Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure grouting pipes, in particular to a high-pressure grouting pipe with adjustable length. Background Art

[0002] High-pressure grouting pipes are commonly used for grouting reinforcement and anti-seepage treatment in underground projects. However, due to the high internal and external pressures exerted on the pipes during the high-pressure grouting process, they are prone to deformation and damage. Therefore, rigid pipe structures are currently widely used to enhance their pressure resistance. However, while rigid pipes can prevent deformation, their rigidity prevents them from being adjusted for expansion and contraction, making them less adaptable during construction. When the construction depth changes, rigid pipes cannot be flexibly adjusted in length, requiring additional splicing or cutting to adapt to different construction requirements, increasing construction complexity and labor costs.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0027] Example

[0028] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, the present invention is a high-pressure grouting pipe with adjustable length, which includes a main pipe 1 and a corrugated pipe 2. The design of the corrugated pipe 2 utilizes its folding, elongating, and shortening functions to facilitate adjustment of the relative length between the main pipe 1 and the end pipe 3. The outlet end of the corrugated pipe 2 is connected to the end pipe 3, and the outside is wrapped with a wire mesh 21 to enhance its strength and pressure resistance. It should be noted that the maximum diameter folding position of the corrugated pipe 2 is the folding protrusion 22, and the minimum diameter folding position of the corrugated pipe 2 is the folding recess 23. A pair of fixing plates 4 are provided, each fixedly mounted on the adjacent ends of the main pipe 1 and the end pipe 3.

[0029] Reference Figure 1As shown, one end of the guide rod 5 is fixed to the fixing plate 4 of the end pipe 3, and the other end is inserted through the fixing plate 4 of the main pipe 1, serving as a guide. When adjusting the length, the operator can pull the end pipe 3 to extend or retract the corrugated pipe 2. Positioning rings 6 are sleeved onto the corrugated pipe 2, and multiple positioning rings 6 are provided, corresponding one-to-one with the folded protrusions 22 of the corrugated pipe 2. The positioning rings 6 are slidably mounted on the guide rod 5 to ensure their stable position during adjustment, preventing the corrugated pipe 2 from expanding and deforming excessively under high pressure, thereby causing damage.

[0030] Reference Figure 1 and Figure 2 As shown, each positioning ring 6 is provided with a V-shaped spring clip 7. Multiple V-shaped spring clips 7 are provided along the circumference of the positioning ring 6, with one end of each V-shaped spring clip 7 fixed to the positioning ring 6 and the other end fixed to the wire mesh 21. The design of the V-shaped spring clip 7 enables the positioning ring 6 to move with each segment of the corrugated pipe 2 and promptly follow the deformation of the corrugated pipe 2 when it deforms, further enhancing the flexibility of adjustment.

[0031] Reference Figure 2 and Figure 4 As shown, ear plates 61 are integrally welded on both sides of the positioning ring 6, and the ear plates 61 are slidably mounted on the guide rod 5 to provide additional stable support. A damping ring 42 is provided on the fixing plate 4. After the bellows is extended to a certain length, the setting of the damping ring 42 can play a role in damping and positioning. An elastic limiting plate 8 is provided between two adjacent positioning rings 6. The elastic limiting plate 8 is V-shaped and inserted into the folded recess 23 of the corrugated pipe 2 to ensure that the shape of the corrugated pipe 2 remains stable and plays a supporting role. A rubber plate 81 is provided on the side of the elastic limiting plate 8 close to the corrugated pipe 2 to further enhance the buffering effect.

[0032] Reference Figure 4 As shown, a pair of handles 9 are coaxially rotatably mounted on the end pipe 3. These handles are designed to be symmetrically positioned about the end pipe 3's axis for easy operation. Specifically, when installing the handles 9, a rotating ring 31 can be coaxially welded to the end pipe 3, with the ring bodies 91 of the pair of handles 9 rotating on the rotating ring 31. Finally, the outer surface of the wire mesh 21 is covered with a rubber anti-wear layer 211, enhancing overall wear resistance and extending the pipe's service life.

[0033] Through the above design, the present invention can realize convenient length adjustment of the high-pressure grouting pipe while ensuring that the telescopic part of the grouting pipe is not easily deformed or damaged, thereby improving the safety and efficiency of construction.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
