Problems solved by technology

The main problems: 1. It is easy to cause the second lining concrete of the tunnel vault to be voided due to various reasons
2. It is easy to cause the end of the second lining of the upper plate of the tunnel trolley to crack
3. It is easy to cause uneven strength of tunnel lining vault concrete, honeycomb pockmarked surface, lack of compactness, cold seam, etc. due to insufficient vibration

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] see Figure 2 to Figure 8, the tunnel secondary lining concrete pouring control system, wherein the tunnel secondary lining concrete pouring system includes a three-dimensional laser scanner, a flow sensor 1, a temperature sensor 5, a pressure visualization soft lap device, a high-frequency pneumatic vibrator 11, an automatic plug-in vibrator device, pressure sensing sheet 16 and gas compressor 13. The flow sensor 1 is installed on the concrete main delivery pump pipe 2, the temperature sensor 5 is installed on the back of the steel formwork 3 of the second lining trolley of the tunnel, and the pressure visualization soft-lapping device includes a rubber plate 6. The rubber plate 6 mentioned above is installed on the bottom of the second lining trolley close to the upper plate and the second lining overlapping plate 7, and the...

Abstract

The invention discloses a tunnel secondary lining concrete pouring control system and method. The system comprises a trolley soft lap joint control module, a communication module, a PLC control analysis module, an alarm module, a pneumatic vibration control module, a plug-in vibration control module, a temperature module and a pressure module. The method comprises the following steps: S1, the pneumatic vibration control module and the PLC control analysis module control pneumatic vibration; S2, the plug-in vibration control module and the PLC control analysis module control plug-in vibration;and S3, the PLC control analysis module compares the estimated concrete pouring square value with the concrete flow data, when the concrete flow data is larger than the estimated concrete pouring square value, the PLC control analysis module sends an instruction to the alarm module, the alarm module sends an alarm signal, and concrete pouring is stopped. Automatic vibration in a tunnel secondary lining vault is achieved, and the phenomena of void separation, nonuniformity, honeycomb pitted surface and incompactness caused by local concrete blocking of the secondary lining vault are prevented.

Description

technical field [0001] The invention relates to a control system, more specifically to a control system and a control method for concrete pouring of the second lining of a tunnel, and 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 steel formwork of the second lining trolley is directly overlapped with the concrete of the upper slab before concrete pouring, and there is no relevant top pressure control, so it is easy to crack the lapped concrete and cause the construction joints to fall off; during the pouring process, The ground pump pumps the concrete to each feed port of the second lining tr...
