Sand-stone separating and cleaning equipment suitable for muck recycling and construction method

Abstract

The invention provides sand-stone separating and cleaning equipment suitable for muck recycling and a construction method. The sand-stone separating and cleaning equipment suitable for muck recycling comprises a first collecting pool, a separating cylinder, a sand cleaning device, a vibrating table and a third collecting pool, wherein the first collecting pool is used for collecting stones separated from muck; the separating cylinder is arranged above the first collecting pool and is obliquely arranged along the axis direction; the separating cylinder rotates around the axial direction of the separating cylinder, so that stones in the muck slide into the first collecting pool under the action of gravity, and the separated sand-containing muck falls down from pores in the outer wall of the separating cylinder under the action of gravity; the second collecting pool is used for collecting the sand-containing muck falling down from the pores in the outer wall of the separating cylinder; the sand cleaning device is used for cleaning and filtering the collected sand-containing muck and separating out sand; the vibrating table is used for filtering moisture in the sand separated by the sand cleaning device; and the third collecting pool is arranged on one side of the vibrating table and is used for collecting the sand separated by the vibrating table. The sand-stone separating and cleaning equipment suitable for muck recycling and the construction method provided by the invention can effectively separate and clean sand and stones in shield excavation muck, realizes recycling of the muck, and is beneficial to resource saving and environmental protection.

Description

technical field [0001] The invention relates to the field of geotechnical engineering construction, in particular to a sand and gravel separation and cleaning device and a construction method suitable for recycling slag. Background technique [0002] At present, many cities are undergoing large-scale subway tunnel construction, and the shield method is one of the main methods for urban subway tunnel construction. A large amount of waste sludge will be generated during the shield tunneling process. Due to the environmental protection requirements of the city center and urban management and other factors, the transportation of sludge is often restricted. If the sludge is not disposed of in time, a large amount of sludge will accumulate at the excavation port, and the underground sludge cannot be discharged in time, which will affect the construction safety and delay the construction period. In addition, the disposal and transportation of waste sludge will consume a lot of cle...

Problems solved by technology

[0003] After searching the existing technical literature, it is found that the Chinese patent application number CN201920534194.1 proposes a sand and gravel separation and cleaning equipment, which feeds the material through the opening towards the top feeding hopper, which is easy to operate and occupies a small area , the feeding is smooth, the processing capacity is large, and the work efficiency and economic benefits are improved; the rotation of the sieve barrel and the spraying of the water spray pipe are used to wash the concrete, so that the concrete is separated during the turning process and is fully cleaned at the same time; The proportion of sand and gravel in the dregs changes rapidly according to the change of the excavation stratum. This patent mainly uses the spiral blade to separate the sand and gravel by scraping, and when the content of gravel is large, it is easy to cause the blade to be stuck or even damaged. less efficient

In addition, there is also the problem that the sand and gravel separated from the shield tunneling construction site cannot be collected effectively, which is inconvenient for the subsequent recycling of aggregates.
