Description
Technical Field
The invention belongs to the field of building construction, and particularly relates to a transportation method of a large pipeline in comprehensive pipe gallery construction.
Background
In urban construction, the corridor pipeline of utility tunnel is more, and its cross-section divides into a plurality of cabins, and wherein, large-scale pipelines such as urban water supply, drainage arrange in the cabin alone. In utility tunnel construction, there are two problems in the transportation of large pipeline: 1) the cabin space is narrow, and large-scale mechanical equipment cannot be accessed; 2) the utility model discloses a large-scale pipeline, including cabin, utility tunnel, escape canal, cabin, and the utility tunnel belongs to the underground space, has the infiltration hidden danger, consequently can set up the escape canal in the cabin, because the space of cabin itself is narrow and small, therefore the ground at escape canal place must be utilized, just can guarantee the normal transportation of large-scale pipeline, and present construction method is to pack the escape canal, makes ground keep the level, but this method consumes labour and time consuming material, and the construction is complicated.
Disclosure of Invention
The invention aims to provide a method for transporting a large pipeline in comprehensive pipe gallery construction, which makes up for height difference generated by a drainage ditch, avoids large shaking, and has high working efficiency and low cost.
The technical scheme adopted by the invention is as follows:
a transportation method of large pipelines in comprehensive pipe gallery construction includes that before transportation, a transportation vehicle is manufactured, wherein the front end and the rear end of a vehicle frame are provided with hanging points, two sides of the top of the vehicle frame are provided with limiting blocks, two sides of the bottom of the vehicle frame are provided with wheels, the wheels on one side are small wheels and are supported on the bottom surface of a cabin, and the wheels on the other side are large wheels and are supported on the bottom surface of a drainage ditch, so that the top of the vehicle frame is enabled to be flush; during transportation, the winches are arranged at the front and rear parts of the transport vehicle, steel wire ropes of the front and rear winches are respectively connected with the outer hanging points at the front end and the rear end of the frame, the large-sized pipeline is hung between the limiting blocks on the two sides of the top of the frame, the transport vehicle is pulled to move forwards and backwards by the winches, and the large-sized pipeline is hung on the pipeline buttress after the transport vehicle reaches an appointed place.
Furthermore, one side of the limiting block close to the large-sized pipeline is an arc-shaped surface or an inclined surface.
Furthermore, the outer hanging point is positioned in the center of the bottom of the front end and the rear end of the frame.
Further, the frame comprises a square frame and a diagonal brace.
Furthermore, the frame is formed by splicing channel steel.
The invention has the beneficial effects that:
according to the method, the height difference generated by the drainage ditch is made up by utilizing the height difference of the large wheels and the small wheels, the top of the frame is ensured to be level, meanwhile, the transport vehicle is pulled to move in the front and back direction by utilizing the winch, and large shaking cannot occur due to bidirectional stress, so that the transport quality is ensured; the method has the advantages of small equipment size, convenient rolling and simple operation steps, thereby having high working efficiency; the transport vehicle in the method is simple to manufacture, can be repeatedly recycled and is low in cost.

Detailed Description
The invention is further described below with reference to the figures and examples.
As shown in fig. 1 to 3, a transportation method of a large pipeline in comprehensive pipe gallery construction includes that before transportation, a transportation vehicle is manufactured, wherein the front end and the rear end of a vehicle frame 3 are provided with outer hanging points 5, two sides of the top are provided with limiting blocks 2, two sides of the bottom are provided with wheels, the wheels on one side are small wheels 6 and are supported on the bottom surface of a cabin, the wheels on the other side are large wheels 4 and are supported on the bottom surface of a drainage ditch, and the top of the vehicle frame 3 is ensured to be flush; during transportation, winches are arranged at the front and rear parts of the transport vehicle, steel wire ropes of the front and rear winches are respectively connected with the outer hanging points 5 at the front end and the rear end of the frame 3, the large-sized pipeline 1 is hung between the limiting blocks 2 on the two sides of the top of the frame 3, the transport vehicle is pulled to move forwards and backwards by the winches, and the large-sized pipeline 1 is hung on the pipeline buttress 8 after the transport vehicle reaches a specified place. According to the method, the height difference generated by the drainage ditch is made up by utilizing the height difference between the large wheels 4 and the small wheels 6, the top of the frame 3 is ensured to be level, meanwhile, the transport vehicle is pulled to move in the front and back direction by utilizing the winch, and due to bidirectional stress, large shaking cannot occur, and the transport quality is ensured; the method has the advantages of small equipment size, convenient rolling and simple operation steps, thereby having high working efficiency; the transport vehicle in the method is simple to manufacture, can be repeatedly recycled and is low in cost.
