Intelligent tunnel lining trolley

Abstract

Provided is an intelligent tunnel lining trolley, characterized by comprising a door-shaped main steel frame, a concrete pouring informationized monitoring system, an end template, a template cleaningand surface lubricating system, an automatic running gear, and a layered window-by-window pouring and cleaning system. The tunnel lining trolley is simple in structure and reasonable in design, and real-time monitoring of each parameter in a concrete pouring process is realized, automation degree of equipment is improved, cleaning and template surface lubrication operation flow are simplified. The intelligent tunnel lining trolley provides convenience for on-site management and construction, and has certain environmental protection property and very high security.

Description

technical field [0001] The invention relates to the technical field of lining trolley equipment, in particular to an intelligent tunnel lining trolley. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. Due to the particularity of its location and construction structure, the construction process is relatively difficult and complicated, and the requirements for construction safety and efficiency are relatively high. During the concrete pouring process of the tunnel vault, whether the pouring is completed is usually determined by setting a diversion pipe. After the concrete is filled, it will overflow from the diversion pipe on the other side, indicating that the work is completed. However, if the concrete encounters low-temperature weather, the solidification time will be shortened, and the solidified solid will not easily overflow from the draft tube. A...

AI Technical Summary

Problems solved by technology

However, if the concrete encounters low-temperature weather, the solidification time will be shortened, and it will not easily overflow from the diversion pipe after solidification. At this time, cavities will easily occur, and overweight concrete will cause construction accidents such as formwork collapse.

[0003] When the lining trolley advances to the next working position, if the trolley is lifted before reaching the designated position, the formwork will collide with the second lining, thereby damaging the second lining. However, the existing trolley does not take measures to prevent such accidents. effective measures

[0004] The end formwork of the existing lining trolley is composed of multiple formworks separated from the trolley. Manual installation and splicing are required before concrete injection, which is time-consuming and laborious. Wooden formwork is generally used, which is easy to cause damage during repeated assembly and disassembly. Damage or deformation is not conducive to improving pouring efficiency. In addition, due to errors during operation, steps are often formed at the junction of the two sections and the second lining, which affects the pouring effect

[0005] In the process of cleaning the formwork and spraying the release agent on the existing lining trolley, it is often used to manually spray clean water and clean, and then manually spray the release agent, which not only causes a lot of waste of clean water and release agent, but also increases labor costs , The sewage and other dirt left on the job site will also cause environmental pollution, and it is not conducive to site management and construction, and has a great impact on pouring engineering operations, which is not conducive to the realization of equipment automation and is not conducive to improving work efficiency

[0006] The running wheel mechanism of the existing trolley is rigidly connected to the trolley individually or in groups. Due to the large size of the trolley, it is difficult to ensure that the guide rails are completely flush over a long distance, which causes the trolley to wrap around when pouring. The geometric center point will produce a certain pitch and deflection, which will affect the flatness of concrete pouring and produce joints

[0007] Most of the existing tunnel lining trolleys pour concrete directly from the observation window of the formwork, which requires manual pipe replacement and cleaning. The degree of automation is not high, the efficiency is low, and the concrete is poured from top to bottom. Using this pouring method, segregation is easy to occur , the compactness of the concrete after pouring is not high, if the vibrating effect is not good, there will be air bubbles, pitting and other phenomena, resulting in unsatisfactory pouring effect
