Abstract
The utility model is mainly applied to post-grouting work in bore cast-in place pile. The new utility model is a scheme coming up with adopting cast-in place pile grouting non-return valve to resolvethe technological problems at present that spraying valve used in post-grouting work in cast-in place pile can't prevent over flowing of cement grout. External structure of cast-in place pile groutingnon-return valve includes valve seat, valve body of division grouting hole, sealing tape of sealed grouting hole and spring seat in the front end of valve body, and internal structure comprises non-return valve consisted of steel balls, spring and stop collar. Non-return valve in the valve body links the valve bottom seal under spring pressure without grout pressure and grouting is carried out smoothly because sealing tape of grouting hole is opened under pressure of grout when non-return valve causes the spring compressed under the pressure of grout and the non-return valve is compressed tothe bottom of the grouting hole. The new utility model has high practicality and reliability in actual application of post-grouting work in bore cast-in place pile.
Description
Technical field
The utility model proposes the slip casting check valve in the drill-pouring post-pressure grouting engineering that is mainly used in tall building, multi-storey building, factory building, the viaduct basis.
Background technique
At present, 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 make the bored pile ultimate bearing capacity of single pile not reach designing requirement, thereby form big 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 bored concrete pile slip casting check valve structure that can overcome described deficiency that proposes.
The utility model is taked following technological scheme in order to address the above problem: bored concrete pile slip casting check valve external structure comprise valve body, the sealing injected hole of valve seat, distribution injected hole sealant tape, be positioned at the spring seat of valve body front end, internal structure comprises check valve, spring, the stop collar that is made of spheroid.Be connected to valve body in the valve seat, front end has with it the spheroid as the interference combination.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.Be placed in the stop collar in the spring spiral and be fixed on the spring seat jointly with spring.Valve body surface is furnished with 2～12, and diameter is 8～20 millimeters a whitewashing aperture.The valve body surface aperture of respectively whitewashing seals with sealant tape.Be provided with spheroid, spring in the valve body chamber, spheroid is not when being subjected to slurries pressure, under the spring pressure effect, be connected with valve base sealing, spheroid makes length of spring compressed at once when being subjected to slurries pressure, the position of spheroid is compressed the bottom that arrives injected hole, and the sealant tape of valve body surface is opened by slurries pressure.The stop collar that is adopted can be controlled the range of check valve, prevents that spring is compressed flexing and lost efficacy under excessive 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, spheroid 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.
