Description

Technical Field

[0001] The utility model relates to the technical field of sand suction, in particular to a sand suction pump used for deep foundation pit free-fall drainage excavation construction. Background Art

[0002] In the traditional deep foundation pit construction process, in order to prevent the slope from becoming unstable and ensure the construction safety, a sand suction pump is often used to carry out water excavation in the deep foundation pit. That is, the sand suction pump pipe head is equipped with a high-pressure water gun. During the construction, the mud and sand at the bottom of the foundation pit are dispersed by the high-pressure water gun to form a mud-sand mixture. At the same time, the dispersed mud-sand mixture is sucked out by the sand suction pump, and finally blown and filled into the designated mud receiving area through the mud discharge pipeline to complete the deep foundation pit drainage-free excavation operation. However, when the existing sand suction pump sucks out the dispersed mud-sand mixture, there is no device for pre-treating larger particles of mud and sand. The larger particles of mud and sand may cause the sand suction pump to be blocked. At the same time, the large amount of mud and sand sucked in at one time may cause the pipeline to be blocked, thereby affecting work efficiency. Utility Model Content
