Piling process for building sheet pile type wharf in shallow coastal water

Abstract

The invention relates to a piling process for building a sheet pile type wharf in shallow coastal water. The process comprises the following steps: 1) a propelled flat barge, a self-propelled flat barge and a pile-transporting barge anchor in a construction area where sheet piles are to piled, the barges are positioned; 2) two theodolites are used to position and measure a guide pile in a right angle intersection manner, a land crawler crane on each flat barge is used to pile three guide piles in turn; 3) each crawler crane is used to arranged a moving back plate to clamp the moving back plate with a guide beam; 4) a scow crane is used to to lift a sheet pile from the pile-transporting barge in a three-point manner and place the sheet pile near the side of a pile driver; and 5) the sheet pile is sleeved in a follower, the self-sinking of the sheet pile is performed, when the sheet pile is stable, the sheet pile is hammered to sink, the above steps are repeated until all the sheet piles are piled, and the construction is completed. By adopting the process, the construction difficulty of piling the sheet pile in shallow water can be solved better; and the workload for piling the auxiliary guide pile is reduced and the construction cost of the sheet pile is reduced, thus the piling process has great practical application value and promotion value.

Description

Technical field: [0001] The invention belongs to a construction method of a sheet pile wharf, and in particular relates to a piling process method for building a sheet pile wharf in a nearshore shallow water area. Background technique [0002] Due to the simple structure, less material consumption, convenient construction and fast speed, the sheet piling wharf can excavate the harbor basin after laying the sheet piling first, greatly reducing earthwork excavation, and is especially suitable for the construction of small and medium-sized wharves in nearshore waters. Sheet pile wharves are generally built at the junction of water and land in nearshore waters. The construction area usually has a thicker mud layer on the original mud surface and a smaller water depth. During sheet pile construction, there will be contradictions between the insufficient bearing capacity of the foundation using land piling machines and the insufficient water depth of professional piling ships. , w...

Sheet pile wharves are generally built at the junction of water and land in nearshore waters. The construction area usually has a thicker mud layer on the original mud surface and a smaller water depth. During sheet pile construction, there will be contradictions between the insufficient bearing capacity of the foundation using land piling machines and the insufficient water depth of professional piling ships. , which brings great difficulties to sheet pile construction, and also limits the scope of application of sheet pile wharf
