Highway bridge pile foundation drilling device and using method thereof

Abstract

The invention provides a highway bridge pile foundation drilling device and a using method thereof. The highway bridge pile foundation drilling device comprises an excavator main body and a mechanicalarm, a main body bin is arranged at the end, away from the excavator main body, of the mechanical arm, a telescopic hydraulic cylinder A is arranged at the end, close to the main body bin, of the topof the mechanical arm, a clamping plate is arranged at the output end of the telescopic hydraulic cylinder A, and the end, close to the main body bin, of the clamping plate is fixedly connected withthe main body bin. Through cooperative use of the mechanical arm, the clamping plate, a sliding groove, a fixing screw, a buckle and a drill bit, the inclination angle of the main body bin can be freely adjusted, meanwhile, the rotating stability of the rotating rod is improved through a U-shaped support and a bearing, and the stability of the motor bin and the U-shaped support in the moving process is improved through a sliding block and the sliding groove; and the device can be adjusted to different inclination angles, so that the device can conveniently drill holes in the ground with different gradients, it is guaranteed that the holes of a pile foundation can reach the expected standard, and the quality of subsequent highway bridge construction is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pile foundation drilling, in particular to a highway bridge pile foundation drilling device and a method for using the same. Background technique [0002] Pile foundation engineering is an engineering term. The construction of cast-in-situ piles is divided into two parts: hole formation and pile formation. Therefore, the inspection of pile foundations can be divided into two parts: hole formation quality inspection and pile formation quality inspection. The first link in pile construction. [0003] Most of the current pile foundation drilling devices are directly installed on the corresponding mechanical arms. Although it is possible to drill holes on ground with different slopes, during the drilling process, only relying on the mechanical arm for support cannot guarantee that the drilling device The stability during the drilling process cannot further improve the stability of the drilling device to ensu...

Problems solved by technology

[0003] Most of the current pile foundation drilling devices are directly installed on the corresponding mechanical arms. Although it is possible to drill holes on ground with different slopes, during the drilling process, only relying on the mechanical arm for support cannot guarantee that the drilling device The stability during the drilling process cannot further improve the stability of the drilling device to ensure that the holes in the pile foundation can meet the expected standards; currently, when constructing cast-in-situ piles, it is usually necessary to drill holes at the corresponding positions on the ground first. , During the drilling process, the discharged soil is often concentrated near the hole. If the soil quality is relatively loose, the soil next to the hole is easy to fall into the hole again, causing the depth of the hole to fall into the soil, and it is easy to affect the follow-up The effect of concrete pouring; and the current drilling device is often removed directly from the hole after drilling. If the soil in this area is relatively loose, the soil on the inner wall of the hole will easily collapse after the drill bit is removed and fall into the cavity. It affects the actual use effect of the hole, and it is impossible to tighten the inner wall of the hole in time after the hole is drilled to ensure that the inner wall of the hole is more stable; at the same time, after the current drilling device is continuously drilling, most of its drive motor Heat dissipation dissipates heat to the external environment, and it is impossible to improve the heat dissipation effect of the drive motor and at the same time discharge the dust generated by drilling in a directional manner, so as to avoid dust flying around the drilling device and affect the operator's observation of the drilling place
