In the scheme, the method comprises the following steps: the exhaust pipe is tightly attached to the inner wall of the steel pipe, so that air can be conveniently exhausted when the exhaust pipe needs to be obliquely inserted into the hole.

In the scheme, the method comprises the following steps: the steel pipe and advance to be connected through the screw thread is dismantled between the thick liquid pipe, and the dismouting is rapid, can pull down it and clear up.

In the scheme, the method comprises the following steps: the slurry inlet pipe and the exhaust elbow are integrally formed, the structure is stable, gaps are reduced, and air is prevented from entering or slurry flows out.

In the scheme, the method comprises the following steps: the nut, the pressing sleeve, the anti-falling head and the adjacent two of the plurality of rubber sealing rings are all provided with gaskets, and the durability is improved.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: simple structure, the equipment is convenient, bears the slip casting pressure height to improve downthehole slip casting's speed when guaranteeing the slip casting quality. The exhaust elbow that sets up can be with downthehole air escape to after air escape finishes, close through the ball valve, with guarantee slip casting pressure, simple structure, easy operation. The exhaust pipe is arranged to extend out of the steel pipe, so that the exhaust pipe can be ensured to penetrate into the bottom of the hole to exhaust air as far as possible. The slurry inlet pipe and the exhaust elbow can be detached and separated from the steel pipe and the exhaust pipe as a whole, so that the slurry inlet pipe and the exhaust elbow can be cleaned conveniently, and the slurry inlet pipe and the exhaust elbow are prevented from being blocked by residual concrete in the slurry inlet pipe and the exhaust elbow during subsequent use to influence slurry injection or exhaust.

Drawings

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

fig. 1 is a cross-sectional view of the present invention;

fig. 2 is a perspective view of the present invention;

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 3, the grouting mechanical sealing plug joint device comprises a steel pipe 9, wherein a nut, a pressing sleeve 4 and a plurality of rubber sealing rings 6 are sequentially sleeved outside the steel pipe 9 from the beginning to the end. The nut is in threaded connection with the steel pipe 9, and the two sides of the nut are provided with wrenches 8 convenient to rotate. The tail end of the steel pipe 9 is convexly provided with a circle of anti-falling heads for the rubber sealing ring 6 to lean against. Preferably, a gasket 7 is padded between two adjacent nuts, the pressing sleeve 4, the anti-falling head and the plurality of rubber sealing rings 6, so that the durability is improved.

The beginning of steel pipe 9 can be dismantled through the screw and be connected with into thick liquid pipe 1, and the dismouting is rapid, can pull down into thick liquid pipe 1 and clear up. The other end of the grout inlet pipe 1 is provided with external threads for being connected with a grouting pipe on the grouting trolley. An L-shaped exhaust elbow 2 is fixedly arranged on the slurry inlet pipe 1, and one end of the exhaust elbow 2 extends into the slurry inlet pipe 1 and bends towards the tail end of the steel pipe 9. The other end of the exhaust elbow 2 is left outside the slurry inlet pipe 1 and is provided with a ball valve 3. Preferably, the slurry inlet pipe 1 and the exhaust elbow 2 are integrally formed, so that the structure is stable, the gap is reduced, and air is prevented from entering or slurry is prevented from flowing out. Still be equipped with blast pipe 5 in the steel pipe 9, the one end of blast pipe 5 is connected with the inner of exhaust elbow 2, and blast pipe 5 is arranged in steel pipe 9, and outside steel pipe 9 was stretched to the other end of blast pipe 5, stretched and can insert the hole bottom outside steel pipe 9, the air escape of being convenient for. Preferably, the inner end of the exhaust elbow 2 is closely attached to the inner wall of the steel pipe 9, so that the exhaust pipe 5 is closely attached to the inner wall of the steel pipe 9, and when the exhaust pipe needs to be obliquely inserted into the hole, air can be conveniently exhausted.

During the use, the rotatory spanner 8 drives the nut and moves down, through pressing sleeve 4 with the effort in rubber ring 6, makes its inflation to it is closely knit to pack the clearance between shutoff and the pore wall, does not leak thick liquid. And starting grouting operation, closing the ball valve 3 to seal the exhaust elbow 2 when slurry is discharged from the outlet end of the ball valve 3, and performing pressure-maintaining grouting until the grouting operation is completed.

When the grouting hole is an obliquely upward or parallel hole, the exhaust pipe 5 with a proper hole diameter is connected with the exhaust elbow 2, the slurry inlet pipe 1 is connected with the steel pipe 9, air in the hole can be upwards extruded by slurry in the direction of the grouting hole opening in the grouting process, and then the air in the hole is discharged through the exhaust pipe 5 inserted into the bottom of the hole. And when the slip casting hole is darker, can splice a section extension pipe in the length of blast pipe 5 to satisfy and insert blast pipe 5 to the hole bottom in the slip casting hole, all discharge the downthehole air.

When the slip casting hole is the downward hole of slope, will not adopt blast pipe 5, directly will advance thick liquid pipe 1 and be connected with steel pipe 9, when thick liquid flow direction hole bottom, the air flows towards the slip casting mouth direction naturally, then directly discharges the downthehole air of slip casting through exhaust elbow 2.

After grouting is finished, the force acting on the rubber sealing ring 6 is released through the reverse rotation wrench 8, the sealing ring 6 is restored to the original appearance, the steel pipe 9 is taken out, the slurry inlet pipe 1 and the exhaust pipe 5 are disassembled, and the slurry inlet pipe 1 and the exhaust elbow 2 are cleaned for subsequent use.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
