Problems solved by technology

However, the application of electroosmosis is also plagued by problems such as anode corrosion and excessive interface resistance. The reinforcement of soft clay foundation by electroosmosis alone has uneven soil reinforcement and high energy consumption, which limits engineering applications.

Embodiment Construction

[0024] Refer to attached figure 1 A ground treatment method and a ground treatment device embodiment of filling a curing agent in the electroosmotic process of the present invention will be further described in detail.

[0025] A ground treatment method for filling a curing agent in an electroosmosis process, comprising the following steps:

[0026] (1) Transport the prepared ferric chloride flocculant into the blow-fill pipeline, then blow the flocculation blow-fill into the foundation, let it stand for a period of time, and then level the foundation, in order to better flocculate The dredging fill is blown into the foundation, the ferric chloride flocculant can be sucked into the pipeline by the mud pump, the flocculant and the soil are rotated and stirred by the blade fan in the pipeline, and then transported and blown into the foundation.

[0027] (2), on the foundation that needs to be treated, lay a layer of woven cloth 1, and mark the woven cloth 1, and insert the nega...

Abstract

The invention discloses a foundation treatment apparatus and method with hardener filling in electro-osmosis process. The method herein is characterized by comprising delivering a prepared iron chloride flocculant into a blow-filling pipeline so that flocculated backfill is blown into a foundation, allowing to stand for a period of time, leveling a foundation, laying a layer of woven cloth, marking the woven cloth, and inserting negative and positive electrodes and a plastic drain plate in respectively marking positions, wherein the upper end of the plastic drain plate is connected to an auxiliary wire hose via a single-hand plate connector, and the secondary wire hose has penetrating depth of 1 m; after installation, powering off is started, a jet pump is started, and a hardener is injected from a large depth to a small depth through a grouting pipe when cracking occurs in late period of earth; earth and interfacial resistance can be decreased, electro-osmosis is allowed to play, andearth strengths can be more efficiently improved.

Description

technical field [0001] The invention relates to the field of foundation treatment, more specifically, it relates to a foundation treatment method and a foundation treatment device for filling a curing agent in an electroosmotic process. Background technique [0002] With the rapid development of construction in coastal areas of our country, the supply of land resources is becoming more and more tense, and land-making projects are constantly emerging. However, soft soil usually has the characteristics of fine particles, high plasticity, and low permeability. When the conventional drainage consolidation method is used to reinforce this kind of foundation, the initial effect is relatively obvious, but the later reinforcement effect is obviously reduced. If the value is small, the reinforcement effect is not very ideal. The electroosmosis method has the advantages of fast reinforcement speed, good reinforcement effect on fine particles and low permeability soil, and has the eff...
