Description

Technical Field

[0001] The present invention relates to the technical field of on-site assembly construction of prefabricated pipe corridors, and in particular to a pipe segment splicing device and a splicing method for an assembled pipe corridor. Background Art

[0002] At present, the construction of urban underground integrated pipeline corridors mostly adopts the construction method of slope excavation and cast-in-place support. This method has disadvantages such as large on-site workload, difficulty in ensuring the quality of on-site casting of pipeline corridors, and great impact on the surrounding environment. Recently, the construction method of prefabrication in the factory, transportation of pipeline corridors, and on-site assembly and tensioning has become popular. This method uses excavators for slope excavation on site, and the pipeline corridors are transported by conventional trailers, truck cranes or crawler cranes for lifting.

[0003] During the on-site assembly and tensioning of prefabricated pipe corridors, the steel cables used to hoist the pipe segments are relatively long, so the segments are prone to self-rotation or deflection during movement. This results in a large discrepancy between the deflection angle and the theoretical installation angle when the assembly position is lowered. At this point, the hoisting personnel need to cooperate with the adjustment personnel at the pipe segment to perform manual adjustments. However, due to the large tonnage of the prefabricated pipe corridor, the double-compartment pipe segments can reach 30-50 tons. This adjustment process can easily pose a safety hazard to surrounding workers, and manual correction will still result in local errors. It is also easy for the segments to collide with already assembled pipe segments, resulting in low assembly accuracy and efficiency. Summary of the Invention

[0019] A method for splicing a pipe segment splicing device of an assembled pipe gallery, comprising the following steps:

[0020] Step 1: Before use, the fixed mounting frame is used for tunnel excavation in the front, and multiple splicing cylinders set at the rear end of the fixed mounting frame are extended to push the assembly pipe section at the rear to complete the assembly, so that the fixed mounting frame moves forward. The fixed mounting frame drives the adjustment mechanism in front of the assembly pipe section to move forward the distance of one assembly pipe section.

[0021] Step 2: After the advancement is completed, the cushion layer is laid, and the cushion base material is added to the inside of the scattering box. The protective end cover installed on the top of the scattering box is closed, and the scattering motor installed on the surface of the scattering box drives the scattering screw to rotate. The scattering screw stirs the material inside the scattering box to make the material fully mixed to avoid the material from solidifying. The laying of the material inside the scattering box is controlled by controlling the scattering valve at the lower end of the scattering box. The material is laid between the fixed mounting bracket and the previous assembly pipe section through the scattering hose installed at the outlet at the lower end of the scattering box. The surface of the scattering hose is elastically connected to the surface of the fixed mounting bracket through a tension spring to avoid interference caused by contact between the surface of the scattering hose and the bottom. Multiple scattering hoses inject the sprayed material into the diverter trough, and the diverter cylinder installed on the surface of the guide shaft drives the diverter baffle to block the diverter trough. After the material is full, the diverter baffle is opened to allow the material to be evenly laid horizontally.

[0022] Step three: At the same time, two paving cylinders provided on the surface of the fixed mounting frame extend out to drive the mounting plate at the output end to move. The surface of the mounting plate is slidably connected to the surface of the fixed mounting frame through two guide shafts. The mounting plate is fully extended along the direction of the guide shaft. The surface of the mounting plate is fixedly connected to the surface of the diverter trough, driving the diverter trough to move synchronously for moving and spreading materials. The paving scraper provided on the output end of the lifting cylinder is driven by multiple lifting cylinders provided on the surface of the mounting plate to descend to the designated position for paving. The descending paving scraper is driven by the paving cylinder to move toward the fixed mounting frame to spread and level the material sprayed by the spreading hose.

[0023] Step 4: After the cushion layer is paved, the assembly pipe section is set up. The crane lifts the assembly pipe section along the assembly direction to the top between the fixed mounting frame and the previous assembly pipe section through the lifting ring provided above the assembly pipe section. The assembly pipe section is provided with a sealing groove and one end of the rubber strip is close to the previous assembly pipe section. The assembly pipe section is lifted to between the fixed mounting frame and the previous assembly pipe section. The assembly pipe section rotates due to external force during the lifting process and cannot be aligned with the previous assembly pipe section, making it inconvenient to put it into the tunnel for assembly. The multiple adjustment hydraulic cylinders provided on the surface of the fixed mounting frame are driven. The adjustment hydraulic cylinder drives the adjustment mounting seat to flip through the adjustment connecting plate. The cam is moved upwards to move the two traction brackets in the opposite direction along the axis of the adjusting screw by adjusting the motor provided on the surface of the mounting seat, and the position of the traction bracket is adjusted. The outer wall of the assembling pipe segment is placed inside the traction bracket, and the outer surface of the assembling pipe segment is connected to the guide pulley provided on the surface of the traction bracket, and the assembling pipe segment is adjusted to an aligned state. The clamping motor provided on the surface of the traction bracket drives the movable clamping plate to slide along the surface of the clamping groove, and the surface of the traction bracket and the surface of the movable clamping plate are in contact with the inner wall of the assembling pipe segment through the guide pulley, so that the position of the assembling pipe segment is clamped and guided to be lowered.

[0024] Step 5: After clamping the assembly pipe segment, slowly hoist it and place it on top of the cushion layer. Adjust the hydraulic cylinder to drive the adjustment mounting seat to flip synchronously. After placing it on the cushion layer surface, adjust the hydraulic cylinder to drive the adjustment mounting seat to retract it. Test-fit the connection block of the assembly pipe segment with the connection block set at the proximal end of the previous assembly pipe segment. The test-fitting is completed when the bolts can pass through the connection holes opened on the surfaces of the two connection blocks in turn. Through the multiple assembly cylinders set on the surface of the fixed mounting frame, the output end of the assembly cylinder extends out through the splicing pad to push the assembly pipe segment backward, and the rubber strip between the two assembly pipe segments is compressed synchronously. After the assembly width meets the design requirements, the bolts are installed and tightened in stages in sequence, and the next assembly pipe segment is spliced.

[0025] The beneficial effects of the present invention are:

[0026] By setting up an adjustment mechanism and a splicing mechanism, the adjustment mechanism adjusts the assembly position through a traction bracket, and the splicing mechanism adjusts the assembly tightness through a splicing cylinder, thereby solving the technical problem of being inconvenient to adjust the assembly accuracy and assembly sealing of the existing prefabricated pipe gallery during on-site assembly and tensioning construction.

[0058] A method for splicing a pipe segment splicing device of an assembled pipe gallery comprises the following steps:

[0059] Step 1: Before use, the fixed mounting frame 1 is used for tunnel excavation in the front, and the multiple splicing cylinders 3 set at the rear end of the fixed mounting frame 1 are extended to push the assembly pipe section 301 at the rear to complete the assembly, so that the fixed mounting frame 1 moves forward. The fixed mounting frame 1 drives the adjustment mechanism in front of the assembly pipe section 301 to move forward the distance of the assembly pipe section 301.

[0060] The second step is to lay the cushion layer, add cushion layer materials to the inside of the material spreading box 314, close the protective end cover 310 provided on the top of the material spreading box 314, and drive the material spreading screw 312 to rotate through the material spreading motor 311 provided on the surface of the material spreading box 314, and the material spreading screw 312 stirs the material inside the material spreading box 314 so that the material is fully mixed to prevent the material from solidifying.

Multiple spreading hoses 315 inject the sprayed material into the diverter groove 308. The diverter cylinder 323 set on the surface of the guide shaft 319 drives the diverter baffle 313 to block the diverter groove 308. After the material is full, the diverter baffle 313 is opened to allow the material to be evenly laid horizontally.

[0061] Step three: At the same time, two paving cylinders 317 provided on the surface of the fixed mounting frame 1 extend out to drive the mounting plate 318 at the output end to move.

The mounting plate 318 is fully extended along the direction of the guide shaft 319. The surface of the mounting plate 318 is fixedly connected to the discharge ends of multiple spreading hoses 315, driving the spreading hoses 315 to move and spread materials.

[0062] Step 4: After the cushion layer is paved, the assembly pipe segment 301 is set up. The crane lifts the assembly pipe segment 301 along the assembly direction to the top between the fixed mounting frame 1 and the previous assembly pipe segment 301 through the lifting ring 305 provided above the assembly pipe segment 301.

During the lifting process, the assembly pipe segment 301 is rotated by external force and cannot be aligned with the previous assembly pipe segment 301, which is not convenient for being placed in the tunnel for assembly. The multiple adjustment hydraulic cylinders 201 provided on the surface of the fixed mounting frame 1 are driven. The adjusting hydraulic cylinders 201 drive the adjustment mounting seat 203 to move forward through the adjusting connecting plate 202. The line is flipped over and approaches the assembly pipe section 301 hoisted above. The adjusting motor 206 provided on the surface of the adjusting mounting seat 203 drives the two traction brackets 2 to move in opposite directions along the axial direction of the adjusting screw 205 to adjust the position of the traction bracket 2, and the outer wall of the assembly pipe section 301 is placed into the interior of the traction bracket 2. The outer surface of the assembly pipe section 301 is connected to the guide pulley 211 provided on the surface of the traction bracket 2, and the assembly pipe section 301 is adjusted to an aligned state. The clamping motor 210 provided on the surface of the traction bracket 2 drives the movable clamping plate 208 to slide along the surface of the clamping groove 207. The surface of the traction bracket 2 and the surface of the movable clamping plate 208 are in contact with the inner wall of the assembly pipe section 301 through the guide pulley 211, and the position of the assembly pipe section 301 is clamped and guided to be lowered;

[0063] After the assembling pipe section 301 is clamped, it is slowly hoisted and placed on the top of the cushion layer. The adjusting hydraulic cylinder 201 drives the adjusting mounting seat 203 to flip synchronously. After it is placed on the cushion layer surface, the adjusting hydraulic cylinder 201 drives the adjusting mounting seat 203 to be retracted. The connecting block 303 of the assembling pipe section 301 is tested with the connecting block 303 set at the proximal end of the previous assembling pipe section 301. The bolts can pass through the connecting holes 304 opened on the surfaces of the two connecting blocks 303 in turn, and the test is completed. By fixing the multiple assembling oil cylinders set on the surface of the mounting frame 1, the output end of the assembling oil cylinder extends out through the splicing pad 322 to push the assembling pipe section 301 backward, and the rubber strip 307 between the two assembling pipe sections 301 is compressed synchronously. After the assembling width meets the design requirements, the bolts are installed and tightened in stages in sequence, and the next assembling pipe section 301 is spliced.
