Description

Technical Field

[0001] This utility model belongs to the field of road construction technology, specifically relating to a permanent-temporary combined vehicle ferry device for road construction. Background Technology

[0002] During road construction, construction materials are transported by truck to a temporary docking point on the left bank. The trucks then transfer the materials directly to a ferry at the left bank's temporary docking point and transport them to a temporary docking point on the right bank. The materials are then unloaded on the opposite bank, and the trucks return by ferry to the left bank's temporary docking point before departing again. The construction material transportation process is as follows:

[0003] Materials → Transport vehicle → Temporary work site on the left bank → Transport by car ferry to the temporary dock on the opposite bank → Unload materials → Return to car ferry → Return to the temporary dock on the left bank → Leave the temporary dock on the left bank.

[0004] During the transportation of the aforementioned construction materials, considering the already constructed riverside ramp, which is connected to the municipal road, how to provide an unloading point for the transportation of construction materials for the construction of both banks of the national highway during the entire construction period has become a pressing technical problem to be solved, taking into account the shape and structure of the riverside ramp. Utility Model Content

[0005] To solve the technical problems of heavy transport vehicles crossing rivers, and considering the combination of permanent and temporary construction facilities, the purpose of this utility model is to propose a vehicle ferry device that combines permanent and temporary facilities for road construction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A combined permanent and temporary vehicle ferry device for road construction includes multiple layers of gabions arranged along the longitudinal axis of the ferry retaining wall. Each layer contains multiple gabions, with the number of gabions in the upper layer being less than the number in the lower layer, creating a stepped gabion retaining wall along the longitudinal axis. Each gabion is a steel wire woven structure with diamond-shaped mesh. Each gabion contains multiple partitions arranged along its length, dividing the space within the gabion into multiple gabion unit grids. Each gabion unit grid is filled with 150-250mm boulders and hollow concrete blocks. The boulders and hollow concrete blocks are spaced apart within the gabion unit, and the hollow concrete blocks along the river channel form spaced columns with a net distance of 1m.

[0008] The steel wire used for woven gabions is φ2.2mm in diameter, and the steel wire is protected against corrosion by aluminum zinc coating and plastic coating.

[0009] The upper and lower adjacent gabions are bound together with galvanized and plastic-coated steel wire ropes. Specifically, the upper and lower gabions are bound together with galvanized and plastic-coated steel wire ropes at the four corners of the gabion and every 0.5m to enhance the overall vertical stability.

[0010] In each layer of the gabion, the gabions corresponding to the downstream slope are tied to the geogrids pre-embedded in the layers of the downstream slope with wire to enhance the overall horizontal stability. To ensure the anchorage length of the lowest layer of geogrid, it can be extended upwards along the excavated slope by about 2m.

[0011] The present invention proposes a combined permanent and temporary vehicle ferry device for road construction, which, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0012] 1. The gabions in the gabion retaining wall are made of galvanized plastic-coated steel wire mesh with high tensile strength and rigidity, and are corrosion-resistant and rust-resistant. They are filled with crushed stone bags and hollow concrete blocks. The two materials are arranged alternately in the gabion unit to ensure that the gabion retaining wall is aligned with the river channel. The hollow concrete blocks form columns with a net spacing of 1m.

[0013] 2. In the gabion retaining wall, galvanized and plastic-coated steel wire ropes are used to bind (tie) the upper and lower adjacent gabions together; that is, at the four corners of the gabion and every 0.5m, galvanized and plastic-coated steel wire ropes are used to bind the upper and lower gabions together to enhance the overall vertical stability.

[0014] 3. When excavating the bank slope, geogrids are buried in layers. The geogrids are laid from the starting point outside the upper gabion wall. The geogrids in front of the wall and in the backfill soil behind the wall are tied tightly to the gabions to enhance the overall horizontal stability. To ensure the anchorage length of the bottom geogrid, it can be extended upwards along the excavated slope by about 2m.

[0015] 4. At every interval between the longitudinal ends of the retaining wall, gabions are laid horizontally (i.e., perpendicular to the riverbank direction). This ensures that the gabions are stacked in a staggered manner and that the hollow concrete blocks form columns with a clear spacing of 1m. Steel pipe piles are driven into the outside of the gabions to serve as retaining walls for the ferry crossing. Attached Figure Description

[0021] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1-5 As shown, a combined permanent and temporary vehicle ferry device for road construction is provided. The device comprises multiple layers of gabions 1 arranged along the longitudinal axis of the ferry retaining wall. Each layer contains multiple gabions 1, with the number of gabions 1 in the upper layer being less than the number of gabions in the lower layer, so that the multiple layers of gabions are arranged in a stepped manner along the longitudinal axis to form a stepped gabion retaining wall. Each gabion is a structure with diamond-shaped mesh made of woven steel wire. Each gabion contains multiple partitions arranged along its length, which divide the space inside the gabion into multiple gabion unit grids. Each gabion unit grid is filled with 150-250mm boulders 2 and hollow concrete blocks 3. The boulders 3 and hollow concrete blocks 3 are arranged at intervals within the gabion unit, and the hollow concrete blocks along the river channel form spaced columns with a net distance of 1m.

[0023] The construction steps are as follows:

[0024] 1. The total length of the retaining wall along the ferry crossing is 15m, and gabions are installed along its longitudinal axis. The gabion retaining wall is stepped.

[0025] 2. The gabion unit size of this project is 3m×1m×0.5m, with a mesh spacing of 1m. The weaving material is diamond mesh made of steel wire with a diameter of φ2.7mm, and the binding steel wire is steel wire with a diameter of φ2.2mm. The steel wire is protected against corrosion by aluminum zinc coating and plastic coating. The filling material is 150~250mm stones and concrete hollow blocks, which are filled in the gabion unit mesh at intervals.

[0026] 3. Several layers of geogrid (1m vertical spacing) are laid horizontally on the inside of the gabion retaining wall, and the geogrid and gabion are tied tightly with wire. The several layers of geogrid are used to make reinforced soil; the reinforced soil is formed by backfilling and compacting.

[0027] 4. After the ferry retaining wall is completed, a 24cm thick double-layer steel mesh C30 concrete roadway slab is installed along the 16m length of the top layer of the gabion retaining wall in the direction of the access road. The steel mesh is made of 8mm diameter ribbed steel bars and the mesh size is 150×150mm. The thickness of the upper and lower concrete protective layers is 3cm respectively. After the concrete has initially set, it is roughened and grooved for anti-slip treatment.

[0028] To ensure the normal operation of ferry crossing facilities and supporting infrastructure during construction, maintenance and upkeep are equally important. Appropriate maintenance and upkeep plans should be developed, and the ferry crossing facilities should be inspected regularly to promptly identify and address any problems. Maintaining and upkeep of ferry crossing facilities not only extends their service life and ensures safety but also improves their efficiency and user comfort.
