Embodiment Construction

[0032] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as Figure 9 As shown, it is a construction structure of a road tunnel in the tidal surge area proposed by the present invention, which includes two tidal dams and the tunnel body. The two tidal flat dams are filled with dregs, and their forms can adopt various existing tidal flat dams, and can be designed in advance by entrusting the water conservancy department with the experience of tidal reclamation and land reclamation of the water conservancy department. Tidal dams are arranged in parallel on both sides of the tunnel body to block tide surges. In addition, the applicant found through research that when building a tunnel in the tidal flat area, there is no upward thrust generated by seawater seeping upwards, so there is no need to set uplift piles at the bottom of the tunnel, and only two tidal dams and two ti...

Abstract

The invention discloses a construction method of a highway tunnel in a tidal tidal area of ​​a sea flat, and belongs to the field of construction. Based on the experience of the water conservancy department in sea flat reclamation and land reclamation, the invention first entrusts the water conservancy department to build a sea flat tide prevention and control dam according to the outer edge of the road tunnel design line, and then sets up a reliable structure in the tunnel area to prevent sea flat tide seepage and uneven settlement, and cancel the anti-tide dam. Finally, the tunnel structure is constructed according to the design requirements, so as to ensure the quality and safety of the tunnel construction and eliminate the impact of sea tide surges.

Description

technical field [0001] The invention belongs to the field of construction methods, and in particular relates to a method for constructing road tunnels in tide surge areas on sea flats. Background technique [0002] There are a large area of ​​tidal flats in the coastal areas of our country. In recent years, with the rise of land reclamation, more and more tidal flats have begun to be developed. With the expansion of coastal cities, road construction also began to need to cross tidal tidal areas. Generally speaking, the inner side of the highway built in the tidal flat area is usually reclaimed and developed into a new urban area. However, in tidal flat areas, roads are usually crossed in the form of bridges, and bridges crossing tidal tidal areas will affect the new district and ocean scenery, and the effect is not ideal. Therefore, under the new situation, it is proposed that the planning of the new district adopt the road tunnel to cross the tidal tidal zone. But so far...
