Description

Technical Field

[0001] The invention relates to the technical field of shield tunnel construction, and in particular to a slag transfer facility during shield tunnel construction and a use method thereof. Background Art

[0002] As a method of underground excavation construction, the shield method is not restricted by terrain, landform, river water conditions, etc. It has the advantages of high safety, fast construction speed, less impact on the environment, and flexible line selection. It has been widely used in the construction of subway tunnel projects passing through urban core areas or sensitive areas.

[0003] During the shield tunnel construction process, the excavated soil and debris cut by the shield machine cutter head needs to be transported to the outside of the tunnel using transfer facilities. During the soil transfer process, when the transfer facilities pass through complex terrain such as sharp turns and inclined ground, the soil and debris in the truck bed can easily slip off the truck bed, affecting the loading capacity of the transfer facilities and threatening the safety of on-site construction personnel and equipment.

[0021] The present invention is further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0022] like Figures 1 to 9 As shown, a slag transfer facility during shield tunnel construction period includes a bottom plate structure 1; the bottom plate structure 1 includes a bottom plate 101, a universal wheel 105 is arranged at the bottom of the bottom plate 101, and a truck box 204 is fixedly connected to the top of the bottom plate 101; a baffle structure 2 is arranged on the outer side of the truck box 204.

[0023] like Figure 1 As shown in FIG. 1 , the bottom plate structure 1 is the foundation part of the slag transfer facility during the shield tunnel construction period. Figure 1 As shown. It includes an L-shaped bottom plate 101, and the bottom plate 101 includes a horizontal plate and a vertical plate vertically arranged on the horizontal plate. The bottom of the horizontal plate is fixedly connected to a number of symmetrically distributed universal wheels 105, so that the entire device can be flexibly moved in the tunnel. Two symmetrically arranged handrails 102 are fixedly connected to the vertical plate, and a push rod 103 is fixedly connected between the handrails 102, which is convenient for the operator to push or pull the device. A bucket 204 is fixedly connected to the top of the bottom plate 101, which is used to load the debris excavated during the shield tunnel construction process. A cross bar 5 is also arranged below the push rod 103, and both ends of the cross bar 5 are fixedly connected to the handrail 102 to increase the stability of the overall structure.

[0024] Preferably, a non-slip pad 4 made of flexible material is fixedly connected to the outside of the push rod 103, and a plurality of grooves are symmetrically arranged on the outer surface of the push rod 103, thereby improving the comfort and safety of holding.

[0025] The baffle structure 2 includes a baffle 201 with a limiting hole 202, and the outer side of the truck bucket 204 is threadedly connected to a first screw rod 104; the baffle 201 forms a sliding connection with the first screw rod 104 through the limiting hole 202, and the cooperation between the first screw rod 104 and the limiting hole 202 enables the baffle 201 to be adjusted and fixed at different positions on the truck bucket 204.

[0026] The baffle structure 2 is intended to prevent the dirt from sliding off the bucket 204 when transporting on complex terrain. Figure 2 , 3 As shown. The baffle 201 adopts a U-shaped structure, which surrounds and fits the three sides of the bucket 204, providing effective lateral protection. Two limiting holes 202 are provided on the three outer sides of the baffle 201. These limiting holes 202 are U-shaped structures, which form a sliding connection with the first screw rods 104 set on the bucket 204. The six first screw rods 104 are respectively fixed on the three outer sides of the bucket 204 through threaded connection, allowing the baffle 201 to adjust its height as needed.

[0030] The stabilizing structure 3 is to ensure that the device is in good contact with the ground in a static state and improve stability, and includes two symmetrically arranged bases 301, one side of each base 301 is fixedly connected to the bottom plate 101. The base 301 is rotatably connected to the tripod 303 through a second screw 302, and the tripod 303 can rotate relative to the base 301.

[0031] The tripod 303 is sleeved on the outside of the skateboard 306 and is fastened to the skateboard 306 by a third screw 304. Specifically, the stabilizing structure 3 also includes a third screw 304 for limiting the relative sliding of the skateboard 306 and the tripod 303. The skateboard 306 and the tripod 303 are provided with corresponding screw holes 305. The third screw 304 is provided on the skateboard 306 and the tripod 303 and cooperates with the screw hole 305, so that the skateboard 306 can be adjusted and fixed at different positions on the tripod 303.

[0032] The connecting end of the slide plate 306 and the foot pad 309 is installed with a fourth screw rod 307 through a threaded hole, and the bottom end of the fourth screw rod 307 is fixedly connected to the foot pad 309. The foot pad 309 is internally movably connected with a limit pin 7 for being nailed into the ground to enhance the stability of the device.

[0033] The fourth screw rod 307 is provided with a spring 8 on its outer sleeve, and the spring 8 is located between the bottom of the plug 308 and the top of the slide plate 306, so as to provide additional buffering effect and reduce the impact of vibration on the device.

[0034] A method for using a slag transfer facility during shield tunnel construction, which is applied to the slag transfer facility during shield tunnel construction as described above, comprises the following steps: Step 1: before loading the excavated soil from the shield machine, move the bucket 204 to a predetermined position, rotate the footrest 303 to a suitable angle, stretch the length of the slide plate 306, and then fix the length of the slide plate 306, rotate the fourth screw 307 to lower the foot pad 309 to a height that fully fits the ground, nail the limit nail 7 into the ground in the tunnel, stabilize the position of the device, and load the soil into the bucket 204; Specifically, the operator holds the anti-skid pad 4 on the outside of the push rod 103 and moves the bucket 204 to a predetermined position through the universal wheel 105 at the bottom of the bottom plate 101. Then, the second screw rod 302 is rotated counterclockwise to loosen the tripod 303, rotate it to a suitable angle, stretch the length of the slide plate 306, and fix the position of the slide plate 306 through the third screw rod 304. Then, the fourth screw rod 307 is rotated clockwise to lower the foot pad 309 to a height that fully fits the ground, and finally the limit nail 7 is nailed into the ground to stabilize the position of the device.

[0035] Step 2: After the slag is loaded, pull up the limit pin 7 to a height clear of the ground, loosen the fourth screw 307, retract the slide 306 and rotate the slide 306 and the tripod 303 to a position where one side of the tripod 303 is in contact with the bottom plate 101, fix the angle of the tripod 303, loosen the first screw 104, move the baffle 201 up to the required height, block the slag in the truck bed 204, tighten the first screw 104 to fix the baffle 201, and pull the truck bed 204 for transportation.

[0036] Specifically, after the slag is loaded in the truck bed 204, the limiting nail 7 is pulled up, the slide plate 306 is retracted, and the slide plate 306 and the tripod 303 are rotated to be close to the bottom plate 101. After fixing the angle of the tripod 303, the first screw 104 is rotated counterclockwise to move the baffle 201 up to the required height for blocking, and then the first screw is rotated clockwise to fix the position of the baffle 201. After that, the device is pulled by the universal wheel 105 for safe transportation. When encountering complex terrain, the baffle 201 can effectively prevent the slag loaded in the truck bed 204 from sliding down, ensuring the safety and efficiency of slag transportation.

[0037] In general, through the above-mentioned specific implementation methods, the present invention provides an efficient and safe solution for the transportation of slag during the construction period of a shield tunnel, which is particularly suitable for the transportation of slag under complex terrain conditions in the tunnel during the construction period of a shield tunnel.
