Abstract
The invention discloses a single-pipe diverter for high-pressure jet grouting and relates to a diverter part for the high-pressure jet grouting. The single-pipe diverter comprises an upper casing, a lower casing and a hollow shaft, wherein the hollow shaft is arranged in the lower casing in a rotating way; one end of the hollow shaft extends out from an opening formed in the bottom of the lower casing and then is connected with a core tube of a drill rod; a bearing cap is arranged inside the lower casing around the hollow shaft; a bearing for supporting the hollow shaft in a rotating way is arranged on the bearing cap; a bayonet coupling for being connected with a high-pressure hose is formed in the side part of the upper casing by being perpendicular to the axial direction of the hollow shaft; the bayonet coupling is communicated with an axial channel of the hollow shaft through a slurry channel arranged inside the upper casing to form a grouting channel communicated to the core tube of the drill rod; a handle which is used for hanging a lifting hook, so the diverter can be hung on a drill tower, is arranged on the upper casing. According to the single-pipe diverter disclosed by the invention, liquid in a high-pressure transportation pump hose can be smoothly imported into the core tube of the drill rod, and smooth importation of the liquid and drilling of the drill rod are guaranteed.
Description
Technical field
The present invention relates to construction project stiffening basic ground field, in order to the mud in high-pressure hose to be imported to the air deflector in drilling rod in enforcement high pressure jet grouting, be specially high pressure jet grouting single pipes for flow guide device.
Background technology
Jet grounting is the common method of construction project stiffening basic ground, after it utilizes rig that the Grouting Pipe with nozzle is pierced or be incorporated into the predetermined degree of depth of soil layer, with the pressure of 20-40Mpa, slurries or water are ejected from nozzle, form the space of injection stream impact failure soil layer and predetermined shape, when energy is large, when the power of the fast and arterial injection stream of speed is greater than soil layer construction intensity, soil particle just peels off from soil layer, part fine grained soils to be emerged ground with slurries or water, all the other grogs are in the impact force of jet, under the effect such as centrifugal force and gravity, mix with slurry agitation, and in certain puddled soil ratio and quality size, rearrange regularly.The mixing of the part swept away soil is formed reinforcing body by the slurries of such injection, thus reaches the object of soil mass consolidation.High pressure jet grouting can increase foundation strength, raising bearing capacity of foundation soil, sealing antiseepage, reduces a soil pressure working as structure, prevent the multi-functionals such as sand liquefaction.
High pressure jet grouting single pipes for flow guide device is the connection transfer device connecting high pressure pumping flexible pipe and drilling rod core pipe, its be slurries water conservancy diversion that high-pressure pump is sent here by high-pressure hose to core pipe, slurries again by the nozzle bottom drilling rod to form high-pressure spray.Its top connects high pressure pumping flexible pipe, and bottom jointed rod core pipe, comprises fixed part and rotate the rotation section of creeping into drilling rod.
Summary of the invention
The object of this invention is to provide a kind of high pressure jet grouting single pipes for flow guide device, the liquid in high-pressure delivery pump hose can import in the core pipe of drilling rod by smoothly, ensures the smooth importing of liquid and creeping into of drilling rod.
For achieving the above object, technical scheme of the present invention is: a kind of high pressure jet grouting single pipes for flow guide device, comprise upper shell, lower house and hollow shaft, hollow shaft is rotated and is arranged in lower house, be connected with drilling rod core pipe after the opening that its one end is arranged bottom lower house stretches out, lower house inside is provided with bearing cover around described hollow shaft, bearing cover is provided with the bearing for hollow shaft described in rotational support, the sidepiece of described upper shell is axially arranged with the bayonet coupling for connecting high-pressure hose perpendicular to hollow shaft, the slurry channels that bayonet coupling is arranged by upper shell inside is connected with the axial passage of hollow shaft, form the slip casting passage leading to drilling rod core pipe, upper shell is provided with hangs the bale handle on boring tower for mounting suspension hook to make air deflector.
Beneficial effect: the hollow shaft that the present invention is arranged by its inner rotation is to be connected with the core pipe of drilling rod, and can rotate with the rotation of drilling rod, and deliver to drilling rod core pipe by the slurries that high-pressure hose transports by bayonet coupling that upper shell is arranged and the slurry channels of inside thereof and the axial passage of hollow shaft, ensure that the smooth importing of slurries and creeping into of drilling rod.
