The new landfill geotechnical materials in construction planning:

Garbage dump construction, is one of the more difficult works, to more efficient complete landfill construction.Must have excellent construction deployment plan. Tai'an Ruiheng as minority has special imperviousqualification certificate of environmental engineering manufacturers, is for you to share the general garbage dump construction plan.

First of all, take the size of temporary works and earth works simultaneously, after entering the arena for the earth works started ahead of doing three things: one is to do a good job of the line of control survey work, will be the center line and elevation closing, determine the building location, a set of permanent and temporarymeasuring point measured points; secondly, is to do a good job of the clean, clear with the digging work; threeis to do a good job of the temporary ( temporary road and the construction of temporary housing ).

Furthermore, using multiple parallel operation, crossover operation, production, make full use of time andspace of work. And reasonable arrangements for landfill construction sequence, form a network plan management, implementation of Japan seized, seized, ensure that the image of progress control.

Garbage dump construction methods and techniques.

Garbage dump construction methods and techniques detailed: since the construction plans have been identified, then, one of the most important natural is the construction methods and skills.

1, coordinate lofting. According to the construction drawings with total station coordinate released coordinates,then the original landform height measurement, the section elevation for review, and submit to supervisioncheck visa. According to the construction efficiency of landfill construction measurement time list.

In 2, clearing and leveling the ground on the entire reservoir projects within the scope of the surface vegetation soil, vegetation and other all may affect the quality of foundation soil material for cleaning, and according to the construction efficiency list landfill materials during the construction of cleaning time.

Earth excavation, backfilling, 3 reservoir dam in the reservoir area by two times: Earthwork excavation, the firstdig to partition the dam height, the dam roller compacted backfill excavation at the same time, since the threearea and the four area at the same time excavation. Dig to elevation to Actinomyces excavation bottom.According to the construction efficiency list dump excavation, backfilling, dam construction time.

4, horizontal seepage control engineering construction: according to the datum and the times supervisionacceptance, with laying condition timely paved impervious material. According to the construction efficiencylist dump construction middle seepage proof material time.

Impervious geomembrane laying preparation before construction

Impervious geomembrane laying preparation before construction

1 impermeable geomembrane before the civil engineering a corresponding qualification and acceptance certificate.

2 geomembrane to cut before, should measure the correlation dimension, then according to the actual cutting,the general should not be to press the cutting size, should one piece number, recorded in detail in specialform.

3 laying HDPE geomembrane should strive to weld the least, under the premise of guaranteeing quality, as far as possible to save raw material. It is also easy to ensure quality.

4 membrane and membrane joints between lap width not less than 10cm, usually make welds arrangement direction parallel to the maximum slope, along the slope direction.

Normally in the corner and deformity of 5 lots, should be the length of the joint to reduce short. Except special requirement, the slope is greater than 1:6 slope away from the top of slope and the stress concentration area within 1.5 meters, as far as possible without weld.

6 geomembrane during laying, should avoid artificial fold, when the temperature is low, should be taut, paving.

7 laying geomembrance completed, should be minimized in the membrane surface running, move tool, that can HDPE membrane damage objects, shall not put in the film or carried in the film walk, so as to avoidaccidental injury of membrane.
