Vibration pile driver for bridge construction

Abstract

The invention discloses a vibration pile driver for bridge construction. The vibration pile driver structurally comprises a walking base, an operation room, a driving table, a traction inhaul cable, a lifting plate, a pile hammer and a pile frame, wherein the operation room controls the driving table, the operation room and the driving table are installed on the walking base, the driving table is connected to the lifting plate through the traction inhaul cable, the pile hammer and the pile frame are movably connected to the lifting plate, and the pile hammer is mechanically connected with the pile frame; and the pile hammer comprises a soil guide device, a soil collecting cavity and a drill bit, the soil guide device is installed on the soil collecting cavity, the drill bit is arranged at the bottom of the soil collecting cavity, and the drill bit is arranged in the pile frame in a matched mode. The soil guide device is matched with the soil collecting cavity, a guide-out opening and a soil inlet formed in the soil guide device are connected with a soil guide pipe, the soil inlet is matched with the soil collecting cavity, soil in the soil collecting cavity is discharged out of the guide-out opening through the soil guide pipe via the soil inlet, the guide-out opening is connected to the exterior of the pile frame, continuous operation of soil guide of the pile hammer is achieved, one-time soil guide is achieved, and the pile driving efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a vibratory pile driver for bridge construction. Background technique [0002] Most of the construction machinery used in bridge construction is general-purpose, a few have evolved into special purpose in adapting to the characteristics of bridge construction, and others are in between the above two. The existing foundation construction machinery used in bridge construction includes vibratory pile drivers , Vibratory pile driver, also known as vibratory pile driver, has several pairs of eccentric wheels, each pair of eccentric wheels rotates synchronously at high speed in opposite directions, and the centrifugal forces generated cancel each other out in the horizontal direction and superimpose in the vertical direction, resulting in There are two types of vertical excitation force, electric and hydraulic, and the vibration force ranges from 1 to 5 MN. It is mainly use...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a vibratory pile driver for bridge construction, which is used to solve the problem that when the pile driver is driven into the construction ground, after the vibrating pile hammer drives the pile frame, the soil accumulated in the pile frame is taken out by the pile hammer. However, due to the limited length of the pile hammer, if the length of the pile frame is longer, the pile hammer needs to be divided into several times to completely bring out the soil in the pile frame, and the technical problem of low piling efficiency
