A deep buried pipe machine

Abstract

A deep-buried pipe machine includes a rear suspension frame, a power distributor, an excavation pipe-laying mechanism, a hydraulic lifting frame, a pipeline conveying mechanism, a high-pressure water pump, and a water tank. The power input shaft of the power distributor is connected with the power source, its driving sprocket is connected with the tunneling pipe-laying mechanism through a chain, and the horizontal output shaft is connected with the high-pressure water pump; the tunneling pipe-laying mechanism is installed in the hydraulic lifting frame through the limit guide wheel and the lifting guide rail , the hoisting wire rope is connected to the winch shaft of the hydraulic lifting frame, and the high-pressure water pipe joint is connected to the high-pressure water pump pipe; the hydraulic motor of the hydraulic lifting frame is driven by the hydraulic output of the vehicle; It is connected with the high-pressure water pipe joint pipe of the water tank and the excavation pipe-laying mechanism. The invention utilizes sandy soil fluidization combined with the method of excavation machinery stripping to realize large-depth pipe laying in sandy soil layer. bury.

Description

technical field [0001] The invention relates to pipeline laying equipment, in particular to a large-depth pipe-burying machine used for reinforcing dredging and filling sandy soil. Background technique [0002] In land reclamation projects, drainage is very important in the process of reclamation foundation reinforcement. In the prior art, the vertical drainage system Ruler If the drainage board is used, the horizontal drainage system Ruler It should be cushion sand layer and blind ditch. Using the existing method to reinforce the dredger filling mainly on the sandy soil layer has a long construction period, high cost and low drainage efficiency. In order to achieve rapid and massive drainage of the dredged sandy soil layer, the permeable pipe can be buried deep in the sandy soil layer, and the permeable pipe is connected to a water pump, and the water seepage in the pipe can be pumped out by the pump to increase the drainage speed and speed up the drainage consolidation o...

AI Technical Summary

Problems solved by technology

[0004] The trenching machine in the scheme of trenching first and then laying is a chain trencher, which cannot be applied to deep pipe buried in water-containing sandy soil. Its disadvantages are as follows:

[0005] 1. The principle of chain ditching technology cannot be applied in this working condition. The chain ditching machine cannot realize ditching at a depth of 4m to 6m, because the principle of the ditching machine is to break the soil and lift it out of the ditch. Excavated more soil

Large-depth buried pipes lift more soil, consume more power, have complex transmission, and lower reliability

[0006] 2. The sandy soil with high water content has low viscosity, and it is impossible to dig out the formed ditches. The dug out ditch will be quickly buried by the sandy soil layer, so the process of digging the ditch first and then laying the pipe cannot be realized.

[0008] 1. The chain-type structure mechanism is relatively complex, and the transverse dimension of the mechanism is long. It needs to be lifted when turning, which will cause the inability to lay continuously at the turning of the pipeline, which will easily cause inconsistency of the permeable pipeline and uneven settlement of the foundation.

[0009] 2. The tool chain of chain ditching is a closed chain. The chain tool moves upward in the direction of equipment advancement to be the tight side, and the other side is the loose side. After the sand returns, the loose side is buried in the sand, and the loose side will be stressed. If it is tight, it will cause detachment, and it will generate lifting force, which is not conducive to ensuring uniform depth of buried pipe

[0010] 3. In the existing technology, the excavation depth of chain trenching does not exceed 2m. For chain trenching with a depth of 4m to 6m, its structure is complicated and its reliability will be greatly reduced.

And the sandy soil layer will fall back quickly, the power consumption will increase greatly, the power requirement for the power machine will increase, the weight of the whole machine will increase, and the construction equipment may sink during the laying process
