Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] see figure 1 , the drilling type rapid hole-forming system of the present invention comprises a power unit 2, a hollow drill rod 5, a drill bit 6, a vacuum pump 1 and a dredge pump 3, the power unit 2 is connected to the rear end of the hollow drill rod 5, and the drill bit 6 is connected to the The front end of the hollow drill rod 5 is connected with the vacuum pump 1 and the dredge pump 3 respectively.

[0033] In this example, the power of the power unit is 40-50KW, and the diameter of the hollow drill rod is 20-25cm. Large-diameter hollow drill pipe is used to discharge mud by pump suction reverse circulation principle, with strong suction capacity and fast hole forming speed. The drill bit is a cutting drill bit, which makes the muck after cutting into strips, which can improve the working efficiency. In this example, the combination of a high-power p...

Abstract

The invention relates to a pore-forming device and a pore-forming process in civil engineering, in particular to a drilling-type quick pore-forming system and a drilling-type quick pore-forming process. The drilling-type quick pore-forming system comprises a power device, a hollow drilling rod, a drill bit, a vacuum pump and a dredge pump. The power device is connected at the tail end of the hollow drilling rod, the drill bit is connected at the front end of hollow drilling rod, and the hollow drilling rod is respectively connected with the vacuum pump and the dredge pump. Compared with the prior art, the drilling-type quick pore-forming system has the advantages that pore-forming speed is increased by 2.5-3 times those of conventional pore-forming speeds, so that a pore-forming cycle can be shortened, and the drilling-type quick pore-forming system is particularly suitable for being used under circumstances that rapid construction is required or requirements on neighboring environment protection are high.

Description

technical field [0001] The invention relates to a hole-forming device and a hole-forming process in civil engineering, in particular to a drilling-type rapid hole-forming system and a drilling-type rapid hole-forming process. Background technique [0002] At present, in pile foundation construction, the hole-forming method that often adopts is rotary drilling rig slurry mud retaining wall forming hole, and rotary drilling rig is suitable for soft soil layer. However, there are following defects in the current rotary drilling rig mud retaining wall forming method: [0003] 1. The hole forming speed is slow and the hole forming cycle is long; [0004] 2. The whole process of hole formation adopts mud wall protection, and the discharge of mud is relatively large, which will cause certain pollution to the environment. Contents of the invention [0005] The purpose of the present invention is to provide a drilling-type rapid hole-forming system to solve the technical problems...
