Usually, there are quality problems such as loose concrete vibration, cold joints, aggregate concentration, and vault lining cavities. The later concrete defect treatment results in more complex processes and higher construction costs, which has a certain impact on the construction period and process conversion. There are many quality defects and uncertainties in the tunnel lining operation, which cannot meet the construction quality standards to the greatest extent. Summary of the invention

[0038] Hereinafter, the technology in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0039] Reference Figures 1 to 5 The present embodiment provides an intelligent traveling concrete lining trolley, which includes a vehicle body 1 and a template assembly 2. The template assembly is divided into a left template 201, a right template 202, a left top template 203 and a right top template 204, which are sequentially connected to form a closed structure. Four grouting holes 205 and thirty-two pouring windows 206 are provided on the template assembly 2. The grouting holes 205 are located at the top of the template assembly 2 for injecting concrete. The template assembly 2 is divided into eight layers from top to bottom, and each layer is evenly distributed with four pouring windows 206. The four pouring windows 206 of each layer are staggered with the pouring windows 206 of the adjacent layer in the vertical direction to form a staggered arrangement to ensure uniform layered pouring of concrete.

[0040] The turntable mounting seat 3 is fixed on the steel structure frame of the vehicle body 1, and a plurality of distribution pipes 301 are evenly distributed along the circumference of the turntable mounting seat 3. Each distribution pipe 301 is fixed on the turntable mounting seat 3 through a steel support 302, and the outer side of the distribution pipe 301 extends to the grouting hole 205 and the casting window 206 through a grouting pipe 303. The inner side of the distribution pipe 301 is provided with a rotating material distribution device, which includes a feed pipe 304, which is provided on the turntable mounting seat 3 and can rotate around the axis of the turntable mounting seat 3. The feed pipe 304 includes a butt pipe 305 extending radially along the turntable mounting seat 3, and a pumping pipeline 306 is connected below the feed pipe 304 to transport concrete to the distribution pipe 301. A flexible tube is provided in the middle of the butt joint pipe 305. Both ends of the butt joint pipe 305 are driven by a hydraulic telescopic cylinder 307. Both ends of the hydraulic telescopic cylinder 307 are respectively connected to both ends of the butt joint pipe 305 to drive the butt joint pipe 305 to telescope along its axial direction. The rotation drive device 310 is provided on the turntable mounting seat 3 to drive the butt joint pipe 305 to rotate around the axis of the turntable mounting seat 3.

[0041] A rubber overflow bell mouth 308 is provided inside the material distribution pipe 301 , and an overflow hole is provided at the bottom of the turntable mounting seat 3 , which is connected to a leakage slurry collection and diversion branch pipe 309 .

[0042] In this embodiment, the control accuracy of the rotary material distribution device and the degree of automation of the construction process are further improved.

[0043] A high-frequency pneumatic vibrator is installed on the formwork assembly 2, and the vibrator includes an insertion vibrator 401 and an attachment vibrator 402. Four insertion vibrators 401 are respectively arranged on the left and right sides of the grouting hole 205, which are directly inserted into the concrete for vibration. Attachment vibrators 402 are alternately arranged between the pouring windows 206 of each layer, which are attached to the formwork to vibrate the concrete to ensure the density of the concrete.

[0044] Since the pouring windows 206 are staggered and the vibrators are spaced between the pouring windows 206, this layout ensures that on each section of the trolley, the pouring windows 206 and the vibrators are also staggered, which can more effectively cover the concrete pouring area of ​​each layer, ensuring that the concrete can be vibrated evenly during vibration, further improving the density of the concrete and the construction quality.

[0045] The vibrator is controlled by the pneumatic vibration main control system 403. The main control system provides a stable air source through the air storage tank 404 and the air compressor 405. The pneumatic vibration main control system 403 can automatically adjust the vibration frequency and time according to the pouring status of the concrete by the PLC control program to ensure the best vibration effect. The pneumatic vibration main control system 403 monitors the pouring status of the concrete in real time through the sensor installed at the bottom of the trolley, and feeds the data back to the PLC control system. The PLC system dynamically adjusts the vibration parameters of the vibrator according to the real-time data to ensure that the concrete in different parts can be properly vibrated to ensure the density and strength of the concrete.

[0046] The template assembly 2 is provided with a visual plug structure 5 for closing the opening of the template. The visual plug structure 5 includes an upper plug 501 and a lower plug 502. The upper plug 501 adopts a polymer standard block and has transparent or translucent properties, allowing construction personnel to monitor the concrete pouring process in real time. The lower plug 502 adopts a steel mold structure and is tightly connected to the template assembly 2 of the trolley through a flange 505 to provide sufficient support to prevent the plug from loosening or displacement during construction. A waterstop 503 is provided between the upper plug 501 and the lower plug 502 to ensure the sealing during the concrete pouring process and prevent the occurrence of leakage. A polymer adjustment block 504 is provided above the upper plug 501, which is used to adjust the position and size of the plug according to construction requirements to ensure that the plug fits tightly to the template.
