[0030] 3. By setting up a cleaning mechanism, it is convenient to clean the surface of the tunnel segment joint to ensure that there is no dust on the surface. The rotation of the sprocket drives the chain to rotate, thereby driving the nozzle to move along the surface of the tunnel segment joint.

[0047] Reference Figure 2-Figure 10 A method for using a joint water stop for a prefabricated pipe gallery comprises the following steps:

[0048] S1. First, clean the joint surface of the tunnel segment 1 using a fixing device to ensure that the surface is free of dust.

[0049] S2. Place the strip waterstop 2 at the joint of the pipe gallery segment 1 at a predetermined position, and fix it tightly to the pipe gallery segment 1 through the metal insert 22.

[0050] S3. Fill the expansion sealing material 23 into the gap between the strip water stop 2 and the joint of the pipe gallery segment 1 to complete the installation.

[0051] In order to facilitate the installation of the strip waterstop 2 and the corridor segment 1 together, the fixing device includes a support frame 3 and a cleaning mechanism, a clamping mechanism and a fixing mechanism arranged on the support frame 3. The cleaning mechanism includes a nozzle 4. A blow box 41 is arranged on the side of the support frame 3 away from the corridor segment 1. A folded pipe 42 is arranged between the blow box 41 and the nozzle 4, so that the gas sprayed by the nozzle 4 can clear the dust on the surface of the corridor segment 1.

The surfaces of the four circular plates 6 are provided with arc-shaped blocks 61. The surfaces of the arc-shaped blocks 61 are respectively slidably fitted with the surfaces of the strip waterstop 2 and the corridor segment 1, so that the strip waterstop 2 is in close contact with the surface of the corridor segment 1.

[0052] In order to drive the nozzle 4 to move along the joint surface of the pipe gallery segment 1, the cleaning mechanism also includes a limit frame 43 fixedly installed on the side of the support frame 3 close to the pipe gallery segment 1, and a slider 44 is slidably sleeved on the surface of the limit frame 43. The nozzle 4 is arranged on the side surface of the slider 44 close to the pipe gallery segment 1. A chain 45 is arranged on the inner surface of the limit frame 43. The surface of the support frame 3 is provided with connecting sleeves 46 distributed in a rectangular array through bearings. The surfaces of the four connecting sleeves 46 are fixedly sleeved with sprockets 47. The teeth of the four sprockets 47 are meshed with the pins of the chain 45. The other side surface of the slider 44 is fixedly connected to the pin of the chain 45. The rotation of the sprocket 47 drives the slider 44 to slide along the surface of the limit frame 43, thereby driving the nozzle 4 to move. There are four sprockets 47, which are distributed in a rectangular array to ensure that the chain 45 remains stable during movement.

[0053] In order to drive the chain 45 to rotate, a driving motor 48 is fixedly installed on the surface of the side of the support frame 3 away from the corridor segment 1, and a driving gear 49 is installed on the surface of the side of the support frame 3 close to the corridor segment 1 through a bearing. A driven gear 410 is fixedly sleeved on the surface of one of the connecting sleeves 46, and the driving gear 49 is meshed with the driven gear 410. One end of the output shaft of the driving motor 48 is fixedly sleeved with the axis of the driving gear 49. The rotation of the output shaft of the driving motor 48 drives the driving gear 49 connected thereto to rotate, and the rotation of the driving gear 49 drives the driven gear 410 meshed therewith to rotate. The rotation of the driven gear 410 drives the connecting sleeve 46 connected thereto to rotate, and the rotation of the connecting sleeve 46 drives the sprocket 47 connected thereto to rotate. The rotation of the sprocket 47 drives the chain 45 to rotate, thereby rotating the other sprockets 47.

[0054] In order to facilitate driving the nozzle 4 close to the joint of the pipe gallery segment 1, a heat dissipation shell 411 is provided on the side of the slider 44 close to the nozzle 4, a rotating motor 412 is fixedly installed inside the heat dissipation shell 411, one end of the output shaft of the rotating motor 412 extends to the outside of the heat dissipation shell 411 and is fixedly sleeved with a bent square tube 413, the nozzle 4 is installed on the end surface of the square tube 413 away from the heat dissipation shell 411, a connecting plate 414 is provided between the heat dissipation shell 411 and the square tube 413, and a push rod is fixedly installed on the upper surface of the slider 44. The air cylinder 415 is driven, and one end of the piston rod of the air cylinder 415 is fixedly connected to the surface of one side of the connecting plate 414. The connecting plate 414 connected thereto is driven to move by the extension and retraction of the piston rod of the air cylinder 415. The movement of the connecting plate 414 drives the heat dissipation shell 411 and the square tube 413 to move. The movement of the square tube 413 drives the nozzle 4 to move. The rotation of the output shaft of the rotating motor 412 drives the square tube 413 connected thereto to rotate, thereby driving the nozzle 4 to rotate, so that the nozzle 4 is always facing the joint of the corridor segment 1, which is convenient for cleaning.

[0055] By setting up a cleaning mechanism, it is convenient to clean the surface of the joint of the pipeline gallery segment 1 to ensure that there is no dust on the surface. The rotation of the sprocket 47 drives the chain 45 to rotate, thereby driving the nozzle 4 to move along the surface of the joint of the pipeline gallery segment 1. At the same time, the cooperation between the rotating motor 412 and the chain 45 allows the nozzle 4 to always be aligned with the joint of the pipeline gallery segment 1, so that the gas ejected by the nozzle 4 cleans the dust on the joint of the pipeline gallery segment 1 to achieve a cleaning effect.

[0056] In order to drive the starting clamp to approach the pipe gallery segment 1, the clamping mechanism also includes a groove 51 opened on the surface of one side of the support frame 3 close to the pipe gallery segment 1, the inner walls of the three grooves 51 are all installed with screws 52 through bearings, and three reduction motors 53 are fixedly installed on the surface of the support frame 3. One end of the output shaft of the reduction motor 53 is fixedly sleeved with one end of the screw 52, ​​and the surfaces of the three screws 52 are all threadedly sleeved with T-blocks 54. The surface of the T-block 54 is slidably engaged with the inner wall of the groove 51, and the one side surface of the three T-blocks 54 is fixedly installed with a first driving cylinder 55. The three pneumatic clamps 5 are respectively installed on one end of the piston rod of the three first driving cylinders 55, and the rotation of the output shaft of the reduction motor 53 drives the screw 52 connected thereto to rotate. The rotation of the screw 52 drives the T-block 54 connected thereto to move along the inner wall of the groove 51, and the movement of the T-block 54 drives the first driving cylinder 55 and the pneumatic clamp 5 connected thereto to move, and the extension and retraction of the piston rod of the first driving cylinder 55 drives the pneumatic clamp 5 connected thereto to extend and retract.

[0057] In order to fix the position of the strip waterstop 2, a second driving cylinder 56 is fixedly installed on the surface of one side of the support frame 3 close to the corridor segment 1, and another pneumatic clamp 5 is installed at one end of the piston rod of the second driving cylinder 56. Since the second driving cylinder 56 is fixed on the support frame 3, the pneumatic clamp 5 connected to it cannot move linearly left and right on the surface of the support frame 3. Therefore, when the piston rod of the second driving cylinder 56 is extended to drive the pneumatic clamp 5 to contact and clamp the surface of the strip waterstop 2 and the corridor segment 1, it can effectively prevent the strip waterstop 2 from shifting in position.

[0058] In order to fit the strip waterstop during the installation process, the fixing mechanism also includes telescopic cylinders 62 distributed in a rectangular array and installed on the side of the support frame 3 away from the corridor segment 1. The inner wall of the connecting sleeve 46 is slidably clamped with a connecting shaft 63. One end of the connecting shaft 63 extends out of the connecting sleeve 46 and is fixedly sleeved with the inner wall of the circular plate 6. The extension of the piston rod of the telescopic cylinder 62 drives the connecting shaft 63 connected to it to move along the inner wall of the connecting sleeve 46. The movement of the connecting shaft 63 drives the circular plate 6 to move, thereby driving the arc block 61 to move, so that the arc block 61 squeezes the strip waterstop 2, which facilitates the close contact between the strip waterstop 2 and the joint of the corridor segment 1.

[0059] By setting up a clamping mechanism and a fixing mechanism, the installation of the joint between the strip waterstop 2 and the corridor segment 1 is simpler, the construction is convenient, and a lot of labor and time costs are saved. The arc-shaped block 61 on the circular plate 6 is used to approach the corridor segment 1 to connect the strip waterstop 2 to the corridor segment 1. At the same time, the extension of the piston rod of the push cylinder 415 drives the pneumatic clamp 5 to clamp the strip waterstop 2, and the pneumatic clamp 5 is driven to move under the action of the screw 52, ​​which is convenient for pulling the strip waterstop 2 to fit the corridor segment 1, thereby reducing labor costs.

[0060] Working principle: When in use, firstly, the joint surface of the pipe gallery segment 1 is cleaned by the cleaning mechanism to ensure that the surface is free of dust, and then the push cylinder 415 is started, and the connecting plate 414 connected thereto is driven to move by extending the piston rod of the push cylinder 415, and the movement of the connecting plate 414 drives the heat dissipation housing 411 and the square tube 413 to move, and the movement of the square tube 413 drives the nozzle 4 to move, so that the nozzle 4 is close to the joint of the pipe gallery segment 1, and then the motor 48 and the blowing box 41 are driven, and the gas enters the square tube 413 through the folded pipe 42 through the blowing box 41, and is sprayed out from the nozzle 4 to clean the joint surface of the pipe gallery segment 1, and then the air is driven to enter .... The rotation of the output shaft of the driving motor 48 drives the driving gear 49 connected thereto to rotate, and the rotation of the driving gear 49 drives the driven gear 410 meshing therewith to rotate, and the rotation of the driven gear 410 drives the connecting sleeve 46 connected thereto to rotate, and the rotation of the connecting sleeve 46 drives the sprocket 47 connected thereto to rotate, and the rotation of the sprocket 47 drives the chain 45 to rotate, thereby rotating the other sprockets 47, and the rotation of the chain 45 drives the slider 44 to slide along the surface of the limiting frame 43, thereby driving the nozzle 4 to move, and in the process of the movement of the nozzle 4, the slider 44 cooperates with the rotating nozzle 4, so that the nozzle of the nozzle 4 is always aligned with the joint of the pipe gallery segment 1;

[0061] After the cleaning is completed, the nozzle 4 is reset, and then the strip water stop 2 is placed at the joint of the pipe gallery segment 1 according to the predetermined position, and is tightly fixed to the pipe gallery segment 1 through the metal insert 22, and then the telescopic cylinder 62 is started in sequence according to the position of the strip water stop 2, and the connecting shaft 63 connected to it is driven to move along the inner wall of the connecting sleeve column 46 by the extension of the piston rod of the telescopic cylinder 62, and the movement of the connecting shaft 63 drives the circular plate 6 to move, thereby driving the arc block 61 to move, so that the arc block 61 squeezes the strip water stop 2, so as to make the strip water stop 2 and the joint of the pipe gallery segment 1 in close contact;

[0062] At the same time, the first driving cylinder 55 is started according to the position of the strip waterstop 2. The extension of the piston rod of the first driving cylinder 55 drives the pneumatic clamp 5 connected thereto to approach the joint of the corridor segment 1 and the strip waterstop 2 and clamp them. Then the reduction motor 53 on the pneumatic clamp 5 is started. The rotation of the output shaft of the reduction motor 53 drives the screw 52 connected thereto to rotate. The rotation of the screw 52 drives the T-shaped block 54 connected thereto to move along the inner wall of the groove 51. The movement of the T-shaped block 54 drives the first driving cylinder 55 and the pneumatic clamp 5 connected thereto to move, thereby pulling the strip waterstop 2 to move, reducing the time cost of manual adjustment and reducing labor costs at the same time.

[0063] When the two ends of the strip water stop 2 are in contact with the pneumatic clamp 5 on the second driving cylinder 56 and the pneumatic clamp 5 at the bottom of the support frame 3 respectively, the reduction motor 53 on the pneumatic clamp 5 is started, so that the pneumatic clamp 5 drives one end of the strip water stop 2 to approach the other end, and the two ends of the strip water stop 2 are fixed together by hot melting;

[0064] Then fill the expansion type sealing material 23 into the gap between the strip water stop 2 and the joint of the pipe gallery segment 1 to complete the installation.
