[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] A method for transporting and positioning a pipe gallery module specifically includes the following steps:

[0035] S1: Select a transport vehicle according to the pipe gallery module (select a suitable transport vehicle - SPMT self-propelled modular transporter by integrating the basic information of all pipe gallery modules. Because it is flexible to use, convenient for loading and unloading, and the load capacity can reach more than 50,000 tons in the case of multi-vehicle mechanical assembly or free combination; the vehicle model used in this project is the K-25 KAMAG self-propelled modular transporter, the width of a single-axle vehicle is 3000 mm, the length is 1500 mm, the body height is 1175 mm, the maximum lifting height is 1475 mm, the minimum lowering height is 875 mm, the net load of a single-axle vehicle is 41.7 t, the self-weight is 3.3 T, and the total load of a single-axle vehicle reaches 45 T; since the U201 pipe gallery module is 40 meters long and 10 meters wide, two SPMT transport vehicles are used in parallel. Each transport vehicle is spliced by 22 single-axle vehicles, with a total of 44 single-axle vehicles and 2 power units), prefabricate transport supports, then lay isolation parts on the transport vehicle, and then install the transport supports on the transport vehicle (the design drawing of the module transport support is determined by the AP structure design engineer according to the size, weight of the pipe gallery module and the selected transport trailer type, and is divided into three sections for convenient processing and transportation to the pipe gallery module prefabrication site; the transport support is trapezoidal, with an upper width of 8000 mm, a lower width of 3500 mm, and a height of 2175 mm; the transport support is divided into three sections A, B, and C, with a total length of 32 meters; these three sections of transport supports can be assembled in different orders according to the types of the transported pipe gallery modules and can be simultaneously applicable to two different sizes of pipe gallery modules, namely U201 and U202; before the transport support is loaded onto the vehicle, a 36-mm-thick wooden board (the wooden board refers to the isolation part) needs to be laid on the transport vehicle for isolation protection, and then it is hoisted and placed on the SPMT transport vehicle in sequence according to the order of different modules, and fastened with high-strength bolts).

[0036] S2: Calculate the transport data to obtain the maximum tipping angle of the transport vehicle and plan the transport route;

[0037] Among them, the total load of the transport trailer is 45 T 44 = 1980 T; the self-weight of the transport trailer is 176 T, the weight of the power unit is 6 T, the transport support and the auxiliary materials of the scaffolding are about 250 T, and the self-weight of the pipe gallery module is about 444 T. Therefore, the total load is 176 + 6 + 250 + 444 = 876 T; the single-axis load is 876 / 44 = 19.91 T. There are 8 groups of tires for the single axis, and the load of a single group of tires is 19.91 / 8 = 2.49 T; the transport load ratio is 876 / 1980 = 44.24%. The maximum tipping angle of the transport trailer calculated by the software model according to the module size, weight, center of gravity, and the weight of the trailer and the transport support in the AP design is 34.33 degrees. Safety calculations are carried out to ensure safety during transportation;

[0038] Priority is given to selecting a route with good road conditions and gentle slopes; if there is a bridge-crossing device on the way, the transport height of the pipe gallery module should be less than 0.5 m below the height limit of the bridge-crossing device to ensure a certain safe passing distance; simulate the selected route on Google Maps according to the size of the pipe gallery module and the transport trailer, and depict and calculate the turning radius size and schematic diagram of each intersection, preliminarily verify whether the road width of the selected route meets the transport requirements, and whether the turning radius of the transport vehicle is met at the turning intersections. Calculate which intersections need to be paved with hardened road surfaces and clear obstacles according to the turning radius of the transport vehicle; then conduct on-site surveys on the simulated route and key positions, take photos of the positions that need to be rectified, and uniformly report to the AP for coordination and solution.

[0039] S3: Fix the pipes on the pipe gallery module, remove the full hall scaffold on the first floor of the pipe gallery module and the auxiliary passage scaffolding around the pipe gallery module, and then remove the unnecessary cantilever platform scaffolding according to the maximum size of the height and width limits for module passage;

[0040] Among them, there are mainly three ways to fix the pipes on the pipe gallery module;

[0041] For pipes with a smaller diameter, to prevent the pipes from moving horizontally or shaking up and down during transportation, they are fixed to the steel structure crossbeam by bundling with a scaffold, and the pipes are wrapped with soft protection materials;

[0042] For pipes with a larger diameter, if formal welding brackets have been installed on the pipes, the pipe brackets are temporarily fixed to the steel structure beam by welding temporary L-shaped stiffeners. At the same time, a lashing chain or lashing belt is added every 10 meters to fix the pipes to the steel structure beam. If a lashing chain is added, soft protection materials need to be wrapped on the pipe surface and the steel structure surface;

[0043] For suspended pipes or large-sized elbows, they are fixed to the nearby steel structure by using a sling and a chain block.

[0044] S4: Calculate the ground elevation of the pipe gallery module, level the ground under the pipe gallery module according to the calculated value, and lay roadbed plates;

[0045] Among them, the body height of the SPMT transport vehicle is 1175 mm, the theoretical maximum lifting height is 1475 mm, and the theoretical minimum lowering height is 875 mm. Considering that the transport vehicle may not actually reach the limit value of the theoretical lifting and lowering, the limit values of the lifting and lowering heights are reduced by 55 mm during the calculation. Therefore, the maximum lifting height is 1420 mm, and the minimum lowering height is 930 mm; The first step is to calculate the state when the transport vehicle enters under the pipe gallery module at the actual lowest height of the vehicle body; When the transport vehicle enters under the pipe gallery, a safety distance of 60 mm needs to be reserved. The lowest height of the transport vehicle is 930 mm, the height of the transport support is 2175 mm, and the thickness of the two-layer isolation protection wooden formwork on the upper and lower surfaces of the transport support is 36 mm + 36 mm. From this, the height from the upper surface of the subgrade slab to the lower surface of the main beam is 3237 mm; The height from the lower surface of the main beam to the upper surface of the column base plate is 3059 mm, the thickness of the column base plate is 55 mm, and the thickness of the subgrade slab is 100 mm. From this, the ground elevation can also be calculated to be 223 mm below the column base plate (please refer to Figure 1 ); The second step is to calculate the state when the transport vehicle rises to the actual highest height of the vehicle body after entering under the pipe gallery module; The maximum height of the transport vehicle is 1420 mm. Adding the thickness of the two-layer wooden formwork and the height of the transport support, the height from the upper surface of the subgrade slab to the lower surface of the main beam can be calculated to be 3667 mm; The shear key length of the column base plate is 150 mm, the screw of the anchor bolt is 177.5 mm higher than the concrete foundation surface, and the height from the concrete foundation surface to the subgrade slab is 123 mm. Therefore, it can be calculated that the lowest point of the shear key of the pipe gallery module column base plate is still 102.5 mm higher than the highest point of the screw of the anchor bolt. Through the above theoretical calculations, it can be obtained that the ground elevation that needs to be leveled by TCF is based on 223 mm below the column base plate (please refer to Figure 2 );

[0046] According to the calculated data, water treatment is carried out on the ground inside the pipe gallery module, and then a small bulldozer is used to level the ground under the pipe gallery module. The wire-pulling method is used to check whether the ground elevation after treatment is consistent; In this project, 100-mm-thick DURA-BASE® advanced composite pads are used as subgrade slabs. These composite pads are made of high-performance thermoplastics, have a strong and durable, uniform surface. The tread pattern improves the safety and traction of load-bearing vehicles, and the interlocking system reduces the chance of drift and slip; The size of a single subgrade slab is 2440 mm x 4270 mm x 100 mm, weighing about 454 Kg. Adjacent pads are lap-jointed, and each pad is equipped with 16 slots. The locking pins are inserted into the slots and rotated 90 degrees with professional tools to lock and fix the adjacent pads to each other.

[0047] S5: The transport vehicle moves to the roadbed under the tunnel module, and places isolation pieces (wooden boards) on the transport supports. When the transport vehicle lifts the tunnel module, the tunnel module is fixed, and the auxiliary detection mechanism is installed on the transport vehicle, and after it is in contact with the transport supports, it is transported.

[0048] Among them, the walking position lines of the transport vehicle tires are marked on the surface of the roadbed slab from the center of the axle columns on both sides of the corridor module to the inner symmetrical position, so that it can quickly enter the center position under the corridor module. Since the transport support has an installation direction, the correct installation direction can ensure that there will be a corresponding vertical support beam of the transport support directly below each main beam of the corridor module. Therefore, when the transport vehicle enters under the corridor module, it must be positioned in the correct direction; after the module is in place, it is necessary to lay wooden boards on the upper surface of the transport support beam and the contact position of the main beam of the corridor module for isolation and protection, and tie them with thin wire to prevent slipping; when the transport vehicle is lifted until the wooden boards are pressed tightly, start to fix the corridor module and the transport vehicle; 11 sealing chains are used on both sides of the transport vehicle as follows Figure 3 Shown in The chain is installed and tightened at the position. Each car sealing chain is 8 meters long and can withstand a tensile force of 5 tons. Two temporary gantries are used to fix the main beams in front and behind the corridor module to prevent it from sliding forward and backward.

[0049] Before the transportation of the tunnel module, the AP design engineer, AP module manager, QA / QC, transportation manager, road manager, and AP project manager need to jointly issue a transportation approval (the issuance process is: module inspection application → AP module manager accepts the application → organizes the inspection and records the final items → AP issues the final items → construction clears the final items → AP checks and closes the final items → AP issues the module transportation approval);

[0050] Before transporting the tunnel module, the levelness, height and fixing method of the transport vehicle must be checked before the module is transported; during the movement of the transport vehicle, in addition to the on-board driver and technical maintenance personnel, 4 flag bearers are required to direct passing vehicles and pedestrians on the left and right sides of the head and tail of the tunnel module; a vehicle with warning lights is equipped in front of the transport vehicle to lead and clear the way, and a vehicle with warning lights and extra-wide signs is equipped behind the transport vehicle to carry food and water for emergency preparation; in order to ensure the smooth transportation of the tunnel module, two groups of personnel are arranged to clear and restore roadblocks and protect isolation belts during transportation; when transporting the tunnel module, the transport vehicle must be driven at a uniform speed, with a maximum speed not exceeding 25Km / h, and a speed not exceeding 1Km / h on special roads and turns. The height of one side of the transport vehicle can be adjusted to ensure that the tunnel module remains horizontal; the vehicle should stop moving in severe weather such as rain or sandstorms.

[0051] S6: Calculate the elevation of the installation area. After processing the installation area of the pipe gallery module according to the calculated data, the transport vehicle transports the pipe gallery module to the installation area and then installs it.

[0052] Among them, the calculation is specifically as follows. The elevation calculation data of the ground at the ASU installation site can be deduced inversely according to the calculation method of the basic elevation data when the transport vehicle starts at the TCF. When the transport vehicle enters the installation position of the pipe gallery module at its actual maximum height, the maximum height of the transport vehicle is 1420 mm. When the lowest point of the shear key of the column base plate of the pipe gallery module is still 102.5 mm higher than the highest point of the anchor bolt screw, it can be calculated that the elevation of the ground that needs to be leveled at the ASU pipe gallery module installation site is based on 300.5 mm below the highest point of the anchor bolt screw.

[0053] Process the installation area, remove the obstacles within and near the on-site installation area of the pipe gallery module that may affect the passage of the transport vehicle, and sprinkle water and harden and level the ground at the pipe gallery module installation site. To reduce the number of times the transport vehicle adjusts its position, use the "fixed wire method" on the ground according to the distance from the outer edges of the tires on both sides of the transport vehicle to the center of the bolt holes on both sides of the column base plate of the pipe gallery module to determine the precise travel route of the transport vehicle. In this way, the pipe gallery module can be positioned in one go faster, and it is necessary to clean the surfaces of the grouting blocks on all concrete foundations and the screw rods of the anchor bolts.

[0054] During installation, when the transport vehicle enters the installation position of the pipe gallery module, adjust the position of the transport vehicle so that the center of the bolt holes on the column base plate of the pipe gallery module is basically aligned with the center of the anchor bolts on the concrete foundation. Then install the "bullet head". During the slow descent of the transport vehicle, at the same time, use the steel structure module installation and positioning device (including a jack and a jack fixing bracket) invented to adjust the column base plate with a large bolt hole deviation. Finally, make 80 anchor bolts pass through the bolt holes on the column base plate integrally and precisely.

[0055] Please refer to Figure 4 、 Figure 5 and Figure 6 , an auxiliary detection mechanism for transporting and positioning a pipe gallery module, which is used to assist a method for transporting and positioning a pipe gallery module, including: an installation box 1;

[0056] A moving part 2 is slidably arranged in the installation box 1. An elastic part 3 is installed between the installation box 1 and the moving part 2. A touch switch 6 is arranged in the installation box 1 (the moving part 2 will press the touch switch 6 during the movement). The touch switch 6 is electrically connected to a warning device (a sound and light alarm) through a wire. A slot 4 is opened in the installation box 1. A limiting part 5 is slidably arranged in the slot 4. An elastic element is installed between the slot 4 and the limiting part 5. The limiting part 5 is attached to the moving part 2 to prevent the moving part 2 from moving, and the limiting part 5 is located between the touch switch 6 and the moving part 2. The side of the limiting part 5 facing the moving part 2 is an inclined surface.

[0057] A second gear 17 is rotatably provided in the mounting box 1, and a moving rack 8 which is connected to the moving member 2 and meshes with the second gear 17 is slidably provided in the mounting box 1; a first gear 7 is provided on the second gear 17. The first gear 7 and the second gear 17 are on the same axis. A driving rack 9 is meshed with the first gear 7. One end of the driving rack 9 extends to the outside of the mounting box 1 and is connected to the contact member 10 (the driving rack 9 and the contact member 10 are hinged).

[0058] The working mode of the auxiliary detection mechanism is specifically as follows: the auxiliary limiting mechanism is installed on the transport vehicle, and the contact member 10 is in contact with the transport support member (and there are several groups of the auxiliary detection mechanisms installed on the transport vehicle, which are respectively arranged in the front, rear, left and right directions of the transport support member); during the transportation process, if the transport support member is offset or moved, it will push the auxiliary detection mechanism on the moving direction side, so that its contact member 10 moves with the driving rack 9, driving the second gear 17 to drive the first gear 7 to rotate synchronously, thereby driving the moving rack 8 and the moving member 2 to move closer to the touch switch 6. During this process, the moving member 2 will push the limiting member 5 into the slot 4 (because the side of the limiting member 5 facing the moving member 2 is an inclined surface, and during the movement of the moving member 2, it will squeeze the limiting member 5 to make it move into the slot 4) until the limiting member 5 completely enters the slot 4, so that the restriction of the limiting member 5 on the moving member 2 disappears; through the contraction of the elastic member 3, the moving member 2 is pulled to move and press the touch switch 6, so that the warning device is powered on to give a warning to prompt the staff, so that the staff can timely understand the abnormal situation and ensure the safety during the transportation process.

[0059] In this embodiment, as a further optimized solution, please refer to Figure 5 and Figure 6, a guide post 18 is provided on the second gear 17, the first gear 7 is rotatably sleeved on the guide post 18, and a fixing member 19 for fixing the first gear 7 is provided on the second gear 17 (the fixing member 19 refers to a fixing bolt, and a plurality of screw holes are provided in the second gear 17. The fixing bolt passes through the first gear 7 and is inserted into the screw hole to connect the first gear 7 and the second gear 17. By changing the screw hole where the fixing bolt is located, the first gear 7 can rotate to change the angle); a sliding groove 21 is provided on the driving rack 9, and the direction of the sliding groove 21 is the same as the moving direction of the driving rack 9. An installation member 20 is provided on the guide post 18, and the side of the installation member 20 away from the guide post 18 is slidably inserted into the sliding groove 21; disconnect the connection of the fixing member 19 to the first gear 7, rotate the first gear 7, so that the installation member 20 drives the driving rack 9 and the contact member 10 to rotate, for adjusting the angle of the contact member 10, so that the auxiliary detection mechanism is applicable to different usage requirements; and the installation member 20 is rotatably connected to the guide post 18, so that the installation member 20 can also rotate together during the rotation of the first gear 7, and a bolt is provided on the installation member 20 to fix itself; the installation member 20 is slidably inserted into the sliding groove 21, so that the driving rack 9 can drive the first gear 7 to rotate when moving.

[0060] In this embodiment, as a further optimized solution, please refer to Figure 5 , the diameter of the first gear 7 is larger than the diameter of the second gear 17, so that when the driving rack 9 moves, the moving rack 8 can move a greater distance (more than the driving rack 9), ensuring that the moving amplitude of the moving member 2 is larger, so that it can press the touch switch 6, and ensuring that the warning effect can be triggered.

[0061] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 7, a working box 11 is installed on the installation box 1. An activity plate 13 for sealing and dividing the inner cavity of the working box 11 is slidably arranged in the working box 11. An elastic support member 14 (such as a rubber or metal elastic member) is installed between the working box 11 and the activity plate 13; a switch is installed in the working box 11. When the activity plate 13 moves, it will press the switch, and the switch is electrically connected to the warning device through a wire. An air inlet 12 and an air outlet 16 are provided on the working box 11; during the driving process of the transport vehicle, external air will enter the working box 11 through the air inlet 12 and then be discharged from the air outlet 16 (the cross-sectional area of the air inlet 12 is larger than that of the air outlet 16); the faster the transport vehicle travels, the more air enters the working box 11, which will squeeze the activity plate 13, causing the activity plate 13 to move and press the switch to make the warning device emit a warning, which is used to prompt the staff to indicate that the speed of the transport vehicle is too fast at this time, playing a prompting role to ensure the safety during the transport process; a connecting pipe 15 is connected to the air outlet 16 so that the air outlet 16 is communicated with the slot 4; there are several air outlets 16, and the connecting pipe 15 is communicated with one of the air outlets 16 to introduce the air discharged from this air outlet 16 into the slot 4, which is used to push the limiting member 5 (a sealing treatment is carried out between the limiting member 5 and the slot 4 to avoid air leakage), increasing the pressure of the contact between the limiting member 5 and the moving member 2 (that is, increasing the friction force between the two), so that the moving member 2 will not move easily.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
