If the delay period for this project will affect developers pay to, it will seriously affect the reputation of the Daya Bay Economic and Technological Development Zone.
1.3 construction site environment
Near the site have a permanent road through municipal sludge dumping sites for field level in the region while a detour to pass to the permanent municipal roads. Trees around the more sparsely populated. Field-based projects designated excess spoil disposal earthwork fill region, the region as development land, there is a large reservoir needs filling, and the surplus earth ship out to the designated dumping sites, the distance 1 km, silt to the designated Sinotrans dumping sites, the distance of 2.5 km.
1.4 Project Geology
Field level in the region contribution has a small piece of nursery stock and buildings and other fixtures, in need of cleaning, the red line to the location of the Northeast have a pond, the need for drainage and silt clearance and transport. According to owners of quantities, of which three types of soil are 1418396.27m3, the soil is mainly loam, sandy clay; stonework has 90535.93m3, silt, sand with 17000m3.
1.5 The scope and scale
The total excavation of the project is about 1.52 million m3, the total fill volume is about 90,000 m3, Sinotrans spoil about 1.43 million m3, field level area of about 310,000 m2.
1.6 The main features of project
(1) The excavation, backfilling earthwork great, very tight schedule.
(2) mainly abandoned side of earth, reaching 1.43 million m3; stonework has 90535.93m3, be self-blasting, blasting required to obtain prior permission from the relevant departments handle the blasting permit for their operation. At the same time, blasting safety regulations must comply.
(3) of earth have filled approximately 90 000 m3, 90% required degree of compaction, soil moisture content and compacted material to strictly control the quality.
Field area with ponds, trees, buildings in need of treatment, deposition
