Description

Technical Field

[0001] This utility model belongs to the field of concrete pouring technology, specifically relating to a diversion pipe monitoring system for the secondary lining concrete pouring of a tunnel arch. Background Technology

[0002] During the pouring of secondary lining concrete for the arch of highway and railway tunnels, the enclosed nature of the arch makes it difficult to ensure a tight fit between the concrete and the initial support, leading to voids in the arch. Currently, the common practice is to install multiple sensors on the initial support of the arch. While these sensors can monitor the pouring height, they are not removable or reusable, resulting in high costs. Furthermore, the data from multiple sensors requires subsequent analysis and processing, making the data processing cumbersome. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a low-cost, on-site direct observation and back-end monitoring system that can achieve timely control and accurate data recording during the construction process, making the arch pouring process controllable and the data verifiable afterward.

[0004] This utility model discloses a diversion pipe monitoring system for the secondary lining concrete pouring of a tunnel arch, comprising a diversion pipe, fasteners, a receiving box, a support platform, a gravity sensor, an audible and visual alarm, a background monitoring system, and a network camera. The system is characterized by: fasteners fixedly installed on the diversion pipe; the diversion pipe being inserted into the upper part of the receiving box; the receiving box being mounted on the support platform; a gravity sensor being installed at the bottom of the receiving box; the gravity sensor being connected to the audible and visual alarm via a connecting wire; and a network camera being installed on the side of the receiving box, wirelessly connected to the background monitoring system.

[0005] The upper end of the guide pipe is a 90-degree bend.

[0006] The receiving box is a transparent square shape.

[0007] Compared with existing technologies, this invention has significant advantages. As can be seen from the above technical solution: fasteners are fixedly installed on the guide pipe, which is inserted into the upper part of the receiving box. The receiving box is installed on a support platform, and a gravity sensor is installed at the bottom of the receiving box. The gravity sensor is connected to an audible and visual alarm via a connecting cable and wirelessly connected to a background monitoring system. A network camera is installed on the side of the receiving box, wirelessly connected to the background monitoring system. A guide pipe is installed at the highest point of the initial support of the arch. When concrete is poured to the upper end of the pipe, the cement slurry on the surface flows into the pipe through the upper end and into the receiving box below, indicating that the concrete has been poured to the arch. The network camera monitors the receiving box and transmits the monitored data to the background monitoring system, which records the slurry flow into the receiving box. This device realizes real-time on-site observation and background monitoring, ensuring timely control of the construction process and accurate data recording, thus making the arch pouring process controllable and allowing for data retrieval afterward. In summary, this utility model is characterized by low cost, and can realize on-site direct observation and remote monitoring functions, ensuring real-time control of the construction process and accurately recording relevant data, thereby enabling effective management of the arch pouring process and allowing for data verification afterward.

[0012] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific embodiments, structure, features, and effects of this utility model.

[0013] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:

[0014] This utility model is a system for monitoring the concrete pouring of the secondary lining of a tunnel arch using a diversion pipe. It includes a diversion pipe 1, fasteners 2, a receiving box 3, a support platform 4, a gravity sensor 5, an audible and visual alarm 7, a background monitoring system 8, and a network camera 9. The system is characterized by: fasteners 2 fixedly installed on the diversion pipe 1; the diversion pipe 1 is inserted into the upper part of the receiving box 3; the receiving box 3 is installed on the support platform 4; a gravity sensor 5 is installed at the bottom of the receiving box 3; the gravity sensor 5 is connected to the audible and visual alarm 7 via a connecting cable 6 and wirelessly connected to the background monitoring system 8 via a network; a network camera 9 is installed on the side of the receiving box 3 and wirelessly connected to the background monitoring system 8; the upper end of the diversion pipe 1 is a 90-degree bend; and the receiving box 3 is a transparent square.

[0015] When using; see; Figure 2 The support platform 4, connecting line 6, audible and visual alarm 7, and network camera 9 are installed on the secondary lining trolley rod 13. Before the concrete is poured into the secondary lining template 12 at the arch top, a hole is drilled in the template 12, and a guide pipe 1 is inserted through the hole. The top of the guide pipe 1 is against the highest point 10 of the initial support of the arch top. After the guide pipe 1 is inserted into the template 12, the hole is blocked with plastic material. Fasteners 2 are used to fix the guide pipe 1 to the template 12 to prevent it from moving down. Then the concrete is poured into the secondary lining 11. When the concrete is poured to the upper end of the guide pipe 1, the cement slurry on the surface flows into the guide pipe 1 through the upper end of the guide pipe 1 and into the slurry collection box 3 below. This indicates that the concrete has been poured to the highest point 10 of the initial support of the arch top. At the same time, the network camera 7 monitors the collection box 3 and transmits the monitored data to the background monitoring system 8. The background monitoring system 8 records the slurry flow into the collection box 3.

[0016] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
