[0037] At present, some projects such as subway tunnels and high-speed railway tunnels are constructed by shield method. Reinforced concrete lining segments are important components of shield tunneling technology. After the steel cage is tied, all segments need to be buried with grouting pipes first, and then concrete is poured to ensure smooth secondary grouting interfaces in the tunnel.

[0038] After the steel cage is tied, it has a certain vertical height. The base of the grouting pipe is located below the steel cage. When the grouting pipe and the base are threaded together, they are usually tightened manually. This operation method is easy to cause hand slippage when rotating and tightening, making the connection between the grouting pipe and the base loose. Under the impact and vibration of concrete, the grouting pipe will be offset, resulting in serious indentation of the grouting pipe or leakage and plugging of holes. The safety and durability of the pipe segment are seriously affected.

[0039] The utility model provides a segment grouting pipe fastening tool 100 for solving the above problems.

[0040] See also Figure 1 to Figure 2 In one embodiment of the utility model, the segment grouting pipe fastening tool 100 mainly includes a first sleeve 1 and a force-applying structure provided on the first sleeve 1. Specifically, during the construction process, the steel cage is firstly tied on the base. After the steel cage is tied, multiple grouting pipes need to be installed on the base, and concrete is poured on the steel mesh on the base for vibration. In order to ensure the stability of the connection between the grouting pipe and the base, an external thread structure is often provided on one end of the grouting pipe connected to the base. During the actual installation process, the construction personnel often hold the upward end of the grouting pipe, insert the grouting pipe into the steel cage, and then screw the grouting pipe on the base for fixing. In this fixing method, since the steel cage has a certain vertical height, sometimes the construction personnel need to put their hands into the steel cage to twist one end of the grouting pipe. This method is often difficult to apply force. At the same time, the circular grouting pipe is also easy to slip during the manual twisting process, so it often causes the grouting pipe to be screwed not firmly enough. In the subsequent grouting and vibration process on the base, the grouting pipe is also very easy to deviate under the pressure of concrete, thereby affecting the subsequent grouting operation of the grouting pipe. In view of the above actual situation, the first sleeve 1 is set in this embodiment. In the actual use process, the grouting pipe is first pre-connected with the base by artificial thread at its lower end, and then the first sleeve 1 is sleeved on the outer periphery of the grouting pipe from the upper end of the grouting pipe, and the lower end of the grouting pipe is fixed by the connecting structure, and then the first sleeve 1 and the grouting pipe are driven to rotate around their axis by the force applying part 3. In this process, since the outer sleeve has a higher vertical height relative to the grouting pipe, the driving end can be located outside the steel cage, and at the same time, the part of the force applying part 3 is higher than the outer peripheral wall of the first sleeve 1, which enables the relevant operators to screw the grouting pipe outside the steel cage, and the force applying part 3 forms a certain force arm effect, so that the screwing process is better force applied, so that the grouting pipe can be better screwed on the base for fixing, ensuring the connection performance between the grouting pipe and the base, and making the connection operation of the two more convenient.

[0041] The connection structure is designed according to the actual shape of the connection end of the grouting pipe. Specifically, on the peripheral wall of the connection end between the grouting pipe and the base, ribs protruding outward are provided on the peripheral wall of the grouting pipe, and usually such ribs are square structures. Therefore, in this embodiment, the connection structure is set as a slot portion 11, and the slot portion 11 is set corresponding to the rib. When in use, the slot portion 11 is clamped on both sides of the rib along the circumferential direction of the grouting pipe. When the slot portion 11 rotates with the first sleeve 1, it can well drive the entire grouting pipe to rotate together. The connection structure is set as follows Figure 2 and Figure 4 The described slot, on one hand, can achieve a good fixing effect and can provide sufficient circumferential driving force when the first sleeve 1 rotates; on the other hand, this structure is simple, reliable, easy to implement, and can well meet actual needs.

[0042] In addition, in the present solution, the slot portion 11 and the first sleeve 1 are configured as an integrated structure. In fact, in actual use, the two can be configured as an assembled structure to facilitate the replacement and maintenance of the slot portion 11 at a later time.

[0043] In the actual construction process, the specifications of the steel cages to be erected vary according to the actual situation. Under the condition of sufficient supporting force, the height and width of the steel cages also need to be adaptively adjusted to achieve the effect of cost saving. In order to adapt to steel cage structures of different heights within a certain range and enable construction workers to perform screwing operations on the outside of the steel cages, in this embodiment, Figure 2 , Figure 3 and Figure 4 As shown, an adjustment member is provided. Specifically, the force transmission sleeve 2 in the adjustment member is sleeved on the outer periphery of the first sleeve 1, and the outer periphery of the first sleeve 1 can slide in the force transmission sleeve 2 along its axial direction. During use, the length of the fixed end extending out of the force transmission sleeve 2 can be limited by the positioning structure according to the actual height of the steel cage structure, thereby adjusting the overall length of the force transmission sleeve 2 and the first sleeve 1, so that the entire device can be suitable for various construction scenes. In addition, by adopting the solution in this embodiment, when the entire device is not in use, the first sleeve 1 can be stored in the force transmission sleeve 2, thereby reducing the overall length of the entire device, and achieving a portable effect to a certain extent.

[0044] Specifically, when the overall length of the force transmission sleeve 2 and the first sleeve 1 is adjusted, the positioning protrusion 12 slides on the main groove portion 211 along the axial direction of the force transmission sleeve 2. When adjusted to a suitable position, the positioning protrusion 12 is slid to the corresponding limiting groove portion 212, and the limiting groove portion 212 limits the positioning protrusion 12 in the following manner: Figure 2 The vertical movement shown in the figure adjusts the overall length formed by the force transmission sleeve 2 and the first sleeve 1 to the current state.

[0045] It is conceivable that one guide groove 21 can be provided, or multiple guide grooves 21 can be provided along the peripheral wall of the force transmission sleeve 2. At the same time, multiple positioning protrusions 12 can be provided corresponding to multiple guide grooves 21. Multiple positioning protrusions 12 can further increase the shear force of the first sleeve 1 around the axial direction, thereby making the entire device have better torsional strength.

[0046] Among them, Figure 2 and Figure 4 As shown, in this embodiment, the limiting groove is set as a right-angle groove, and the horizontal groove portion 212b of the right-angle groove is connected to the main groove portion 211, and the vertical groove portion 212a of the right-angle groove is as shown in FIG. Figure 3 The limiting groove is set upward as shown. When the grouting pipe is actually screwed, the user first slides the positioning protrusion 12 into the vertical groove portion 212a. When screwing, a certain downward force needs to be applied. At this time, the positioning protrusion 12 is limited at the upward end of the vertical groove portion 212a. When the construction personnel apply downward force and screw the force transmission sleeve 2 at the same time, the positioning protrusion 12 can maintain a stable position in the vertical groove portion 212a, so that the overall length formed by the force transmission sleeve 2 and the first sleeve 1 remains stable.

[0047] In order to ensure that the first sleeve 1 can maintain a stable position in the force transmission sleeve 2 and will not fall out by itself when the entire device is in the storage state, in this embodiment, a limiting hole 22 is provided on the force transmission sleeve 2 corresponding to the uppermost vertical groove portion 212a, and a rubber block 23 is provided on the force transmission sleeve 2 corresponding to the limiting hole 22. When stored, the positioning protrusion 12 is limited to the uppermost vertical groove portion 212a by the rubber block 23, thereby preventing the first sleeve 1 from sliding out of the force transmission sleeve 2 under non-artificial conditions.

[0048] Specifically, the force-applying portion 3 is configured as a rotatable and foldable handle 32, wherein the handle 32 is rotatably mounted on a mounting seat 31 at one end of the force transmission sleeve 2. When in use, the handle 32 is rotated to be perpendicular to the force transmission sleeve 2, and then the first sleeve 1 and the force transmission sleeve 2 can be driven to rotate together by the handle 32.

[0049] In order to facilitate the folding of the handle 32, the handle 32 can be made of metal material or part of it can be made of metal material. Then, a corresponding magnet block 41 is set on the storage seat 4 corresponding to the metal area of ​​the handle 32. When the handle 32 is rotated to a vertical state, it can be magnetically attracted to the storage seat 4, thereby further improving the portability of the entire device.

[0050] It should be noted that in order to enable the slot portion 11 to achieve a good clamping and fixing effect, the size of the slot portion 11 in this solution is designed according to the size of the ribs at the end of the existing grouting pipe. Specifically, the vertical height of the slot portion 11 along the first sleeve 1 is L, 100mm≤L≤160mm, and the slot width of the slot portion 11 is W, 30mm≤L≤50mm. The above dimensions enable the slot portion 11 to accommodate the ribs well, and in actual application, the inner diameter of the first sleeve 1 is as close as possible to the outer diameter of the grouting pipe, so that the slot portion 11 can achieve a good force effect.

[0051] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
