Description
Technical field
The invention belongs to construction technology in geotechnical engineering field, more particularly, to a kind of novel plastic as water-stop curtain every
Water plate.
Background technology
In Supporting Structure of Deep Foundation Pit in City, to be often related to foundation ditch waterproof, patching, these processing are usually required only
Water curtain.Water-stop curtain has a variety of patterns, such as using plain concrete (clay) and armored concrete interlocking pile, reinforced concrete pile
Between add high pressure rotary churning pile, continuous deep stir stake, continuous high-pressure rotary jet grouting pile etc..And water-stop curtain or stake in Composition Soil Nailing Walls
In the single water-stop curtain engineering separated with water-stop curtain wall, piling wall is usually stirred or single high-pressure rotary-spray piling wall using single depth
It is used as water-stop curtain.In these water-stop curtains, although water proof effect preferably, but there is also curtain curtain depth requirements compared with
Deep (being more than 16 meters) or soil layer deep have rubble, cementing piece, closely knit sandy gravel stratum and stir deeply during with complex situations such as underground water
Piling wall is mixed to be difficult to reach that sealing purpose or water-stop curtain have the problem of cost is higher.
Accordingly, it would be desirable to which one kind can effectively control cost and can be in curtain depth requirements relatively depth or soil layer deep
The complicated area of situation carries out the foundation ditch waterproof of deep foundation pit support, the water-stop curtain of patching.
The content of the invention
The purpose of the present invention, exactly to overcome the defect that above-mentioned prior art is present, there is provided as the new of water-stop curtain
Plastics water-stop sheet.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of plastics water-stop sheet for making water-stop curtain for foundation pit side-wall, it is characterised in that the water-stop sheet is main by buffering
Layer, constituted using high molecular polymer as the splash guard of raw material, metallic plate etc..Cushion is close to foundation pit side-wall or primary supporting, gold
Belong to plate close to foundation pit enclosure structures such as diaphram walls, splash guard is located between cushion and metallic plate, and three uses thermal weld
Connection.
First after deep pit digging, primary supporting is carried out, certain fill out is reserved between primary supporting and underground campshed
Native space, treats to use board-plugging device insert continually after the completion of piling structure, rather than (water-stop sheet of the present invention includes buffering using drain bar
Layer, using high molecular polymer as the splash guard of raw material, metallic plate).The water-stop curtain that water-stop sheet of the present invention is constituted replaces ability
The existing mixing pile in domain does lateral water-stop curtain.After the completion of carry out construction elsewhere and draining again.
By interface and the dual connection of binding agent between plastics water-stop sheet, to ensure the impermeability between two water-stop sheets.
Using tenon structure connection between cushion and cushion, between metal level and metal level, used between splash guard and splash guard
Binding agent is connected.The intensity of structure had so both been ensure that, the stability and sealing of structure is in turn ensure that.
Splash guard in described plastics water-stop sheet is made up of high molecular polymer for raw material, can select ethene-acetic acid second
Alkene copolymer, ethene-pitch polymer blend, polyvinyl chloride, the material of high-density polyethylene alkenes or other similar natures, should
With good puncture resistance, durability, water resistance, corrosion resistance, fungus resistance, thickness is 2-4mm.
Filtering layer is made in cushion in described plastics water-stop sheet, two sides with non-woven geotextile parcel, and core ribbon uses nothing
Cloth and polyethylene foams composition, connection preliminary bracing structure and splash guard are spun, as a buffering, is played a protective role.
For buffer preliminary bracing basal plane be uneven or burr wears out drainage systems, thickness 5-7mm.
Described metallic plate plays an adjection, thickness 8-10mm to waterproof layer mainly as the support of structure.
With it is existing continuously stir stake (cement mixing method etc.), single tube, three pipe rotary churning piles formation sealing wall technology compared with,
The present invention can it is more reliable, be easily used for foundation pit side-wall, the impermeable role in tunnel, cost is low, the preferable advantage of water-stagnating effect.
Compared with prior art, the present invention has advantages below：
1st, using the board-plugging device using plastic draining board in basement process, insert continually water-stop sheet rather than drain bar.Generation
Lateral water-stop curtain is done for mixing pile, is suitable for deeper soft clay area.
2nd, using cushion, splash guard, metal layer combination formula structure, with puncture resistance, durability, water resistance, sealing
Effect is preferable.
3rd, constructed using board-plugging device, simple to operate, cost is low.
