Problems solved by technology

[0003] However, during the construction, due to the low quality awareness of the construction personnel and the multi-section structure of the steel arch, it is difficult to control the spacing and verticality of the initial support steel arch when it is reassembled into an arch inside the tunnel , and during the installation process, operations such as manual lifting of the roof are used to stabilize and fix the steel arch frame. The construction operation is extremely inconvenient and the safety cannot be guaranteed. Therefore, the spacing and verticality of the steel arch frame must be strengthened during the installation process of the construction site. control

Abstract

The invention relates to an electromagnetic type verticality controller. Thus, whole verticality of installation of primary support steel arch supports. The controller comprises a main shaft which can be adjusted in a telescoping manner, two electromagnetic suction discs arranged on two ends of the main shaft, a wire connecting the main shaft and the electromagnetic suction discs, a power supply and a control switch. The power supply and the control switch are installed on the main shaft and serially connected with the electromagnetic suction discs. Multiple verticality controllers are properly arranged among steel arch supports, and the main shaft is adjusted to be in the designed length, so whole separation distance and verticality during initial installation of the steel arch supports can be effectively ensured. Via the electromagnetic suction discs, electromagnetic fixing force can be quickly formed, so the verticality controller can be firmly hinged to I-shaped steel ribbed plates of the steel arch supports and it can be achieved that the verticality controller and the steel arch supports can form a whole structure quickly. After the steel arch supports are installed, demagnetization can be quickly carried out and the steel arch supports can be dismantled. By controlling the whole separation distance and verticality during initial installation of the steel arch supports, precision of post initial installation of other parts can be ensured and installation technology and quality control during the construction process are greatly improved.

Description

technical field [0001] The invention relates to the field of tunnel construction in construction engineering, and in particular relates to an electromagnetic verticality controller for ensuring the overall verticality of the installation of the initial steel arch frame of the tunnel. Background technique [0002] With the further improvement of tunnel construction quality requirements, the installation quality of the initial support steel arch is particularly important to the overall quality of the tunnel. Play a supporting role in the stressed structure. [0003] However, during the construction, due to the low quality awareness of the construction personnel and the multi-section structure of the steel arch, it is difficult to control the spacing and verticality of the initial support steel arch when it is reassembled into an arch inside the tunnel , and during the installation process, operations such as manual lifting of the roof are used to stabilize and fix the steel a...
