Embodiment Construction

[0017] Please also refer to figure 1 , figure 2 and image 3 , the enclosure structure of the present invention is different from the traditional enclosure structure. The traditional enclosure structure usually uses steel bars or steel plates as reinforcements, while the reinforcement structure of the present invention is composed of upper and lower reinforcement cages and middle FRP reinforcement cages 2; The position of the FRP cage 2 corresponds to the position where the shield machine 7 enters and exits the shaft of the cable tunnel, and the height of the FRP cage 2 is greater than the height of the shield machine 7, so that the shield machine 7 can pass through the FRP cage 2 ; The upper reinforcement cage 1, the middle FRP reinforcement cage 2, and the lower reinforcement cage 3 are connected to form a complete reinforcement structure. Among them, the FRP reinforcement cage 2 can be a GFRP reinforcement cage or a CFRP reinforcement cage; the upper reinforcement cage 1...

Abstract

The invention discloses a cable tunnel shaft enclosure structure, which is provided with a reinforcement structure formed by connecting an upper reinforcement cage, a middle FRP reinforcement cage and a lower reinforcement cage. At the same time, the invention discloses a shield machine cutting construction method for the cable tunnel shaft enclosure structure. The construction method comprises the following steps: lifting, lapping and binding the upper reinforcement cage, the middle FRP reinforcement cage and the lower reinforcement cage; casting concrete to form the cable tunnel shaft enclosure structure; and cutting the cable tunnel shaft enclosure structure when a shield machine advances to the FRP reinforcement cage and a cutter head of the shield machine is replaced by a hob, a toothed cutter or a scraper. By means of the enclosure structure and the construction method, the construction progress of a cable tunnel is sped up, and the abrasion on cutters of the shield machine is reduced to a certain extent, so the enclosure structure and the construction method are suitable to be popularized in enclosure structures at the inlet and the outlet of a cable tunnel shaft for the shield machine.

Description

technical field [0001] The invention relates to an enclosure structure, in particular to an enclosure expansion structure for a shaft of a cable tunnel. [0002] The invention also relates to a shield machine cutting construction method of the shaft enclosure structure of the cable tunnel. Background technique [0003] With the continuous development and progress of urbanization in our country, the underground development of electric power, communication and other cables has become an inevitable trend. The construction of underground cable tunnels has replaced large high-voltage iron towers and corresponding overhead lines, freeing up more ground space for the urbanization process. . The vertical shaft of the cable tunnel usually adopts steel bars or steel plates as the enclosure structure of the reinforcement to achieve the purpose of water-stopping, anti-seepage, and load-bearing. The shield method must be selected for cable tunnel construction. However, in shield tunnel...
