Abstract
The utility model is mainly used for bored pile post grouting engineering and provides a grout spraying valve for bored pile post grouting with a backstop structure, which is designed for solving the technical problem that overflow of cement grout cannot be prevented by a grout spraying valve used in existing bored pile post grouting engineering. An external structure of the grout spraying valve for bored pile post grouting with the backstop structure comprises a valve seat, a valve body, sealing adhesive tapes and a spring seat, wherein the valve body is provided with grouting holes in a distributed mode, the sealing adhesive tapes are used for sealing the grouting holes, and the spring seat is positioned at the front end of the valve body. An internal structure of the grout spraying valve for bored pile post grouting with the backstop structure comprises a spring and the grout spraying valve composed of a frustum cone cylinder. When not under the pressure of grout, the frustum cone cylinder in a cavity of the valve body is connected with the valve seat in a sealed mode under the pressure of the spring; and when the frustum cone cylinder is under the pressure of grout, the spring is compressed, the position of the frustum cone cylinder is compressed to the lower portion of the grouting holes, and the sealing adhesive tapes of the grouting holes are opened by the pressure of the grout so that grouting is preformed smoothly. The grout spraying valve has higher practicality and reliability in practical application.
Description
Technical field
The utility model proposes the drill-pouring post-pressure grouting whitewashing valve in the drill-pouring post-pressure grouting engineering that is mainly used in multi-storey building, tall building, the viaduct basis with check structure.
Background technique
In the bored pile grouting behind shaft or drift lining engineering since the whitewashing valve arrangement unreasonable, cement grout refluxes during use, cause a large amount of wastes, the consequence of cement slurry deficiency at first is the purpose that does not reach expection slip casting, even can cause the bored pile ultimate bearing capacity of single pile not reach designing requirement, thereby form safety or Accident due to quality.
Summary of the invention
The utility model is can not prevent the technical problem that cement grout is excessive in order to solve the whitewashing valve that uses in the present bored concrete pile grouting behind shaft or drift lining engineering, and a kind of a kind of filling pile ' s after grouting whitewashing valve with check structure that can overcome described deficiency that proposes.
The utility model is taked following technological scheme in order to address the above problem: the drill-pouring post-pressure grouting whitewashing valve with check structure comprise the valve body of valve seat, distribution injected hole, sealing injected hole sealant tape, be positioned at the spring seat of valve body front end, internal structure comprises whitewashing valve, the spring with check structure that is made of the frustoconic shape cylinder.Be connected to valve body in the valve seat, front end has with it the frustoconic shape cylinder as the interference combination.Drill-pouring post-pressure grouting whitewashing valve external structure with check structure comprises the sealant tape of valve seat, sealing injected hole, is positioned at the spring seat of valve body front end, the valve body of distribution injected hole, internal structure comprises whitewashing valve, the spring of being made up of the frustoconic shape cylinder, it is characterized in that: insert in the upper end hole of valve body frustoconic shape cylinder upper end, the lower end is a spring, and spring is fixed on valve body lower end.Insert in the upper end hole of valve body the valve seat lower end, keeps valve seat and valve body coaxial, and spring seat is fixed on valve body lower end.Valve body surface is arranged 10, and diameter is 9 millimeters a whitewashing aperture.The valve body surface aperture of respectively whitewashing seals with sealant tape.Be provided with frustoconic shape cylinder, spring in the valve body chamber, the frustoconic shape cylinder is not when being subjected to slurries pressure, under the spring pressure effect, be connected with valve base sealing, the frustoconic shape cylinder makes length of spring compressed at once when being subjected to slurries pressure, the position of frustoconic shape cylinder is compressed the bottom that arrives injected hole, and the sealant tape of valve body surface is opened by slurries pressure.
The utility model beneficial effect and advantage are: promptly stop slip casting after the quantity delivered of drilled pile grouting behind shaft or drift lining slurries in pile body reaches designing requirement, the body internal pressure reduces suddenly, the frustoconic shape cylinder is got back to original position rapidly under the spring pressure effect, the slip casting pore is sealed again, form the check structure, thereby near the cement grout of assembling the valve body can't be refluxed.The utility model has advantages of high practicability and reliability in the engineering practical application, can guarantee the actual effect of bored pile slip casting.
Description of drawings
Fig. 1 is the example structure generalized section
Number in the figure: 1 valve seat, 2 frustoconic shape cylinders, 3 springs, 4 gunniting holes, 5 sealant tapes, 6 valve bodies, 7 spring seats.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Embodiment as shown in Figure 1, shotcrete pipe is by valve seat 1, the valve body 6 of distribution gunniting hole 4, the sealant tape 5 of valve body 6 each injected hole of surface sealing and the spring seat 7 of valve body lower end are formed, it is fixing that the interior also welding of upper end hole of valve body 6 is inserted in valve seat 1 lower end, keep valve seat 1 and valve body 6 coaxial, the front port that is arranged in the valve seat 1 of valve body 6 is provided with the frustoconic shape cylinder 2 that engages with valve seat 1 interference, it engages best results, spring 3 is positioned at the tube chamber of valve body 6, the position is in the middle of frustoconic shape cylinder 2 and spring seat 7, keep spring 3 to be in pressured state, so that frustoconic shape cylinder 2 and valve seat 1 are in sealing state, spring seat 7 is fixed on the lower end of valve body 6, as the pedestal of frustoconic shape cylinder 2 and spring 3, valve body 6 surface arrangement gunniting holes 4 also use sealant tape 5 to twine a few maintenance sealings.
