Description

Technical Field

[0001] The present invention relates to the technical field of pipe jacking construction, and in particular to a soil pressure balance mud-water conversion system and method for pipe jacking construction. Background Art

[0002] Earth pressure balance pipe jacking construction is a pipeline burial construction technology with no excavation or minimal excavation. After the pipe jacking working well and receiving well are dug on the ground, the jacking force generated by the earth pressure balance pipe jacking equipment is used in the pipe jacking working well to overcome the friction between the pipeline and the surrounding soil, and the pipeline is pushed into the receiving well according to the designed slope to complete the pipeline laying, and the generated earthwork is transported away. The earthwork is composed of stones and soil blocks. The existing method of transporting earthwork is to mix the earthwork with water into mud and then transport it to a preset mud pool through a pipeline. Under different geological conditions, the stone content in the earthwork generated by the earth pressure balance pipe jacking equipment is inconsistent. When the stone content is high, the stones need to be further crushed before they can be transported through pipelines to avoid pipe jams. In this process, in order to ensure the degree of stone crushing, multiple high-power mixers are generally used to mix and crush the stones. Due to different underground geological conditions, earthwork with low stone content does not require high-power mixers to mix and crush the stones. If only high-power mixers are used, high energy consumption will occur. If only low-power mixers are used, the stones cannot be crushed, resulting in the degree of stone crushing in the earthwork not meeting the requirements, leading to pipe jams.

[0040] like Figure 5 As shown, the adjustment system 11 includes a sound collection module 111, a sound analysis module 112 and an adjustment module 113;

[0041] The sound collection module 111 is used to collect data from the sound collector a67, the sound collector b68 and the sound collector c69 respectively;

[0042] Specifically, the sound collection module 111 includes a collection unit a1111, a collection unit b1112 and a collection unit c1113.

The adjustment unit 1132 is used to adjust the power of the agitator a64, the agitator b65 and the agitator c66 according to the power adjustment amount. When the crushing degree of the stones in the cavity a611 reaches the requirement, the power calculation unit 1131 obtains the adjustment amount for shutting down the agitator b65 and the agitator c66, and calculates the adjustment amount for linearly reducing the power of the agitator a64. The adjustment unit 1132 shuts down the agitator b65 and the agitator c66. c66, and at the same time linearly reduce the power of the agitator a64. When the speed of the stone powder in the cavity a611 just reaches the requirement, the regulating unit 1132 maintains the power of the agitator a64. When the degree of crushing of the stone in the cavity a611 is lower than the requirement and the degree of crushing of the stone in the cavity b612 reaches the requirement, the power calculating unit 1131 obtains the adjustment amount for shutting down the agitator c66, and at the same time calculates the adjustment amount for linearly reducing the power of the agitators a64 and b65. The regulating unit 1132 shuts down the agitator c66 and linearly reduces the power of the agitators a64 and b65. When the speed of the stone powder in the cavity b612 just reaches the requirement, the regulating unit 1132 maintains the power of the agitators a64 and b65. 5, the power calculation unit 1131 calculates the adjustment amount of linear power reduction of agitators a64, b65 and c66 when the degree of stone crushing in cavity a611 and cavity b612 is lower than the requirement and the degree of stone crushing in cavity c613 meets the requirement, and the adjustment unit 1132 linearly reduces the power of agitators a64, b65 and c66. When the powder speed of the stone in cavity c613 just meets the requirement, the adjustment unit 1132 maintains the power of agitators a64, b65 and c66. The power calculation unit 1131 calculates the adjustment amount of linear power reduction of agitators a64, b65 and c66 when the degree of stone crushing in cavity c613 is lower than the requirement. The adjustment amount of power is linearly increased, and the regulating unit 1132 linearly increases the power of the agitator a64, the agitator b65 and the agitator c66. When the powder speed of the stones in the cavity c613 just reaches the requirement, the regulating unit 1132 maintains the power of the agitator a64, the agitator b65 and the agitator c66. In the above example, under different geological conditions, when the proportion of soil blocks in the earthwork is relatively high and when the proportion of stones in the earthwork is relatively high, the power of the agitator a64, the agitator b65 and the agitator c66 is adjusted according to the size and quantity of the stones and soil blocks, and the degree of crushing of the output stones is maintained in compliance with the requirements under the lowest power condition, so as to achieve the effect that the degree of crushing of the stones after mixing and crushing meets the requirements and the energy consumption is low.

[0047] The present invention forms a three-stage mixing structure by adopting agitator a64, agitator b65 and agitator c66. By detecting cavity a611, cavity b612 and cavity c613, the power of agitator a64, agitator b65 and agitator c66 is automatically adjusted according to the stone content in the earthwork, so that the crushing degree of the stones after mixing and crushing meets the requirements and the energy consumption is low.
