Abstract
The invention discloses drilling equipment for a building pile foundation with a square cross section, which comprises a power device, a hydraulic support, an upper supporting rod, a drill rod and a drill bit, wherein hydraulic support is connected with the power device and the drill rod; the upper end of the drill rod is inserted into the upper supporting rod; the middle part of the drill rod is inserted into a supporting piece; the bottom end of the drill bit is arranged in the pile foundation and is fixedly connected with the drill rod; the drill bit is provided with a hole, and the bottom end o the drill bit is provided with a drill point; and the cross section of the drill bit is of a triangle-like shape, and the center diameter of the drill bit is equal to the length of the cross section of the pile foundation or the side length of the cross section of the pile foundation is increased by adopting a hole-expanding construction method. According to the drilling equipment for the building pile foundation with the square cross section, the pile foundation with the square cross section is directly drilled by adopting machinery, the work efficiency is greatly improved, and security risks of manual well descending can be eliminated. The drilling equipment disclosed by the invention is simple in overall structure, high in novelty and easy to popularize and apply.
Description
Technical field
The present invention relates to a kind of rig, be specially the rig of a kind of building square-section pile foundation.
Background technology
Rig, very general in architectural use.
The pile foundation boring machineries such as existing building, bridge, the stake holes come outbreak out can only be circular cross-section, but in Practical Project, designing unit when carrying out the industry design such as house, light rail, bridge, mine, electric power, railway still often adopt square-section stake, current square hole pile foundation can only adopt hand excavation, every day only about 1 meter, drilling depth, efficiency is lower, and after hole depth is more than 25 meters, can produce very large security risk to underground operators, the workman every year because of excavated by manual work stake injures and deaths is numerous.
In order to realize getting out square-section stake, and realizing the effect that gets out fast when the degree of depth is not limit, will design that a kind of can to carry out the drilling equipment that the degree of depth gets out cross section stake be people's technical issues that need to address.
Summary of the invention
The object of the present invention is to provide the rig of a kind of building square-section pile foundation, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: the rig of a kind of building square-section pile foundation, comprises power set, hydraulic pressure support, upper support bar, drilling rod and drill bit; Described hydraulic pressure support connecting power device and drilling rod; Described drilling rod upper end is inserted in upper support bar; Be inserted in the middle part of described drilling rod in support member; Described drill bit bottom is arranged in pile foundation, and is fixedly connected with drilling rod; Described drill bit is offered porose, and drill bit bottom is provided with apex point; Described drill bit cross section is class triangular shape, and the limit in pile foundation cross section is more than or equal to the center radius of described drill bit.
Further, described support member is fixedly mounted on pile foundation upper end.
Further, described drilling rod upper end is inserted in upper support bar; Be inserted in support member in the middle part of described drilling rod.
Further, drilling rod can adopt the spreading that is rigidly connected, and deepens drilling depth.
Further, with scale label or the display of employing electronic curtain on drilling rod, real-time directly reading drilling depth.
Further, drill bit and drilling rod are switching with rotating counterclockwise with turning to different rotating speeds clockwise between the two according to operator instruction.
Compared with prior art, the invention has the beneficial effects as follows: the rig of this building square-section pile foundation, adopt machinery to be directly drilled to square-section pile foundation, greatly increase work efficiency, and the security risk of manually going into the well can be eliminated.Overall structure is simple, and novelty is strong, is easy to promote the use of.
