Background technology
With a large amount of constructions and the utilization of the underground space of skyscraper, base pit engineering is also more and more, ground and base
It can be influenced by underground water in plinth construction, Yield rainfall relation is always a great problem for perplexing construction, there is diving in soil mass of foundation pit,
Surface water also flows into foundation pit.
In traditional handicraft, frequently with bright row or the well-points dewatering technique of catchmenting, bright row's mode of catchmenting can only be solved compared with shallow foundation
Yield rainfall relation is cheated, and easily causes quicksand inside foundation pit.Well-points dewatering is that well-point pipe is buried around foundation pit, and laying is catchmented total
Pipe, is promoted to ground by underground water by pumping equipment and drains, and achievees the purpose that reduce water level, but well-points dewatering needs are longer
Cycle in precipitation and larger management of equipment maintenance input.
Chinese invention patent application CN106498961A disclose a kind of Yield rainfall relation system equipped with detachable header tank and
Its Yield rainfall relation method comprising dewatering well.Header tank group comprising unidirectional header tank, two-way straight-through header tank, two-way corner collection
Water tank, three-dimensional header tank and four-way header tank.Unidirectional header tank, two-way straight-through header tank, two-way corner header tank, three-dimensional are catchmented
Case and four-way header tank form a uncovered babinet knot including bottom plate and the tubular plate being fixed on bottom plate, bottom plate and tubular plate
Structure.The mouthpiece for being equipped with hole on tubular plate and being arranged on hole.Discharge pipe line is detachably connected on mouthpiece；
Precipitation pipeline, one end are located in header tank group any one header tank, and the other end is located in dewatering well, and precipitation pipeline is located at drop
The end of one end in well is equipped with water pump.The patent application stresses the header tank detachably reused, the steel plate of use,
It can theoretically recycle, but in fact, when doing subdrainage because place is small, if to realize detachably, need to drain
Pipe digs up, and cost higher instead might as well do well-points dewatering, practicability is not strong for the technical staff in industry.
Utility model content
The utility model is intended to provide a kind of simple Yield rainfall relation device, simple and reasonable, the making of the Yield rainfall relation device
It is convenient, at low cost, and water level can be effectively reduced in construction.
To achieve the goals above, technical solution used by the utility model is：
A kind of simple Yield rainfall relation device, including multiple vertically arranged dewatering wells pass through row between two neighboring dewatering well
Water pipe is connected to；It is structurally characterized in that, multiple drain holes are provided on the side wall of the dewatering well, is wrapped in dewatering well permeable
Layer；The tube wall top of the drainpipe of whole lateral arrangement offers multiple drain holes, and pervious bed is wrapped in drainpipe.
Embodiment according to the present utility model can also make the utility model further optimization, below for optimization after
The technical solution of formation：
In order to play the effect of coarse filtration, filter layer is provided with above the drainpipe.Further, the filter layer
For metalling.It can be effectively prevented mud in this way and block pervious bed.
Preferably, the pervious bed is grid nylon cloth.Thin lattice nylon cloth can obstruct fine sand and clay as a result, after being not required to
Phase maintenance cost, reduces labor intensity.
Preferably, the dewatering well is the concrete downcomer on the basis of being located at pipe well；The concrete downcomer
Caliber is 1m-2m.
In order to facilitate laying, the drainpipe is HDPE（High density polyethylene (HDPE)）Hollow spiral tube；The drainpipe
Caliber is 0.2m-0.5m.
In order to facilitate the low formation slope surface in the high both ends in stage casing of drainpipe described in water.
Preferably, the slope surface gradient of the drainpipe is 1-3%.
Preferably, the caliber of the dewatering well is more than the caliber of drainpipe；The aperture of the drain hole of the dewatering well is more than
The aperture of the drain hole of drainpipe.
Preferably, the bottom of the dewatering well is connected by pipeline with water pump.Thus underground water flows to precipitation along drainpipe
After well, it is discharged by water pump.
Compared with prior art, the utility model has the beneficial effects that：
The Yield rainfall relation device of the utility model flows into dewatering well using underground water by drainpipe drain hole, around drainpipe
Permeable thin lattice nylon cloth, fine sand and clay can be obstructed, later maintenance expense is not required to, reduces labor intensity.
The drain pipe diameter of the utility model is small, is not influenced on the structure of foundation pit.
It is utility model device combination advantages of simple, easy to make, water level can be effectively reduced in construction.
Description of the drawings
Fig. 1 is the structure principle chart of the utility model one embodiment；
Fig. 2 is A-A sectional views of Fig. 1.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the feature in the embodiments of the present invention and embodiment can be combined with each other.For sake of convenience, hereinafter such as
There are "upper", "lower", "left", "right" printed words, only indicates consistent with the upper and lower, left and right direction of attached drawing itself, not to structure
