[0033] Since the grouting pipe 1 and the PE pipe 2 need to be fixed during construction to ensure the overall pipe penetrating stability and construction quality, but currently the general direct use of tape binding is slow, and after grouting is completed, it is very inconvenient to pull out due to large friction, causing the construction efficiency to decline. By respectively setting the first fixing clamp 3 and the second fixing clamp 4 on the grouting pipe 1 and the PE pipe 2, the first fixing clamp 3 and the second fixing clamp 4 are detachably connected, wherein the first fixing clamp 3 is made of metal material, which ensures the stability and sufficiency of the clamping space 9. After the grouting construction is completed, the first fixing clamp 3 can be disassembled and stored after pulling out the grouting pipe 1, which is convenient for subsequent reuse, and the second fixing clamp 4 is made of plastic and is a disposable structure, which is a consumable product, and the overall manufacturing cost is low, the construction efficiency is high, and it is safe and stable.

[0034] As Figures 7-12 In the preferred scheme, the two sides of the half-ring plate 301 are respectively provided with an ear plate 302, and the opposite two ear plates 302 are connected to form an adjustment gap 10. A first threaded hole 304 is provided through the ear plate 302, and the top wire 6 is provided in the opposite two first threaded holes 304.

[0035] The top wire 6 ensures that the two half-ring plates 301 are installed firmly and reliably, and the top wire 6 is directly installed into the eleventh threaded hole 304 without protruding, which ensures the neatness of the overall structure. At the same time, the length of the ear plate 302 is relatively small compared to the diameter of the first half-ring plate 301, which will not cause inconvenience in installing and dismounting the grouting pipe 1. At the same time, the scheme can also change the size of the adjustment gap 10 according to the installation position of the top wire 6, which adapts to the change of the outer diameter of the grouting pipe 1 within a certain range. Especially when the grouting pipe 1 is repeatedly used and worn, the adjustment gap 10 ensures the stability of the installation. When the two half-ring plates 301 are firmly attached to the outside of the grouting pipe 1 and fixed, the distance of the adjustment gap 10 becomes smaller, and the adjustment gap 10 also plays a role of redundant avoidance to avoid interference.

[0036] In the preferred scheme, the first threaded hole 304 is further provided with a through hole 305, and the circular rod 7 is provided in the opposite two through holes 305.

[0037] By providing the through hole 305, the stability and convenience during installation are ensured.

[0040] In the preferred scheme, the elastic piece 5 is detachably arranged on the half-ring plate 301.

[0043] The depth of the clamping groove 306 is greater than the height of the elastic piece 5, the elastic piece 5 is made of metal material, and the elastic piece 5 is constrained stably through the clamping groove 306, and can also be compressed and deformed to a certain extent, and the grouting pipe 1 is fixed better through the compression and deformation of the elastic piece 5.

[0044] In the preferred scheme, the clamping groove 306 includes a straight portion 307 and a locking portion 308, the elastic piece 5 includes an arc-shaped plate 501, the two side ends of the arc-shaped plate 501 are respectively provided with a lock head 502, the lock head 502 and the locking portion 308 are inserted, and the arc-shaped plate 501 is located in the straight portion 307.

[0045] It is convenient to assemble and disassemble, the use effect is good, the lock head 502 stably cooperates with the locking portion 308, so as to ensure that the arc-shaped plate 501 only moves in the radial direction, and the plurality of elastic pieces 5 cooperate to uniformly distribute the clamping force, thereby ensuring the reliability of clamping.

[0046] As Figures 13-14 In the preferred scheme, the outer side of the half-ring plate 301 is provided with a clamping groove 303, and the second fixing clamp 4 is detachably connected with the clamping groove 303 through a screw 8.

[0047] Since the second fixing clamp 4 is a one-time structure, in order to ensure low manufacturing cost and compensate for the accuracy error during manufacturing, the screw 8 is used to adjust the position of the second fixing clamp 4 relative to the first fixing clamp 3, so as to ensure the accuracy and quality of installation.

[0048] In the preferred scheme, a plurality of second threaded holes 401 are arranged on the second fixing clamp 4, the screw 8 is arranged in the second threaded hole 401, and the screw 8 and the clamping groove 303 are inserted.
