Piling method of sheet pile retaining structure and hanger type pile hammer

Abstract

The invention discloses a piling method of a sheet pile retaining structure. The piling method comprises the following steps that a target sheet pile and a hanger type pile hammer are correspondinglyarranged, and the pile hammer is installed on a tower frame of a pile driver; if sheet piles are a plurality of steel tube lock catch piles, sheet pile follower caps are installed at the lower end ofthe pile hammer, and the sheet pile follower caps are used for enabling the steel tube lock catch piles to sink into a foundation soil one by one; if the sheet piles are a plurality of steel plate lock catch piles, sheet pile follower caps are installed at the lower end of the pile hammer, and the sheet pile follower caps are used for enabling the steel plate lock catch piles to sink into the foundation soil one by one; and if the sheet piles are formed by combining the multiple steel tube lock catch piles and the multiple steel plate lock catch piles, all the steel tube lock catch piles and the steel plate lock catch piles sink into the foundation soil one by one. The invention further discloses the hanger type pile hammer implementing the piling method. The piling method of the sheet pile retaining structure and the hanger type pile hammer can be applied to the sheet pile retaining construction of multiple pile type combination, the load intensity of a sheet pile structure of the multiple pile type combination can be improved, multiple use of a hammer is achieved, the equipment cost is saved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction equipment, in particular to a piling method for a sheet pile enclosure structure and a hanger type piling hammer. Background technique [0002] In the prior art, enclosure refers to enclosures on all sides of buildings and rooms. Sheet pile is a kind of protective pile, which is long and flat in shape and can be used for protection of low slopes and foundation pits. Sheet pile enclosure refers to the use of sheet piles as enclosures. Sheet pile enclosure construction has little damage to the environment, convenient construction, and short construction period. It is suitable for vertical earthwork excavation and underground engineering construction due to site and other conditions, especially for various buildings, rivers, lakes, oceans, etc. Foundation pit, embankment, bank slope enclosure construction. [0003] Sheet pile enclosure means that in the construction area, the ...

Problems solved by technology

Existing steel sheet piles consist of multiple steel pipe pile locks and / or multiple Larsen U-shaped steel plate locks. For the construction of steel sheet piles with two types of sheet pile piles, the traditional method generally uses two different Two pile types of sheet piles are completed with advanced equipment, which affects the construction efficiency and increases the construction cost

[0007] In the prior art, the inventor applied for and disclosed a hydraulic piling hammer with an improved structure, the application number is: CN03274785.3, the pile cap is fixedly connected with the pile hammer, but it can only complete one type of steel pipe Pile construction, unable to complete the construction of steel sheet piles with various pile types
