiency effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1 and Figure 2, the utility model comprises lattice column supporting pile stake hole 1, Guamishi filtration beds 2, gauze wire cloth 3, steel lattice column 4, submersible pump 5 and gutter 6, it is characterized in that: gauze wire cloth 3 parcels also are fixed in steel lattice column 4 external surfaces, and put into the lattice column supporting pile stake hole 1 of concreting with steel lattice column 4, Guamishi is filled in the space between gauze wire cloth 3 and the lattice column supporting pile stake hole 1 and forms Guamishi filtration beds 2; Submersible pump 5 hangs in the shaft bottom of precipitation well, and connects gutter 6.
Size, the specification of lattice column supporting pile stake hole, steel lattice column are all constructed according to the foundation pit supporting project design drawing.The specification of Guamishi is identical with the specification of the aggregate-Guamishi of the desired pea gravel concreten of Structural Engineering design drawing, its effect is to form borehole wall outside filtration beds, filter containing mud underground water, silt stops up precipitation well, submersible pump and gutter in the anti-sealing.The specification of gauze wire cloth is identical with the specification that the desired late poured band of Structural Engineering design drawing is cut off gauze wire cloth, and its effect is to prevent that Guamishi from falling in the steel lattice column, in order to avoid stop up the precipitation well, and carry out secondary filter to containing mud underground water.
The specification of submersible pump, gutter, model are determined according to size and the precipitation efficiency of aperture, steel latticework stanchion hole, stake hole depth, steel lattice column headroom size, amount of precipitation.
In the engineering construction process, with gauze wire cloth parcel and be fixed in the steel lattice column external surface, and put into lattice column supporting pile stake hole with steel lattice column, after lattice column bottom support pile concrete is built and is finished, Guamishi is poured in the space between gauze wire cloth and the lattice column supporting pile stake hole, form the Guamishi filtration beds, so far, inner supporting type deep foundation ditch lattice column precipitation well is arranged and is finished.Submersible pump is hung in the shaft bottom of precipitation well, can carry out well-points dewatering to deep foundation ditch after connecting gutter, native system can reduce the groundwater table in the foundation ditch effectively, reduce the water content of the earthwork in the foundation ditch, avoid occurring in the soil excavation process situation of large tracts of land mud, improve soil excavation, conevying efficiency effectively.
