Description
Technical Field
The utility model belongs to the technical field of bridge engineering technique and specifically relates to a bored pile boulder fisher.
Background
The cast-in-situ bored pile often touches boulders in the process of drilling construction, can salvage through the manual work when drilling depth is less usually, will change the rig when being darker, adopts other modes such as percussion drill to drill. The manual salvage is only suitable for within 2m, the manual underground salvage with the depth exceeding 2m is extremely dangerous, if the manual salvage is not suitable, only the drill can be replaced to become the percussion drill, and meanwhile, the drill operator is also replaced, and the percussion drill has lower efficiency than that of a positive and negative circulation rotary drilling machine.
Disclosure of Invention
The utility model aims at providing a bored concrete pile boulder fisher according to the not enough of above-mentioned prior art, it is rotatory to have annular wire rope's fisher through the power device drive, makes boulder can be saved inside the pipe shaft of fisher, overcomes bored concrete pile and creeps into the in-process and meet secret boulder, is difficult to salvage, needs to change the problem of drilling mode, change drilling equipment even.
The utility model discloses the purpose is realized accomplishing by following technical scheme:
the utility model provides a bored pile boulder fisher which characterized in that: the pipe comprises a pipe body and a pipe shaft, wherein the pipe shaft is arranged above the pipe body and fixedly connected with the pipe body, a connecting sleeve for externally connecting a power device is arranged at the top of the pipe shaft, an opening is formed in the bottom of the pipe body, an annular steel wire rope is arranged at the position of the opening in a spiral mode, and a drill bit is arranged at the bottom of the pipe body.
The middle part of the annular steel wire rope arranged in a spiral shape is provided with a circular opening. One side of the pipe body is provided with a stone taking port.
The connecting sleeve is externally connected with a rotating power device.
And a stiffening plate is arranged between the pipe body and the pipe shaft.
The drill bits are uniformly and symmetrically arranged along the circumferential direction of the pipe body.
The utility model has the advantages that: 1) manual fishing in the orifice is avoided, and safety risks are greatly reduced; 2) mechanical equipment is prevented from being replaced, timely salvage is achieved, and labor is reduced; 3) the manufacturing is simple and the manufacturing cost is economical; 4) the fisher is directly connected to the drill rod, and the stone can be salvaged by normally starting the drilling machine, so that the method is simple and easy to implement.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a plan view of the middle tube body of the present invention.
Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, the labels 1-9 in the figures are respectively expressed as: the pipe comprises a sleeve 1, a pipe shaft 2, a pipe body 3, a stone taking port 4, an annular steel wire rope 5, a drill bit 6, a drill rod 7, a stiffening plate 8 and a drill carriage 9.
Example (b): the drilled pile boulder fisher in the embodiment is used for fishing boulders encountered in drilling construction of the drilled pile, and a drilling machine does not need to be replaced.
As shown in fig. 1, the borehole pile solitary stone fisher in the present embodiment includes: the pipe comprises a sleeve 1, a pipe shaft 2 and a pipe body 3, wherein the pipe shaft 2 and the pipe body 3 are connected and fixed to form a whole, and the diameter of the pipe body 3 is the same as that of the drilling pile; the sleeve 1 is fixed on the top of the tubular shaft 2 for externally connecting power. As shown in fig. 1, the power device in this embodiment is a drilling machine as a rotary power device, and the fisher can rotate downwards under the driving of the drilling machine and realize the fishing of the solitary stone. The drill body is arranged on the drill carriage 9, which facilitates movement in a construction site. The drilling machine is provided with a drill rod 7, the drill rod 7 can be connected and fixed with the sleeve 1 in a matching mode, namely the sleeve 1 is provided with a connecting structure matched with a conventional drilling machine, and therefore power output by the drilling machine can be effectively transmitted to the fisher.
Referring to fig. 1 and 2, the bottom of the pipe body 3 is open, and a spiral annular steel wire rope 5 is disposed at the open position, and a circular opening is formed in the middle of the annular steel wire rope 5; when the pipe body 3 is driven by the drilling machine to rotate downwards to meet the boulder, the annular steel wire rope 5 can be pressed and expanded along the spiral direction under the extrusion action of the boulder, so that the circular opening is gradually pressed and expanded until the boulder is extruded into the pipe body 3. After the extrusion of the boulder is finished, the boulder is positioned in the pipe body 3, and the annular steel wire rope 5 recovers the position of the boulder, namely the initial size of the circular opening in the recovery period, so that the boulder is blocked by the annular steel wire rope 5 when lifted upwards, and is prevented from falling out of the pipe body 3 again; and then the drill rod 7 is lifted by the drilling machine, the fisher returns to the ground, and the boulder is manually taken out from the boulder taking port 4 on the pipe body 3, so that the boulder is salvaged.
As shown in figure 1, drill bits 6 are uniformly and symmetrically arranged at the bottom of the pipe body 3 along the circumferential direction of the pipe body, and the drill bits 6 are used for cutting soil, drilling downwards and extruding boulders.
In the embodiment, in specific implementation: the pipe body 3 can be a thin-wall structure, in order to strengthen the integral rigidity of the pipe shaft 2 and the pipe body 3, the connecting surface of the pipe shaft 2 and the pipe body 3 is provided with a stiffening plate 8, and the stiffening plate 8 can be uniformly and symmetrically arranged along the circumferential directions of the pipe shaft 2 and the pipe body 3.
The diameter of the pipe body 3 is equal to that of the drilled pile, so that the diameter of the boulder in the drilled hole of the drilled pile is generally smaller than that of the pipe body 3, and therefore the boulder can be salvaged; however, when the diameter of the boulder is larger than that of the pipe body 3, it is considered that the boulder is broken by the impact of the impact drill in advance, and then the fisher in the embodiment is used for fishing the boulder.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
