Embodiment Construction

[0057] For the convenience of description, the coordinate system is defined as figure 1 shown, and the left-right direction is horizontal, the front-back direction is vertical, and the up-down direction is vertical.

[0058] Such as figure 1 As shown, a ground anchor horse crossing construction equipment includes a main frame body 1, and the upper side of the main frame body 1 is a slope inclined forward and downward. Here, the side with the shorter height of the slope is the front side .

[0059] As a specific implementation, such as figure 1 and image 3As shown, the main frame body 1 includes an obliquely arranged square frame, and the square frame is formed by connecting four profiles (square steel pipes) sequentially by welding. Four corners of the lower side of the square frame are respectively provided with legs extending vertically downwards, and a connecting crossbeam is arranged between two adjacent legs. Preferably, two connecting beams are arranged between ...

Abstract

The invention discloses ground anchor transportation road opening construction equipment, and relates to the technical field of power transmission line construction equipment. The ground anchor transportation road opening construction equipment comprises a main frame body with an inclined upper side face, and a first sliding seat and a second sliding seat are sequentially slidably arranged on theupper side face from top to bottom. A driving sleeve is arranged between the first sliding seat and the second sliding seat, and the front end and the rear end of the driving sleeve are rotationally connected with the first sliding seat and the second sliding seat through bearing assemblies respectively. A hollow drill rod is arranged in the driving sleeve, the hollow drill rod is in threaded connection with the driving sleeve, and a drill bit is fixedly arranged at the front end of the hollow drill rod. A driving motor for driving the driving sleeve to rotate is arranged on the first slidingseat or the second sliding seat. A jacking pin is arranged on the driving sleeve, and when the jacking pin is jacked on the hollow drill rod, the hollow drill rod and the driving sleeve are relativelyfixed. According to the equipment, the damage to undisturbed soil can be reduced to the minimum, the maximum contact surface of an anchor body and the undisturbed soil is ensured, and the pulling resistance is improved.

Description

technical field [0001] The invention relates to the technical field of transmission line construction equipment, in particular to a ground anchor horse crossing construction equipment. Background technique [0002] The stress of the ground anchor depends on the strength of the anchor itself and the allowable uplift force embedded in the soil. During construction, the strength and pull-out resistance of the ground anchor must be calculated. Calculate the depth of ground anchor embedding according to the pullout force and soil quality required for construction. When conditions permit, ground anchor pits can be excavated mechanically. The excavation efficiency is low, and it is easy to cause the collapse of the horse crossing, destroy the undisturbed soil layer, and affect the pullout resistance of the ground anchor. Such as Figure 22 As shown, especially when using 50kN ground anchors (length*width: 900mm*300mm) in soft soil and ordinary soil, the burial depth L must not be ...
