Abstract

The application relates to a bearing capacity detection device for a support structure of a jet fan in a highway tunnel, which includes a reaction force component for connecting with a pre-embedded steel plate of the jet fan, and a pressure component for abutting against the top wall of the tunnel is arranged on the reaction force component. The reaction force component includes a beam and a connecting piece for fixing on the embedded steel plate. The connecting piece is provided with a support rod. The two ends of the beam are symmetrically provided with threading seats. The support rod connection on the group of embedded steel plates. The reaction force component of the present application is connected with two groups of embedded steel plates at the same time, and the bearing capacity of the two groups of embedded steel plates can be tested at the same time through the pressurization of the pressurizing component, the detection efficiency is high, and the construction period is short.

Description

technical field [0001] The present application relates to the field of tunnel detection technology, and in particular, to a bearing capacity detection device and detection method for a support structure of a jet fan in a highway tunnel. Background technique [0002] With the development of transportation technology, there are more and more long tunnels, and tunnel ventilation has become an important factor affecting driving comfort. At present, most tunnel ventilation adopts jet fan, which is suspended on the top of the tunnel. Article 11.2.4 of "Detailed Design Rules for Highway Tunnel Ventilation" JTGTD702-02-2014 stipulates that the structural bearing capacity of the supporting fan should not be less than 15% of the actual static load of the fan. times, the load test of the supporting structure should be done before the fan is installed. [0003] The Chinese Patent Publication No. CN107121247A discloses a unilateral tunnel fan supporting structure bearing capacity detect...
