Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and in particular relates to a hollow inverted arch trestle. Background Art

[0002] The tunnel trestle is a temporary bridge during the tunnel construction process. During the tunnel construction process, the construction of the invert includes four parts: tunnel bottom excavation, initial support, invert secondary lining and invert filling. In order to ensure the normal construction of the upper and lower guides during the invert construction process, a self-made tunnel trestle is used in the invert construction area to ensure the normal passage of construction machinery, equipment, materials and personnel. In actual use, passing vehicles, equipment and personnel are likely to bring soil and gravel to the trestle, and mud and sand are likely to accumulate on the bridge deck, causing vehicles to slip easily and have difficulty getting on the bridge, affecting the construction process. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a hollow inverted arch trestle. By arranging leakage holes on the bridge deck, sand and gravel can fall from the bridge deck to the placement plate, which solves the problem that the bridge deck is prone to slipping due to mud accumulation. The placement plate can also collect mud and sand, so as to facilitate the cleaning of the mud and sand.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] A hollow inverted arch trestle comprises a pair of trestle units which are arranged side by side. The trestle units comprise arch bridge sections and supporting bridge sections which are stacked up and down. There is a spacing space between the arch bridge sections and the supporting bridge sections. The arch bridge sections are provided with leakage holes. A plurality of placement plates are arranged in the spacing space. The placement plates are used to receive stones and mud falling from the leakage holes.

[0006] The storage board is arranged in an inclined manner, and the inclined bottom end of the storage board extends out of the spacing space and faces the outside of the trestle unit.

[0007] The outer end of the storage board is hingedly configured on the supporting bridge section, and the bottom of the inner end of the storage board is provided with a lifting cylinder, which is fixed to the supporting bridge section, and the driving end of the lifting end is connected to the storage board.

[0008] Baffles are respectively arranged on both sides of the storage plate.

[0009] A guardrail is arranged on the outer side of the arched bridge section.

[0010] The guardrail comprises a plurality of railings, which include an insertion rod fixedly arranged on the outside of the arch bridge section, and a riser inserted and arranged on the insertion rod.

The top surfaces of the arc-shaped longitudinal beams form a bridge deck, and the bridge deck is provided with a plurality of anti-skid strips which are arranged transversely, and the leakage holes are formed between adjacent anti-skid strips.

[0012] The supporting bridge section includes a plurality of supporting longitudinal beams which are arranged at equal intervals. A plurality of cross beams are arranged in the interval space. The top of the cross beam is connected to the arc-shaped longitudinal beam, and the bottom of the cross beam is connected to the supporting longitudinal beam.

[0013] The technical solution of the utility model has at least the following advantages and beneficial effects:

[0014] (1) The utility model provides leakage holes on the bridge deck, so that sand and gravel can fall from the bridge deck to the storage plate, thereby solving the problem of slippery mud on the bridge deck. The storage plate can collect mud and sand to facilitate cleaning. In addition, the storage plate can be tilted to discharge mud and sand from the side of the pier, thereby achieving a self-cleaning effect of mud and sand.
