Abstract
An inverted plumb line hole constructing device comprises a drill and a combination multi-stage variable diameter drill bit. The drill is connected with the combination multi-stage variable diameter drill bit through threads. The combination multi-stage variable diameter drill bit is composed of a first drill bit, a second drill bit, a third drill bit and a fourth drill bit, wherein the diameters of the drill bits becomes smaller gradually. The drill is connected with the first drill bit through threads, the first drill bit is connected with the second drill bit through threads, the second drill bit is connected with the third drill bit through threads, and the third drill bit is connected with the fourth drill bit through threads. The inverted plumb line hole constructing device has the advantages of being flexible in installation, simple in technology and high in reaming speed.
Description
Technical field
The utility model relates to a kind of engineering construction device, particularly a kind of inverted vertical hole construction equipment.
Background technology
Inverted vertical hole is one of important means of dam deformation monitoring.It requires high to the boring hole deviation, allow deviation proportion in 1%.Inverted vertical hole is executed the process that the brill process is actually a control and correction.Traditional job practices generally be creep into-deflection-sealing of hole-cleaning bottom of hole creeps into.The means of control hole deviation also be at rig stability, give the pressure that spouts, rotating speed, drilling tool length and and the concentricity between drilling rod etc. work hard.Most of inverted vertical hole construction is subjected to the restriction in space and place, some anti-oblique measure no practical significance that seems.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of inverted vertical hole construction equipment, and this device is flexible for installation, and the next stage aperture can effectively solve the boring section of deflection as the pilot hole in upper level hole in drilling process, guarantee hole quality.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of inverted vertical hole construction equipment, comprise drilling tool and a cover combination multi-stage reducing drill bit, drilling tool and one makes up the multi-stage reducing drill bit by being threaded, first drill bit, second drill bit, the 3rd drill bit and the 4th drill bit that described combination multi-stage reducing drill bit is diminished gradually by four diameters constitute, between drilling tool and first drill bit, between first drill bit and second drill bit, between second drill bit and the 3rd drill bit, between the 3rd drill bit and the 4th drill bit all by being threaded.
Described drilling tool is diameter 219mm, and wall thickness is the drilling tool of 8mm.
Described first bit diameter is 219mm.
Described second bit diameter is 168mm.
Described the 3rd drill bit is diameter 150mm.
Described the 4th bit diameter is 130mm.
Described first drill bit, second drill bit, the 3rd drill bit and the 4th drill bit are diamond bit.
The inverted vertical hole construction equipment that the utility model provides, owing to adopted the structure of " turriform " drill bit group of being weaved into by multistage diamond bit, use the subdrilling small-bore, the small-bore is as guiding, creep into control large aperture, small-bore again, both economical, but again accelerating construction progress and become the porosity height, advantage such as labour intensity is low and material consumption is few.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of inverted vertical hole construction equipment, a kind of inverted vertical hole construction equipment, comprise drilling tool 1 and a cover combination multi-stage reducing drill bit, drilling tool 1 and one makes up the multi-stage reducing drill bit by being threaded, first drill bit 2 that described combination multi-stage reducing drill bit is diminished gradually by four diameters, second drill bit 3, the 3rd drill bit 4 and the 4th drill bit 5 constitute, between drilling tool 1 and first drill bit 2, between first drill bit 2 and second drill bit 3, between second drill bit 3 and the 3rd drill bit 4, between the 3rd drill bit 4 and the 4th drill bit 5 all by being threaded.The diameter of first drill bit 2, second drill bit 3, the 3rd drill bit 4 and the 4th drill bit 5 is respectively 219mm, 168mm, 150mm and 130mm, is diamond bit.Described drilling tool 1 is diameter 219mm, and wall thickness is the drilling tool of 8mm.
The course of work of the present utility model is as follows: the first step is to make a call to an aperture with the 4th drill bit 5, and the hole deviation of aperture must be in the permissible value scope.Second step was to adopt " turriform " drill bit reaming of being weaved into by multistage diamond bit, up to obtaining qualified inverted vertical hole.
