Problems solved by technology

However, due to the dense reinforcement of the second-lined vault, the vault concrete cannot be manually vibrated, so there are problems such as the inability to ensure that the vault concrete is compact and the distribution of the second-lined vault concrete is uneven, and there are huge risks in quality and safety. As a result, the concrete strength of the tunnel lining vault is uneven, the concrete is not dense and the cavity is empty, so the traditional tunnel lining technology can no longer meet the construction needs

Abstract

The invention discloses a concrete vibration system for tunnel secondary lining. The concrete vibration system comprises a plurality of automatic inserting vibration devices (1), a plurality of high-frequency pneumatic vibrators (2), a gas compressor (3) and an electric cabinet. The automatic inserting vibration devices (1) are arranged on the back surfaces of tunnel secondary trolley steel molding plates (4). The high-frequency pneumatic vibrators (2) are arranged on the back surfaces of the tunnel secondary trolley steel molding plates (4). The automatic inserting vibration devices (1) are connected with the gas compressor (3). The high-frequency pneumatic vibrators (2) are connected with the gas compressor (3). The gas compressor (3) is connected with the electric cabinet. Automatic inserting type vibration of the tunnel lining concrete is achieved, and the problems that vibration of deep and heavy concrete is insufficient and concrete is not dense are solved.

Description

technical field [0001] The invention relates to a concrete vibrating device, in particular to a tunnel secondary lining concrete vibrating system, which belongs to the technical field of tunnel lining construction. Background technique [0002] At present, with the rapid development of high-speed rail in my country, there are more and more tunnels; with the continuous improvement of tunnel lining quality and standardized construction requirements, the quality requirements of tunnel lining concrete are getting higher and higher. [0003] In the traditional tunnel lining process, the tunnel second lining trolley is positioned and then the delivery pump pipe is reinforced and installed. The ready-mixed concrete is sent to each sub-window of the second lining trolley through the concrete ground pump, and each sub-window is poured. When pouring, use a hand-held vibrator to vibrate, and when pouring a vault, use an electric flat-plate attached vibrator to vibrate. However, due to...
