This invention utilizes hydraulic rods in conjunction with the steel formwork structure to form a stable support, effectively resisting construction vibrations and ensuring structural stability during concrete pouring, thus guaranteeing construction quality and safety. This invention, through modification of a conventional dump truck, allows for convenient on-site relocation and rapid deployment to unstable rock sections such as shallowly buried tunnel sections, weak and fractured zones, and fault zones. Especially in areas with a risk of sudden collapse, it can respond quickly and arrive at the work location promptly to carry out reinforcement work, exhibiting strong adaptability and high mobility.

Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, specifically relating to a rapid moving lining trolley for tunnel sidewall lining. Background Technology

[0002] In tunnel construction, the stability of the surrounding rock is crucial to construction safety and progress. Many tunnel projects traverse complex geological areas where the surrounding rock has poor self-stability and is prone to collapse and deformation. This is especially true in shallow buried sections, weak and fractured zones, and fault zones, where construction risks are even higher and sudden geological disasters are common, requiring timely reinforcement and support.

[0003] Traditional methods for localized tunnel lining reinforcement include cast-in-place concrete construction and precast component installation. Cast-in-place concrete requires the erection of fixed formwork and support frames, which is cumbersome, requires significant manpower and resources, has low formwork reuse rates, a long construction cycle, and is difficult to adapt to tunnel environments with varying geological conditions. While precast component installation is faster, the transportation of precast components is inconvenient, the cost is high, and the dimensions of precast components are difficult to perfectly match the lining requirements of complex geological conditions, easily leading to problems such as loose splicing and uneven stress, affecting the reinforcement effect. Therefore, there is an urgent need to develop a device that can quickly and flexibly respond to geological changes and effectively perform localized lining reinforcement. Utility Model Content

[0006] As a preferred technical solution, the automatic telescopic rod is a hydraulic cylinder.

[0007] As a preferred technical solution, the steel template has uniformly distributed reinforcing ribs vertically welded to the back of the main steel panel.

[0008] As a preferred technical solution, the reinforcing rib is an H-beam with a width and height of 200mm.

[0009] As a preferred technical solution, the spacing between the reinforcing ribs is 0.8 to 1.2 m.

[0010] As a preferred technical solution, the steel main panel is made of Q235B steel plate.

[0011] As a preferred technical solution, the steel main panel has a thickness of 0.05m, a width of 3m, and a length of 5m.

[0012] As a preferred technical solution, the top of the dump truck body is equipped with an operating platform, and one side is equipped with a pedestrian ladder connected to the operating platform.

[0014] This utility model is made by modifying a conventional dump truck, which is convenient to move to the construction site and can be quickly deployed to unstable surrounding rock sections such as shallow buried sections of tunnels, weak and fractured zones, and fault zones. Especially in areas with sudden collapse risks, it can respond quickly and arrive at the work position in time to carry out reinforcement work.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the following embodiments.

[0022] exist Figure 1 , 2 In this embodiment, the tunnel sidewall lining rapid moving lining trolley includes a dump truck 4, which is a 25t class truck with a cargo box length greater than 5m. A rectangular mounting plate 1 is vertically fixed to the side of the cargo box of the dump truck 4 through threaded fasteners. The mounting plate 1 is a rectangular reinforcing frame with a rectangular steel plate welded on it. The reinforcing frame is made of 20a channel steel. The rectangular steel plate has a thickness of 3cm, a length of 5.5m, and a width of 3.5m.

[0023] The mounting plate 1 is connected to the steel template 3 via an automatic telescopic rod matrix 2. The automatic telescopic rod matrix 2 consists of 4 rows and 6 columns, forming a top extension system. The automatic telescopic rod 2 is an HSG80 / 45-1800 type double-acting hydraulic cylinder. The steel template 3 has evenly distributed reinforcing ribs 32 vertically welded to the back of the steel main panel 31. The spacing between the reinforcing ribs 32 is 0.8 to 1.2 m, and in this embodiment, it is 1 m. The reinforcing ribs 32 are H-beams with a width and height of 200 mm. The steel main panel 31 has a thickness of 0.05 m, a width of 3 m, and a length of 5 m. The steel main panel 31 is made of Q235B steel plate.

[0024] The top of the dump truck 4 is equipped with an operating platform 5 made of steel pipes and wooden planks, and a ladder 6 connected to the operating platform 5 is installed on one side to facilitate the operator's movement up and down.

[0025] The working principle of this utility model is as follows:

[0026] In the pretreatment stage, the section requiring reinforcement is first measured to determine the reinforcement range, and a concrete base is poured. When the trolley moves to the working face, the hydraulic jacking system is activated, causing the steel formwork 3 to be pushed open onto the concrete base by the hydraulic cylinder. Simultaneously, both sides of the steel formwork 3 are sealed, and measurements are taken to calibrate the formwork. Figure 3 During concrete pouring, the concrete delivery pipe of the concrete pumping system delivers concrete to the work area through the operating platform 5 on top of the dump truck 4. Concrete is poured in layers, with a thickness not exceeding 400mm, and is simultaneously compacted using an immersion vibrator. Throughout the construction process, the hydraulic jacking system, in conjunction with the steel formwork 3, provides stable support, effectively resisting construction vibrations and ensuring operational safety and construction quality. After pouring is completed and the concrete reaches a certain strength, the hydraulic jacking system retracts, causing the steel formwork 3 to detach from the concrete structure, allowing the trolley to move to the next work area to continue working.
