Description

Technical Field

[0001] This utility model relates to the field of grouting and sealing technology, and in particular to a grouting and sealing pipe. Background Technology

[0002] Grouting is a technique used in underground engineering to seal cracks, holes, or pipes, and is widely used in tunnels, foundation pits, coal mines, and other engineering fields. The grouting pipe injects grouting material into the target area under high pressure, utilizing the solidification properties of the grouting material to form a strong sealing layer, thereby achieving the purpose of sealing cracks, holes, or pipes. During construction, a grouting hole 100 is drilled in the area to be grouted, and the grouting pipe (or grouting anchor 1) is inserted into the grouting hole 100. A conical grout stop plug 2 is then installed, and grouting can begin. However, during the hammering installation of the conical grout stop plug 2 and / or the high-pressure grouting process, the grouting pipe (or grouting anchor 1) may move towards the rear end of the grouting hole 100 under the impact vibration and high-pressure grouting back thrust; in particular, the grouting anchor 1 cannot be reliably inserted into the grouting hole 100.

[0003] Therefore, there is an urgent need to develop a grouting and sealing pipe that is simple in structure and reliable in installation. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a grouting and sealing pipe. The technical solution adopted by this utility model is as follows:

[0005] A grouting sealing pipe, with its front end inserted into a grouting hole, includes a grouting anchor rod with its front end inserted into the grouting hole, a conical grout stop plug sleeved on the grouting anchor rod and pressing and sealing the grouting hole, a drain pipe inserted into the conical grout stop plug and draining water from the grouting hole, and several anti-reverse installation components sleeved on the front end of the grouting anchor rod.

[0006] The grouting anchor has several concentric holes at its front end; the diameter of the front end of the concentric hole is smaller than the diameter of its rear end; the anti-reverse installation assembly includes a conical seat fitted on the grouting anchor, and a strip column set inside the conical seat and fitted and connected to the concentric holes; the strip column slides along the concentric holes; the diameter of the front end of the conical seat is smaller than the diameter of its rear end.

[0007] Furthermore, a tapered tube is provided at the front end of the grouting anchor rod.

[0008] Furthermore, the grouting anchor has several grout outlet holes.

[0009] Furthermore, a grouting connection flange is provided at the rear end of the grouting anchor rod.

[0010] Furthermore, the conical seat has several notches around its perimeter.

[0011] Furthermore, it also includes: a grout stop plug hammering installation assembly; the grout stop plug hammering installation assembly is located at the rear end of the conical grout stop plug; the grout stop plug hammering installation assembly includes an integrally formed extrusion ring, a conical portion, and an extrusion plate; the extrusion ring contacts the conical grout stop plug; the inner diameter of the extrusion ring is larger than the outer diameter of the grouting anchor rod, and the inner diameter of the extrusion ring is smaller than the outer diameter of the rear end of the conical grout stop plug; the extrusion ring is... Circular ring.

[0012] Furthermore, a hand-grip strip hole is provided on each side of the tapered portion.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) This utility model has several rings of waist-shaped holes at the front end of the grouting anchor rod, and the anti-reverse installation component is fitted into the waist-shaped holes. When the grouting anchor rod and the anti-reverse installation component enter the grouting hole, the anti-reverse installation component is placed at the rear end of the waist-shaped hole, and the outer side of the conical seat is pressed into the grouting hole. When the grouting anchor rod retracts (whether by knocking and vibration or by grouting back-pushing), the anti-reverse installation component slides relative to the front end of the waist-shaped hole and restricts the grouting anchor rod from moving backward, ensuring the reliability of the grouting anchor rod installation.

[0015] (2) The waist-shaped hole of this utility model can not only provide sliding support for the strip column and the conical seat, but also be used for grouting and discharge, achieving the effect of killing two birds with one stone.

[0016] (3) This utility model provides a grout stop plug hammering installation component, which fits against the rear end of the conical grout stop plug, so as to facilitate the hammering installation of the conical grout stop plug. It is convenient and reliable to use.

[0032] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0033] like Figures 1 to 7 As shown, this embodiment provides a grouting sealing pipe, the front end of which is inserted into the grouting hole 100 to facilitate grouting operations. Here, the grouting sealing pipe includes a grouting anchor rod 1 with its front end inserted into the grouting hole 100, a conical grout stop plug 2 sleeved on the grouting anchor rod 1 and pressing and sealing the grouting hole 100, a drain pipe 3 inserted into the conical grout stop plug 2 and draining water from the grouting hole 100, several anti-reverse installation components 5 sleeved on the front end of the grouting anchor rod 1, and a grout stop plug knocking installation component 4 for knocking the conical grout stop plug 2 into place.

[0034] Here, a tapered tube 14 is provided at the front end of the grouting anchor 1, and several grout outlet holes 12 are opened on the grouting anchor 1. A grouting connection flange 11 is provided at the rear end of the grouting anchor 1. In this embodiment, grouting equipment is connected to the external grouting equipment using the grouting connection flange 11. In addition, at least one ring of waist-shaped holes 13 is opened at the front end of the grouting anchor 1. In this embodiment, there are two rings of waist-shaped holes 13, and three holes are provided on each ring. To ensure installation reliability, the diameter of the front end of the waist-shaped hole 13 is smaller than the diameter of the rear end.

[0035] The anti-reverse installation assembly 5 of this embodiment includes a conical seat 51 sleeved on the grouting anchor rod 1, a strip column 52 disposed within the conical seat 51 and connected to the oblong hole 13, and several notches 53 formed on the periphery of the conical seat 51. The strip column 52 slides along the oblong hole 13, and the diameter of the front end of the conical seat 51 is smaller than the diameter of its rear end. In actual construction, the grouting hole 100 is slightly larger than the diameter of the grouting anchor rod 1, and the inner wall of the grouting hole 100 is not smooth. Therefore, the conical seat 51 provides compression support, effectively preventing the grouting anchor rod 1 from slipping out of the grouting hole 100. When the grouting anchor rod 1 and the anti-reverse installation assembly 5 enter the grouting hole 100, the conical seat 51 is positioned at the rear end of the oblong hole 13, providing a certain amount of rotation space and facilitating reliable installation of the grouting anchor rod 1. After the grouting anchor rod 1 has moved to the desired position, the conical anti-reverse plug 2 can be installed by tapping. During grouting, high-pressure grout enters the grouting hole 100, cracks, cavities, etc., exerting a counter-pushing force on the grouting anchor 1. Here, the conical seat 51 is pressed into the grouting hole 100, causing the grouting anchor 1 to retract, resulting in the strip column 52 moving relative to the front end of the waist-shaped hole 13, and reliably limiting the continued backward movement of the grouting anchor 1. Figures 1 to 3 As shown, the two anti-reverse mounting components 5 are respectively placed at the front and rear ends of the oblong hole 13. When entering the grouting hole 100, both anti-reverse mounting components 5 are placed at the rear ends of the oblong hole 13. When the grouting anchor rod 1 retracts, both anti-reverse mounting components 5 are placed at the front ends of the oblong hole 13.

[0036] In this embodiment, to ensure reliable installation of the conical grout stop plug 2, the grout stop plug impact mounting assembly 4 is placed at the rear end of the conical grout stop plug 2, and the conical grout stop plug 2 is reliably pressed against the inlet of the grouting hole 100 by impacting the grout stop plug impact mounting assembly 4. The grout stop plug impact mounting assembly 4 includes an integrally formed compression ring 41, a conical portion 42, and an impact plate 43, as well as hand-grip slots 44 respectively opened on both sides of the conical portion 42. Here, the inner diameter of the compression ring 41 is larger than the outer diameter of the grouting anchor rod 1, and the inner diameter of the compression ring 41 is smaller than the outer diameter of the rear end of the conical grout stop plug 2. Furthermore, the compression ring 41 is... Ring. In this embodiment, the compression ring 41 is attached to the rear end of the conical stop plug 2, which can be installed by tapping.

[0037] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
