Problems solved by technology

The traditional solution is to dig out the silt and bury it nearby. Although this can solve the problem of silt deposition, the silt also contains some harmful components such as toxic chemicals and pathogenic organisms. Direct burying will not only occupy a lot of cultivated land, but also polluted environment

Embodiment 1

[0022] Silt Solidification Project of Langqi Hongguang Lake Park

[0023] This project is located in Langqi Town, Fuzhou City, with a total solidified volume of 260,000 cubic meters. The construction areas for silt solidification are as follows:

[0024] (1) Solidification of lakeside slope; (2) Solidification of retaining wall and revetment;

[0025] (3) The solidification of the foundation of the filling area, including the solidification of the parking lot, paved square, and the foundation of the site;

[0026] (4) The roadbed of the park road is solidified.

[0027] Construction steps:

[0028] (1) Before construction, clean the surface of the site, remove debris on the surface of the site, and level the construction area;

[0029] (2) Sludge sampling, detection and analysis: Sampling of sludge, analysis of water content, particles and mineral composition of sludge, obtaining analysis data of sludge, and preparing sludge curing agent according to the obtained data; said sludge curing...

[0048] Soft foundation curing project of container stacking area in a port in Shenzhen

[0049] This project is located in a port in Shenzhen, and its port container area is backfilled with dredged silt. To be backfilled to the design elevation, use shallow foundation curing treatment. Its curing area is 200,000m 2 , Its solidified volume is 600,000 cubic meters. The object of solidification is highly compressible sludge. The technical indicators of silt are shown in the following table:

[0050]

[0051] Construction steps:

[0052] (1) Before construction, remove all the accumulated water in ponds and ditches, and excavate silt with an organic content of more than 6%;

[0053] (2) Sludge sampling, detection and analysis: Sampling of sludge, analysis of water content, particles and mineral composition of sludge, obtaining analysis data of sludge, and preparing sludge curing agent according to the obtained data; said sludge curing agent , In parts by weight, the raw material compo...

[0061] Dongdi Road (Haixu Road-Haiyue Road) Road Project in Tianjin Sino-Singapore Eco-city

[0062] The Dongdi Road of this project is located in Tianjin Sino-Singapore Eco-city, the original Tianjin Binhai Tourist Area. The planned functional positioning is mainly landscape and tourism, supplemented by transportation. The site along Dongdi Road is a land reclamation area for reclamation from the sea, and no vacuum reservation has been made. The maximum thickness of the landfill is 5m, and the filling period is 2 years. At the same time, there is about 6m of shallow marine sediment under the land. The above-mentioned soil layer has a large natural void ratio, a high natural water content, a large compressibility, and all are flow-plastic, and the foundation bearing capacity is low, which is a typical soft soil. Not only is it difficult for road construction machinery to enter the site, but also the settlement after construction is relatively large.

Abstract

The invention discloses a silt solidification soil construction technology which comprises the steps of surface cleaning drainage, silt sampling, detection analysis, excavation stacking, stirring and mixing, filling and grinding and stabilized soil maintenance. Through solidification soil in-situ solidification, silt and a curing agent are stirred and mixed to form silt solidification soil, and the curing agent is prepared through expanded graphite, activated carbon, cement, quick lime, gypsum, lignocelluloses, coal ash, granulated blast-furnace slag powder, coal gangue, caustic dross, hydroxypropyl methyl celluloses, furfural residues, medical stone and smectite clay. By means of the silt solidification soil construction technology, original flowing high-water-content low-strength high-compressibility silt is converted into high-compressive-strength excellent-entire-board-performance, good-durability and environment-friendly solidification soil, and the requirement of shallow ground earthwork materials for roads, storage yards, ports, reclamation projects, afforesting and the like can be met.

Description

Technical field [0001] The invention belongs to the technical field of silt solidification treatment, and specifically relates to a construction process for silt solidification soil. Background technique [0002] At present, many plots or rivers in the city have not been dredged in time, resulting in the deposition of a large amount of silt. At the same time, the silt is in a state of saturated flow plasticity, high water content, and high compressibility. This geological condition is likely to cause damage to the superstructure of the plot. Difficulty in construction and uneven settlement of the plot need to be dealt with. The traditional solution is to bury the silt nearby after being dug out. Although this can solve the problem of silt deposition, the silt also contains some harmful components such as toxic chemicals and pathogens. Direct discarding and burying will not only occupy a large amount of farmland, but also polluted environment. Therefore, it is very meaningful to...
