Embodiment 1

[0032] see Figure 1-7 as shown,

[0033] The support equipment used for tunnel construction includes: support members 10, processing components 30, used to connect the support members 10 to form an arch support structure, and the adjacent surfaces of the formed arch support structure are connected through a bonding substrate 40, and the bonding support The plate assembly 20 is plugged on the processing assembly 30 and is in contact with the construction surface, wherein the processing assembly 30 includes a base 31 of a cubic box structure, and a first hole is provided in the center of the base 31 to be plugged and fitted with the lamination spreader assembly 20 . Assembling the through hole 32, the two corresponding sides of the base body 31 are clamped with a half sleeve body 50. The half sleeve body 50 has a fitting side corresponding to the side of the base body 31, and the upper and lower ends of the fitting side are connected with the upper and lower end surfaces of the...

Embodiment 2

[0044] In the actual use of the supporting equipment for tunnel construction of the present invention:

[0045] Bending the I-shaped profile as a half-arched beam supported by the tunnel and connecting the two half-arched beams through the processing component 30 to form an arched beam structure, and then connecting the linear I-shaped beam through the processing component 30 The profiles are connected to form the side beam structure, and finally an arched support structure is formed, and then the connection between two adjacent arched support structures is realized by laminating the base plate 40, which can be quickly installed in the tunnel during the excavation process of the tunnel. Tunnel support equipment, and when the deformation of the tunnel rock formation leads to expansion and displacement increases, it will give the tunnel rock formation counterforce in real time during the support process to improve the stability of the rock formation.

Embodiment 3

[0047] In this embodiment, the tunnel excavation simulation is carried out by artificially piling up the mountain, and the support equipment for tunnel construction of the present invention with different support angles is respectively erected at both ends of the tunnel. 7 times of excavation, and measured the settlement of the vault after each excavation, the results are as follows Figure 8 As shown, it can be seen that when the erection support angle of the present invention is selected to be 120°, the vault settlement is lower than 90° of erection equipment, and the two erection support angle equipment can effectively ensure the manual simulation of the tunnel after 7 times of simulated excavation in the tunnel. Stability of the rock formation with no occurrence of collapse or dislodgement of rock fragments.

[0048] At the same time, in this embodiment, the stress analysis of the laminated spreader assembly 20 and the base body 30 under compression, the results are as fol...

Abstract

The invention discloses supporting equipment for tunnel construction, and belongs to the technical field of tunnel construction. The device provided by the invention comprises a supporting component,a processing assembly and a bonding supporting plate assembly, wherein the processing assembly is used for connecting the supporting component to form an arch-shaped supporting structure, and adjacentsurfaces of the formed arch-shaped supporting structure are connected through a bonding substrate; the bonding supporting plate assembly is spliced on the processing assembly and in contact with a construction surface; the processing assembly comprises a base body of a cubic box body structure, a first assembly through hole in splicing fit with the bonding supporting plate assembly is formed in the center of the base body, and the two corresponding sides of the base body are clamped with semi-splicing sleeve bodies; the supporting equipment realizes that the supporting equipment can support the supporting surface effectively and adjust the splicing degree with the supporting surface freely, the stress of a tunnel supporting structure is improved, the problem that the supporting has a hanging point is solved, and the safety of the tunnel construction is ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, and more particularly, to a support device for tunnel construction. Background technique [0002] At present, in the construction of tunnels, due to its particularity, it is necessary to support the tunnels under construction to ensure the safety during the construction process and ensure that there is nothing wrong with it. Generally, in the process of tunnel construction, it is supported by side construction and piling, and then laying support pipes. There are certain difficulties, resulting in the difficulty of tunnel construction. Contents of the invention [0003] The purpose of the present invention is to provide a support device for tunnel construction, which can effectively support the support surface and can self-adjust the fit of the support surface, improve the force of the tunnel support structure, and solve the problem of suspended points in the support. to ensure the...
