Specific embodiment
Specific embodiment of the present utility model is described in detail below, it is practical new in order to further understand this
Type.
As shown, a kind of hidden drainage system, comprising: horizontal collection system and vertical flow guide system.Specifically:
Horizontal collection system is made of horizontal collector pipe 1, and vertical flow guide system is made of vertical diversion pipe 3, each component by
Three-way connector 2 is connected.
Specifically, horizontal 1 end of collector pipe terminates in 4 inside of supporting surfacing steel bar net, and each soil layer infiltration collects system by level
System converges through three-way connector 2 to vertical diversion pipe 3 after collecting.Preferably, horizontal collector pipe 1 is the pvc pipe of diameter 50mm.PVC
The tube wall of pipe is provided with the inlet opening of diameter 8mm spacing 100mm.Certainly, the utility model is not limited thereto, art technology
Personnel can select suitable pipe type and size as needed.
That is, horizontal collection system is similar to conventional direct insertion tapping pipe, after foundation pit successively excavates, in branch mask
Pvc pipe, rectangular arrangement, according to the vertical spacing of each soil layer water percolating capacity controlled level collecting pipe and horizontal spacing are inserted into after layer.PVC
Tube wall sets the inlet opening of diameter 8mm spacing 100mm, fills rubble pipe week to guarantee that water flow is unobstructed, wraps up in geotextiles outside to filter
Infiltration avoids line clogging, and end is terminated in 4 inside of supporting surfacing steel bar net, reliably connected using three-way connection and vertical diversion pipe
It connects, each soil layer infiltration is unified after being collected by horizontal collection system to converge to vertical diversion pipe.
Specifically, vertical diversion pipe 3 is along the 4 elongated setting in inside of supporting surfacing steel bar net.Vertical diversion pipe 3 is along foundation pit side-wall
Bottom of foundation ditch is extended to, in bottom of foundation ditch by being pierced by branch armour layer, charge for remittance in pipe is expelled to the intercepting ditch 5 of bottom of foundation ditch.It is perpendicular
The pvc pipe or soft water-permeable pipe for being diameter 50mm to diversion pipe 3.Certainly, the utility model is not limited thereto, art technology
Personnel can select suitable pipe type and size as needed.
That is, the elongated setting on the inside of supporting surfacing steel bar net of vertical diversion pipe, by first of horizontal collecting pipe
Begin, foundation pit bottom is extended to along foundation pit side-wall, using three-way connector (three-way connection), by all levels in same vertical plane
Collecting pipe is connected, and forms one group of complete drainage channel in bottom of foundation ditch by being pierced by branch armour layer and charge for remittance in pipe is expelled to base
Bottom intercepting ditch is cheated, the hole bright heat-extraction system in bottom is thus imported.Vertical diversion pipe is not necessarily to once mounting in place, with the layering of the earthwork
Excavation is installed section by section according to the spacing of horizontal collecting pipe, and each section is reliably connected with finer wire and retaining wall steel mesh perpendicular to guarantee
It is not shifted to diversion pipe when branch armour layer carries out concrete ejection, is indeformable.Should be noted while installation vertical diversion pipe away from
Clear distance from steel mesh meets dado thickness design requirement, forms structural weak point after avoiding dado thickness from being weakened, is unfavorable for
The safety of foundation pit.
In drainage system construction and use process, vertical water conservancy diversion pipe end should be made to be placed in always, concrete ejection is completed
Branch armour layer lower end, to guarantee its drainability in the construction process, while answering the vertical diversion pipe nozzle of running check, with
Blocking is excluded, keeps draining unobstructed.
Cubic metre of earth every excavation certain depth, in the soil body on the inside of horizontal collector pipe insertion branch armour layer, will fill in pipe week rubble with
Guarantee that water flow is unobstructed, wraps up in geotextiles outside to avoid line clogging, controlling length makes horizontal tube end of collecting terminate in branch armour layer steel
On the inside of muscle net, it is reliably connected followed by three-way connection and vertical diversion pipe.
The elongated setting on the inside of supporting surfacing steel bar net of vertical diversion pipe, but in place without once mounting, with the earthwork
Stage excavation installed section by section according to the spacing of horizontal collecting pipe, complete this layer sewerage system installation after carry out foundation pit retaining wall reinforcing bar
Rack is set, then is reliably connected the vertical diversion pipe of each section with retaining wall steel mesh with finer wire, to guarantee that vertical diversion pipe is propping up
Armour layer do not shift when concrete ejection, is indeformable.Installation is originated by first of horizontal collecting pipe, layer-by-layer along foundation pit side-wall
To foundation pit bottom, tube bottom end penetrates branch armour layer and stretches out certain length for installation, and charge for remittance is imported the hole bright heat-extraction system in bottom.In installation process
It need to guarantee that vertical water conservancy diversion bottom of the tube is always positioned at concrete ejection finished surface or less to guarantee the drain function in work progress.
Hidden drainaging scheme is suitable for the base pit engineering of campshed supporting, which advantageously ensures that branch armour layer
Stability, improves the safety of entire base pit engineering, while providing for the construction of subsequent outsourcing waterproofing work dry, clean
Working face.
Although the utility model is disclosed as above with embodiment, so it is not intended to limit the utility model, any ability
Field technique personnel can make a variety of different selections and modification, therefore this without departing from the spirit and scope of the utility model
The protection scope of utility model is limited by claims and its equivalents.
