Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy and hydropower project construction, and particularly relates to a water isolation curtain and a splicing method thereof. BACKGROUND

[0002] In the construction of water conservancy and hydropower projects in river basins, some high dams and large reservoirs are often built to improve engineering benefits. Due to the large reservoir capacity and slow flow rate, obvious temperature stratification occurs during the transition from spring to summer. The water temperature of the outflow of the reservoir is lower than that of the natural river due to the low elevation of the water intake of the hydropower station or water discharge facility for power generation requirements, which causes changes in the water temperature of the natural river downstream of the dam, and has adverse effects on farmland irrigation, industrial water supply, domestic water supply, water quality and ecological balance of downstream rivers, and utilization of water in the reservoir area.

[0003] In recent years, some flexible water-blocking curtain structures with simple structure and relatively low investment have been gradually used to control the problem of low-temperature water discharge from high dams and large reservoirs. Due to the large area of the region used, the water isolation curtain has a large area, and the water isolation curtain is generally spliced, and horizontal joints are often used. At present, rigid connections such as aluminum alloy buckles are often used at the joints. The rigid connection has many connection points, and the weight is increased, and the load at the joint is large, and with the increase of the height, the load is gradually superimposed, so that the water isolation curtain bears the maximum load. In addition, the joint of the rigid connection has poor anti-seepage effect. SUMMARY

[0004] The purpose of the present application is to provide a water isolation curtain and a splicing method thereof, which solves the problems of stress concentration and large load at the horizontal joint of the water isolation curtain, large weight of the rigid connection, damage to the curtain caused by the rigid connection, and leakage at the joint.

[0005] The technical solution of the present application is: a water isolation curtain includes a plurality of curtain bodies spliced with each other, and a splicing structure for connecting the plurality of curtain bodies spliced with each other; the splicing structure includes a first cable-strut, a second cable-strut, and a connecting assembly; the periphery of the curtain body is provided with a skirt, one of the skirts of two adjacent curtain bodies is wrapped around the first cable-strut to form a first edge wrapping cable, and the skirt is folded to form a first edge folding after being wrapped around the first cable-strut; the other skirt is wrapped around the second cable-strut to form a second edge wrapping cable, and the skirt is folded to form a second edge folding after being wrapped around the second cable-strut; a space capable of accommodating the first edge wrapping cable is arranged in the second edge wrapping cable, and the first edge wrapping cable is arranged in the space so that the first edge folding and the second edge folding are coincident to form a plurality of layers, and the connecting assembly is fixed at the coincident position of the plurality of layers.

[0006] In the above scheme, the skirt edge surrounds the cable rod to form a rigid edge of the edge cable, and the edge cables on the two adjacent skirt edges are fixed in an embracing manner, so that the two assembled skirt edges are folded to form multiple layers and then fixed, which can cancel the rigid connection of the aluminum alloy buckle, thereby improving the tightness of the connection, and solving the problems of large stress concentration load of the horizontal joint of the waterproof curtain, large weight of the connection structure, and joint leakage.

[0007] In order to further ensure that the curtain body joint does not leak water, the skirt edge forms the first folded edge in a one-way and one-time surrounding manner, and the skirt edge forms the second folded edge in a one-way or two-way and two-time surrounding manner.

[0008] In order to effectively fix the superimposed multiple layers of skirt edges, the connection assembly includes a clamping plate, a bolt and a nut, the clamping plate is arranged on the outer side of the superimposed first folded edge and second folded edge, the bolt passes through the clamping plate, the first folded edge and the second folded edge and is fixed by the nut. And through the fixing mode of the bolt and the nut, the effective adjustment of the clamping force applied to the skirt edge can be realized.

[0009] Preferably, the clamping plate extends along the length direction of the skirt edge, and the bolt and the nut are arranged on the clamping plate. The clamping plate is designed to be equal in length to the skirt edge, which can effectively clamp and lock the skirt edge and avoid water leakage.

[0010] In order to avoid the wear caused by the direct contact between the connection assembly and the skirt edge, a plurality of openings are arranged on the skirt edge, a ring is arranged in the opening, and the bolt passes through the ring.

[0011] Preferably, the connection between the curtain body and the skirt edge is wrapped with a third cable rod, a plurality of connecting rings are arranged on the third cable rod, and the connecting rings between the adjacent two curtain bodies are connected by a reinforcing cable. The above connection mode ensures the stability of the connection, and reduces the joint stress of the upper and lower waterproof curtains and the transmission and superposition of the force between the curtains. The reinforcing cable and the connecting ring can constrain the displacement of the joint before and after.

[0012] In order to realize convenient and quick detachable connection, the two ends of the reinforcing cable are provided with shackles, and the shackles are detachably connected with the curtain body. The shackles can be selected as arc-shaped shackles, and when the reinforcing cable is connected to the shackles, the shackles can provide a degree of freedom of swinging. The length of the shackle is narrower than that of the skirt edge, which can protect the skirt edge.

[0013] In order to ensure the anti-seepage effect of the joint, a joint glue is arranged at the superimposed position of the first folded edge and the second folded edge.

[0014] The application also provides a splicing method of the above-mentioned waterproof curtain, which comprises the following steps:

[0015] Step 1: align the joints of two curtain bodies;

[0016] Step two, the skirt edges of the two curtain bodies are spread to each other, a first cable rod is placed on the skirt edge of one of the curtain bodies B, and the skirt edge is overlapped after being wrapped around the first cable rod in one direction; a first cable rod is placed on the skirt edge of the other curtain body C, and the skirt edge is overlapped after being wrapped around the first cable rod in one direction; the skirt edge of the curtain body B is placed on the upper surface of the skirt edge of the curtain body C, the skirt edge of the curtain body C is stretched out of the skirt edge of the curtain body B, and the skirt edge of the curtain body C is overlapped after being wrapped around the skirt edge of the curtain body B in one direction;

[0017] Step three, the connecting assembly is fixed at the overlapped position of the skirt edges of the two curtain bodies;

[0018] Step four, other curtain bodies are spliced by the above method; until the water isolation curtain splicing is completed.

[0019] Preferably, in step two, the outer surfaces of the skirt edges of the two adjacent curtain bodies wrapped around the cable rod are cleaned, and the two skirt edges are adhered and fixed by applying joint adhesive. The joint adhesive is not dissolved in water, can be quickly bonded, and has good durability. The skirt edges are aligned before bonding, and cannot be moved at will after bonding.

[0020] Compared with the related art, the present application has the following beneficial effects:

[0021] Firstly, the present application realizes the flexible connection structure of the horizontal joint of the water isolation curtain, which has light weight and large redundant deformation, can release the stress of the horizontal joint structure, and reduces the design load and stress concentration of the water isolation curtain.

[0022] Secondly, the skirt edges of the curtain body joint are clamped by the clamps, the structure connection is firm, the bending and wrapping structure of the skirt joint can increase the anti-seepage effect of the joint, and the construction is convenient.

[0023] Thirdly, the present application solves the problems of large stress concentration load of the horizontal joint of the water isolation curtain, heavy weight of the connection structure, joint leakage, and damage of the curtain caused by the rigid connection, reduces the load of the upper water isolation curtain and the joint, avoids the stress concentration caused by the large deformation of the vertical cable during the manufacturing and installation process, enhances the firmness and anti-seepage function of the joint structure, and the structure connection is simple and easy to operate.
