Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a bottom plate anti-seepage structure composed of a thorn wall, a steel sheet pile and a copper sheet. Background Art
[0002] Soft soil is widely distributed in the southeastern coastal areas of my country. Soft soil foundations are characterized by deep soil layers, high natural water content, large porosity, high compressibility, low bearing capacity, and under-consolidation. In order to prevent the settlement of hydraulic structures, hydraulic structures on soft soil foundations are mostly treated with pile foundations. Since there is a certain head difference between the upstream and downstream of hydraulic structures, especially when the foundation soil is under-consolidated soil such as silt and silty soil, the soft soil on both sides of the building and under the bottom plate often becomes hollow, forming a permeation channel, thereby causing permeation damage and seriously affecting the safety of the building.
[0003] In order to prevent lateral seepage damage to buildings, barbed walls are usually set up on the sides of buildings to block water from seeping around the side piers, extend the seepage path, and reduce the seepage pressure on the side piers. In order to prevent the deep soft soil foundation from being hollowed out and forming seepage damage, the bottom of hydraulic structures generally adopts anti-seepage wall structures such as reinforced concrete sheet pile anti-seepage wall, cement soil mixing pile anti-seepage wall, and high-pressure grouting anti-seepage wall. Reinforced concrete sheet pile anti-seepage wall has the advantages of flexible design, good durability, and low price, but its structure has a large deadweight and requires heavy machinery for construction. During the construction of cement mixing piles and high-pressure grouting (rotary grouting, fixed grouting, swing grouting) grouting anti-seepage walls, problems such as poor integrity and low strength of the pile body caused by uneven pile body quality and ineffective overlap of the lower part of the wall due to vertical deviation of the pile body are prone to occur. The settlement of soil between piles will have a downward pull on the anti-seepage wall. The tensile strength of cement mixing piles or high-pressure grouting anti-seepage walls is low, and they are easily separated from the bottom plate under the action of downward pull load, causing the anti-seepage wall to fail.
[0004] Steel sheet pile anti-seepage wall has the advantages of light weight, high strength, good locking and water-stopping effect, fast construction speed, high safety, good durability, and significant environmental protection effect. It has been widely used in recent years. Permanent deformation joints such as settlement joints and expansion joints are usually set up in hydraulic structures along the water flow direction. Copper sheets are usually used for water-stopping at the joints of hydraulic structures. It is particularly important to reliably fix the steel sheet pile anti-seepage wall with the reinforced concrete bottom plate and the barbed wall bottom plate, and combine it with horizontal and vertical copper sheets to form a complete anti-seepage system at the joints.

[0005] The purpose of the utility model is to provide a bottom plate anti-seepage structure composed of a barbed wall, a steel sheet pile and a copper sheet, which effectively combines the barbed wall, the steel sheet pile and the copper sheet to form a complete anti-seepage system at the joints, thereby ensuring the safety of the building and solving the problems raised in the above-mentioned background technology.

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Example 1: Figures 1-2 As shown, a bottom plate anti-seepage structure composed of a barbed wall, a steel sheet pile and a copper sheet comprises a steel sheet pile 1, a reinforced concrete bottom plate 2, a horizontal copper sheet 3, a vertical copper sheet 4 and a pile foundation 5; a side anti-seepage barbed wall bottom plate 7 is provided at the edge of the reinforced concrete bottom plate 2, and a barbed wall is provided on the barbed wall bottom plate 7; the top ends of the steel sheet pile 1 and the pile foundation 5 extend into the bottom of the reinforced concrete bottom plate 2, the horizontal copper sheet 3 and the vertical copper sheet 4 are embedded in and connected to the end face of the reinforced concrete bottom plate 2, and the horizontal copper sheet 3 and the vertical copper sheet 4 are connected by a water-stopping device, and the bottom end of the vertical copper sheet 4 is connected to the steel sheet pile 1 to form an anti-seepage seal; a joint 8 is provided between adjacent end faces of the reinforced concrete bottom plate 2, and the joint 8 is filled with a caulking plate.
[0022] The reinforced concrete bottom plate 2 , the thorn wall bottom plate 7 and the thorn wall are integrally cast and formed, and one end of the thorn wall bottom plate 7 protrudes from the reinforced concrete bottom plate 2 .
[0023] There are multiple steel sheet piles 1 arranged in parallel, and the steel sheet piles 1 extend into the reinforced concrete bottom plate 2 by no less than 30 cm.
[0024] There are four pile foundations 5 arranged in a rectangular array, and the pile foundations 5 extend into the reinforced concrete bottom plate 2 by no less than 10 cm.
