[0021] Example 1: Please refer to Figures 1-4 A temporary sealing and water-stopping device for pipe jacking construction includes a sealing rubber ring 1, a concrete gate groove 7 and a pipe hole 12. Steel gate grooves 5 are installed inside both sides of the concrete gate groove 7, and a gate body 8 is installed between the inner sides of the steel gate grooves 5. Lifting lugs 6 are connected to both sides of the top of the gate body 8. A pipe hole 12 is provided at one end of the concrete gate groove 7, and a sealing rubber ring 1 is installed on the inner wall of the gate body 8 at one end of the pipe hole 12.

[0022] Both sides of the inner wall of the concrete gate slot 7 are evenly equipped with embedded parts 10, and one end of each embedded part 10 is embedded into the inner side of the concrete gate slot 7. One end of each embedded part 10 is welded and fixed to the steel gate slot 5.

[0023] The inner sides of the concrete gate slot 7 and the steel gate slot 5 are filled with secondary grout 4, and the material of the secondary grout 4 is concrete.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when using this structure, the concrete gate slot 7 is reliably connected to the embedded part 10 via the steel gate slot 5. The steel gate body 8 is installed inside the steel gate slot 5. The gap between the gate body 8 and the concrete gate slot 7 is sealed with a sealing rubber ring 1 to achieve a water-stopping effect. This device eliminates the need to install a hoist, and there is no need to install a series of accessories for opening and closing the gate body 8, such as the gate body 8 support frame and operating rod. It simplifies the process and is especially suitable for construction environments with limited time requirements.

[0025] Example 2: The inner wall of the steel gate slot 5 is provided with a limit groove 3, and the outer walls of both ends of the gate body 8 are movably connected to the sealing rubber ring 1 through the limit wheel 2;

[0026] The outer wall of one end of the gate body 8 is evenly provided with mounting holes 11, and screws 9 are installed on the inner side of each mounting hole 11. The screws 9 are symmetrical about each other with respect to the center point of the gate body 8.

[0027] Both sides of one end of the concrete gate slot 7 are pre-embedded with embedded sleeves 13, and the inner side of the embedded sleeves 13 is provided with internal threads.

[0028] One end of each screw 9 extends to the inner side of the embedded sleeve 13, and a threaded connection structure is formed between the screw 9 and the embedded sleeve 13.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using this structure, only two lifting lugs 6 on the gate body 8 are used for installation and subsequent disassembly. Disassembly is convenient; only a crane is needed to lift the steel gate body 8 out. The gate body 8 can be reused, and the only loss is the steel gate slot 5. The cost is low and it can be used for short, medium and long-term temporary blocking. This technology does not require operation and maintenance or power supply during construction. Disassembly and assembly can be done with only a crane, and the steel gate body 8 can be recycled.

[0030] Working principle: When using this device, firstly, after the strength of the embedded part 10 reaches the required level, weld the steel gate slot 5. Control the welding quality during construction and reliably connect the steel gate slot 5 with the embedded part 10. After connection, seal the upper and lower gaps with templates, pour the secondary grouting 4, and pour the concrete on both sides of the jacking pipe opening. Control the pouring quality during the pouring process. Pass the lifting rope through the lifting lug 6 and adjust the verticality of the sealing surface of the gate body 8. By adjusting the screws 9 at the four corners of the gate body 8, make the verticality error of the sealing surface of the gate body 8 less than 1 / 1000mm. After checking the tilt of the gate body 8 in the left and right directions again, use shims to support the screws 9 at the four corners and tighten the screws 9 to fix them.

[0032] Step 1: The concrete gate slot 7 is then reliably connected to the steel gate slot 5 and the embedded part 10. The steel gate body 8 is installed in the steel gate slot 5. The gap between the gate body 8 and the concrete gate slot 7 is sealed with a sealing rubber ring 1 to achieve the water-stopping effect.

[0033] Step 2: This device eliminates the need to install a gate hoist, and does not require the installation of a series of accessories for opening and closing the gate body 8, such as the gate body 8 support frame operating rod. It simplifies the process and is especially suitable for construction environments with limited time requirements.

[0034] Implementation steps for the second innovation point:

[0035] Step 1: The two lifting lugs 6 on the gate body 8 are used for installation and subsequent disassembly. Disassembly is convenient; the steel gate body 8 can be lifted out using a crane.

[0036] Step 2: The gate body 8 is reusable, with only the steel gate slot 5 being damaged. It is low in cost and can be used for short, medium and long-term temporary blocking. This technology does not require operation and maintenance or power supply during construction. Disassembly and assembly can be done with just a crane. The gate body 8 is also recyclable.
