Abstract

The invention provides a construction process of a road with a pipeline well, which comprises the steps of digging and cleaning a roadbed, laying a base layer, shaping the base layer, pouring concrete and constructing a cement concrete surface layer, wherein a pipeline well sleeve is prefabricated in a factory before the concrete is poured, the side edge of the pipeline well sleeve is a straight plane, the prefabricated pipeline well sleeve is sleeved outside the pipeline well, the upper surface of the pipeline well sleeve is flush with the pipeline well as far as possible, the concrete is poured after the pipeline well sleeve is sleeved, and then the normal cement concrete surface layer construction is carried out. According to the invention, in the construction of the road with the pipe shaft, the prefabricated square pipe shaft sleeve is sleeved outside the pipe shaft, and then the concrete pouring operation is carried out, so that the concrete around the pipe shaft is vibrated more conveniently and quickly, no trace is left, and the road surface is smoother.

Description

Construction process for well road with pipeline

Technical Field

The invention belongs to a road construction process, and particularly relates to a construction process of a road with a pipe well.

Background

At present, when a road with a pipe well is constructed, because the pipe well is generally of a circular structure, concrete vibration at the edge of the pipe well is inconvenient when concrete is poured, traces in the vibration moving process are easy to appear, the road surface is uneven, the attractiveness is affected, and the driving comfort is affected.

Disclosure of Invention

The invention aims to solve the technical problem of providing a construction process for a road with a pipe well.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a construction process for pipeline with pipeline well includes such steps as excavating and cleaning road bed, laying basic layer, shaping basic layer, pouring concrete, constructing cement concrete surface layer, prefabricating pipeline well sleeve, sleeving the prefabricated pipeline well sleeve outside pipeline well, making the upper surface of pipeline well sleeve flush with pipeline well, pouring concrete after sleeving, and constructing cement concrete surface layer.

The side of the pipe well external member is provided with a steel bar protruding out of the surface, and the steel bar is embedded in the pipe well external member.

The side of the pipeline well sleeve is provided with an inwards concave slotted hole.

The slotted hole and the reinforcing steel bar are coaxially arranged.

And a transverse strip-shaped groove is processed on the side surface of the pipe well sleeve.

The invention has the beneficial effects that: according to the invention, in the construction of the road with the pipe shaft, the prefabricated square pipe shaft sleeve is sleeved outside the pipe shaft, and then the concrete pouring operation is carried out, so that the concrete around the pipe shaft is vibrated more conveniently and quickly, no trace is left, and the road surface is smoother.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1 and 2, a construction process for a pipeline with a pipeline well comprises the steps of excavating and cleaning a roadbed, laying a base layer, shaping the base layer, pouring concrete and constructing a cement concrete surface layer, wherein the processes are the prior art and are not described too much, a pipeline well sleeve is prefabricated in a factory before the concrete is poured, the side edge of the pipeline well sleeve is a straight plane, the whole pipeline well sleeve in the embodiment is of a cuboid structure, a through hole 1 for embedding the pipeline well is formed in the middle of the pipeline well sleeve, the prefabricated pipeline well sleeve is sleeved outside the pipeline well, the upper surface of the pipeline well sleeve is flush with the pipeline well as much as possible, the concrete is poured after the pipeline well sleeve is sleeved, and then the construction of the normal cement concrete surface layer is carried out. In order to reduce the possibility of water inflow in the pipe well, the middle of the pipe well sleeve is high and low in periphery, and the height difference is controlled within 5cm, so that the influence on a travelling crane is small, accumulated water at the periphery of the pipe well can be reduced, the possibility of water inflow in the pipe well is reduced, and the waterproof requirement on the pipe well can be slightly reduced.

In order to better combine with the concrete that pours afterwards for the piping shaft external member, will the piping shaft external member side be equipped with the reinforcing bar 2 of protrusion in this surface, reinforcing bar 2 is pre-buried in the piping shaft external member, reinforcing bar 2 partly extend to the piping shaft outside can be with the concrete that pours after and combine together, if the road surface has laying reinforcing bar 2, can also weld with reinforcing bar 2, increase joint strength between them, make follow-up not produce the crack or reduce the crack. In the further embodiment, the side surface of the pipe well sleeve is provided with an inwards concave slotted hole 3. Further, the slot 3 is arranged coaxially with the reinforcement bar 2. Further, a transverse strip-shaped groove 4 is machined on the side surface of the pipe well sleeve. The strip-shaped groove 4 is arranged to fill the later poured concrete therein, so that the connection between the two is strengthened.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to explain the principles of the invention, and that various modifications and alterations can be made by those skilled in the art without departing from the spirit and scope of the invention.
