Embodiment

[0028] Example, a construction method of a mud storage tank for dredging and dredging, such as figure 1 with figure 2 As shown, the construction method includes the following steps:

[0029] S1: Carry out the excavation of the mud storage tank according to the preset size, and perform the base leveling treatment on the inner wall of the dug mud storage tank;

[0030] Optionally, in step S1, the base surface leveling treatment includes laying an 8cm to 15cm thick sand and gravel cushion on the bottom of the mud storage tank for leveling, while making the sidewall surface of the mud storage tank at a vertical depth Keep a flat surface within 2.5cm, that is, no sharp objects within 2.5cm of the vertical depth of the mud storage tank, such as prismatic objects or pyramid-shaped objects, or cylindrical or polygonal objects, etc., preferably sandstone The thickness of the cushion can be 10cm;

[0031] S2, laying a geotechnical anti-seepage membrane, extending along the bottom of the mud...

Abstract

The invention belongs to the technical field of anti-seepage engineering, and particularly relates to a construction method of a sludge storage tank for dredging. The construction method of the sludgestorage tank for the dredging comprises the following steps that the sludge storage tank is excavated according to a preset size, and the base surface leveling treatment is conducted on the inner wall of the excavated sludge storage tank; a geotechnical anti-seepage film is laid, extends along the bottom of the sludge storage tank to the tank edge of the sludge storage tank; film pressing and shaping is performed on the laid geotechnical anti-seepage film; experimental welding is performed on a taken soil sampler anti-seepage film sample; productive welding is performed on the adjacent geotechnical anti-seepage film; and detecting and repairing are performed on the welded part of the welded geotechnical anti-seepage film; and concrete pouring is performed on the welded geotechnical anti-seepage film, and plain soil is laid on the poured concrete. According to the construction method of the sludge storage tank for the dredging, the geotechnical anti-seepage film is laid on the base surface of the sludge storage tank, the layer of concrete is poured on the geotechnical anti-seepage film, and then the plain soil is laid, the operation is convenient and simple, the construction periodis short, the cost is low, and the economic benefit is high.

Description

Technical field [0001] The invention belongs to the technical field of anti-seepage engineering, and specifically relates to a construction method of a mud storage tank for dredging and dredging. Background technique [0002] At present, during river dredging construction, the silt storage tank is mainly used for temporary storage of pumped silt. Due to the poor water quality of the river, the ammonia nitrogen and total phosphorus exceed the standard, the concentration of total nitrogen and total phosphorus in the bottom sludge is high, the pollution is heavy, and the heavy metals lead and zinc are high, so strict requirements on the anti-seepage of the mud storage tank. In normal construction, the bottom of the mud storage tank is generally made of reinforced concrete structure or brick-concrete structure. This type of construction has a high cost and a long construction period. Additional expenses will be incurred when abolished later. In addition, because the walls of the mud ...
