Abstract

The invention discloses an immersed tunnel pipe joint thrust device. The immersed tunnel pipe joint thrust device comprises an upper fixed block, a support table, an engagement boss and a lower fixed block; a fixed hole is formed in the upper fixed block; a cross beam is fixed on the inner side of a stand column; a connecting block is arranged in middle of the cross beam; a short bracket is mounted on the left side above the lower fixed block; long brackets are fixed on two sides of the middle of the lower fixed block; and an engagement groove is formed in the right side of the engagement boss. The immersed tunnel pipe joint thrust device is provided with engagement teeth for engaging tunnel bodies, so that the friction area can be increased during vibrating, and the accident probability is reduced; a fixed bolt is arranged in the fixed hole for effectively fixing two sides of the upper fixed block without releasing; and included angles between the inclined surfaces of the upper fixed block and the lower fixed block and the horizontal line are 20 degrees, so that the resistance suffered from the upper fixed block and the lower fixed block can be reduced, the wear is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of immersed tube tunnels, in particular to a thrust device for pipe joints of immersed tube tunnels. Background technique [0002] Waterproofing and shockproofing in subsea tunnels are one of the key issues in tunnel design and construction. Usually, during construction, the waterproofing at the joints of pipe joints is very firm, but slight vibrations will occur when large vehicles pass inside. It cannot be absorbed, and it can only make the whole tunnel vibrate accordingly. After a long time, it is easy to cause accidents. When there is a large impact such as an earthquake on the seabed, the independent shaking of each pipe joint is likely to cause the junction gap to crack, resulting in a safety accident. Contents of the invention [0003] The purpose of the present invention is to provide a thrust device for pipe joints of immersed tunnels, so as to solve the problems such as insufficient seismic capac...
