Lining circular ring assembled by prefabricated segments with corbel connecting bases and assembling method of lining circular ring

Abstract

The invention discloses a lining circular ring assembled by prefabricated segments with corbel connecting bases and an assembling method of the lining circular ring. The lining circular ring is provided with symmetrical double-sided wedge-shaped rings. The capping block assembling point is located at the 0-degree position of the lining circular ring, the ring width of the outer diameter of the circular ring at the point is the minimum value or the maximum value, the point, opposite to the capping block, of the 180-degree point is a first standard block, and the points, adjacent to the two sides of the first standard block, of the capping block are second standard blocks. The inner arc surface of the second standard block and the inner arc surface of the adjacent block are each provided with a corbel connecting base which is integrally formed and protrudes out of the inner arc surfaces, each corbel connecting base is composed of a connecting base face in the horizontal plane direction and a connecting base face in the vertical plane direction, the four corbel connecting bases are symmetrically distributed in the lining circular ring, and the formed lining circular ring is in a mode1 or a mode 4. The top sealing block and the adjacent blocks on the two sides are spliced into a whole to rotate by 180 degrees around the Y axis to be in place, and the first standard block and the standard blocks sequentially spliced with the first standard block are spliced into a whole to rotate by 180 degrees around the Z axis to be in place in a mirroring mode to form a lining circular ringin a mode 2 or a mode 3. The universality of the segment is improved, and drilling and steel bar planting on the inner arc surface of the segment are avoided.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a lining ring with a corbel connection base and a prefabricated segment assembly and an assembling method thereof, which are used for assembling the lining segment inside a traffic tunnel built by the shield method. Background technique [0002] The internal space of the traffic tunnel built by the shield method is usually divided into three layers from top to bottom according to the functional area: the key smoke exhaust layer, the motor vehicle driveway layer, the evacuation rescue and pipeline corridor layer, see figure 1 shown. Components such as flue slabs and driveway slabs are transmitted to the main structure through the corbel supports at both ends. The corbel support protrudes from the inner arc surface of the segment and is integrated with the segment structure. [0003] In the prior art, the construction method of planting reinforcement ...

AI Technical Summary

Problems solved by technology

[0004] (1) Drilling damages the segment structure, especially for the assembled lining structure, the damage is difficult to repair

[0005] (2) It is difficult to locate the drilling hole and the waste hole rate is high

[0007] (4) Construction operations such as drilling and planting bars, cast-in-place corbels, etc. have high intensity, low work efficiency, and poor environment. They are operated in parallel with shield tunneling, and there are many cross-interferences

Therefore, the pre-embedded, reserved, prefabricated and other structures adopted for a specific pipe block will lose the target position under the condition of dynamic adjustment of the spatial position of each pipe block, so that it is difficult to guarantee its effectiveness
