Further, the utility model pvc pipe road is laid anti-skidding with circular plug connecting place and is protected piece.
Further, to protect the length that piece stretches into pvc pipe road be 5cm to the utility model anti-skidding.
Further, sealing mat is arranged in the junction of the utility model pvc pipe road and stainless steel substrates.
Further, the center of circle of the utility model pvc pipe road, circular plug is on same level line.
Further, it is 30cm that the utility model pvc pipe road stretches into soil length, and the internal diameter in pvc pipe road is 10cm, and the thickness of pipe wall in pvc pipe road is 2cm.
Further, the internal diameter of the circular plug of the utility model is 15cm.
Further, the length of the utility model reinforcing bar is 40cm, stretches out circular plug portion and bends to circular.
Further, the internal diameter of the utility model stainless steel substrates is 10cm.
The utility model compared with prior art, there is following beneficial effect: the one, the utility model soaks ditch by irrigation canal and row and unites two into one, peasant needn't be by the method dewatering of the provisional drainage channel of annual excavation, has reduced the input of manpower, financial resources, material resources aspect; The 2nd, the utility model soaks irrigation canal and row after ditch merges, can save the row of laying in field and soak the shared land area of ditch; The 3rd, in the time of needs dewatering, only circle plug need to be pulled out, easy to operate simple; The 4th, soak ditch than existing row, the utility model adopts concrete-lined canal, after channel sclerosis, needn't consider to get rid of the caused stability of slope problem of underground water.
