Description
Technical field
The present invention relates to the slope retaining technology in geotechnical engineering field, particularly relate to a kind of solidified earth barricade and constructional method thereof.
Background technology
Retaining wall refers to that supporting roadbed bankets or the hillside soil body, prevents from banketing or the structure of soil deformation unstability. Traditional retaining wall pattern has gravity type boat davit, cantilevered, buttress type and reinforced earth bulkhead etc., gravity retaining wall, refers to rely on the retaining wall of wall body deadweight opposing soil body wall pressure. Gravity retaining wall available block stone, slabstone, concrete precast block are as masonry, or adopt sheet stone concrete, concrete to carry out entirety and build. Cantilever retaining wall is made up of base plate and the stalk that is fixed on base plate, main by the weight of banketing on base plate to maintain stable retaining wall, primarily of wall, toe board and heel slab three reinforced concrete members compositions. Counterfort retaining wall refers to the armstand along cantilever retaining wall, the counterfort that adds one at a certain distance, by the retaining wall that wall is connected with heel slab. Reinforced earth retaining wall refers to that the reinforced earth being with by banketing, draw and veneer building block forms bears the retaining wall of soil body wall pressure. The wall body of above-mentioned retaining wall is built by laying bricks or stones by Reinforced Concrete Materials mostly. Needing to carry out a large amount of soil excavation and backfilling working in retaining wall construction process, construction cost is big.
Soil-solidified-agent is a kind of novel energy-saving environment-friendly engineering materials for solidifying all kinds of soil by multiple inorganic, organic materials synthesis. The essence of soil-solidified-agent curing soil is that physical-chemical reaction occurs between soil particle, improves the contact surface between soil particle, the connection mechanism between reinforced soil particle. Its physical-chemical reaction can be concluded as solidifying agent and soil constituent carry out ionic adsorption and exchange, soil particle is made to be tending towards cohesion, chemical reaction generates novel substance and strengthens the connection between soil particle, and resultant volumetric expansion improves and hole between filling soil particle. Under the effect of Compaction Effort, make solidified earth be easy to compacting and stablize, thus form one-piece construction, and reach the conventional degree of consolidation that can not reach. Through the soil that soil-solidified-agent processed, the performances such as its intensity, degree of compactness, the modulus of resilience are obtained for very big raising, thus extend the work-ing life of engineering, save maintenance of works cost.
Soil-solidified-agent has mineral-type, ionic species, high score subclass and biological enzyme etc. dissimilar, and the development of current domestic soil-solidified-agent mainly concentrates on mineral-type solidifying agent aspect. Soil-solidified-agent can substitute the traditional building materials such as a large amount of lime, cement, flyash, rubble, gravel, saves resource, the energy, Economization on land, and protection vegetation, is conducive to ecological environmental protection, has good economy, environmental benefit. Gelling material more insoluble special problems when soil fixation such as cement, lime, flyash can also be solved, have in the middle of unique soil solidification effect and practicality, the basic unit being widely used in highway and the construction of the engineering such as subbase, water conservancy bank protection widely.
In view of this, it is necessary in conjunction with soil stabilization, the construction of existing soil barricade is further improved.
