新建垃圾填埋场土工材料施工策划即土工膜施工方法详解
新建垃圾填埋场土工材料施工策划：
垃圾场施工，是一项较为困难的工程，要想更率的完成垃圾场施工。必须要有的施工部署策划方案。泰安瑞恒作为少数拥有特种防渗资质证书的环境工程厂家，现为您分享一般的垃圾场施工部署方案。
首先，采取大小临时工程及土石方工程同时并举，进场后为土石方工程提前开工做好三件事:一是抓好控制线复测工作，将全场中心线及高程闭合，确定构筑物位置，设置测点及临时测点；其次，是抓好场内的清理、清除与掘除工作；三是抓好临设（临时便道与临时房屋）的建设。
再者，采用多头平行作业，交叉作业，流水作业，充分利用工时及劳动空间。并且要合理安排垃圾场施工顺序，形成网络计划管理，实施日检、月检，保证形象进度的控制。
垃圾场施工方法和技巧详解
垃圾场施工方法和技巧详解:既然施工部署方案已经确定，那么，重要的自然就是施工方法和技巧了。
1、坐标点放样。用全站仪按施工图纸坐标放出坐标点，然后对原地貌进行高程测量，对断面高程进行复核，并报监理复核签证。并根据施工效率列出垃圾场施工中测量时间。
2、库区清表及场地平整对整个库区工程范围内的表层植被土、所有植被及其他可能影响地基土质量的物料进行清理，并根据施工效率列出垃圾场施工中物料清理时间。
3.库区土方开挖、回填、筑坝：对库区土方采用二次开挖方式，次先挖至分区堤坝标高高度，开挖的同时完成堤坝碾压回填，自三区和四区同时开挖。挖至标高后重新放线开挖库底。并根据施工效率列出垃圾场施工中开挖、回填、筑坝时间。
4、水平防渗工程施工:根据完成的基准面情况及时报监理验收，具备铺设条件的及时铺设防渗材料。并根据施工效率列出垃圾场施工中铺设防渗材料时间。
防渗工程中土工膜施工前铺设准备
防渗工程中土工膜施工前铺设准备
1. 铺设防渗土工膜前应由土建工程相应的合格验收证明文件。
2. 防渗土工膜裁切之前，应该准确丈量其相关尺寸，然后按实际裁切，一般不宜按图示尺寸裁切，应逐片编号，详细记录在表格上。
3. 铺设HDPE土工膜时应力求焊缝少，在保证质量的前提下，尽量节约原材料。同时也容易保证质量。
4. 膜与膜之间接缝的搭接宽度一般不小于10cm，通常就使焊缝排列方向平行于坡度，即沿坡度方向排列。
5. 通常在拐角及畸形地段，应是接缝长度尽量减短。除特殊要求外，在坡度大于1：6的斜坡上距顶坡或应力集中区域1.5米范围内，尽量不设焊缝。
6. 防渗土工膜施工过程中在铺设时，应避免产生人为褶皱，温度较低时，应尽量拉紧，铺平。
7. 防渗土工膜铺设完成后，应尽量减少在膜面上行走、搬动工具等，凡能对HDPE膜造成危害的物件，均不应放在膜上或携带在膜上行走，以免对膜造成意外损伤。
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.
