Embodiment 1

[0054] Such as Figure 1 ~ Figure 4 As shown, a dynamic sealing grouting hood includes a straight pipe 1, a cover plate 2 is arranged at one end of the straight pipe 1, a sealing member 3 is arranged between the straight pipe 1 and the cover plate 2, and the cover The length of the plate 2 in the radial direction of the straight pipe 1 is greater than or equal to the outer diameter of the straight pipe 1, and the end surface of the cover plate 2 away from the straight pipe 1 is provided with a fastener 4, the The fastener 4 is connected with the beam body pre-embedded anchor backing plate 6 using bolts 5, and the beam body pre-embedded anchor backing plate 6 cooperates with the end of the straight pipe 1 away from the cover plate through the sealing part 3, Set dry hard mortar 7 in the airtight space formed by the straight pipe 1, the cover plate 2, the seal 3 and the beam body pre-embedded anchor plate 6, and the material of the straight pipe 1 is polychlorinated The sealing...

Embodiment 2

[0057] Such as Figure 2 ~ Figure 4 As shown, in the structure as described in Embodiment 1, the sealing ring 31 is a rectangular sealing ring 311, the fastener 4 is detachably connected to the cover plate 2, and the fastener 4 is Linear type, for example, the fastener 4 can be a steel plate.

[0058] In the above scheme of the present embodiment, the sealing ring 31 is a rectangular sealing ring 311, and the type of the sealing ring 31 is a common sealing ring, which can be directly purchased or easily processed. In addition, the fastener 4 and the cover plate 2 are detachably connected, which can Make the fastener 4 and the cover plate 2 relatively independent, so that the damage of one of the fastener 4 and the cover plate 2 will not affect the use of the other part, that is to say, both the fastener 4 and the cover plate 2 When one of the parts is damaged, the other part can be used normally, and there is no need to replace the two parts at the same time. In addition, the...

Embodiment 3

[0060] Such as Figure 2 ~ Figure 4 As shown, in the structure as described in Embodiment 2, the thickness of the rectangular sealing ring 311 in the radial direction is greater than the thickness of the straight cylinder 1 in the radial direction, and the fastener 4 and the cover plate 2 welding.

[0061] In the above solution of this embodiment, the thickness of the rectangular sealing ring 311 along the radial direction is greater than the thickness of the straight cylinder 1 along the radial direction. It can completely cover the end faces of the two ends of the straight cylinder 1, so when the rectangular sealing ring 311 is squeezed and deformed by tightening the bolt 5, the gap between the end surfaces of the two ends of the straight cylinder 1 and the embedded anchor plate 6 of the beam body or the cover plate 2 is completely covered. Filling, like this, can have better sealing performance.

[0062] The fastener 4 is welded to the cover plate 2. In this way, the comb...

Abstract

The invention relates to the technical field of pipeline grouting, in particular to a dynamic sealing grouting cover and a using method thereof. The dynamic sealing grouting cover comprises a straight pipe. A cover plate is arranged at one end of the straight pipe. A sealing part is arranged between the straight pipe and the cover plate. The length of the cover plate in the transverse direction of the straight pipe is not smaller than the outer diameter of the straight pipe. A fastener is arranged on the face, away from the straight pipe, of the cover plate. The fastener and a beam body embedded anchor bearing plate are connected through bolts. The beam body embedded anchor bearing plate is matched with the end, away from the cover plate, of the straight pipe through the sealing part. Dry hard mortar is arranged in a closed space formed by the straight pipe, the cover plate, the sealing part and the beam body embedded anchor bearing plate. Small gaps between the straight pipe and the beam body embedded anchor bearing plate can be blocked through the sealing part when the bolts are screwed, and under the action of the grouting pressure and grout, the small gaps can be filled and blocked with tiny particles in the dry hard mortar, so that the sealing performance of the grouting cover can be reinforced dually.

Description

technical field [0001] The invention relates to the technical field of pipeline grouting, in particular to a dynamic sealing grouting cover and a using method thereof. Background technique [0002] At present, most of the grouting covers used are cut and welded steel plates. The processing cost is high, heavy, difficult to install and disassemble, and the sealing effect is not reliable. It stipulates the time requirements for wire cutting within 24 hours and grouting within 48 hours after final tensioning. Most construction units adopt a combination of two measures: mortar sealing, anchoring and pressurizing the grout cover to ensure the sealing effect, and the grout cover must wait for the grout after grouting The dismantling and turnover can only be done after the initial setting, and the cleaning and maintenance of the dismantled grouting hood after the initial setting of the grout is troublesome, resulting in less turnover times and high amortization cost of the grouting...
