At present, the water stop work of the pipe joint is mainly realized by adopting a GINA rubber water stop and an OMEGA rubber water stop, and the function and the quality of the GINA rubber water stop are almost determined by taking the GINA rubber water stop as a first layer waterproof device of the immersed tube tunnel. Whether the compression amount of the GINA rubber water stop after installation meets the design requirement or not determines whether the GINA rubber water stop can become an important guarantee after installation of pipe joints or not. Therefore, it is particularly important to obtain the compression amount of the GINA rubber water stop after installation.
In view of this, chinese patent 201210421333.2 discloses a method for measuring bending stiffness of immersed tube tunnel joints, which involves a method for calculating compression amount of water stops.

However, the compression amount of the GINA water stop obtained by the calculation of the structural simplification model is greatly deviated from the actual compression amount. Therefore, a compression amount measuring device for the GINA water stop is needed, and the compression amount measuring device can be applied to a narrow measurement space and can be used for directly measuring the compression amount of the GINA water stop in a joint cavity of two pipe joints, so that the obtained compression amount data is more real and accurate.

Referring to fig. 1 to 7, an exemplary embodiment of the GINA water stop compression measuring apparatus according to the present utility model is provided, which is used for directly measuring the compression of the GINA water stop between two pipe sections after the two pipe sections are abutted and the drainage work of the joint chamber is completed, so as to obtain real and accurate GINA water stop compression data. The GINA water stop compression amount measuring device comprises a fixing piece 3, a first measuring ruler 1, a second measuring ruler 2 and a locking piece 31.
The fixing piece 3 is a cuboid with a hollow inserting cavity, and the fixing piece 3 is provided with a mounting hole which is matched with the locking piece 31. In order to facilitate the measurement work, the first measuring ruler 1 and the second measuring ruler 2 adopt L-shaped rulers with the same width. The size of the fixing piece 3 is matched with the first measuring ruler 1 and the second measuring ruler 2, so that the first measuring ruler 1 and the second measuring ruler 2 can be slidably inserted into the hollow insertion cavity of the fixing piece 3 and cannot influence measurement reading. Specifically, the width of the hollow inserting cavity of the fixing piece 3 is larger than the width of the first measuring ruler 1, and the thickness of the hollow inserting cavity of the fixing piece 3 is larger than the sum of the thicknesses of the first measuring ruler 1 and the second measuring ruler 2, so that the first measuring ruler 1 and the second measuring ruler 2 can be simultaneously and slidably inserted into the hollow inserting cavity of the fixing piece 3.
The first measuring ruler 1 and the second measuring ruler 2 are relatively inserted into the hollow inserting cavity of the fixing piece 3 from two ends of the fixing piece 3, the first measuring ruler 1 and the second measuring ruler 2 relatively slide along the hollow inserting cavity, so that the first measuring ruler 1 penetrates out of the inserting end of the second measuring ruler 2, the second measuring ruler 2 penetrates out of the inserting end of the first measuring ruler 1, the first measuring ruler 1 and the second measuring ruler 2 continuously relatively slide to the two ends of the first measuring ruler 1 and the second measuring ruler 2 to be flush, and at the moment, the length of the GINA water stop compression measuring device is reduced to the minimum, and the GINA water stop can be placed in a gap.
The first measuring ruler 1 and the second measuring ruler 2 which are inserted into the hollow insertion cavity in a sliding manner are in sliding abutting connection. The retaining member 31 is detachably connected with the fixing member 3 through the mounting hole, and the retaining member 31 passes through the mounting hole and is in butt joint with the first dipperstick 1, so that the retaining member 31 can lock the first dipperstick 1 and the second dipperstick 2 which are in sliding butt with each other, and the first dipperstick 1 and the second dipperstick 2 are prevented from sliding during reading.
In order to ensure the accuracy of the measurement results, to ensure the levelness of the first measuring ruler 1 and the second measuring ruler 2 when the measurement work is performed, a tube level 32 is arranged on the fixing piece 3, and whether the first measuring ruler 1 and the second measuring ruler 2 always maintain the horizontal state in the process of performing the measurement work is judged according to whether bubbles in the tube level 32 are centered. Before the measurement device and reading are fixed, the centering of the bubble in the tube level 32 should be determined to ensure accuracy of the reading.
The GINA water stop compression measuring device with the length reduced to the minimum is placed in a gap where the GINA water stop is positioned and the level is adjusted, and then the first measuring ruler 1 and the second measuring ruler 2 continue to slide relatively along the hollow inserting cavity of the fixing piece 3 until the end parts of the first measuring ruler 1 and the second measuring ruler 2 penetrating out of the fixing piece are respectively in tight contact with the two ends of the gap. Confirm that the bubble in the tube level 32 is still centered and then tighten the locking member 31 to lock the first measuring scale 1 and the second measuring scale 2. At this point, a reading operation can be performed.
The compression amount of the GINA water stop is from the end part of the first measuring ruler 1 penetrating out of the fixing piece 3 to the end part of the second measuring ruler 2 penetrating out of the fixing piece 3, and the specific reading mode is as follows: the length of the first measuring scale 1 is read by taking the first measuring scale 1 as a reference scale (the length is from the end of the first measuring scale 1 penetrating out of the fixing piece 3 to the side of the first measuring scale 1 not penetrating out of the fixing piece 3), and the length is fixed and does not need to be read repeatedly as long as the reference scale is not replaced. The length of the second measuring scale 2 (which is the length from the end of the second measuring scale 2 penetrating the fixing member 3 to the side of the first measuring scale 1 not penetrating the fixing member 3) is then read, and the two lengths read are added to obtain the compression amount of the GINA water stop.
After the reading work is finished, the locking piece 31 is unscrewed, the first measuring ruler 1 and the second measuring ruler 2 slide back to back along the hollow inserting cavity of the fixing piece 3 until the two ends of the first measuring ruler 1 and the second measuring ruler 2 are flush, the length is reduced to the minimum, then the measuring ruler is taken out from the gap, and the compression amount of the GINA water stop belt of the next measuring point is continuously measured. In order to improve the efficiency of the measuring work, the installation and the disassembly of the device are more convenient, a handle 311 is arranged on the locking piece 31, and the locking piece 31 is screwed or unscrewed by rotating the handle 311. The locking member 31 is a locking bolt, and the handle 311 is a bolt handle.
