Example Embodiment

[0037] Example 1

[0038] As shown in the figure, a device for determining the amount of lining in tunnel construction includes a template 9, which is provided with a grouting outlet 15 and a grouting inlet 19, the grouting outlet 15 is arranged outside the template 9, and the grouting inlet is 19 is arranged on the inner side of the template 9; a reinforcing rib 22 is installed on the top of the inner side of the template 9, and a plurality of sets of transverse telescopic support rods 17 and longitudinal telescopic support rods 18 are installed under the reinforcing ribs 22.

[0039] Each set of transverse telescopic support rods 17 and longitudinal telescopic support rods 18 is composed of two transverse telescopic support rods 17 and two longitudinal telescopic support rods 18 intersecting. Jack or hydraulic cylinder.

[0040] The reflective targets 7 in the template and the reflective targets 11 outside the template are evenly installed on the inner and outer walls of th...

Abstract

The invention provides a tunnel construction lining quantity determining device, which is characterized by comprising a formwork, wherein a grouting outlet and a grouting inlet are formed in the formwork; the grouting outlet is formed in the outer side of the formwork; the grouting inlet is formed in the inner side of the formwork; the top of the inner side of the formwork is provided with reinforcing bars; and a plurality of groups of transverse telescopic support rods and longitudinal telescopic support rods which are in crossed arrangement are arranged under the reinforcing bars. Compared with the prior art, the tunnel construction lining quantity determining device has the advantages that a three-dimensional laser scanning technology is used for scanning reflecting targets arranged in a tunnel to determine the volume of a tunnel; through testing distribution points at different layers, the lining volume is determined through subtraction by a computer; the concrete injection quantity is calculated; the whole process is determined through the calculation by the computer; the data is precise; the speed is high; the waste in the construction process is avoided; and meanwhile, the construction period is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a device for determining the amount of lining in tunnel construction and a construction method thereof. Background technique [0002] Lining refers to a permanent support structure built with reinforced concrete and other materials along the periphery of the tunnel body in order to prevent the deformation or collapse of the surrounding rock. Lining technology is usually used in tunnel engineering and water conservancy channels. The lining is simply the inner lining, and the common one is to use block lining, which can be prestressed high-pressure grouting plain concrete lining. [0003] Relatively speaking, the secondary lining and the initial support refer to the inner lining built with concrete and other materials under the condition of the initial support of the tunnel, so as to achieve reinforcement support, optimize the route waterproof and drai...
