Natural gas pipeline soft soil foundation settlement control device
The invention relates to a settlement control device for a soft soil foundation of an external transportation natural gas pipeline. The settlement control device is mainly composed of an LNG storage tank, an infusion pump, a liquid inlet pipe, a liquid return pipe, a vaporizer, a communicating pipe, a signal monitoring terminal and a monitoring computer. And the low-temperature LNG liquid passes through the liquid inlet pipe and the liquid return pipe and then returns to the vaporizer. A plurality of communicating pipes are arranged between the liquid inlet pipe and the liquid return pipe, the liquid inlet pipe, the liquid return pipe and the liquid inlet pipe are laid below a natural gas output pipeline, the cooling capacity can be adjusted by inputting the cooling capacity into a surrounding soft soil foundation, freezing the stratum shape and monitoring the soil temperature in real time, and therefore effective control over stratum settlement is achieved. Soft soil foundation settlement control is carried out through the LNG cooling capacity, extra cooling capacity is not consumed, and wide application prospects are achieved.
本发明涉及一种外输天然气管道软土地基沉降控制装置，主要由LNG储罐、输液泵、进液管、回液管、汽化器、连通管、信号监控端子、监控计算机组成。低温LNG液体通过进液管、回液管后返回进入汽化器。进液管和回液管之间设有若干连通管，三者敷设于天然气外输管道下方，通过向周围软土地基输入冷量，对地层形进行冻结，通过实时监测土壤温度，可以调节冷量大小，从而实现地层沉降的有效控制。本发明利用LNG自身冷量进行软土地基沉降控制，不消耗额外冷量，具有广阔的应用前景。
