Problems solved by technology

[0002] During the construction of pile foundations on water, there will be working conditions that the piling ship cannot perform driving. It is necessary to use a guide frame for guided piling. Due to the heavy structure of the piling frame, the moving and fixing process is complicated and difficult, and every time a pile is laid, the piling must be re-moved. frame, the construction efficiency is very low

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, the pile foundation supporting and guiding clamp of the water piling of the present invention includes a joint seat 1, an arc-shaped fixed arm 2, an arc-shaped movable arm 3, an arc-shaped movable arm driving cylinder 4 and an array of support rollers 5. The joint seat 1 is welded The box-shaped body of the structure, the longitudinal ends of the upper and lower plates of the box-shaped body extend outwards to form a front concave shelf 11 and a rear concave shelf 12 respectively, and the left end of the arc-shaped fixed arm 2 and the left end of the arc-shaped movable arm 3 are respectively embedded in both sides of the front concave shelf Inside, the left end of the arc-shaped fixed arm 2 is fixedly connected with the left side of the front concave shelf 11, and the left end of the arc-shaped movable arm 3 is hinged with the front concave shelf 11 right side by a hinge pin 31. The rear recess 12 is embedded in the front end of...

Embodiment 2

[0031] In this embodiment, a roller frame 8 is added, and the two ends of the support shaft 51 are supported in one end of the roller frame 8 , and the other end of the roller frame 8 is fixed on the inner side of the arc-shaped fixed arm 2 or the inner side of the arc-shaped movable arm 3 . For supporting and guiding smaller diameter pile foundations 7 . The rest of the structure of this embodiment is the same as that of Embodiment 1.

[0032] A method for supporting a guide clamp using a pile foundation driven by water piling, comprising the following steps:

[0033] 1) The pile foundation support guide clamp is installed on the front end of the boom 101 of the truck crane 100

[0034] Install the rear end of the pile foundation support guide clamp on the front end of the boom 101 of the truck crane 100 from which the hook device has been removed, and connect the hydraulic oil pipe and the electric control signal line of the arc movable arm drive cylinder 5 to the hydraulic...

Abstract

The invention discloses a pile foundation support and guide clamp for marine piling. The pile foundation support and guide clamp comprises a connector seat, an arc-shaped fixed arm, an arc-shaped movable arm, an arc-shaped movable arm driving cylinder and a plurality of groups of support rollers, wherein one end of the arc-shaped fixed arm is fixedly connected to one side of the front end of the connector seat; one end of the arc-shaped movable arm is hinged to the other side of the front end of the connector seat; both ends of the arc-shaped movable arm driving cylinder are respectively hinged to hinged seats on the outer end of a cross rod and the outer side of the middle part of the arc-shaped movable arm by virtue of transverse pins; each group of the plurality of support rollers of the same diameter are vertically supported in the arc-shaped fixed arm and the arc-shaped movable arm of hollow structures respectively, and the plurality of support rollers are respectively abutted on the excircle of pile foundations. The method comprises the following steps that (1) the pile foundation support and guide clamp is installed on the front end of a suspension arm of an autocrane; (2) the autocrane and the suspension arm are positioned, and the first pile foundation is positioned and sunken; (3) other pile foundations are positioned and sunken. Dozens of pile foundations can be sunken once by the pile foundation support and guide clamp, so that the construction efficiency is greatly improved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a support and guide device for the upper part of a pile foundation during piling on water, in particular to a clamp for the support and guide device and a support and guide method, belonging to the technical field of hydraulic engineering. Background technique [0002] During the construction of pile foundations on water, there will be working conditions that the piling ship cannot perform driving. It is necessary to use a guide frame for guided piling. Due to the heavy structure of the piling frame, the moving and fixing process is complicated and difficult, and every time a pile is placed, the piling must be re-moved. frame, the construction efficiency is very low. Contents of the invention [0003] The object of the present invention is to provide a pile foundation support guide clamp for pile foundation that has a simple structure, can quickly complete the positioning of the pile foundation in all directions, and can sink...
