Description

Construction enclosure and channel protection way arrangement method based on road reconstruction engineering Technical Field The invention relates to the technical field of construction of road reconstruction projects, in particular to a construction enclosure and a channel protection way arrangement method based on the road reconstruction projects. Background With the further improvement of the urban degree of China, the original roads in more and more cities can not meet the increasing demand of traffic, and the road reconstruction and expansion projects are increased, especially the form of old road expansion and new bridge becomes the first choice of a plurality of cities. However, the road reconstruction and expansion in the city is often difficult to completely interrupt traffic and close the construction site, and a reserved channel protection way for the coming and going of the social vehicles is needed, so that how to scientifically and reasonably arrange the site construction enclosure and the channel protection way, and further ensure that the engineering progress is not influenced and the requirements of the social vehicles on passing can be met to the greatest extent are the urgent problem of engineering technicians. Disclosure of Invention Aiming at the prior art, the invention provides a construction enclosure and a channel protection way arrangement method based on a road reconstruction project. The invention provides a construction enclosure and a channel protection way arrangement method based on a road reconstruction project, which comprises the following steps: S1, constructing a lower structure of a new bridge, wherein the lower structure of the new bridge comprises a new bridge pile foundation, a new bridge bearing platform and a new bridge pier, the new bridge pier is arranged at the upper end of the new bridge bearing platform, the new bridge bearing platform is arranged at the upper end of the new bridge pile foundation, and when a construction enclosure is arranged, a foundation pit excavation side line of the new bridge bearing platform is used as a construction enclosure arrangement control line; S2, constructing a cast-in-situ beam at the upper part of the newly-built bridge, namely erecting a support frame and a scaffold, and constructing the cast-in-situ beam at the upper part of the newly-built bridge, wherein the widths of the support frame and the scaffold after being erected are larger than the widths of the top surfaces of the cast-in-situ beams at the upper part of the newly-built bridge; S3, dividing the ground road into two parts, namely a left part and a right part according to two opposite directions of vehicle running, and carrying out the construction of changing the road, wherein the construction of changing the road is that after the construction of the right part is completed, a construction enclosure of the right part is changed to the left part, the construction of the left part is carried out after the left part is closed, a channel protection way is arranged on the right part of the road which is completed, and if the left part is firstly constructed, the construction is carried out, and the construction is carried out after the left part is completed, the construction is also carried out after the left part is converted to the right part. In the S1, the setting position of the protection passage way on the cross section is judged according to the relative position of the newly built bridge bearing platform and the existing ground road, and the two situations are classified as one of the newly built bridge bearing platform center line and the existing ground road center line, wherein after a construction space of the lower structure of the newly built bridge is reserved, when the distance from the existing ground road side line is still provided, the middle part of the road cross section is closed by adopting a construction fence, the two sides of the protection passage way are respectively set according to a single-lane motor vehicle lane and a single-lane non-motor vehicle lane by utilizing the existing ground road or the newly built temporary road, and the two sides of the protection passage way are respectively set according to the single-lane motor vehicle lane and the single-lane non-motor vehicle lane. In the S2, after the construction of the lower structure of the newly built bridge is completed, the construction fence is moved, and the construction fence is moved and the corresponding construction fence in the S1 is divided into two cases, namely, the construction fence in the S1 is expanded outwards along the width direction of the road, the widths of the support frame and the scaffold of the cast-in-situ beam at the upper part of the newly built bridge are reserved, the original reserved passage way is occupied after the construction fence is expanded outwards, the motor vehicle lane can not pass through at the moment, only the reserved passage w
