Abstract

The invention discloses a non-earthing open cut tunnel structure along river; including box, pile foundation, top weight structure, bottom counter weight structure, flood control wall and scour protection riprap structure, the pile foundation is installed on the riverbed, the installation of box is on pile foundation upper end, and the interior upper portion of box is provided with the case groove, the interior upper portion of box is provided with multiunit slotted hole, and top weight structure sets up on the case groove, and bottom counter weight structure sets up in the slotted hole, and flood control wall sets up at a side of box, and scour protection riprap structure sets up at wherein another side of box. According to the invention, on the premise of meeting the river flood discharge requirement, the river space on one side close to the flood control wall is fully utilized, and the open cut tunnel box body along the river is implemented, so that the traffic capacity along the river city along the river direction can be greatly improved, and the traffic jam condition is relieved; the self-weight combined counterweight and the weight are adopted to resist the buoyancy of the box body, so that the repeated stress conditions of compression resistance and pulling resistance of pile foundations are avoided, and the service life of the tunnel structure is prolonged.

Description

Non-earthing open cut tunnel structure along river

Technical Field

The invention relates to the technical field of tunnels, in particular to a non-earthing open cut tunnel structure along the river.

Background

At present, all implemented or planned river-crossing, river-crossing and land-based tunnels generally adopt shield tunnels, thick-earth open-cut tunnels or open tunnels. The tunnel plays an important role in the traffic field between cities or areas, and has a wide application range. However, there is a great restriction on road traffic along the river city, especially road traffic along the river direction, and traffic jams are serious in rush hours; the space in the river, especially the space of the river bed near the flood control wall, is often not fully utilized.

Thus, in road traffic schemes along cities, especially open cut tunnel schemes along rivers, it is a difficult problem for the implementation of tunnels between cities or regions.

Those skilled in the art are directed to solving the above-mentioned technical drawbacks.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, the technical purpose of the present invention is to provide a new tunnel arrangement selection scheme for supporting the traffic dispersion along the river city, which can fully utilize the river channel space in the vicinity of the flood control wall.

In order to achieve the technical aim, the invention provides a non-earthing open cut tunnel structure along river, which comprises a box body, a pile foundation, a top weighting structure, a bottom weighting structure, a flood control wall and an anti-scouring and stone-throwing structure, wherein the pile foundation is arranged on a riverbed, the box body is arranged at the upper end of the pile foundation, a box groove is formed in the inner upper part of the box body, a plurality of groups of slotted holes are formed in the inner lower part of the box body, the top weighting structure is arranged on the box groove, the bottom weighting structure is arranged in the slotted holes, the flood control wall is arranged on one side of the box body, and the anti-scouring and stone-throwing structure is arranged on the other side of the box body.

Preferably, the pile foundation is provided with several.

Preferably, two groups of box holes are formed in the box body.

Preferably, the tank body is provided with a culvert between two tank holes.

Preferably, the box body is of an uncovered structure.

The invention has the beneficial effects that:

according to the structure, on the premise of meeting the river flood discharge requirement, the river space on one side close to the flood control wall is fully utilized, the open cut tunnel box body along the river is implemented, the traffic capacity along the river city along the river direction can be greatly improved, and the traffic jam condition is relieved; the self-weight combined counterweight and the weight are adopted to resist the buoyancy of the box body, so that the repeated stress conditions of compression resistance and pulling resistance of the pile foundation are avoided, the stress performance of the tunnel structure and the pile foundation is greatly improved, the service life of the tunnel structure is prolonged, and the tunnel structure has very strong practicability.

The conception, specific structure, and technical effects of the present invention will be further described with reference to the accompanying drawings to fully understand the objects, features, and effects of the present invention.

Drawings

Fig. 1 is a structural diagram of the present invention.

Detailed Description

As shown in FIG. 1, in a concrete embodiment of the invention, the non-earthing open cut tunnel structure comprises a box body 1, a pile foundation 2, a top weighting structure 3, a bottom weighting structure 4, a flood control wall 6 and an anti-scouring and stone-throwing structure 5, wherein the pile foundation 1 is arranged on a river bed 7, the box body 1 is arranged at the upper end of the pile foundation 2, a box groove is formed in the inner upper part of the box body 1, a plurality of groups of slots are formed in the inner lower part of the box body 1, the top weighting structure 3 is arranged on the box groove, the bottom weighting structure 4 is arranged in the slots, the flood control wall 6 is arranged on one side of the box body 1, and the anti-scouring and stone-throwing structure 5 is arranged on the other side of the box body 1.

Further, the pile foundation 2 is provided with a plurality of pile foundations, and two groups of box holes 8 are formed in the box body 1.

Wherein, the box body 1 is provided with a culvert 9 between two box holes 8, the box body 1 is of an uncovered soil structure and is arranged above the riverbed 7 according to the road elevation requirement

According to the invention, on the premise of meeting the river flood discharge requirement, the river space on one side close to the flood control wall is fully utilized, and the open cut tunnel box body along the river is implemented, so that the traffic capacity along the river city along the river direction can be greatly improved, and the traffic jam condition is relieved; the self-weight combined counterweight and the weight are adopted to resist the buoyancy of the box body, so that the repeated stress conditions of compression resistance and pulling resistance of the pile foundation are avoided, the stress performance of the tunnel structure and the pile foundation is greatly improved, the service life of the tunnel structure is prolonged, and the tunnel structure has very strong practicability.

The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
