Description

TECHNICAL FIELD

[0001] The utility model relates to grouting pipe technical field more specifically, it relates to a kind of stable adjustment type pipe for grouting. BACKGROUND

[0002] Grouting is a treatment method in engineering, by injecting specific liquid material to target site, to achieve reinforcement, plugging or improving environment, etc., the specific operation of grouting refers to the specific medium is injected into the fissure or interstice of soil, rock or other structures using pressure, these media can solidify and play corresponding engineering role after injection through a series of physical and chemical changes.

[0003] One of the many ways of grouting is reinforcement grouting, the main principle of reinforcement grouting is to adopt the method of lower plugging, upper sealing and intermediate penetration, and drill and inject, among them, sleeve valve pipe grouting is a common means in building foundation reinforcement engineering, the traditional sleeve valve pipe forms airtight space between rubber pad, plus pressure grouting, forms larger pressure, and washes off grouting ring and shell material, so that grouting liquid penetrates into soil pore crack, under the action of grouting pressure, soil in weak structure surface produces splitting phenomenon, grouting liquid will flow along soil crack and fill crack, and the solidified grouting liquid forms splitting grouting vein with soil, which has obvious compaction effect on soil and improves its bearing capacity.

[0004] In the process of reinforcement grouting, grouting core pipe needs to be pulled up one by one, so that the grouting hole on the grouting core pipe can be aligned with the grouting hole of the grouting pipe one by one, so that the grouting material sent by the grouting core pipe can enter the surrounding soil along the grouting hole on the grouting pipe, since the grouting pipe is buried in the hole drilled in advance, and the grouting core pipe is put into the grouting pipe, when pulling up the grouting core pipe step by step, the operator usually needs to have high proficiency, but the symmetry degree of the grouting hole on the grouting core pipe and the grouting hole of the grouting pipe is not uniform, which leads to uneven effect of reinforcement grouting, so a structure is set to solve the problem of inconvenient adjustment of grouting core pipe position in existing part of reinforcement grouting process.

[0005] Therefore, a new scheme is needed to solve this problem. UTILITY MODEL CONTENT

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This stable and adjustable grouting pipe, such as Figure 1 and Figure 2 As shown, the device includes a grouting core tube 1, which is used to stably guide the grout. A limiting part, which can slide along its length, is fitted onto the grouting core tube 1. An adjusting member 2 is rotatably connected to the limiting part for adjusting the locking of the limiting part onto the grouting core tube 1. The locking degree of the limiting part can be adjusted by the adjusting member 2. When the locking degree of the limiting part is relaxed, the limiting part can slide relative to the grouting core tube 1. When the limiting part is gradually tightened, the sliding between the limiting part and the grouting core tube 1 is restricted, thus ensuring the proper functioning of the grouting core tube 1 and the limiting part. The relative position between them remains stable, and the limiting part can abut against the solid part of the top opening of the grouting pipe, thereby achieving stable restriction on the downward sliding process of the grouting core tube 1 along the grouting pipe. This makes it more convenient for the user to adjust the relative position between the grouting core tube 1 and the grouting pipe. The outer wall of the grouting core tube 1 is provided with a scale bar 3 that is consistent with its length direction. The operator can use the scale bar 3 to help judge the relative sliding distance between the grouting core tube 1 and the grouting pipe, making it more convenient to adjust the relative position between the grouting core tube 1 and the grouting pipe.

[0023] like Figure 1 andFigure 2 As shown, a limiting groove 4 is provided at the middle position of the width direction of the scale bar 3. The length direction of the limiting groove 4 is consistent with that of the scale bar 3, and the length of the groove 4 is greater than that of the scale bar 3. A limiting rod 5 is fixedly connected to the limiting part by welding and passes through the limiting groove 4. The user can use the limiting rod 5 to assist in reading the value. At the same time, the limiting rod 5 passing through the limiting groove 4 can limit the relative rotation between the grouting core tube 1 and the limiting part, making the sliding process of the grouting core tube 1 and the process of reading the value with the help of the scale bar 3 more convenient.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the limiting part includes a support tube 6. A limiting ring 7, sleeved on the outside of the grouting core tube 1, is fixedly connected inside the support tube 6 near the top. A limiting groove 8 is formed between the limiting ring 7 on the bottom side and the support tube 6. The limiting groove 8 is used for the grouting pipe to pass through. The groove wall at the top of the limiting groove 8 abuts against the top of the grouting pipe, so that the grouting pipe can achieve positional support and limitation for the limiting part. Several first hexagon socket bolts 9 are threaded onto the support tube 6 and pass through the limiting groove 8 in the horizontal direction. The several first hexagon socket bolts 9 are distributed circumferentially. There are three first hexagon socket bolts 9. After the first hexagon socket bolts 9 pass through the limiting groove 8, they can stably abut against the outer wall of the grouting pipe that passes through it, so as to stably limit the position of the support tube 6 and the limiting part. This ensures that the limiting part can stably limit the grouting core tube 1, making the adjustment process of the grouting core tube 1 more stable, and thus ensuring that the position of the grouting core tube 1 after adjustment and its function are more stable.

[0025] like Figures 2-4 As shown, an adjustment cavity 10 is provided between the two limiting rings 7 and the support tube 6. The adjustment cavity 10 is used to provide a stable clearance during the adjustment process of the limiting part, ensuring that the adjustment function of the limiting part can be stably realized. A hoop 11 is provided inside the adjustment cavity 10 and is sleeved on the outside of the grouting core tube 1. A first through hole 12 is opened on the hoop 11, and two second through holes 13 are opened on the support tube 6, which are concentric with the first through hole 12. The adjusting member 2 passes through the first through hole 12 and the second through hole 13. The adjusting member 2 is set as an internal hexagon screw. This setting ensures that the user can use an electric wrench to achieve stable driving of the adjusting member 2, making the adjustment process of the adjusting member 2 more convenient. When the position of the grouting core tube 1 needs to be adjusted, the hoop 11 is first loosened to restrict the grouting core tube 1. After the grouting core tube 1 is moved to the required position, the hoop 11 is locked, thereby realizing the stable adjustment and limiting of the position of the grouting core tube 1.

[0026] like Figures 2-4As shown, the adjusting component 2 is threaded with symmetrically arranged adjusting nuts 14. A limiting ring 7 near one adjusting nut 14 is fixedly connected by welding with symmetrically arranged limiting plates 15 used to restrict the rotation of the adjusting nut 14. Both limiting plates 15 abut against the adjusting nut 14 on one side, allowing the limiting plates 15 to stably limit the rotation of the adjusting nut 14, enabling the adjusting component 2 to rotate relative to the adjusting nut 14. This allows the position between the two adjusting nuts 14 to be adjusted. When the two adjusting nuts 14 approach each other, they will cause the clamping ring 11 to tighten, achieving stable limiting of the relative sliding process between the limiting part and the grouting core tube 1. This ensures that the grouting core tube 1 remains in a stable position after adjustment, making the position and function of the grouting core tube 1 more stable. When the two adjusting nuts 14 move away from each other, they will cause the clamping ring 11 to loosen, allowing the grouting core tube 1 to slide relative to the limiting part.
