Embodiment Construction

[0032] refer to Figure 1 to Figure 2 Further explain the construction method of preparing engineering bags from marine silt solidification. A construction method for solidifying marine silt to prepare engineering bags, such as figure 1 shown, including the following steps:

[0033] S1. Prepare the curing agent slurry, put the curing agent into the curing agent storage tank 1 and stir temporarily; wherein, the curing agent is equipped with a solid curing agent and a liquid curing agent, and the curing agent storage tank 1 stores the solid curing agent and the curing agent The discharge end of the storage tank 1 is sent to the metering scale 10 for metering through the screw conveyor 9, so as to be added quantitatively. The liquid curing agent is stored and supplied through the liquid curing agent adding system 12. The liquid curing agent adding system 12 is composed of an infusion pipe and a flow rate Valve supply, quantitative addition through the flow valve;

[0034] S2. ...

Abstract

The invention discloses a construction method for preparing an engineering bag by curing marine sludge, and relates to the technical field of sludge treatment, and the key point of the technical scheme is that the construction method comprises the following steps: S1, preparing curing agent slurry; S2, taking the marine mud flat sludge and putting the marine mud flat sludge into a sludge pretreatment box for stirring; S3, conveying a curing agent and the pretreated sludge into a flow-state solidified soil stirring tank to be stirred; S4, introducing a proper amount of water into the flow-state solidified soil stirring tank for mixing and stirring; S5, conveying the curing agent and the slurry in the flow-state solidified soil stirring tank into a flow-state solidified soil conveying tank for secondary stirring; S6, spreading an engineering bag, and connecting the flow-state solidified soil conveying tank with a filling opening of the engineering bag through a mud conveying pipeline; and S7, using the slurry pump for conveying the flow-state solidified soil into the engineering bag through the slurry conveying pipeline, and producing the engineering bag. According to the method, the engineering bag can be filled with the flow-state solidified soil rapidly prepared from the marine sludge, the cost is saved, the sludge and water resources are reasonably utilized, and the effect of saving resources is achieved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a construction method for solidifying marine sludge to prepare engineering bags. Background technique [0002] The geotechnical bag is a large-area continuous bag-shaped material made of upper and lower layers of geotextiles. The bag is filled with concrete or cement mortar, which forms an integral concrete slab after solidification, which is suitable for slope protection. At present, the material in the geotechnical bag is mainly concrete or cement mortar, but the cost of cement mortar and concrete is high, resulting in high cost of use, and the production process requires a large amount of water to be mixed with concrete or cement to make it. More, resulting in waste. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a construction method for preparing engineering bags by solidifying ma...
