Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction, especially a permanent and temporary combined road structure for construction site. BACKGROUND
[0002] In house building projects, the housing bureau strictly manages dust control and management, and requires that the construction site must be hardened. During the later garden construction, the temporary concrete road needs to be broken, and the temporary road debris needs to be transported out of the site, causing waste of materials and human resources.
[0003] After searching, the Chinese patent with publication number CN217298502U discloses a permanent and temporary combined road structure for house building construction site, which is sequentially laid from bottom to top with backfill layer, cement stabilized gravel layer and concrete layer. The backfill layer has a sleeve and a rain and sewage corrugated pipe buried inside. The cement stabilized gravel layer has a double-layer bidirectional steel bar laid on top. The double-layer bidirectional steel bar is cast and fixed in the concrete layer. A separation joint is formed on the concrete layer. A surface layer can be laid on top of the concrete layer, which is made of permeable asphalt concrete or concrete.
[0004] The road structure ensures reliable bearing capacity, uses less concrete, has a short construction period, and can be used as a temporary road. A surface layer can be laid on top of the concrete layer, so that the structure can be used as a permanent road, avoiding re-excavation and material waste.
[0005] However, the device still has the following problems:
[0006] In actual use, the sleeve and corrugated pipe are directly buried in the backfill layer. After multiple layers of concrete are poured on top, the weight of the concrete on top will exert pressure on the sleeve and corrugated pipe, which may cause damage or even rupture of the pipes. The moisture and chemicals in the concrete may also cause corrosion of the pipes, so the pipes need to be protected. UTILITY MODEL CONTENTS
[0007] To solve the above technical problems, the utility model provides a permanent and temporary combined road structure for construction site, which has a protective sleeve outside the sleeve and corrugated pipe. The protective sleeve can protect the sleeve and corrugated pipe from external pressure after multiple layers of concrete are poured, preventing damage or even rupture. The protective sleeve also reduces the corrosion of the sleeve and corrugated pipe caused by moisture and chemicals in the concrete, prolonging the service life.
[0008] The technical solution that realizes the utility model discloses a construction site permanent and temporary combined road structure, which comprises a lime-soil layer, a gravel layer is arranged on the upper side of the lime-soil layer, a concrete layer is poured on the upper side of the gravel layer, a penetration layer is arranged on the upper side of the concrete layer, and a seal layer is arranged on the upper side of the penetration layer.
[0009] In some embodiments, the upper side of the two protective sleeves is fixedly connected with a plurality of reinforcing steels at equal intervals, and two connecting steels are symmetrically fixedly connected between the two adjacent reinforcing steels.
[0010] In some embodiments, the inner side of the concrete layer is pre-buried with a plurality of transverse steels at equal intervals.
[0011] In some embodiments, the penetration layer is specifically made of emulsified asphalt.
[0012] In some embodiments, the seal layer is specifically made of fine-grained asphalt.
[0013] In some embodiments, the compaction degree of the gravel of the gravel layer is not less than 98%.
[0014] Compared with the prior art, the utility model has the following advantages:
[0015] Firstly, the protective sleeve is arranged on the outer side of the sleeve pipe and the corrugated pipe, so that the sleeve pipe and the corrugated pipe can be protected after the subsequent multi-layer concrete pouring, the sleeve pipe and the corrugated pipe are prevented from being damaged or even broken due to external pressure, and the corrosion of the sleeve pipe and the corrugated pipe caused by water and chemicals in the concrete is reduced, and the service life is prolonged.
[0016] Secondly, the lime-soil layer, the gravel layer and the concrete layer are laid, so that the utility model can be used as a temporary road, a plurality of transverse steels are pre-buried in the inner side of the concrete layer at equal intervals, a plurality of reinforcing steels are fixedly connected to the outer side of the two protective sleeves at equal intervals, and two connecting steels are symmetrically fixedly connected between the two adjacent reinforcing steels, so that the compressive strength of the temporary road is effectively improved, and when the temporary road needs to be used as a permanent road, the penetration layer and the seal layer can be directly laid on the concrete layer.
[0017] The problem that the sleeve pipe and the corrugated pipe cannot be protected and the temporary road needs to be broken and removed during the subsequent construction is solved, and the waste of materials and human resources caused by the removal of the temporary road is avoided.
