FLOATING MAT CLEANING SYSTEM FOR RUBBISH AT WATER INTAKE OF LARGE WATER SUPPLY SOURCE PROJECT AND CONSTRUCTION METHOD THEREFOR

摘要

A floating mat clearing system for rubbish at a water intake of a large water supply source project and a construction method therefor. The system comprises: guide ray assemblies (1) fixed to side piers (101) and/or a middle pier (102) disposed at the water intake, and perpendicular to the water surface; a floating mat (2) which is in sliding fit with the guide rail assemblies (1) and floats on the water surface; a submersible pump (3) which is fixedly assembled on the floating mat (2) and is provided underwater; and a water spraying assembly (4) which is installed on the floating mat (2) and communicated with the submersible pump (3). The submersible pump (3) extracts water and sprays the water to a direction outside the water intake by means of the water spraying assembly (4), so that the rubbish accumulated at the water intake is pushed away by the sprayed water and then is taken away by the water flow. The problem that manual clearing of rubbish at a water intake is tedious is solved, and the purpose of rapidly and efficiently clearing the rubbish at the water intake is achieved.
