The invention relates to a module concrete limit basic structure applied in the pipe-sink tunnel project, which mainly comprises the steel plates on the basic top surface, and the module bags on the side and bottom surfaces. It is characterized in that: it also comprises concrete irrigating hole, checking holes, module bag anti-turn device, and limit device. Wherein, the limit device is welded on two sides of said top steel plates; the module bag is made by high-strength cloth and fixed on the top steel plate via bolt; the whole integrated elements can control the plane position and height of top steel plates via special device to fill underwater concrete in the module bag to form base, while the module bags of basic bottom can naturally adhere with the dig surface; when the base has reached preset strength, the pipe is directly laid on the base to fix the pipe via limit device. The invention has the advantage that the pipe is directly laid on the basic top surface to avoid the process of sticking the pipe bottom with the basic top surface and the limit device can improve its stability.
