Description

Technical Field

[0001] This utility model relates to the field of waterproof construction of reinforced concrete tunnel lining, and in particular to the technical field of waterproof material installation for single reinforced concrete tunnel lining segments. Background Technology

[0002] In shield tunneling, waterproofing of reinforced concrete segment joints is a key control item. The installation quality of waterproofing materials will likely affect the quality of the formed tunnel, especially during the waterproofing construction process, where issues such as bulging, contamination, and uneven installation of waterproofing materials are prone to occur.

[0003] Traditional waterproofing material installation methods involve tapping with a rubber mallet and manually pressing, supplemented by enhanced technical training and briefings for workers to control the quality of waterproofing construction. However, these methods have significant drawbacks: traditional installation takes a long time; the installed waterproofing material is not secure; the surface of the installed waterproofing material is severely contaminated; and the installed waterproofing material is not on the same horizontal plane, failing to meet the construction design requirements.

A guide roller is installed at the front end of the lower fixing frame.

[0007] The handle and mounting bracket are made of high-strength aluminum alloy.

[0008] The two fixing brackets are arranged symmetrically along the center line of the longitudinal section of the handle.

[0009] The two fixing brackets are symmetrically provided with threaded through holes in the cross-sectional direction of the structure for the adjustment rod to pass through.

[0010] The adjusting rod is a threaded screw, made of cast iron with threads throughout. Rotating handles are provided at both ends of the adjusting rod. The rotating handles are cast iron parts, and the diameter of the rotating handles is smaller than the diameter of the pressing roller.

[0011] Both the pressing roller and the guide roller are made of rubber.

[0012] The longitudinal section of the pressing roller has a through hole for inserting the adjusting rod and installing a rotating bearing. The rotating bearing and the adjusting rod are secured and locked by wedge blocks.

[0013] The clamping roller is equipped with enlarged stop rollers at both ends.

[0014] A rotating bearing is installed in the middle of the guide roller.

[0015] An extended section is provided at the rear end of the guide roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model can quickly realize the installation of waterproof materials, improve the pass rate of one-time waterproof material installation, and save labor.

[0018] 2. This utility model has high strength, is simple to operate, and has low cost.

[0029] The present invention will be further described below with reference to specific embodiments. These specific embodiments are further explanations of the principle of the present invention and are not intended to limit the present invention in any way. Any technology that is the same as or similar to the present invention does not exceed the protection scope of the present invention.

[0030] See Figures 1-6 This utility model provides a tool for installing waterproofing material on reinforced concrete tunnel segments of shield tunnels. The tool includes a handle 1, a fixing frame 5, an adjusting rod 2, a pressing roller 4, and a guide roller 3.

[0031] A fixing bracket 5 is installed at each end of the cross section of the handle 1 for installing and fixing the adjusting rod 2. The two fixing brackets 5 are symmetrically arranged along the center line of the longitudinal section of the handle 1. The two fixing brackets 5 are symmetrically provided with threaded through holes in the cross section of the structure for the adjusting rod 2 to pass through. When installing the adjusting rod 2, it is simply rotated through the threaded through hole of the fixing bracket 5 to complete the installation. The handle 1 and the fixing brackets 5 are made of high-strength aluminum alloy, which is lightweight yet has sufficient strength to withstand long-term continuous operation without damage or deformation.

[0032] The adjusting rod 2 passes through the middle of the pressing roller 4 and is mounted on two fixed brackets 5 at both ends. The adjusting rod 2 is mounted on the fixed brackets 5 to adjust the working part of the pressing roller 4. The adjusting rod 2 is a threaded screw made of cast iron with threads throughout. Rotary handles at both ends of the adjusting rod 2 are adjustable to follow the path of the pressing roller 4. The diameter of the rotary handles is smaller than the diameter of the pressing roller 4. The adjusting rod 2 can adjust the position of the pressing roller 4 according to the different cross-sectional positions of the waterproof material 7 by rotating the handles at both ends of the cross-section.

[0033] The longitudinal section of the clamping roller 4 has a through hole along the center line for the adjustment rod 2 to be inserted and a rotating bearing to be installed. The rotating bearing and the adjustment rod 2 are secured and locked by wedges. Enlarged retaining wheels are provided at both ends of the clamping roller 4 to prevent the waterproof material 7 from falling off the clamping roller 4.

[0034] A guide roller 3 is mounted on the front end of the lower fixing frame 5 to prevent the action trajectory of the pressure roller 4 from deviating. A rotating bearing is installed in the middle of the guide roller 3, and an extension section is provided at the rear end of the guide roller 3. Both the pressure roller 4 and the guide roller 3 are made of rubber to ensure lightweight operation while guaranteeing sufficient friction between the roller and the waterproof material 7.

[0035] This tool is used for waterproofing construction of reinforced concrete tunnel segments 1 in tunnel boring machines. During use, a section of waterproofing material 7 is pre-installed into the sealing groove of the reinforced concrete tunnel segment 1. The tool is then placed at the location where the waterproofing material 7 is installed on the tunnel segment 1. The clamping roller 4 is positioned above the waterproofing material 7, serving as the main load-bearing component. Next, the guide roller 3 is placed on the outer arc surface of the concrete tunnel segment 1 (i.e., the back of the segment 1), primarily constraining the tool's movement direction. Then, the rotating handles at both ends of the adjusting rod 2 are rotated to adjust the relative position of the clamping roller 4 on the waterproofing material 7, ensuring precise alignment. Finally, the operator grips the handle 1, pushes it, and rolls it forcefully. The pressure from the clamping roller 4 is transmitted to the waterproofing material 7, firmly adhering it to the tunnel segment 1. The tool rolls along the installation direction of the waterproofing material 7, completing the efficient and rapid installation of the waterproofing material 7.
