High-concentration bag filling process method and device

Abstract

The invention discloses a high-concentration bag filling process method and a device. The device comprises a slurry blending pool, wherein a storage pool and a water supply pool are arranged beside the slurry blending pool; high-dryness slurry is stored inside the storage pool; a conveyer is arranged between the storage pool and the slurry blending pool; the conveyer is fed with slurry through an excavator; the water supply pool is connected with the slurry blending pool through a submersible pump and a pipeline; trusses are arranged at the upper part of the slurry blending pool; stirrers and densimeters are fixedly arranged on the trusses; a sludge pump is arranged in a bottom corner position of the slurry blending pool; the sludge pump communicates a multi-way tube outside the slurry blending pool through a conveying tube. The high-concentration bag filling process method of the device comprises a step of preparing continuous stable high-concentration sludge in a mechanical stirring mode. By adopting the high-concentration bag filling process method and the device, the purpose of preparing sludge and filling the sludge into bags simultaneously is achieved, the requirement of continuous production can be met, the density of conveyed sludge is greater than 1.7t/m<3>, and the problem that in the prior art the fine granular material bag filling efficiency is low can be greatly solved. Meanwhile, due to electric control, the automatic level of a system can be improved, the artificial operation intensity can be effectively alleviated, and the method and the device have great application and popularization values.

Description

technical field [0001] The invention relates to a bag-filling construction method and device for bagged soil in embankment land reclamation engineering. Background technique [0002] At present, bagged sand is widely used in embankment construction projects. The basic construction technology is: use mud ponds or mud barges as sand storage tanks, and liquefy the mud and sand around the mud pumps in the sand storage tanks by high-pressure flushing. The centrifugal mud pump transports the liquefied mortar to the filling bag. However, with the increasing shortage of sand sources, many projects are faced with the dilemma of no sand available or long-distance purchase of sand, so they have to use nearby materials, and use fine-grained materials represented by silt as bag filling materials to solve construction problems. [0003] In the process of filling bags with fine-grained soil, the traditional construction technology has disadvantages such as low transport concentration, une...

AI Technical Summary

Problems solved by technology

To solve the problem of the low concentration of fine-grained soil conveyed by the traditional centrifugal bag filling process, high-pressure flushing does not mix the soil in the mud storage tank evenly, the drainage cycle is long after bag filling, it is difficult to consolidate, and repeated bag filling is required to achieve The problem of low bag filling efficiency to meet the needs of embankment
