Abstract
The utility model discloses a pipeline installation pillar in an oil/gas pipeline tunnel. The pipeline installation pillar comprises a tunnel bottom plate and a concrete pillar arranged on the tunnel bottom plate, wherein the concrete pillar is further provided with a steel pipe clamp; the steel pipe clamp is used for fixing the pipeline through foundation bolts; the concrete pillar is a reinforced concrete pillar; the foundation bolts are steel bolts; the foundation bolts are anchored into basement rock below the tunnel bottom plate; and the surface of the concrete pillar is provided with an arc-shaped groove. The pipeline installation pillar has the advantages that due to the adoption of the pipeline installation pillar, problems caused by direct welding of a steel structure base existing in the conventional installation way of pipelines in tunnels can be solved effectively, construction is easy and convenient, high reliability is realized, and safe operation of pipeline in the tunnel can be ensured; and meanwhile, the using quantity of steel structures is reduced, and expenses are saved.
Description
Technical field
The utility model relates to a kind of oil and gas pipes tunnel interior conduit installation buttress.
Background technique
At present, along with the development of domestic petroleum Gas Transmission Pipeline Project, heavy caliber, long distance oil-gas pipeline need or natural obstacle artificial by various rivers, the mountain ridge etc. more and more, can adopt the Tunnel Passing mode to pass through in most of situation.Tunnel interior conduit mounting and installation mode is generally that earthing lays or buttress lays.When adopting buttress to lay, need to consider buttress, pipe clamp, basement rock three's connection pattern.
The present mounting type of tunnel interior conduit commonly used, employing be that the pre-embedded steel slab of Steel Pipe Clamp pedestal and pipeline buttress end face carries out the mode of directly welding.Present this mode need to be carried out a large amount of welding jobs in narrow limited space in the tunnel, the preservative treatment of weld joint also is difficult to reach designing requirement, and long-term non-maintaining operation produces certain potential safety hazard for the tunnel interior conduit; Simultaneously, all larger for the Steel Pipe Clamp pedestal weight and volume of larger caliber pipeline, the transportation installation in position in the tunnel is all more difficult.
The model utility content
The utility model has overcome shortcoming of the prior art, and a kind of oil and gas pipes tunnel interior conduit installation buttress is provided.
The technical solution of the utility model is: a kind of oil and gas pipes tunnel interior conduit installation buttress, comprise tunnel floor and the concrete buttress that is arranged on tunnel floor, also be provided with Steel Pipe Clamp on concrete buttress, described Steel Pipe Clamp is fixed pipeline by sill anchor.
Described concrete buttress is the reinforced concrete buttress.
Described sill anchor is the steel crab-bolt.
Described sill anchor anchors in the following basement rock of tunnel floor.
Also be provided with arc groove on the concrete buttress surface.
Compared with prior art, the utility model has the advantages that: can effectively solve the problems referred to above that existing tunnel interior conduit mounting type exists, easy construction, reliability is high, can guarantee the safe operation of pipeline in the tunnel, also reduce the steel structure consumption simultaneously, save expense.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of oil and gas pipes tunnel interior conduit is installed buttress, as shown in Figure 1, comprise: tunnel floor 1 and the reinforced concrete buttress 2 that is arranged on tunnel floor 1, be provided with arc groove on reinforced concrete buttress 2 surfaces, in order to support and the constraint oil and gas pipes, also be provided with Steel Pipe Clamp 4 on reinforced concrete buttress 2, described Steel Pipe Clamp 4 fixes oil and gas pipes by the sill anchor 3 that anchors in the following basement rock of tunnel floor 1.
Described sill anchor 3 is the steel crab-bolt.
