Problems solved by technology

The arc-shaped gate in the prior art is usually one-way water retaining, and its structure is: the gate is composed of a door leaf structure, a support arm and a support hinge. When opening and closing, the gate leaf structure rotates around the center of the support hinge. This kind of gate cannot Helicopter opening and closing, the length of the gate pier increases the amount of reinforced concrete works, and the gate span is small. When the gate span is large, there are defects such as gate self-heavyness and low rigidity

Embodiment 1

[0027] Such as Figure 1-Figure 5 As shown, it is a double-arch gate, one side of the gate faces the sea, and the other side is the Perfume River. The gate includes a door body and embedded parts. The truss girder system, prestressed tie rods 15, and box-shaped end columns 16 arranged on the left and right sides of the gate. The truss beam system includes a plurality of upper chord arch tubes 4 arranged at intervals from top to bottom, and a plurality of lower chord arch tubes 5 arranged at intervals from top to bottom in sequence, and the two ends of each upper chord arch tube 4 and lower chord arch tube 5 are respectively Connected with the box-shaped end columns 16 on the left and right sides of the gate, the arching direction of the upper chord arch tube 4 and the lower chord arch tube 5 are opposite, forming an olive-shaped double arch structure in the plan view, and the upper chord arch tube 4 passes through multiple The two vertical connecting pipes 25 are connected, t...

Embodiment 2

[0033] Such as Figure 6-Figure 8As shown, this embodiment is basically the same as Embodiment 1, the difference is that the upper chord arch tube 4 in this embodiment includes an arched upper beam 23 arranged on the upper part and a plurality of arched beams 23 arranged on the lower part in turn. Bending into arched steel pipes, the panel 1 is directly welded together with the last beam 23 and one side of the steel pipes, and the last beam 23 and each steel pipe are connected together by longitudinal beam webs 24. In this embodiment, the upper beam 23 constituting the upper chord arch tube 4 is made of I-beam, and the steel pipe is made of a square tube or a rectangular tube or a box-shaped structure.

[0034] Other parts in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a double-arch gate. The double-arch gate comprises a gate body and an embedded part. The gate body comprises an arch-shaped panel, a truss girder system and box-shaped end columns which are arranged on the right side and the left side of the gate. The truss girder system comprises multiple upper truss arch pipes and multiple lower truss arch pipes. The two ends of each upper truss arch pipe and the two ends of each lower truss arch pipe are connected with the box-shaped end columns which are arranged on the right side and the left side of the gate. The arch directions of the upper truss arch pipes and the lower truss arch pipes are opposite. The upper truss arch pipes are connected with the lower truss arch pipes through multiple web member trusses. The panel is fixedly connected with the upper truss arch pipes of the truss girder system. Reverse supporting sliding blocks and side water seals are fixed to the front sides of the box-shaped end columns. Forward supporting sliding blocks and side sliding blocks are fixed to the rear sides of the box-shaped end columns. The lower portion of the panel is provided with a bottom water seal. The embedded part comprises a main supporting railway, a reverse supporting railway and a bottom rail. The forward supporting sliding blocks and the reverse supporting sliding blocks are matched with the main supporting railway and the reverse supporting railway in a corresponding mode respectively. The stress condition is good, and the loading capacity is high.

Description

technical field [0001] The invention relates to a gate, in particular to a double-sided arched gate. Background technique [0002] The gate is a control facility for closing and opening the discharge channel, which can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc. At present, gates commonly used in water conservancy projects include plane gates and arc gates, and what the present invention relates to are arc gates. The arc-shaped gate in the prior art is usually one-way water retaining, and its structure is: the gate is composed of a door leaf structure, a support arm and a support hinge. When opening and closing, the gate leaf structure rotates around the center of the support hinge. This kind of gate cannot Helicopter opening and closing, the length of the gate pier increases the amount of reinforced concrete works, and the gate span is small. When the gate span is large, there are defects such as gate s...
