Description

Device for secondary grouting repair of grouting sleeve

Technical Field

The utility model relates to a secondary mends cementer especially relates to a device that is used for grout sleeve secondary to mend grout.

Background

In the built prefabricated concrete structure house, the grouting surface in the grouting sleeve is not full or fails to meet the design requirements due to construction reasons (such as insufficient grouting pressure, slurry leakage or slurry leakage, and the like), and the reliability of the prefabricated concrete structure house is affected.

Because the grouting material filled in the grouting sleeve for the first time reaches an initial setting state or a final setting state, and the grouting hole of the grouting sleeve is blocked, the grouting can be only selected from the grout outlet hole during secondary grouting, so that an air outlet needs to be arranged in the grouting process, and otherwise, the secondary grouting is difficult to achieve compactness and reliability.

In order to solve the problem of secondary grout filling, the prior art has different solutions, for example, patent 201820989169.8 discloses a grout filling device for a grout sleeve, which comprises a grout sleeve, a steel bar extending from the grout sleeve, the steel bar being matched with threads on the inner wall of the grout sleeve, a grout outlet being provided above the side surface of the grout sleeve, a grout injection port being provided below the side surface of the grout sleeve, the grout outlet being connected to a grout filling funnel through a right-angle pipeline, the grout filling funnel being filled with grout of the same material as that in the grout sleeve, and an exhaust lead wire being further provided in the grout filled in the grout filling funnel; so that whether the grouting is compact or not and whether air bubbles exist or not can be determined; simultaneously, grout supplementing operation is synchronously performed under the condition that grouting is judged to be not compact, so that the grouting material is compact and full. The above method has its advantages, but it requires additional opening on the grout sleeve to supplement the grout funnel, which is difficult to operate in reality, and the grout flows in the funnel by itself, such as in the grout sleeve, without pressure, and is easily blocked, and in addition, the additional opening on the grout sleeve to supplement the grout funnel increases the manufacturing cost of the sleeve.

In addition, 200720184302.4 discloses a grouter with good joint filling quality, high compactness and convenient construction. The novel mortar outlet device comprises a barrel, wherein a piston is arranged in the barrel and comprises a plurality of sealing rings, the sealing rings and the inner periphery of the barrel are hermetically sealed, a pull rod is arranged in the middle of the piston, a handle is arranged at the other end of the pull rod, a rear cover is arranged on the barrel and on the same side of the handle, the pull rod penetrates through the center of the rear cover, a mortar outlet is formed in the other end of the barrel, and the lower end of the mortar outlet is wedge-shaped. The utility model is suitable for a building is caulked. The device is not a secondary grout supplementing device for the grouting sleeve, and in addition, the other end of the grouting sleeve is provided with a grout outlet, so that the manufacturing cost of the sleeve is increased.

In the practical technology, the sleeve grouting in the fabricated concrete structure is mainly performed by pressurizing and grouting by a pressure grouting machine (or a grouting device or a grouting gun), and the pressure grouting machine has two modes of electric grouting and manual grouting. However, no matter the electric grouting machine or the manual grouting machine (or the grouting device or the grouting gun) is adopted, the grouting hole of the grouting sleeve is small, the grouting hole of the grouting sleeve can be filled by the grouting device (or the grouting gun), and no air outlet exists during secondary grouting, so that the secondary grouting is difficult to realize.

Therefore, the utility model provides a one set of secondary mends cementer can carry out the secondary to the not full part of grout sleeve after the grout material solidifies.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of prior art, the utility model provides a one set of grout sleeve thick liquid face is not fuller secondary mends cementer in to the prefabricated concrete structure of having built, utilizes the device can mend thick liquid to the part that grout sleeve thick liquid face is not fuller in the prefabricated concrete structure of having built to reach the full requirement of thick liquid face in the grout sleeve. The device has simple structure and easy operation, and the joint has simple structure and easy operation, and can not block the slurry outlet.

In order to realize the purpose of the utility model, the technical proposal of the utility model is that:

the utility model provides a device for grout sleeve secondary mends grout, is including the joint that is used for the grout, with articulate's slip casting device, the joint that is used for the grout is inside hollow straight tube, and the pipe diameter is 7mm-9mm, and the pipe wall is 0.5mm-2mm, the slip casting device includes grouter, grouting gun and feeder, the joint lug connection that is used for the grout is in the exit of slip casting device.

Compared with the prior art, the utility model has the advantages that:

1. the utility model relates to a device for grout sleeve secondary mends grout is inside hollow siphonozooid, carries out specific design to its pipe diameter and pipe wall, can be fine and go out the grout mouthful link up, forms a natural air outlet channel, lets the air outflow when mending the grout, realizes grouting smoothly.

2. The utility model discloses a device for grout sleeve secondary mends grout simple structure, easy operation can not block up out the thick liquid mouth.
