Description

Technical Field

[0001] This utility model relates to the field of cofferdam construction technology, and in particular to a guide device for a steel casing integrated fixed corbel steel sheet pile. Background Technology

[0002] In today's booming marine engineering and numerous water-related infrastructure construction fields, such as the construction of bridge pier foundations for cross-sea bridges, the expansion and construction of coastal port terminals, and the construction of inland waterway locks, steel sheet pile cofferdams have been widely used as a key temporary water-retaining and soil-blocking structure.

[0003] Traditional sheet pile cofferdam construction methods often suffer from a lack of precise and effective guiding devices during sheet pile driving, resulting in significant deviations in the pile insertion position and difficulty in controlling the pile inclination angle. This not only affects the overall sealing of the cofferdam, easily leading to leakage problems, threatening construction safety within the foundation pit, and increasing drainage costs and construction difficulty, but also causes dimensional deviations during subsequent structural construction, affecting project quality.

[0004] On the other hand, the marine and aquatic environment is complex and changeable, and factors such as water flow speed, tidal fluctuations, and differences in geological conditions pose numerous challenges to the construction of sheet pile cofferdams. Furthermore, traditional guidance methods are rudimentary, and the position of the sheet piles often needs to be repeatedly adjusted during construction, consuming a large amount of manpower, material resources, and time, and extending the project period.

[0005] Therefore, there is an urgent need to provide a steel sheet pile guiding device with high stability and the ability to be assembled to improve construction efficiency. Utility Model Content

[0009] Preferably, the side wall of the last section of the steel casing is provided with a vertically continuous sliding groove, and a limiting block is provided in the sliding groove.

[0010] Preferably, the electro-hydraulic connecting rod includes an adjusting control section and an extension section; the extension section is disposed at both ends of the adjusting control section 7, and a sliding groove fitting block is provided at the end of the extension section away from the adjusting control section; the sliding groove fitting block is embedded in the sliding groove.

[0011] Preferably, the steel bracket includes a crossbar and a diagonal bar; one end of the crossbar is provided with a sliding groove and the other end is provided with a bolt pre-drilled hole; one end of the diagonal bar is connected to the middle of the crossbar and the other end is connected to a limiting block, which is located in the sliding groove.

[0012] Preferably, the limiting guide frame is provided with a steel sheet pile coupling groove; the limiting guide frame is connected and fixed to the crossbar by high-strength bolts.

[0013] The beneficial effects of this utility model are:

[0014] 1) The steel sheet pile guiding device involved in this utility model adopts an electro-hydraulic connecting rod to replace the traditional steel structure welded connectors, which effectively reduces the installation difficulty of the steel casing connectors on site, improves the safety of operation, and enables efficient dismantling and recycling.

[0015] 2) The sheet pile guiding device involved in this utility model adopts a limiting guide frame to replace the traditional single steel guide frame. A steel bracket is set with a sliding groove towards the outer periphery of the steel casing. The limiting guide frame is installed by the steel bracket, which can greatly improve the erection accuracy of the sheet pile, reduce the adjustment frequency of the sheet pile, and improve the efficiency of on-site operation.
