Abstract
The invention relates to a vacuum tube well precipitation system under geological conditions. Array-type tube wells which are arranged at equal intervals are drilled under foundation pit soil in the route direction, a well point tube is installed in each tube well in an inserted mode, water absorbing holes are formed and distributed along the outer wall of each well point tube, the outer side of each well point tube in the tube well is filled with a material filter layer which is strong in water permeability, a clay layer with the certain thickness is arranged on the upper portion of the material filter layer in each tube well, and a network type water header is arranged in the clay layer in a buried mode, wherein the network type water header is formed by transverse tubes and longitudinal tubes which are communicated with one another; the tube wells are located on the lower portions of the network type junctions of the water header, the end of each transverse tube and the end of the each longitudinal tube are both communicated with the corresponding well point tube in the corresponding tube well, the upper surface of a foundation pit is paved with a concrete layer, the tube opening of each well point tube is exposed outside the concrete layer, and the water head is communicated with a water collecting tank through a centrifugal pump and a vacuum pump. According to the vacuum tube well precipitation system under the geological conditions, the compact degree and the strength of foundation soil are guaranteed, and a reliable guarantee is provided for the safety of follow-up construction.
Description
Technical field
The invention belongs to civil engineering technical field, be specifically related to the vacuum tube well precipitation system under a kind of special geologic condition.
Background technology
When building operations is carried out in some location, due to the reason that ground soil property is loose or underground water is more, even if consolidation is solid again, also can not ensure that foundation strength reaches appointment requirement, this this all had a strong impact on the progress of During Initial Stage Construction engineering, and the safety and reliability of construction to be had a serious impact, therefore geology strengthening is carried out to some geology, solving the problem of ground water drainage, is the very stubborn problem nowadays existed in many fields.
Summary of the invention
Order of the present invention has the vacuum tube well precipitation system be to provide under a kind of special geologic condition.This system can solve the impact of the Groundwater base under ground effectively, makes ground soil property closely knit, increases the intensity of ground.
The technical solution used in the present invention: the vacuum tube well precipitation system under special geologic condition, it comprises header tank, centrifugal pump, vacuum pump, water header and dig the surface level of certain depth and smooth foundation ditch on ground, drill through the pipe well of the matrix-like of the certain arranging rule of spacing along route trend under foundation ditch soil property, a well-point pipe is fitted with in each pipe well, outer wall along well-point pipe is laid with suction hole, the filter material layer that water permeability is strong is filled with outside well-point pipe in pipe well, fill out above filter material layer in pipe well and be provided with certain thickness argillic horizon, be embedded with in argillic horizon be interconnected intersect by transverse pipe and longitudinal pipe the latticed water header formed, it is the position of pipe well below the latticed intersection of water header, and each transverse pipe is all communicated with the well-point pipe in pipe well with the termination of longitudinal pipe, one deck layer of concrete is equipped with at foundation ditch upper surface, the mouth of pipe of well-point pipe is exposed at outside layer of concrete, water header is communicated with header tank with vacuum pump respectively by centrifugal pump.
Further, the diameter of described well-point pipe is 800 millimeters, and the distance bottom the distance pipe well of well-point pipe bottom is 500 millimeters.
Further, described well-point pipe is provided with the suction hole of the certain queueing discipline of spacing on along its length.
The present invention compared with prior art its beneficial effect is: the present invention by laying drainage pipeline networks under ground, after drainage pipeline networks is communicated with negative well, utilize pump groundwater mining to be fallen, ensure that tightness degree and the intensity of ground soil property, the safety for subsequent construction provides reliable guarantee.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
