Detailed Description
The following detailed description of embodiments of the present application will be described in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for increasing compaction around a pipe shaft in a construction road according to an embodiment of the present disclosure, the method at least includes: s1, covering a steel plate on the wellhead of the pipe well; s2, presetting elevation, and positioning and recording the position of the pipe well; s3, comprehensively paving the materials in the roadbed range until the materials reach a preset elevation to form a material layer; the roadbed range comprises a pipe well range, and the material layer comprises a gray soil layer and a water stabilization layer; s4, performing reverse excavation at the position of the pipe well, and removing the materials covered on the pipe well; s5, heightening the pipe well until the pipe well is raised to the height level; s6, presetting a volume, and installing a reinforcing mesh in a reinforcing area after excavating the reinforcing area with the preset volume around the pipe well; s7, performing concrete pouring in the reinforced area to form a concrete layer; and S8, pouring asphalt above the concrete layer to form the asphalt pavement. The method adopts a through-paving through-pressure method to carry out integral construction on the dust and soil around the roadbed and the pipe well, ensures consistent compaction degree in the roadbed construction range, prevents the problem of uneven settlement, and improves the driving comfort of the road.
Referring to fig. 2 to 4, fig. 2 is a top view of a reinforcement around a tubular well according to an embodiment of the present invention, fig. 3 is a sectional view taken along a direction a-B of the reinforcement around the tubular well according to an embodiment of the present invention, and fig. 4 is a sectional view taken along a direction C-D of the reinforcement around the tubular well according to an embodiment of the present invention.
The steel plate 2 is circular, the thickness range of the steel plate 2 is 5-6mm, the diameter of the steel plate 2 is larger than the diameter of the wellhead of the pipe well 1 and smaller than the diameter of the well body of the pipe well 1, and the steel plate 2 can cover the wellhead and cannot extend out of the well body due to the design, so that subsequent paving materials are facilitated, and the well body is heightened. Of course, the shape and thickness of the steel plate 2 may be other, and this embodiment is not described in detail herein. In addition, the steel plate 2 is used for covering the wellhead of the pipe well 1, the problem that external personnel fall into the pipe well 1 by mistake in the construction process is prevented, and potential safety hazards are eliminated.
Alternatively, after the steel plate 2 is covered on the wellhead of the pipe well 1, the surface of the steel plate 2 and the surface of the roadbed are positioned on the same plane.
After the steel plate 2 covers the well mouth, the comprehensive material spreading needs to be carried out in the roadbed range. However, the pipe shaft 1 may be covered after the material is spread, and in order to perform the back excavation on the pipe shaft 1 subsequently, before step S3, the position of the pipe shaft 1 needs to be located and recorded, so as to ensure that the position of the pipe shaft 1 can be determined by recording information subsequently. Alternatively, there are several methods for locating the position of the pipe well 1, for example, locating the position of the pipe well 1 by a GPS locating device, or locating the position of the pipe well 1 by a total station measurement.
Wherein, before locating the position of the tube well 1 through the total station measurement, still include: a measurement point location is determined. Specifically, a measurement point is determined in advance, and the direction of the well 1 relative to the measurement point and the distance from the measurement point to the center point of the well 1 are determined. For example, a measurement point a is determined, the pipe well 1 is located right in front of the point a, and the distance between the point a and the center point of the pipe well 1 is 10 m.
In order to flatten the paved material layer 5, after step S3, the method further includes: the material layer 5 is compacted.
In order to ensure that the thickness of the pipe well 1 is consistent with that of the material paved at other places in the roadbed range, and the compacted pavement is smoother, the step S3 is specifically as follows: and comprehensively paving the materials in the roadbed range according to the loose paving coefficient. The loose coefficient here is set in advance, and the loose coefficient in the range of the pipe well 1 is consistent with the loose coefficient in other places.
After the material layer 5 is compacted, the shaft of the pipe well 1 needs to be heightened, so that the height of the shaft of the pipe well 1 is consistent with that of the surface of the material layer 5, and the constructed road surface is guaranteed to be smooth. Because the pipe well 1 is heightened to the final height at one time instead of being gradually increased to the final height, the working time is greatly shortened, and the construction efficiency is improved.
However, before the pipe well 1 is heightened, the position of the paved pipe well 1 needs to be found. Therefore, before step S4, the method further includes: the location of the pipe well 1 is determined from the previously recorded information. Here, the location of the pipe well 1 may be found directly from a GPS positioning device, or the location of the pipe well 1 may also be found from a previously recorded measurement point location, a direction of the pipe well 1 with respect to the measurement point, and a distance of the measurement point from a center point of the pipe well 1.
After heightening the well bore of the tubular well 1, in order to ensure the firmness of the well bore and prevent the tubular well 1 from settling later, after step S5, the method further comprises: and maintaining the well body of the pipe well 1 and the heightened pipe well 1 by adopting a circular steel sleeve. Specifically, the circular steel sleeves are arranged on the outer walls of the pipe well 1 and the heightened pipe well 1, so that the circular steel sleeves are firmly wrapped on the outer walls of the pipe well 1 and the heightened pipe well 1, and the firmness of the well is improved.
In step S6, after the reinforcement area 3 with a preset volume is excavated around the pipe shaft 1, the reinforcing mesh 4 is installed in the reinforcement area 3, so as to further improve the stability of the pipe shaft 1 and the surrounding area. In the present embodiment, the predetermined volume of the reinforced area 3 is a rectangular parallelepiped with a length, a width and a height of 2.5m, 2.5m and 0.36m, respectively. Of course, in other embodiments, the value of the predetermined volume may be other, and the shape of the reinforcing region 3 is not limited to a rectangular parallelepiped.
Alternatively, in step S7, the strength grade of the concrete 6 is C30.
In conclusion, the embodiment provides a method for improving the compaction degree of the periphery of the pipe well in the construction road, the method adopts a 'through-paving and through-pressing method' to carry out integral construction on the roadbed and the dust and soil around the pipe well, the compaction degree in the roadbed construction range is ensured to be consistent, the problem of uneven settlement is prevented, and the driving comfort degree of the road is improved; and the traditional manual tamping method is replaced, and the economic benefit is improved.
