Description
Technical field
The present invention relates to retaining wall field, specifically hydraulic engineering with have anti-filter mechanism retaining wall device and
Construction method.
Background technology
Retaining wall refers to support Roadbed Soil or the hillside soil body, prevent from banketing or the structure of soil deformation unstability.At gear
In cob wall transverse section, it is referred to as the wall back of the body with being supported by the position that the soil body directly contacts；Relative with the wall back of the body, to face sky position is referred to as wall
Face；The position directly contacted with ground is referred to as substrate；End face relative with substrate, wall is referred to as wall top；The front end of substrate is referred to as
Toe of wall；The rear end of substrate is referred to as wall heel.Retaining wall is widely used in the engineering constructions such as water conservancy, traffic, harbour and work China Democratic National Construction Association, its
Purpose is barricade back of the body backfill soil or a hillside soil body, prevents soil deformation unstability.
When hydrops carried on the back by wall, the water level after retaining walls is higher and water level of before wall is relatively low or anhydrous time, add again hydraulic pressure
Power, easily causes retaining wall and collapses.In order to hydrops is prone to discharge after making wall, generally arrange an appropriate number of sluicing at wall body
Hole.But grogs can enter spilled water hole along with infiltration, thus cause spilled water hole to block, along with the increasing of hydrops after wall, can reduce
The safety coefficient of barricade, particularly after heavy rain, frequently can lead to collapsing of cutting barricade.

Having anti-filter mechanism, anti-filter mechanism to include geotextiles 3 and the anti-filter bed of material, geotextiles 3 is fixed on the entrance of drain pipe 2, filter material
Layer is wrapped in geotextiles 3.
Wherein, the anti-filter bed of material includes that granule layer 5 and middle gravel bed 4, granule layer 5 and middle gravel bed 4 are mainly by basic unit, middle level
With the Contraband character form structure of upper strata composition, the entrance of drain pipe 2 is positioned at the opening of granule layer 5, and granule layer 5 is filled in middle gravel bed 4
Opening in；Near the medial surface that side is the anti-filter bed of material of body of wall 1 on the anti-filter bed of material, relative with medial surface on the anti-filter bed of material
Side is the lateral surface of the anti-filter bed of material, and geotextiles 3 is wrapped in the medial surface of the anti-filter bed of material, the bottom surface of the anti-filter bed of material, the anti-filter bed of material
Lateral surface and the anti-filter bed of material end face on.Wherein, the diameter of middle gravel bed 4 cobble-stone is about 15mm, and its minimum grain size is not
Less than 5mm, its maximum particle diameter cannot be greater than 20mm, and clay content cannot be greater than 5%, and without the impurity such as grass roots, rubbish；Granule layer 5
The diameter of cobble-stone is about 3mm, and its minimum grain size is not less than 2mm, and its maximum particle diameter cannot be greater than 5mm, and without grass roots, rubbish
The impurity such as rubbish, its clay content cannot be greater than 5%；Geotextiles 3 for thickness be 3.5mm, weight be the geotextiles 3 of every square metre of 400g.
Being wrapped in the part on the medial surface of the anti-filter bed of material in geotextiles 3 is closure part, in geotextiles 3 in addition to closure part
Part is outsourcing portion, and the top of closure part is fixed on body of wall 1 by polyester ammonia glue layer and is positioned at the top of drain pipe 2, envelope
Stifled solid middle part is fixed on the entrance of drain pipe 2 by polyester ammonia glue layer, and polyester ammonia glue layer is passed through in the bottom of closure part
It is fixed on body of wall 1 and is positioned at the lower section of drain pipe 2；Near the medial surface that side is middle gravel bed 4 of body of wall 1 on middle gravel bed 4, in
Side relative with medial surface on gravel bed 4 is middle gravel bed 4 lateral surface, and outsourcing portion is wrapped in outside the bottom surface of middle gravel bed 4, middle gravel bed 4
On side and middle gravel bed 4 end face.
Near body of wall 1 and be positioned at the upper end that the end above drain pipe 2 is outsourcing portion, the upper end in outsourcing portion in outsourcing portion
Portion is fixed on body of wall 1 by polyester ammonia glue layer.
The hydraulic engineering of the present invention retaining wall device with anti-filter mechanism, can be used for both sides, river course, each retaining wall
Height about between 5.6m and 8.6m, the top width 0.5m of each retaining wall, bottom width are between 7.5m to 8.3m, at retaining wall
The i.e. retaining wall of wall dorsal part side, the back of the body river backfill backfill soil 6, backfill soil 6 height be 87.6 meters.The wall dorsal part of body of wall 1 a large amount of
Hydrops can be discharged by drain pipe 2 after anti-filter mechanism filters.Particularly as follows: when hydrops flows to drain pipe 2, on geotextiles 3 surface,
First thicker grogs is trapped, and forms coarse grain layer, and water penetration increases；Meanwhile, this fraction of coarser layer will stop behind thin
Grogs continues to be taken away by current, and more toward wall dorsal part direction, the probability that fine soil grain is run off is the least, just in geotextiles 3
Wall dorsal part forms a granule tapered " natural loaded filter "；Part passes through seepage flow through the tiny soil particle of geotextiles 3
Entering granule layer 5, middle gravel bed 4, osmotic resistance reduces, and flow velocity is accelerated, and relatively coarse granule continues to be trapped, and is attached to granule layer 5 and stitches
Gap, along with the change in filtering layer space is big, seepage flow is also accelerated, and then plays draining, filter soil, the effect of decompression.
This hydraulic engineering retaining wall device with anti-filter mechanism has good economic benefit, has saved engineering and open
, mainly show as the following aspects:
(1), practical, construction technology is simple, construction cost is low；
(2), multiple drain pipe 2 is set in retaining wall, anti-filter mechanism is set in the porch of each drain pipe 2, can arrange in time
Except infiltration filter is native, reduce consolidation pressure, prevent surface collapse, increase the safety and stability of body of wall 1；
(3), can suitably reduce retaining wall own wt, reduce concrete amount, save engineering cost, under effect of water pressure,
6.6 meters high retaining wall unit lengths increase stress 43.12KN, can reduce water pressure pair after arranging multiple drain pipe 2 in body of wall 1
The effect of retaining wall, and then retaining wall deadweight can be reduced, reducing concrete amount, retaining wall unit length can reduce concrete and use
Measuring 0.67 cubic metre, concrete every cube cost 300 yuan/cubic metre, unit length retaining wall can save expense 201 yuan, gear soil
During wall length 660 meters, expense 132660 yuan can be saved.
