Method for pipeline filling material construction using pipeline filling material construction device

Abstract

The invention provides a pipeline filling material construction device and method. A support plate is connected with a bearing plate through a limiting steel wire rope, the bearing plate is connected with one end of a locating steel wire rope, and the other end of the locating steel wire rope is fixed; a flexible plugging filler is arranged between the support plate and the bearing plate in a filling manner; the orifice section of a plugging steel tube is synchronously and manually filled with the flexible plugging filler, the filler is pushed into the tube step by step, and after filling ends and the filler is totally pushed into the orifice section of the tube for a certain distance, the locating steel wire rope is fixed on a steel wire rope fixing ring on the inner wall of the orifice section of the plugging steel tube; the locating steel wire rope is coiled in the orifice section of the plugging steel tube in order; a tube orifice of the plugging steel tube is connected with a water pipe connected with a water pump; the water pump is started to pressurize water, and pressure maintaining is performed for a period of time; located plugging construction of a filling material of a pipeline is realized through the steps. The defect that filling construction of hemp threads and SR fillers in the depths of the plugging steel tube cannot be realized with a conventional filling construction process due to limit of the long-distance and non-linear plugging steel tube is overcome.

Description

technical field [0001] The invention relates to the construction field of water conservancy and hydropower projects, in particular to a method for constructing pipeline filling materials by using a pipeline filling material construction device. Background technique [0002] For a dam project of a hydropower station, the reverse drainage layout and plugging structure diagram during the construction period issued according to the design, as shown in figure 2 As shown, before the reverse drainage pipe in front of the dam is blocked, 100 cm thick hemp silk and 100 cm thick SR filler should be stuffed into the depth to temporarily prevent the reverse seepage flow, so as to ensure the grouting and pre-treatment of the subsequent reverse drainage pipe plugging section. The construction quality of shrinkage mortar plugging. [0003] After considering the length of the exposed steel pipe of the reverse drainage pipe, the distance from the hemp silk and SR filler to the nozzle along ...

AI Technical Summary

Problems solved by technology

In this project, due to the limitation of long-distance and non-linear drainage steel pipes, the conventional and traditional construction techniques in the past cannot meet the construction of hemp silk and SR filler in the depth of the reverse drainage pipe designed in front of the dam in this project.
