Embodiment

[0046] The present invention is used for tunnel construction under shallow water and land conditions by the mobile cofferdam open cut method, comprising the following steps:

[0047] 1) to form a weir body;

[0048] The weir body enclosed by the tunnel construction includes a construction body 1, a demolition body 2 and a construction body 3. The construction body 1 is the weir body at the tunnel construction site, and is divided by a side partition 8 and a full-end partition 5a (such as Figure 23 , Figure 24 shown) and A profiling end face partition 6a (such as Figure 25 As shown), the demolition body 2 is the weir body in the demolition process, which is surrounded by the side partition 8 on the left side of the construction body 1, the A profiled end face partition 6a and the B profiled end face partition 6b, and the construction body 3 It is the weir body in the construction process, surrounded by the side partition 8 on the right side of the construction body 1, the ...

Abstract

The invention discloses an I-type sheet pile for tunnel construction. The I-type sheet pile for tunnel construction comprises load bearing bodies 4-1, sheet piles 4-3 and a supporting cross beam 4-4, wherein the load bearing bodies 4-1 are symmetrically arranged on the two sides of the supporting cross beam 4-4, the sheet piles 4-3 is arranged at the lower ends of the load bearing bodies 4-1, splicing units are arranged at the two ends of the I-type sheet pile 4, when the I-type sheet piles 4 are spliced, a first filling area 4-8 is formed between every two splicing units, and the first filling areas 4-8 are filled with filler for sealing water. The I-type sheet pile for tunnel construction has the advantages that the construction period can be shortened, construction cost can be lowered, waterway traffic cannot be influenced in a wide water area, tunnel construction of long distance and extra-long distance can be achieved, an excavation area is smaller, excavated earth volume is smaller, and influences to the environment is small.

Description

technical field [0001] The invention relates to an I-type sheet pile that can be used for tunnel construction, and belongs to the technical field of tunnel construction. Background technique [0002] Existing tunnel construction usually takes a long construction period, costs a lot, and has a great impact on the environment. Therefore, shortening the construction period, reducing construction costs, improving the construction environment, and reducing environmental impact have always been urgent problems in the tunnel industry. Contents of the invention [0003] The present invention proposes I-type sheet piles for tunnel construction. Its purpose is to overcome the above-mentioned defects in the prior art, shorten the tunnel construction period; reduce construction costs; , technical difficulties in constructing tunnels on land or in medium and deep water conditions. [0004] The technical solution of the present invention: I-type sheet piles for tunnel construction, it...
