Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a slag discharging device for a rectangular pipe jacking machine. Background Art

[0002] Pipe jacking is a trenchless construction method, a pipeline burial construction technology with no excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunnel boring machine from the working pit through the soil layer and lift it into the receiving pit.

[0003] Pipe jacking construction is an underground pipeline construction method developed after shield construction. It does not require excavation of the surface layer and can pass through roads, railways, rivers, ground buildings, underground structures and various underground pipelines.

[0004] The principle of pipe jacking machine is similar to that of shield machine, and it is divided into slurry balance pipe jacking machine and earth pressure balance pipe jacking machine. Slurry balance pipe jacking machine uses mud circulation to discharge slag; earth pressure balance pipe jacking machine uses screw machine + slag bucket to discharge slag.

[0005] Traditional earth pressure balance pipe jacking machines, because the pipe jacking construction mileage is relatively short, due to the size of the working pit, the horizontal transportation of the muck generally adopts a customized small muck bucket and a winch for combined transportation. However, due to space constraints, the volume of the muck bucket is 5m 3 , the excavation of one ring requires the muck bucket to go in and out 10 times. Excavation cannot be carried out during the process of transporting and unloading a single muck bucket, and the transportation time accounts for 50% of the total time for excavation and assembly of one ring, so the slag discharge speed of the pipe jacking machine is particularly slow and the efficiency is particularly low.

In this way, the slag holding structure can be quickly moved to the slag holding position to ensure the construction speed.

[0024] According to one solution of the utility model, the slag collecting structure includes: a slag collecting car, which is detachably hoisted on an electric hoist; the slag collecting car includes a slag collecting bucket and a mobile structure arranged at the bottom of the slag collecting bucket.
