Abstract
The utility model discloses a kind of cylinder brill salvaged for boulder in pile foundation construction, include the cylindrical tube of under shed structure, it is coaxial on the cylindrical tube on be fixed with the fittings body being connected with drilling rod；It is provided with the fishing net being made of steel wire rope in cylindrical tube under shed, multiple openings for having brill tooth, offering for gas and water discharge on cylindrical tube body sidewall are uniformly fixed at cylindrical tube under shed edge.The utility model advantage is to aim at convolution drilling machine pile foundation construction and design.When encountering underground in drilling process of constructing and having boulder or other hard objects, it drives cylinder to bore by the drilling machine that circles round to salvage boulder and hard objects except stake holes, not only greatly improve work efficiency, and save and arrive bottom hole fishing under salvage person, eliminate the insecurity of fishing.
Description
Technical field
The utility model is related to river Bridge Pile Foundation Construction, it is especially for the cylinder that boulder is salvaged in pile foundation construction
It bores.
Background technology
In river bridge construction, for the river that geological condition is poor, such as all fine sands in riverbed, Extra-fine sand, simultaneously
It is influenced by the go around factors such as changeable and scouring intensity is big of river so that bore operation risk is high, difficulty of construction is big；Above-mentioned
Under the conditions of matter, pile foundation construction mostly uses convolution drilling machine.But for the needs of flood control, usually building has flood control control island in river,
To prevent river water from washing away control island, He Wu departments are required for filling a large amount of slabstones every year, cause Below The River Bed deposit a large amount of boulder,
Cobble；Therefore it in pile foundation construction, when convolution drilling machine encounters underground in drilling process and has boulder or other hard objects, will lead
Cause convolution drilling machine that can not creep into.To solve the problems, such as this, current method is dived beneath the water salvaging by manually dressing diving dress, this is not
Only working efficiency is low and schedule delays, exists simultaneously the security risk of salvage person.
Invention content
The utility model aim is to provide a kind of cylinder brill salvaged for boulder in pile foundation construction.
To achieve the above object, the utility model takes following technical proposals：
The cylinder described in the utility model salvaged for boulder in pile foundation construction bores, and includes the cylindrical tube of under shed structure
Body, it is coaxial on the cylindrical tube on be fixed with the fittings body being connected with drilling rod；Setting in cylindrical tube under shed
Have the fishing net being made of steel wire rope, cylindrical tube under shed edge uniformly fix it is multiple have brill tooth, be located at cylindrical tube
The opening for gas and water discharge is offered on body sidewall.
The fishing net is lived by least two supporting steel-cables and Duo Gen along cylindrical tube interval between diameters arrangement
Dynamic steel wire rope；The both ends of the every supporting steel-cable are fixedly connected with cylindrical tube body sidewall respectively；The every movable steel
One end of cord is fixedly connected with cylindrical tube body sidewall respectively and the other end vacantly rides on supporting steel-cable, movable steel cord
Length be more than cylindrical tube radius.
The fixing end and free end of more movable steel cords are arranged in a crossed manner, the free end difference of every movable steel cord
It is banded with steel tied silk.
Reinforcing ring is welded on the cylindrical tube under shed peripheral surface, multiple brill teeth are uniformly welded on
On the reinforcing ring.
The utility model advantage is to aim at convolution drilling machine pile foundation construction and design.When encountering underground in drilling process of constructing
When having boulder or other hard objects, drives cylinder to bore by the drilling machine that circles round and salvage boulder and hard objects except stake holes, no
It only greatly improves work efficiency, and saves and arrive bottom hole fishing under salvage person, eliminate the dangerous of fishing
Factor.
Description of the drawings
Fig. 1 is the present invention looks up structural representation that cylinder described in the utility model bores.
Fig. 2 is the vertical profile structural schematic diagram that cylinder described in the utility model bores（Fishing net is concealed in figure）.
Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
The utility model is existing to be described with the stake holes of a diameter of 200cm：
As shown in Figure 1, 2, the cylinder described in the utility model salvaged for boulder in pile foundation construction bores, including under shed structure
Cylindrical tube 1, it is coaxial on the roof of cylinder 1 on be fixed with fittings body 2 for being connected with convolution borer drill rod, cylinder
Body 1 is process by the steel plate that thickness is 2cm, 1 internal diameter 160cm of cylinder, the high 180cm of cylinder, and two are symmetrically offered on 1 side wall of cylinder
A 10cm circular opens 3 for discharging gas and water；It is welded with reinforcing ring 4 on 1 under shed peripheral surface of cylinder, is added
4 high 30cm of strong ring, is made of thickness of 2cm steel plates；Four brill teeth 5 are uniformly welded on reinforcing ring 4 vertically downward, each bore tooth
5 material is hard alloy, bores length × width × height=3.8 × 3.8 × 7.9cm of tooth；It is to protect that 4 purpose of reinforcing ring, which is arranged,
The rigidity and intensity for demonstrate,proving cylinder lip angle also ensure the fastness for boring tooth 5 in this way.
Away from being provided with fishing net at the 15cm of under shed top in cylinder 1, fishing net by a diameter of 4.2cm of 20 six roots of sensation height
Strong steel wire rope is along 1 uniform diameter arranged for interval of cylinder；Wherein two rope capacities are 165cm, both ends respectively with 1 side wall of cylinder
It is welded and fixed and constitutes supporting steel-cable 6；One end of remaining 24 steel wire ropes is welded and fixed with cylinder lateral wall and another respectively
End vacantly rides over and constitutes movable steel cord 7 on the rope of supporting steel wire 6；The fixing end and free end of every movable steel cord 7 are along cylinder 1
The length of circumferentially-spaced arranged crosswise, every movable steel cord 7 is 100cm, and the free end of every movable steel cord 7 is bound respectively
There is steel tied silk to scatter to prevent not-go-end head.
Utility model works principle is summarized as follows：
When convolution drilling machine encounters underground lonestone, cobble or other hard objects in drilling process, causes drilling machine that can not bore
Into when, operation convolution drilling machine proposes drill bit, changes cylinder described in the utility model and bores, and then operation convolution drilling machine driving cylinder bores rotation
Turn to lower pressure；
When the fishing net in cylinder brill touches bottom boulder, cobble in pile foundation hole, rotation downward pressure effect is bored in cylinder
Under, using 7 toughness of movable steel cord of fishing net, fishing net generates flexible deformation and is softened, and boulder, cobble, which enter, to be beaten
In dredger；
When operation convolution drilling machine enhancing tube bores, movable steel cord 7 restores flexible deformation under the rigidity effect of its own
Cylinder is bored lower mouth to block, to salvage to come out of pile foundation hole by boulder, cobble or hard objects.
When boulder, cobble are more in pile foundation hole, repeat the above process until boulder, cobble in pile foundation hole are all dragged for
Go out.
