Pile type spur dike body vibration pile sinking construction method

Abstract

The invention discloses a pile type spur dike body vibration pile sinking construction method. The method includes the following steps of (a) construction of ramps and shortcuts, (b) preparation before pile sinking and foundation cleaning, (c) pile lifting and sheet pile transporting and positioning and (d) sheet pile sinking through vibration. According to the method, reinforced concrete sheet piles are used as a foundation of a spur dike to replace a rockfill spur dike, the foundation is deep, the spur dike can keep stable under the effect of tidal bore and flood scouring, and therefore compared with the traditional rockfill spur dike, the spur dike with the reinforced concrete sheet piles as the foundation can better bear impact of the tidal bore, is not prone to being damaged, is less in maintenance work amount during operating period, overcomes the defect of frequent emergency rescue, has a higher quality safety coefficient, can avoid the situation that river banks are eroded and damaged and a river bed is scoured due to impact of water flow of rivers, improves fairways, forms shoals, conserves water and soil, maintains fluvial facies, and protects water ecological diversity. The construction method is high in practicability and low in post-maintenance cost and has high applicability, considerable economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention relates to a construction method of vibrating pile sinking for a pile type spur dam body. Background technique [0002] The pile-type spur dike construction method mainly studies the rapid and effective completion of prefabricated pile sinking construction problems in the Qiantang River and other rivers, giving full play to the effectiveness of the pile-type spur dike, based on preventing the erosion and damage of the river bank by the impact of the river flow, and in addition to utilizing the spur dike It can reduce the buffering of the river bed, improve the channel, form shoals, maintain water and soil, maintain river facies, and protect the diversification of water ecology. [0003] Since the seawall embankment was reinforced in 1998, the tidal disasters of the Qiantang River have no longer affected residents on both sides of the river, but the tide has become more dangerous due to the narrowing of the river channel. Since 1998, at l...

Problems solved by technology

Traditional spur dams can withstand less impact from tidal surges and are easily damaged, and the maintenance works during the operation period are relatively large, requiring frequent emergency rescues
