Abstract
The utility model provides a water-proof curtain, which comprises sleeve pouring piles arranged along a foundation pit wall at intervals and rotating spray piles which are arranged between two adjacent sleeve pouring piles and meshed with the sleeve pouring piles, the water-proof curtain is formed by meshing the sleeve pouring piles with the rotating spray piles on the outer side of the foundation pit wall, and the water-proof performance of the rotating spray piles and the bending resistance of the sleeve pouring piles are fully utilized. The water-proof curtain can perform wall body full length seamless construction, effectively solve the problems of water seepage, water leakage, sand flow and the like of a foundation pit, and effectively overcome the common quality shortcomings of slumping holes, necking and the like of other type punching pouring piles. The water-proof curtain adopts a full sleeve driller to drill holes to form the piles, peripheral soil body structures can not be damaged during earthwork evacuating process, operation is safe, the construction process has no slurry pollution, and reinforced concrete piles formed by pouring are regular and uniform. Compared with traditional drilling hole piles, piles in row or a underground successive wall technology, the water-proof curtain is smaller in earthwork evacuation quantity and small in influence on and constructional pollution to the peripheral environment.
Description
Technical field
The utility model relates to the realm of building construction, relates in particular to a kind of water-stop curtain.
Background technology
Along with developing rapidly of China's construction market, the emerge in multitude of high level and super highrise building is in the high area of groundwater table, near filling out Haiti district, alluvial delta area, the regional deep-foundation pit engineering ubiquity of complicated geological condition such as mud or drift sand being arranged.For realizing the sealing purpose of deep foundation ditch, prior art provides multiple water-stop curtain to comprise diaphragm wall, drill-pouring interlock stake and sleeve pipe perfusion interlock stake etc.Wherein more general diaphragm wall and perfusion interlock stake; And cost is lower and be the water-stop curtain that the mutual interlock of sleeve filling pile forms to lower a kind of of ambient influnence; Its sealing principle mainly is to form second sleeve filling pile at the middle concrete perfusion once more of adjacent two first sleeve filling piles that construct previous stage, and supporting and sealing are carried out in the mutual interlock formation of first sleeve filling pile and second sleeve filling pile " piling wall ".
Because second sleeve filling pile must be accomplished construction before concrete final set; This requires very high to concrete ultra retarding performance; In case cause surpassing slow setting stake final setting time because of plant equipment breaks down; To make first sleeve filling pile and second sleeve filling pile can't form occluding relation, even can't construct, directly have influence on the waterproof between piles effect.
The utility model content
The utility model embodiment technical problem to be solved is, a kind of water-stop curtain is provided, and infiltration occurs, leaks and the drift sand phenomenon to prevent foundation ditch, guarantees construction high efficiency and low cost.
In order to solve the problems of the technologies described above, the utility model embodiment has proposed a kind of water-stop curtain, comprises the sleeve filling pile that keeps at a certain distance away and be provided with along foundation pit walls, and is arranged between adjacent two sleeve filling piles and the rotary churning pile of interlock with it.
Further, said sleeve filling pile and rotary churning pile stake top is provided with Guan Liang.
Further, the length of said sleeve filling pile and rotary churning pile is 13-16m.
The utility model embodiment forms water-stop curtain through be engaged in the foundation pit walls outside by sleeve filling pile and rotary churning pile, has following beneficial effect:
1, can effectively prevent problems such as foundation ditch occurs seep water, leaks, drift sand, effectively prevent and treat the common common quality defect of the other types drill hole pouring piles such as hole, constriction that collapse;
2, make full use of the anti-bending strength of sleeve filling pile and the sealing performance of rotary churning pile, adopt all casing drill bored pile, handling safety, the work progress mud-less pollution, the reinforced concrete pile of pouring moulding is rule neatly;
3, still less, construction is to the influence of surrounding environment and pollute minimum than the earthwork excavated volume of the row of piles stake of traditional drill hole, diaphragm wall technology;
4, want than traditional diaphragm wall, boring and pile driving construction speed is faster, cost is lower, and do not change or destroy peripheral underground soil structures and environment;
5, sleeve filling pile and rotary churning pile can accomplish that in construction total length do not have seam construction, can be divided into a plurality of construction sections and can not form construction section interface seepage, form the flowing water construction operation easily, have improved efficiency of construction.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated to the utility model.
As shown in Figure 1, the job practices of the water-stop curtain of the utility model embodiment mainly comprises:
101, as shown in Figure 2, to forming the gathering sill 4 of reserving sleeve filling pile construction position 2 and jet grouting pile construction position 3 in the construction section C of foundation pit walls 1 outside B top;
102, the sleeve filling pile construction is carried out in the sleeve filling pile construction position 2 in construction section, forms sleeve filling pile, and particularly, step 102 can comprise flow process as shown in Figure 3:
301, drill machine with casing is in place;
302, with sleeve pipe centered cover pipe perfusion pile construction in place position 2;
303, the verticality of observing and controlling sleeve pipe;
304, adopt drill machine with casing to be pressed into the first segment sleeve pipe to sleeve filling pile construction position 2;
305, the sleeve pipe position grabbed bucket fetch earth;
306, sleeve pipe creeps into until the sleeve filling pile projected depth by joint, forms the sleeve filling pile hole;
307, the cleaning loosened soil is also inspected for acceptance;
308, in the sleeve filling pile hole, lay reinforcing cage;
309, the concrete pouring conduit is laid in lifting;
310, adopt the concrete pouring conduit in the sleeve filling pile hole of laying reinforcing cage, to pour into concrete, finally form sleeve filling pile 5;
103; Jet grouting pile construction is carried out in jet grouting pile construction position 3 between the sleeve filling pile construction of accomplishing above-mentioned 301-310 step and adjacent two sleeve filling piles 5 that satisfy the jet grouting pile construction condition; Form rotary churning pile 6 with sleeve filling pile 5 interlocks; Particularly, step 103 can comprise flow process as shown in Figure 4:
401, rig is in place;
402, adopt rig to be holed to the rotary churning pile projected depth in jet grouting pile construction position 3, form the rotary churning pile hole;
