Abstract
The invention discloses a leaking stoppage method for a waterproof curtain. The method comprises the following steps of (1) drilling a hole in the upper portion of a defect of the waterproof curtain until reaching the defect, (2) stuffing soft ribs into the defect from the drilled hole in the upper portion of the defect until the soft ribs can not be stuffed any more, (3) placing a high-pressure rotary spraying pipe into the drilled hole until reaching the defect, (4) conducting high-pressure rotary spraying on the defect through the high-pressure rotary spraying pipe, and enabling cement paste and the soft ribs at the defect to be solidified in situ to form a reinforced rotary spraying body so as to repair the defect. The soft ribs used in the method play a role in reinforcing, the influence of water flows on forming and solidifying of a pile body can be effectively removed, and the pile body can be kept complete.
Description
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of leakage-plugging method for water-stopping curtain.
Background technology
In prior art, for the defect blocking method of the water-stop curtain of foundation ditch, generally adopt mechanical geotechnological digging mode to expose after leakage point, then carry out leak stopping work, but for the larger situation of water yield, cannot do like this, the difficulty of blocking construction is larger.In prior art, also there is the high-pressure rotary-spray of utilization to repair the defect of water-stop curtain, but due to flowing of underground water, conventional high-pressure rotary jet grouting pile is easily rushed rare washing away by current and cannot form curing stake at fault location, even if add accelerating admixture to be also unable to catch up with the speed of current scour, effect is not satisfactory.
Summary of the invention
The object of the invention is to overcome prior art defect, a kind of leakage-plugging method for water-stopping curtain is provided.
Technical scheme of the present invention is as follows:
A kind of leakage-plugging method for water-stopping curtain, comprises the steps:
(1) above the fault location of water-stop curtain boring to this fault location;
(2) soft muscle body is filled in to this fault location to till not filling in from the top drill hole of defect;
(3) from described drill hole, insert high-pressure rotary-spray pipe to fault location;
(4) by this high-pressure rotary-spray pipe, fault location is carried out to high-pressure rotary-spray, make the soft muscle body in-situ solidifying of cement paste and fault location form reinforcement churning body with correction of the defect place.
In a preferred embodiment of the invention, described soft muscle body is cellucotton.
In a preferred embodiment of the invention, the hydraulic pressure >=38MPa of described high-pressure rotary-spray, blast is 0.7MPa, it is 2～3MPa that slurry is pressed.
In a preferred embodiment of the invention, the rotary speed of described high-pressure rotary-spray is 10r/min, and slurry flow is 100～150L/min.
In a preferred embodiment of the invention, the water/binder ratio of described cement paste is 1.0, and proportion is 1.5～1.6, and returning slurry proportion is 1.2～1.3.
The invention has the beneficial effects as follows:
1, method of the present invention is filled in this fault location to till not filling in by soft muscle body from the top drill hole of the defect of water-stop curtain, at this place, carry out high-pressure rotary-spray again, soft muscle body plays the effect of reinforcement, can effectively eliminate the impact of current on pile body forming and hardening, makes pile body keep complete;
2, cement churning body of the present invention is after the reinforced action of soft muscle body, and intensity is improved, and the stability of sealing is stronger;
3, method of the present invention adopts cellucotton as soft muscle body, with low cost;
4, method of the present invention can effectively be processed the defect that water yield is large and needn't excavate on a large scale with correction of the defect place, and activities is ripe simple, respond well, with low cost.
The specific embodiment
By the specific embodiment, technical scheme of the present invention is further detailed and is described below.
A kind of leakage-plugging method for water-stopping curtain, comprises the steps:
