Sludge superficial layer curing agent solidification continuous construction method

Abstract

The invention discloses a sludge superficial layer curing agent solidification continuous construction method. The curing agent and the sludge are uniformly stirred, then the construction surface is compacted by using stirring equipment, the compacted construction surface is a construction unit, an iron plate is laid below an excavator, the construction unit serves as an operation platform, and the sludge in connected areas is continuously processed according to a construction mode of block-by-block construction and a well-shaped propulsion. The sludge solidification structure with relatively low water content in china is to being buried in different places after being treated, a shallow-layer sludge consolidation continuously construction method is adopted in foreign countries, but geotechnical cloth, gravel and boards need to be laid on the surface of the solidified sludge so that the continuously construction can be carried out, the construction method only has the transverse construction and no the longitudinal construction, and the plate body stabilization layer is not provided with a plate frame structure. According to the construction method, with the water content of more than 130%, the transverse and longitudinal construction method is adopted to realize the shallow-layer sludge consolidation continuous plate frame structure construction, and the construction is more flexible, simple and effective compared with the foreign countries.

Description

technical field

[0001] The invention relates to a continuous construction method for consolidating a silt superficial layer with a solidifying agent, and belongs to the technical field of large-area soft soil foundation treatment. Background technique

[0002] One of the commonly used construction methods for building fields and roads on soft ground is to squeeze and silt the mountain soil. With the rapid development of national economic construction, the contradiction between the demand for construction land and the occupation of cultivated land has become increasingly prominent. In order to protect people's livelihood, the state has set a red line of 1.8 billion mu of cultivated land, and builders have to turn their attention to rivers, lakes, seas depositional place. The silt layer of marine deposits is tens of meters deep, and the silt depth of artificial dredged soft foundation is also nearly 10 meters. This kind of silt foundation has extremely low bearing capacity an...
