Slope with slow slope rate, Foundation trench excavation of earth and backfilling of earth are both relatively larger and the project is not economic;
In order to ensure winter construction quality according to backfilling of earthwork, masonry engineering, concrete engineering and reinforcement project corresponding quality control measures are proposed for winter construction, which can be used as references for winter construction.
Consequently the bedding and backfilling of the trench need special attention to provide the required lateral support.
This paper describes a new backfilling technology of full-range tailings consolidated by a special accelerating material for high water content SUS pension.
Taking tails which are consolidated with high water material as backfilling is a new type backfilling method.
Foam concrete wall used for light bet backfilling materials can reduce the vertical section load, also reduced the wall lateral load of the other side.
Taking advantage of attribute stack and backfilling technique,we can solve this problem radically.
Its capacity of resisting large external load enables it not to rely on lateral support of the soil, therefore its requirements on backfilling soil is lower than on flexible tubes.
The article tells us the constructing technics and the measure for quality control how to backfill sand or soil at the back of the structures by the real backfilling illustration in XiaoXiang freeway.
By taking the backfilling of foundation with soil mixture of clay, lime, coal slag and gravel as an example, the main factors affecting the compressive strength of this kind of soil mixture is analyzed through a series of physical and mechanical property test on the soil mixture.
Land reclamation technology includes surface humus soil stripping and piling, blocks the dregs dam. retaining dam, flood drainage guide, land leveling and backfilling of soil humus.
The performance and applying effect of the gelled material from the water quenching slag for backfilling are described.
