Slurry Transport System (STS)<\/h3>\n

STS is a muck transport system for tunnel construction that uses a slurry-type Tunnel Boring Machine (TBM). The system circulates the slurry into the TBM\u2019s chamber to stabilize its face against earth and water pressure from the ground. The slurry then mixes with excavated muck, and then gets pumped out of the shaft for treatment.<\/p>\n

STS Flow<\/h4>\n

\"\"<\/p>\n

[1] Slurry Feed Pump<\/span><\/p>\n

P1 Pump, powered by a variable speed motor, controls the tunnel-face pressure. An additional PM pump may be installed to assist maintaining the tunnel-face pressure while excavation is halted. <\/p>\n

[2] Slurry Discharge Pump<\/span><\/p>\n

P2 pump sends out a mixture of muck and slurry. Additional PE, PX, and Pn pumps may be installed to assist controlling the discharge flow rate. <\/p>\n

[3] Circulation Pump<\/span><\/p>\n

P0 pump maintains the flow of the circulation system. Flowmeters along the circulation system allow precise control of the pump\u2019s revolutions per minute (RPM).<\/p>\n

[4] Gravel Processor<\/span><\/p>\n

Bigger gravel within the fluid can clog the pipelines and pumps. The gravel crusher will process this gravel into a smaller size to minimize this concern. <\/p>\n

[5] Valve Set<\/span><\/p>\n

The automatic valve unit inside the tunnel will operate bypaths and circuits, while a shaft-bottom valve set is used for adding pipes and assisting bypaths at the shaft. Both valve sets operate by compressed air.<\/p>\n

[6] Pipeline Extension Device<\/span><\/p>\n

A 3-way rotary valve stops the slurry flow during the pipeline extension to prevent slurry leakage. The hose-reel unit is also used to allow continuous circulation of slurry while an excavation is in progress.<\/p>\n

Sample Design (Subsequent Car)<\/h4>\n

We design and manufacture modules as well!<\/p>\n

• We design and manufacture frames, equipment, and an installment plan based on the rental machine\u2019s usage.<\/p>\n

• Total support on provisional facilities with our machine.<\/p>\n

\"\"<\/p>\n

Slurry Pump<\/h2>\n

•Abrasion resistant<\/p>\n

•Improved discharge\/power efficiency<\/p>\n

\"\"<\/p>\n

3-way Rotary Valve Set<\/h2>\n

• Allows leak-less extension of pipes for slurry type shield tunneling.<\/p>\n

• Will design as either a self-propelled or on wheels, depending on customer\u2019s request.<\/p>\n

\"\"<\/p>\n

System Abstract<\/h3>\n

During pipeline extension, the three-way valve will block the slurry\u2019s flow from the tunnel\u2019s face by switching the main outflow line to a plug line. The submerged pump in the water tank will send the plug (the pig) towards the shaft-side of the line, thus blocking the slurry from the face and assisting the extension of the pipeline. The pump is equipped with magnetic sensors to detect the plug\u2019s passing and arriving point, and can automatically send and return the plug. <\/p>\n

*This equipment must be used with a shaft-bottom valve set.<\/p>\n

*The water used for sending the plug must be processed by vacuum equipment, or disposed as wastewater.<\/p>\n
