[0022] The shorter the distance between the mud pool 1 and the sand filter 2, the faster the mud flow rate, and the higher the flow rate can be achieved. According to the on-site construction environment, the high-pressure hose 3 is connected after the position setting of the mud pool 1 and the sand filter 2 is completed. Under normal circumstances, the high-pressure hose 3 is directly connected to the slurry inlet pipe 9 of the sand filter 2 through the mud pump 4. The high-pressure hose 3 is bound to be unable to be straightened, and it falls freely, and the spacing cannot be guaranteed. The high-pressure hose 3 corresponding to the mud pump 4 of the present application is straightened as much as possible and extended from the connecting port 8, and then connected to the slurry inlet pipe 9 through the straightened connecting pipe 10, so as to ensure the shortest spacing as possible, achieve a high flow rate, and thus improve construction efficiency.
