Problems solved by technology

Different from single pile sinking, generally the U-shaped steel sheet piles in the front row are continuous, and the adjacent steel sheet piles must be locked and connected by locks to play a water-retaining role. During construction, the vertical position perpendicular to the design axis is mainly controlled. Because once the previous steel sheet pile is inaccurately positioned and deviates from the design axis, it will be difficult to adjust the latter steel sheet pile in place. The hidden danger of the tenon cannot play the role of water retaining

Embodiment Construction

[0032] 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.

[0033] U-shaped steel sheet piles are often used in projects with high waterproof requirements such as piers, rocks, fixings, breakwaters, diversion dikes, buoys, docks, sluices, water pipes, foundations, anti-seepage walls, and retaining walls. With the continuous improvement of engineering water-stop requirements, U-shaped steel sheet piles have developed from the initial U-shaped grooves to the Larsen steel sheet piles that are commonly used today, and their anti-seepage and water-stop capabilities have been greatly improved.

[0034] However, the lock of the Larsen steel sheet pile is prone to tripping during the pile sinking process, and the water-stop function is still limited. Compared with the Larsen steel sheet pile, the locking U-shape...

Abstract

The invention discloses a large U-shaped steel sheet pile construction technology. The large U-shaped steel sheet pile construction technology comprises the steps of digging grooves in the corresponding driven positions of U-shaped steel sheet piles; and carrying out insertion and vibration sinking on a plurality of U-shaped steel sheet piles in a segmented manner, and carrying out limiting and guiding on each U-shaped steel sheet pile from top and the from the bottom at the same time in the process of insertion and vibration sinking. With the large U-shaped steel sheet pile construction technology, the accuracy of pile sinking is high, and pile deviation and the pile top elevation can be effectively controlled.

Description

technical field [0001] The invention relates to water conservancy projects, in particular to the regulation technology of inland waterways. Background technique [0002] In the case of more and more congested roads, fully exploiting the function of inland waterway shipping for container transportation will support and promote the overall development of the future economic society from many aspects. According to the development experience of international container hub ports, inland water containers are a crucial means of collection and distribution for large container ports. The development and improvement of inland waterways has become a relatively important project for social development. [0003] The development and renovation of inland waterways generally include the following projects: [0004] Dredging and excavation of waterways; revetment works of waterways; berthing area engineering; drainage engineering along waterway revetment; tributary bridges and their approac...
