System for Quantitative Calculation of Concrete Filling Voids During Tunnel Secondary Lining Construction

Abstract

The invention discloses a system for quantitatively calculating concrete pouring voids during the secondary lining construction period of tunnels. The system includes: a plurality of detection units, each detection unit detects the height of the concrete pouring surface, and generates a pouring height representing the concrete The electrical signal; the judgment unit, which receives multiple electrical signal data, and processes each electrical signal data to obtain the height data of the monitoring points distributed according to a certain density on the concrete pouring surface during the secondary lining construction period, and according to these heights data to calculate the volume of unfilled voids above the concrete surface and below the flashing. The invention effectively solves the problem of unclear pouring state of the concrete during the secondary lining construction period, can provide reliable judgment basis for construction personnel, guarantee the quality of lining construction, and reduce or avoid the formation of cavities from the source.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and relates to a system for quantitatively calculating the concrete pouring cavity during the secondary lining construction period of the tunnel. Background technique [0002] Holes in the tunnel lining will not only cause the vault to fall off, threatening driving safety, but also reduce the bearing capacity of the tunnel structure and reduce the engineering safety factor. Since the lining concrete was poured in the formwork trolley during the secondary lining construction, the construction personnel could not accurately judge the pouring state of the vault concrete, which resulted in the insufficiency of the lining concrete pouring during the secondary lining construction and could not be dealt with in time. However, the existing detection and monitoring technology cannot effectively identify the pouring state of the lining concrete during this construction period, so the insufficie...
