Description
Technical field
The utility model is related to Construction Technology fields, more specifically, are related to a kind of going for cast-in-situ bored pile hole wall
Mudcake device.
Background technology
Bored concrete pile is the pile foundation structure that the buildings such as house, bridge, water conservancy dam generally use.Existing cast-in-situ bored pile
Construction method be：First, measurement and positioning buries steel pile casting, then middle drill bit is started drilling machine and tunneled downwards in steel pile casting
Pore-forming well, after stake holes is formed, first time borehole cleaning；Then it is put into steel reinforcement cage in stake holes, after the completion of steel reinforcement cage, second of borehole cleaning；
Conduit is placed in steel reinforcement cage later, concrete funnel is installed, then the first batch of concrete of Reperfu- sion controls concrete pouring height by lining rope, tears open
Except conduit is up to the elevation of concrete pouring to design requirement；Pile crown laitance layer thickness is normally controlled in 0.5-1m, extracts casing, construction
It completes.
The construction method of above-mentioned cast-in-situ bored pile is primarily present following disadvantage：First, in drilled pile pore forming process,
Carry out mud off.If without mud off, drill around the soil body will collapse hole fall into stake holes, it is therefore necessary to
Mud off is used to form mudcake on stake holes wall.Mudcake exists always during pile foundation concrete pouring, and concrete and stake has been isolated
The consolidation of surrounding soil affects the bearing capacity of pile foundation, reduces the service life of pile foundation；Second, steel reinforcement cage is during the installation process
It is possible that smearing hole wall, it is stained with soil on steel reinforcement cage, reduces the quality of stake；Third, friction pile are possible to because of Lack of support
And post jacking measure must be used.Post-mud-jacking bored pile is not only of high cost, larger mixed with the usage amount of additive cement mortar, Er Qieqi
The effect for improving the bearing capacity of friction pile is little, can also cause the waste of raw material.
Utility model content
In view of the above problems, the purpose of this utility model is to provide one kind and removing mudcake device, to solve prior art drilling
Bored concrete pile influences pouring pile bearing capacity because of there are problems that for mudcake.
To achieve the goals above, the present invention is realized by technical solution below：
One kind removing mudcake device, including interior tube body and the outer shroud tube body being arranged outside said inner tube body, the outer endless tube
There is a closed cavity, the cavity to be connect with high-pressure hydraulic pump by water pipe, the outer wall upper edge week of the outer shroud tube body on body
To multiple nozzles are provided with, the multiple nozzle is connected to the cavity.
Preferably, the outer shroud tube body is connect with said inner tube body by multigroup reinforcing rib group, reinforcing rib described in every group
Group includes two symmetrically set reinforcing rib.
Preferably, the multiple nozzle be set in qually spaced on the outer shroud tube body and the nozzle be bore by it is interior extremely
Outer gradually increased horn-like nozzle.
Preferably, it is symmetrically provided with multigroup hanging ring group on the lateral surface of the outer shroud tube body, hanging ring group described in every group
Including two symmetrically arranged hanging rings.
Preferably, more water pipes are provided in the cavity, the more water pipes are along the circumferential equidistant of the cavity
Setting.
Compared with prior art, the utility model at least has the advantages that：The utility model removes mudcake device
Mudcake on pile foundation hole wall can be rinsed out, rinse the mudcake got off and be discharged as the concrete face of rising rises at the top of pile foundation hole,
This allows for periphery of pile foundation and cures combinations well with pile foundation hole wall soil loading body, substantially increase entire friction pile and the soil body it
Between frictional resistance, reduce or eliminate the sedimentation of pile foundation in the future, improve the durability of pile foundation structure object structure；The present invention
Pile foundation obtained cures well with pile foundation surrounding soil in conjunction with well-set entirety is formed as, this allows for the carrying of pile foundation
Power has obtained greatly being promoted, and reduces the transversely deforming and linear deformation of pile foundation, greatly improves the service life of pile foundation,
And the bearing power increase of the pile foundation of the bigger method preparation with the present invention of diameter of pile foundation is bigger.
Description of the drawings
By reference to the description below in conjunction with attached drawing, and with the utility model is more fully understood, this reality
It will be more clearly understood and understood with novel other purposes and result.In the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Identical label indicates similar or corresponding feature or function in all the appended drawings.
Specific implementation mode
Specific embodiment of the utility model is described in detail below with reference to attached drawing.
Go mudcake device, including interior tube body 101 and setting in interior tube body 101 as shown in Figure 1, the utility model provides one kind
External outer shroud tube body 102.Outer shroud tube body 102 includes inner ring pipeline and the outer shroud pipeline being arranged outside interior endless tube road, interior endless tube
The both ends in road between interior endless tube road and inner ring pipeline respectively with the connection closed at both ends of outer shroud pipeline to form a closed sky
Chamber 103.Interior tube body 101 is connect with outer shroud tube body 102 by multigroup reinforcing rib group, and every group of reinforcing rib group includes two and be symmetrical arranged
Reinforcing rib 104, in the present embodiment, which can be made of reinforcing bar, i.e., by one end of reinforcing bar and outer shroud tube body 102
The inner wall of inner ring pipeline weld together, the other end outer wall corresponding on interior tube body 101 of reinforcing bar welds together.Cavity
High pressure resistant water pipe 105 is provided in 103, high pressure resistant water pipe 105 is stretched to from 103 top of cavity in cavity 103, high pressure resistant water pipe
105 connect with high-pressure hydraulic pump.In actual use, can more high pressure resistant water pipes 105 be set according to Pile Diameter size, it is more
Circumferential spaced set of the high pressure resistant water pipe 105 of root along cavity 103.The outer tube wall upper edge of outer shroud tube body 102 is circumferentially provided with more
A nozzle 106, the spaced set on outer tube body 101 of multiple nozzles 106, multiple nozzles 106 are connected to cavity 103.In order to make
The area bigger for the water column radiation that each nozzle 106 sprays is obtained, nozzle 106 is set as bore gradual increased loudspeaker from the inside to the outside
Shape nozzle.Multigroup hanging ring group is additionally provided on the top surface of outer tube body 102, every group of hanging ring group includes two symmetrically arranged hanging rings
107.Multigroup hanging ring group is connect by steel wire rope with boom hoisting to facilitate boom hoisting that mudcake device will gone to sling rising
