Abstract

The invention relates to the field of immersed tube tunnels, and discloses an immersed tube tunnel construction monitoring system. The immersed tube tunnel construction monitoring system is characterized in that adjacent tube sections of an immersed tube tunnel are provided with first test sensors used for testing the opening-closing degree between the test tube sections, a second test sensor used for monitoring relative displacement changes between the tube sections in the horizontal direction and third test sensors used for monitoring differential displacement between the tube sections in the vertical direction; the adjacent sections are provided with fourth test sensors therebetween used for measuring the opening-closing degree of a gap between the sections; an end sealing door is provided with stress sensors used for testing the maximum bearing stress and fifth test sensors used for testing maximum deformation conditions; and the adjacent tube sections are provided with sixth test sensors used for monitoring settlement changes of the tube sections, seventh test sensors used for monitoring displacement changes of the tube sections and temperature sensors used for monitoring temperature changes in the immersed tube. The invention further provides a construction technology. The immersed tube tunnel construction monitoring system and the construction technology thereof are comprehensive in monitoring, and capable of ensuring monitoring data to be reliable, timely and effective.

Description

technical field [0001] The invention relates to the field of construction monitoring of immersed tube tunnels, in particular to a construction monitoring system and construction technology of immersed tube tunnels. Background technique [0002] Immersed tube tunnels started relatively late in my country, and there is not much experience in immersed tube tunnel projects. Generally, immersed tube tunnels that have been completed or are under construction are relatively small in length and scale. The standard pipe section of the immersed tube tunnel of the Hong Kong-Zhuhai-Macao Bridge is 180.0m long and weighs 70,000 tons. The Hong Kong-Zhuhai-Macao Bridge is composed of 33 similar immersed tubes. It is the largest immersed tube tunnel under construction in China and even in the world. [0003] Such immersed tube tunnels face many technical difficulties and many risk sources during construction, but my country does not have sufficient construction engineering experience for i...
