Background
In recent years, China enters a large-scale infrastructure construction period, newly built projects are difficult to implement subgrades due to steep terrain, bridge proportion is greatly increased, and meanwhile, the phenomena of low utilization rate of original road resources, more protection projects, great influence on the environment along the line and the like generally exist in the process of widening, upgrading and reconstructing the highway.
The method comprises the following steps that (1) widening, upgrading and reconstruction are carried out on a road, when a ground transverse slope is steep, two measures are adopted in the prior art, firstly, an upper slope on the backer side is excavated to achieve the purpose of widening the road; and secondly, a blocking and preventing project is additionally arranged on the lower slope to achieve the purpose of widening the roadbed.
When the new fender of traditional mode construction is prevented engineering, need carry out great excavation to existing side slope or existing road, have a large amount of newly-increased land used and abandon the side, the while is long discontinuous road construction, causes great influence to ecological environment, resident's trip along the line.
In the invention patent application 'a method for widening mountain roads by using cantilever structure', published in 2005, 2.16.7, with publication number CN1580402A, a method for widening mountain roads by using cantilever beams is disclosed, which provides a good idea for widening roads, and a pad beam (1) is used to support cantilever beams (2), concrete precast slabs (3) are laid between the cantilever beams (2), and the anchoring scheme of the cantilever beams (2) at the side close to the mountain is as follows: when the slope is a stable high-quality rock slope, the cantilever beam (2) is directly embedded into the rock body to be used as an anchoring section; setting an anchor rod or a pre-stressed anchor cable (7) as an anchoring point of the cantilever beam (2) for a non-high-quality rock section with better geological conditions; and for the section with poor geological conditions, a concrete balance weight (8) is cast in situ at the backer end of the cantilever beam (2). And the improvement on the structural stability and the construction convenience degree of the concrete pile is necessary.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a convenient quick construction, the better roadbed structure of self stability is provided.
The utility model adopts the technical proposal that: the winged box-type counterweight reinforced concrete roadbed structure comprises a box chamber bottom plate fixedly connected with a foundation, and further comprises a box chamber web plate and a box chamber wing plate fixedly connected with the box chamber bottom plate, wherein the box chamber wing plate extends out of the foundation, a box chamber formed by the box chamber web plate and the box chamber wing plate is of a reinforced concrete structure, and a counterweight is filled in the box chamber.
Furthermore, in order to save the construction period, the box chamber bottom plate, the box chamber web plate and the box chamber wing plate are made of integrated reinforced concrete prefabricated parts.
Further, the box chamber bottom plate is provided with a ground anchor for anchoring the box chamber bottom plate on a foundation so as to enhance the anti-overturning capacity.
Furthermore, the bottom surface of the bottom plate of the box chamber is provided with a counterweight type anti-skidding tooth structure, so that the anti-skidding and anti-overturning capabilities are enhanced.
Further, if the roadbed structure base is in a non-flat state, a leveling layer can be arranged between the foundation and the box chamber bottom plate.
Further, the counterweight is broken stone. The counterweight may also be of a material similar to crushed stone.
Further, the counterweight is soil. The counterweight may also be other materials like soil.
The utility model has the advantages that: the wing plate structure is adopted, so the requirement on the width of the foundation is low, a larger side slope excavation or a higher roadbed retaining structure is not needed, the excavation filling construction amount is small, the influence on the environment caused by the completion of road widening is small, the counterweight structure is adopted, the self-stability can be realized, the requirement on the bearing capacity of the foundation is not high, and the wing plate structure can be used for road construction or road widening.

Labeled as: 1-box wing plate, 2-box web plate, 3-box bottom plate, 4-counterweight, 5-ground anchor, 6-pavement structure, 7-ditch, 8-leveling layer, 9-counterweight type anti-skid tooth, 10-foundation, 11-filling or natural edge slope surface.
Detailed Description
The invention is further described below with reference to the following figures and examples:
as shown in fig. 1 and 2, the utility model discloses a box counter weight reinforced concrete road bed structure of winged box includes the reinforced concrete structure's that comprises chamber bottom plate 3, chamber web 2 and chamber pterygoid lamina 1 of mutual fixed connection, and chamber bottom plate 3 and ground 10 fixed connection, outside chamber pterygoid lamina 1 extended to ground 10, the inside packing of chamber has counterweight 4.
The box chamber bottom plate 3 can be arranged on the foundation 10 such as the existing road or rock-soil foundation, the box chamber bottom plate 3, the box chamber web plate 2, the box chamber wing plate 1 and the pavement structure 6 form a box body together, and the box body is filled with the balance weight 4. The pavement structure 6 is used for bearing the loads of pedestrians, vehicles and other roads; the counterweight 4 filled inside is used for balancing and resisting the bending moment formed by the load borne by the wing plate 1 and supporting the pavement structure 6; the box chamber web 2 is used for transferring the load borne by the box chamber wing plates 1 to the box chamber bottom plate 3.
In order to enable a box body structure formed by the chamber bottom plate 3, the box chamber web plate 2, the box chamber wing plates 1 and the pavement structure 6 to meet the strength requirement and have certain bearing and load transfer capacities, the chamber bottom plate 3, the box chamber web plate 2 and the box chamber wing plates 1 are reinforced concrete members; preferably, the box bottom plate 3, the box web 2 and the box wing plate 1 are made of reinforced concrete prefabricated members, so that the construction period can be shortened, and when the prefabricated members are respectively independent prefabricated members, the mutual fixed connection of the prefabricated members can be referred to by the connection structure of the prefabricated members in the prior art. In case of a convenient transportation section, the box chamber bottom plate 3, the box chamber web plate 2 and the box chamber wing plate 1 can adopt an integrated reinforced concrete prefabricated member.
