Description
Technical field
The present invention relates to a kind of water sealing structure, particularly to a kind of water-stop curtain device.
Background technology
Utilization is continually developed along with the underground space, civil engineering constantly develops toward depth direction, thus occur in that a large amount of deep-foundation pit engineering, deep basal pit is in digging process, easily being affected by underground water, if groundwater flow pours in too much, not only result in foundation ditch cannot normally use, simultaneously it is also possible to cause the generation of security incident, therefore dewatering measure is abnormal important in deep-foundation pit engineering.And water-stop curtain is a kind of important feature in existing water seal for deep foundation pit, water-stop curtain typically uses and deeply stirs or high-pressure rotary-spray machinery manufacture, in recent years, large-scale curtain rig, due to mobility strong, transition and advantage easy for installation, is widely used, but large-scale curtain rig is when building water-stop curtain, owing to adjacent armored concrete support pile is carried out occlusion overlap joint by curtain pile, uncoupling phenomenon probably occur when overlap joint, the most general water-stop curtain cannot preferably be used in foundation ditch sealing.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, it is provided that a kind of self structure is simple, and slip casting performance is the best, can guarantee that the stagnant water effect of water-stop curtain, reduces the water-stop curtain device of drawdown outside Pit Discharge and foundation ditch.
To achieve these goals, the technical solution used in the present invention is such that the water-stop curtain device of the present invention, including water-stop curtain body, water-stop curtain is the most internal is vertically provided with water-permeable filter layer, water-permeable filter layer is evenly arranged in water-stop curtain, and this is internal, and water-permeable filter layer is hinged with water-stop curtain body inner top surface, rubble filter course it is transversely provided with on water-permeable filter layer, water-permeable filter layer connects through rubble filter course and an injected hole, injected hole and the equal more than one of water-permeable filter layer, and corresponding connection two-by-two, injected hole is arranged in a Grouting Pipe, Grouting Pipe is secured transverse on water-stop curtain body, silicon ash separation layer it is provided with below Grouting Pipe, silicon ash separation layer two ends are arranged through water-stop curtain body, and silicon ash separation layer end is in same level line with water-stop curtain body two sides.
Further, as a kind of concrete version, being additionally provided with aqueduct in Grouting Pipe of the present invention, aqueduct is socketed in Grouting Pipe.
Further, as a kind of concrete version, rubble filter course thickness of the present invention is between two to three centimetres.
Further, as a kind of concrete version, the built-in filter screen of rubble filter course of the present invention, filter screen is set in parallel on rubble filter course.
Further, as a kind of concrete version, the external grouting pump in Grouting Pipe one end of the present invention, Grouting Pipe is provided with the Grouting Pipe joint that grouting pump connects.
Further, as a kind of concrete version, injected hole of the present invention uses tube structure, and it consists of concrete reinforcement structure.
Further, as a kind of concrete version, injected hole of the present invention uses single row or multiple rows hole to arrange.
Compared with prior art, it is an advantage of the current invention that: this water-stop curtain device self structure is simple, and slip casting performance is the best, can guarantee that the stagnant water effect of water-stop curtain, reduce the drawdown outside Pit Discharge and foundation ditch, improve sealing performance on the whole, reduce construction costs simultaneously.
