Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0032] Referring to the accompanying drawings, a seepage-proof and liquefaction-resistant floating sluice foundation is shown in the figure, including an empty tank gate bottom plate 100, a continuous closed sheet pile 200, a concrete bottom plate 300 and a flexible sealing structure.

[0033] The bottom plate 100 of the empty box gate is placed on the foundation, and it is made of a reinforced concrete structure or a prestressed reinforced concrete structure.

[0034] The continuous closed sheet pile 200 is arranged around the bottom plate of the empty box gate 100 and sunk into the foundation, and it is formed by a sheet pile capable of forming a seal, such as a prefabricated reinforced concrete sheet pile, a steel sheet pile, and the like.

Abstract

The invention discloses a seepage-proofing and anti-liquefaction floating transportation sluice foundation. The floating transportation sluice foundation comprises a vacant box sluice bottom board arranged on the foundation, continuous closing sheet piles which are arranged around the vacant box sluice bottom board and submerged into the foundation, a concrete floor which is arranged around the vacant box sluice bottom board and connected with the pile tops of the continuous closing sheet piles, and a flexible sealing structure which is arranged between the vacant box sluice bottom board and the concrete floor so as to achieve flexible sealing closing between the vacant box sluice bottom board and the concrete floor. The invention further discloses a construction method of the seepage-proofing and anti-liquefaction floating transportation sluice foundation. The seepage-proofing and anti-liquefaction floating transportation sluice foundation and the construction method thereof have the advantage that the seepage problem of a floating transportation sluice and the liquefaction problem of the foundation can be solved at the same time through the prefabricated vacant box sluice bottom board, the concrete floor arranged around the vacant box sluice bottom board, the flexible sealing structure arranged between the vacant box sluice bottom board and the concrete floor, and the continuous closing sheet piles.

Description

technical field [0001] The invention relates to the technical field of reclamation engineering, in particular to a floating sluice foundation suitable for anti-seepage and anti-liquefaction in reclamation engineering and a construction method thereof. Background technique [0002] Floating sluices are used in reclamation projects, which can solve temporary drainage and permanent drainage problems at the same time, and can realize factory production, shorten the construction period, and save investment costs without reclamation. However, in the reclamation project, the geological conditions of the gate site are poor, and most of the surface layer is silt or muddy silt, and the foundation pit of the floating sluice is excavated underwater, and the flatness of the foundation surface is difficult to control. On the one hand, the tidal level outside the enclosure changes greatly, and the water head difference inside and outside the enclosure is large, so the sluice foundation is ...
