Problems solved by technology

[0002] Most of the large and medium-sized hydropower station’s drains or water inlets, the section from the hole to the maintenance door slot has been subjected to long-term erosion and erosion by water flow since it was put into operation, but it cannot be repaired, resulting in the steel lining of the bottom plate, the concrete of the bottom plate and the concrete side wall. The degree of damage caused by the flushing groove (pocket) on the steel lining of the bottom plate causes water leakage at the bottom

Abstract

The present invention relates to the repair of watercourse and gate recess for hydraulic power station, and is especially one method of utilizing float gate for water shut-off to create dry land condition for haul and repair. It has the features of being convenient, complete and low in cost. The method is that float gate is set in the entrance of sluiceway to form dry land construction condition inside the sluiceway. The float gate shut off water in the deep water head of 60-100 m, has size of (5-15)x(8-20) m corresponding to the entrance size to be shut off.

Description

Technical field: [0001] The invention relates to a method for repairing waterways and gate slots of a hydropower station, in particular to a method for repairing and restoring the waterways and gate slots to the original state by using floating body maintenance gates to seal holes and block water to create dry land conditions. Background technique: [0002] Most of the large and medium-sized hydropower station’s drains or water inlets, the section from the hole to the maintenance door slot has been subjected to long-term erosion and erosion by water flow since it was put into operation, but it cannot be repaired, resulting in the steel lining of the bottom plate, the concrete of the bottom plate and the concrete side wall. The degree of damage caused by the flushing groove (pocket) on the steel lining of the bottom plate causes water leakage at the bottom of the inspection door, water piercing through holes in the steel lining of the bottom plate, exposed concrete aggregates ...
