Abstract
Description
Technical Field
[0001] The present application relates to the technical field of construction engineering, and in particular to a permanent and temporary combined road structure suitable for factory load transportation. Background Art
[0002] During construction, temporary roads are usually built to meet the construction needs of the project. The combination of permanent and temporary is to plan and put permanent projects into use in advance to meet the construction needs of the project and reduce the investment in temporary facilities, thereby achieving the goal of reducing costs and increasing efficiency.
[0003] Common temporary road structures include concrete surface layer, cement stabilized gravel layer and soil layer. During construction, the soil is compacted to form a soil layer, and then a cement stabilized gravel layer is laid on the soil layer. Then, the concrete surface layer is poured on the cement stabilized gravel layer. During pouring, the concrete is rammed in blocks, vibrated to make it dense, and smoothed as it is rammed. This completes the construction of temporary roads.
[0004] The above-mentioned existing technical solutions have the following defects: the current common permanent road construction requires the demolition of temporary construction roads in the later stage before the construction of permanent roads. The excavation and demolition work is large, which affects the construction progress and has high construction costs. Therefore, there is room for improvement. Utility Model Content
[0005] In order to improve the construction progress of the permanent-temporary combined road and reduce the construction cost, the present application provides a permanent-temporary combined road structure suitable for factory load transportation.
[0006] The present application provides a permanent and temporary combined road structure suitable for factory load transportation, which adopts the following technical solutions:
[0007] A permanent and temporary combined road structure suitable for factory load transportation, comprising a soil layer, a cushion layer, a cement-stabilized gravel layer, a temporary construction road surface layer and a permanent road reinforced concrete surface layer, wherein permanent water and electricity pipelines are pre-buried in the soil layer, the cushion layer is arranged above the soil layer, the cement-stabilized gravel layer is arranged above the cushion layer, the temporary construction road surface layer is arranged above the cement-stabilized gravel layer, and the permanent road reinforced concrete surface layer is arranged above the temporary construction road surface layer.
[0008] By adopting the above technical solution, Yonglin combined the road structure to pre-buried permanent water and electricity pipelines for later use during the temporary construction road stage, and backfilled and compacted the cushion layer and cement-stabilized gravel layer of the permanent road structure in layers. During the later construction of the permanent road in the factory building, the permanent road reinforced concrete layer can be directly laid on the temporary construction road surface, which reduces the situation where the temporary road is demolished in the later stage to affect the construction progress and saves construction costs.
[0009] Preferably, a geogrid is laid on the mattress layer.
[0010] By adopting the above technical solution, the geogrid can reinforce the cushion layer, enhance the stability of the cushion layer and extend its service life.
[0011] Preferably, the thickness of the soil layer is greater than the thickness of the cement-stabilized gravel layer.
[0012] By adopting the above technical solution, the thickness of the soil layer is set to be greater than the thickness of the cement-stabilized gravel layer, so that the Yonglin road structure has a better supporting foundation and the strength of the Yonglin road structure is improved.
[0013] Preferably, the thickness of the cement-stabilized gravel layer is greater than the thickness of the mattress layer.
[0014] By adopting the above technical solution, the thickness of the cement-stabilized gravel layer is set to be greater than the thickness of the cushion layer, so that the Yonglin road structure has better compressive strength and reduces the occurrence of collapse.
[0015] Preferably, the permanent water and electricity pipeline is pre-buried in the middle position in the longitudinal direction of the soil layer.
[0016] By adopting the above technical scheme, the permanent water and electricity pipeline is pre-buried in the middle position of the soil layer in the longitudinal direction. The permanent water and electricity pipeline is at an appropriate distance from the cement stabilized gravel layer and the bottom of the soil layer, so that the cement stabilized gravel layer is not easy to squeeze the permanent water and electricity pipeline, and the operating personnel do not need to dig too deep into the soil layer to pre-bury the permanent water and electricity pipeline, which can play a protective role for the permanent water and electricity pipeline and facilitate construction.
[0017] Preferably, a plurality of the permanent water and electricity pipelines are provided, and the plurality of the permanent water and electricity pipelines are arranged at intervals.
[0018] By adopting the above technical solution, several permanent water and electricity pipelines are set at intervals so that waterways and electricity lines can be laid at regular intervals along the length of the permanent and temporary combined road, which improves the applicability and convenience and is facilitating subsequent construction and building planning.
[0019] Preferably, the thickness of the cement-stabilized crushed stone layer is greater than the thickness of the temporary construction road surface layer.
[0020] By adopting the above technical solution, the thickness of the temporary construction road surface layer is less than the thickness of the cement stabilized gravel layer. Since the permanent road reinforced concrete surface layer will be poured on the temporary road surface layer in the future, the appropriate thickness of the temporary construction road surface layer can not only ensure the strength of the road but also save construction materials and reduce costs.
[0021] Preferably, the thickness of the cement-stabilized crushed stone layer is greater than the thickness of the permanent road reinforced concrete surface layer.
[0022] By adopting the above technical solution, the thickness of the cement-stabilized gravel layer is greater than the thickness of the permanent road reinforced concrete surface layer. The bottom layer of the permanent-temporary combined road structure has good strength, and the permanent road reinforced concrete surface layer can be cast relatively thinner, which is smaller than the cement-stabilized gravel layer, saving materials and thus costs.
[0023] To sum up, the present application includes at least one of the following beneficial technical effects: the permanent and temporary combined road structure pre-buries permanent water and electricity pipelines to be used later in the temporary road construction stage, and the cushion layer and cement-stabilized gravel layer of the permanent road structure are layered backfilled and compacted. When the permanent road of the factory building is constructed in the later stage, the permanent road reinforced concrete layer can be directly laid on the temporary construction road surface layer, which reduces the situation where the temporary road is demolished in the later stage to affect the construction progress and saves construction costs.

[0027] The following is combined with Figure 1-2 This application is described in further detail.
[0028] The present application embodiment discloses a permanent and temporary combined road structure suitable for factory load transportation. Figure 1 and Figure 2 A temporary and permanent road structure suitable for factory load transportation includes a soil layer 1, a cushion layer 2, a cement stabilized gravel layer 3, a temporary construction road surface layer 4 and a permanent road reinforced concrete surface layer 5. A permanent water and electricity pipeline 6 is pre-buried in the soil layer 1, and the permanent water and electricity pipeline 6 is pre-buried in the middle position in the longitudinal direction of the soil layer 1. The permanent water and electricity pipeline 6 is arranged horizontally, and a plurality of permanent water and electricity pipelines 6 are arranged, and the plurality of permanent water and electricity pipelines 6 are arranged at intervals. The cushion layer 2 is arranged above the soil layer 1, and a geogrid 7 is laid on the cushion layer 2. The cement stabilized gravel layer 3 is laid above the cushion layer 2, the temporary construction road surface layer 4 is laid above the cement stabilized gravel layer 3, and the permanent road reinforced concrete surface layer 5 is cast above the temporary construction road surface layer 4.
[0029] Correspondingly, during the construction stage of the temporary construction road, the soil layer 1 is excavated to pre-embed the permanent water and electricity pipeline 6. After the permanent water and electricity pipeline 6 is pre-embedded, the soil layer 1 is compacted, the cushion layer 2 is replaced and compacted, and then the geogrid 7 is laid, and then the cement stabilized gravel layer 3 is laid. The cement stabilized gravel layer 3 is backfilled and compacted in layers, and then the temporary construction road surface layer 4 is laid and cast on the cement stabilized gravel layer 3. Later, the permanent road reinforced concrete surface layer 5 is cast on the temporary construction road surface layer 4. The permanent and temporary combined road structure pre-buries the permanent water and electricity pipeline 6 used later in the temporary construction road stage, and backfills and compacts the cushion layer 2 and cement stabilized gravel layer 3 of the permanent road structure in layers. During the later construction of the permanent road of the factory building, the permanent road reinforced concrete layer 1 can be directly laid on the temporary construction road surface layer 4, which reduces the situation where the temporary road is broken in the later stage to affect the construction progress and saves construction costs.
[0030] Furthermore, the thickness of the soil layer 1 is greater than the thickness of the cement stabilized gravel layer 3. The thickness of the cement stabilized gravel layer 3 is greater than the thickness of the cushion layer 2, the temporary construction road surface layer 4 and the permanent road reinforced concrete surface layer 5. The thickness of the cushion layer 2, the temporary construction road surface layer 4 and the permanent road reinforced concrete surface layer 5 is not much different. The soil layer 1 is the foundation of the entire road, and the thickness is set to the thickest so that the permanent road structure has a better supporting foundation and improves the strength of the permanent road structure. The cement stabilized gravel layer 3 is the main compressive structure of the road. The thickness of the cement stabilized gravel layer 3 is set to be greater than the thickness of the cushion layer 2, the temporary construction road surface layer 4 and the permanent road reinforced concrete surface layer 5, so that the permanent road structure has better compressive strength and reduces the occurrence of collapse. The reasonable setting of the thickness of the cushion layer 2, the temporary construction road surface layer 4 and the permanent road reinforced concrete surface layer 5 can not only ensure the strength of the road but also save construction materials and reduce costs.
[0031] The implementation principle of a permanent and temporary combined road structure suitable for factory load transportation in the present application embodiment is as follows:
[0032] During construction, the soil layer 1 is excavated to pre-embed the permanent water and electricity pipeline 6. After the permanent water and electricity pipeline 6 is pre-embedded, the soil layer 1 is compacted, the cushion layer 2 is replaced and compacted, and then the geogrid 7 is laid, and then the cement stabilized gravel layer 3 is laid. The cement stabilized gravel layer 3 is backfilled and compacted in layers, and then the temporary construction road surface layer 4 is laid and cast on the cement stabilized gravel layer 3. Later, the permanent road reinforced concrete surface layer 5 is cast on the temporary construction road surface layer 4. The permanent and temporary combined road structure pre-buries the permanent water and electricity pipeline 6 used later in the temporary construction road stage, and backfills and compacts the cushion layer 2 and cement stabilized gravel layer 3 of the permanent road structure in layers. When the permanent road of the factory building is constructed in the later stage, the permanent road reinforced concrete layer 1 can be directly laid on the temporary construction road surface layer 4, which reduces the situation where the temporary road is broken in the later stage to affect the construction progress and saves construction costs.
[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
