Abstract
The invention discloses a kind of drilling tool, belong to technical field of engineering machinery.Described the device including drill pipe, drill pipe front-end triangular diamond plate is fixed.This drilling tool can reach the requirement of pump pressure in pipe concrete continuous pile forming method.
Description
Technical field
The invention belongs to technical field of engineering machinery, be specifically related to a kind of drilling tool.
Background technology
Pump pressure in pipe concrete continuous pile forming method (being called for short post-set reinforcing cage technique) is the technology of a kind of advanced person in building operations.After this technique needs drilling tool to bore stake holes, when brill carried by drilling tool, need fluid concrete simultaneously, when drilling tool is extracted completely, pouring concrete is complete, finally before concrete formation, inserts reinforcing cage.This technique can reduce construction cost greatly, provides efficiency of construction.
Existing simple drill is also not special for pump pressure in pipe concrete continuous pile forming method, and simple drill mostly is conveyor screw shape, can not reach the requirement of pump pressure in pipe concrete continuous pile forming method.
Summary of the invention
The object of the invention is solve the problem and provide a kind of drilling tool.This drilling tool can reach the requirement of pump pressure in pipe concrete continuous pile forming method.
The technical solution adopted in the present invention is:
Described a kind of drilling tools, including drill pipe, drill pipe front-end triangular diamond plate is fixed.
Further, as described in triangular diamond plate front fixed a bit.
Further, as described in central triangular diamond plate is fixed with a door cover.
Further, as described in triangular diamond plate fixed on both sides have wear-resisting layer.
Bit selection, stated it is triangular diamond plate by means of welding the front end.
Optimization, described the door cover fixed by means of welding in the triangular diamond plate in the middle.
Optimization, wear-resisting layer fixed by means of welding described in triangular diamond plate on both sides.
Optimization, described in the triangular diamond plate material is Q235 steel.
The present invention has the following advantages:
(1) this device can reach the requirement of pump pressure in pipe concrete continuous pile forming method;
(2) this apparatus structure is simple, and result of use is good, long service life, and construction costs is low, and sedimentation is little, and effect is high;
(3) the front end of the triangular diamond plate fixed in this device has a bit, has the very good into the rock function;
(4) be provided with door closure in this device, when drilling tool creeps into, door closure is closed, and can prevent rock from entering drilling rod like this, when brill carried by drilling tool, door closure is opened naturally, can better allow concrete enter stake holes.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is further detailed explanation.
The structural representation of a kind of drilling tool that Fig. 1 provides for the embodiment of the present invention 1.
Detailed description of the invention
Embodiment 1
Refer to figure 1, a kind of tool 1 including drill pipe, drill pipe 1 front welding have triangular diamond plate 2, triangular diamond material is Q235 steel plate 2.Triangular diamond plate 2 front end welding have more than one bit.Central triangular diamond plate 2 welding with a door cover 5.Triangular diamond plate is drill pipe 1 and 2 bit 3 unit, gate lid 5 the connection of the body, and it is the main bearer of cutting force.Ground is cut in the effect of drill bit 3, and drilling tool is constantly crept into downwards.2 on both sides of the triangular diamond plate welding have wear-resisting layer 4, wear-resisting layer 4 can reduce drilling tool wear and improve the durability of drilling tools.
When this device works, drilling tool bores stake holes, and door closure 5 is closed, and prevents ground from entering drilling rod 1.After stake holes is bored, when brill carried by drilling tool, the mixed earth of cast, now door closure 5 is opened, and door closure 5 is the same as a umbrella, better allows concrete flow into stake holes.When drilling tool is extracted completely time, concrete is also poured, and inserts reinforcing cage before finally shaping in concrete.
Embodiment 2
In this example and implementation example 1, triangular diamond plate welding bit 3 the front end of the no. 2Triangular diamond plate for 2 separate cutting body, but the implementation example of drilling tool into rock the effect not beautiful.
It should be noted last that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
Claims (4)
