Description

Technical Field

[0001] The utility model relates to a bored pile drilling positioning device, in particular to a bored pile drilling positioning device for bridge construction. Background Art

[0002] With the continuous expansion of the city, road bridges have become an indispensable part of urban construction. During the bridge construction process, bored pile drilling equipment is often used. A bored pile is formed by drilling a hole at the pile position and then placing steel bars and pouring concrete. Due to the advantages of no vibration, no soil extrusion, and low noise during the construction of bored piles, it is widely used in dense building areas such as urban construction.

[0003] The existing bored pile drilling equipment still has the following problems: Since the depth of the bored piles used in bridge construction is relatively deep, the length of the drill pipe will be relatively long, so the overall height of the bored pile drilling equipment is relatively high. If it encounters a bridge or height limit, it is not convenient for transportation, and even the passage is blocked; Although there is also a bored pile drilling equipment that can adjust the position of the drilling mechanism to reduce its overall height, it is prone to serious deviation of the overall center of gravity of the bored pile drilling equipment during adjustment, resulting in poor stability and being not conducive to drilling positioning. Summary of the Utility Model

[0004] The main purpose of the present disclosure is to provide a bored pile drilling positioning device to effectively solve the problems raised by the inventor in the above background art.

[0015] (2). In this application, before the drilling construction, the hydraulic push rod works. The hydraulic push rod drives the counterweight to move to the right. The counterweight will drive the X-axis rack to move to the right.
