详细介绍

对铺设现场的下承层表面必须要求压实平整，无尖刺突起物或砾石突起来源www.bdsh5.com。填土层表面应平整,严禁有碎块石等坚硬凸出物,在距土工格栅8cm以内的路堤填料,其最大粒径不得大于6em。

The surface of the lower bearing layer on the laying site must be compacted and flat without sharp protrusion or gravel protrusion. The surface of the filling layer shall be flat and free of hard protrusions such as broken stones. The maximum particle size of the embankment filling within 8cm from the geogrid shall not be greater than 6em.

在铺设安装连接固定过程中,土工格栅主要受力的纵向方向应垂直于路基的轴线方向,格栅网格表面要确保平整,不允许有褶皱,格栅四边张紧。必要时,可以采用插钉等措施固定土工格栅于填土层表面。

In the process of laying, installation, connection and fixation, the longitudinal direction of the main stress on the geogrid shall be perpendicular to the axis direction of the subgrade, and the surface of the geogrid grid shall be smooth without wrinkles, and the four sides of the geogrid shall be tensioned. If necessary, measures such as inserting nails can be adopted to fix the geogrid on the surface of the fill layer.

顶层格栅的纵向受力方向要求通长无接头，双幅搭接处可以人工绑扎搭接,搭接宽度应大于20 cm。如铺设宽幅中，设置的格栅在两层以上,层间应错缝设置本~地~生~活~网。大面积铺设后,需安排专人调整其平直度。覆盖一层砂砾未碾压前,应再次用人工或机具张紧格栅,力度要均匀,使格栅在土中始终保持为绷直受力状态。土工格栅上的第一层填土摊铺宜采用轻型推土机或前置式装载机,填料的摊铺与填筑从路基的纵向轴线位置开始,对称地向两侧填土。

The longitudinal stress direction of the top grid shall be full length without joint. The double lap joint can be manually bound and lapped, and the lap width shall be greater than 20 cm. If the grid set in the laying width is more than two layers, staggered joints shall be set between layers. After large-scale laying, special personnel shall be arranged to adjust its straightness. Before covering a layer of gravel and rolling, the grid shall be tensioned again by manpower or machines and tools with even force to keep the grid in a straight stress state in the soil. The first layer of fill on the geogrid should be paved by light bulldozer or front loader, and the filling and paving should start from the longitudinal axis of the subgrade and fill symmetrically to both sides.

车辆、施工机械沿路堤的轴线方向行驶。土工格栅摊铺以后,应及时摊平填料,间隔时间不应超过48 h,加筋路堤‘的边坡防护应和路堤的填筑同时进行，在夏季施工如不能及时填筑，应及时对已铺筑完成顶面的土工格栅采取覆盖等临时保护措施,以避免其受到阳光、雨水的直接暴晒和侵蚀b~d~s~h~5~c~o~m。填料的选择和压实。

Vehicles and construction machinery shall travel along the axis direction of the embankment. After the geogrid is paved, the filler shall be paved in time, with an interval of no more than 48 hours. The slope protection of the reinforced embankment shall be carried out at the same time as the embankment filling. If the construction cannot be filled in time in summer, the geogrid on the paved top surface shall be covered and other temporary protection measures shall be taken in time to avoid the direct exposure and erosion of sunlight and rain. Selection and compaction of fill.

土工格栅施工中的填料应优先选取砾类土和砂类土等力学性能稳定、受含水量影响小的土质。所选填料粒径不得大于铺筑层厚的2/3或15 cm,同时控制填料级配，以保证压实密实性。格栅铺设搭接完成后,应及时填土覆盖。为确保施工的连续性,应合理安排作业计划，采取铺设、回填的循环流水作业法本地生活网。施工中控制好最佳含水量,为提高路基整体稳定性,碾压的顺序是先两侧后中间。碾压中压轮不能直接与筋材接触,未压实的格栅不允许车辆在上面行驶,以免筋材错位。

In the construction of geogrid, gravel soil, sand soil and other soil with stable mechanical properties and little influence of water content shall be selected as the filler. The particle size of the selected filler shall not be greater than 2 / 3 or 15 cm of the thickness of the paving layer, and the grading of the filler shall be controlled to ensure the compactness. After the grid is laid and overlapped, it shall be filled and covered in time. In order to ensure the continuity of construction, the operation plan shall be reasonably arranged, and the circulating flow operation method of laying and backfilling shall be adopted. In order to improve the overall stability of subgrade, the order of rolling is from two sides to the middle. The rolling medium pressure wheel shall not be in direct contact with the reinforcement, and vehicles are not allowed to drive on the uncompacted grid to avoid the dislocation of the reinforcement.

土工格栅铺施工时要注意以下几点：

Pay attention to the following points during the construction of geogrid:

1.存放和铺设土工格栅时，避免曝晒和长时间暴露，以免性能劣化。

1. When storing and laying geogrid, avoid exposure to the sun and long time to avoid performance degradation.

2.垂直于线路方向铺设，搭接符合设计图纸要求，联结牢固，在受力方向联接处的强度不低于材料设计抗拉强度，且其叠合长度不小于20cm。

2. It shall be laid perpendicular to the direction of the line, the lap joint shall meet the requirements of the design drawing, the connection shall be firm, the strength of the joint in the direction of stress shall not be lower than the design tensile strength of the material, and the overlapping length shall not be less than 20cm.

3.土工格栅质量符合设计图纸的规定VLkF。

3. The quality of geogrid shall meet the requirements of design drawings.

4.施工保持连续性，不出现扭曲、折皱、重叠，注意绷紧格栅使其受力，用人工拉紧，使其均匀、平整、紧贴下承面，采用插钉等措施固定。

4. The construction shall be continuous without distortion, wrinkle or overlap. Pay attention to tighten the grid to make it stressed. Tighten it manually to make it even, flat and close to the lower bearing surface. Fix it with spigot and other measures.

5.土工格栅铺设时，长孔方向和线路横断面方向一致，土工格栅要拉直拉平。格栅端头按设计处理。

5. When the geogrid is laid, the direction of the long hole shall be consistent with the direction of the cross section of the line, and the geogrid shall be straightened and leveled. The grating end shall be treated according to the design.

6.土工格栅摊铺后及时填筑填料，间隔时间不超过48h，以避免其受到阳光的直接曝晒。

6. Fill the filler in time after the geogrid is paved, and the interval time shall not be more than 48h, so as to avoid direct sunlight exposure.

相信大家看完以上内容以后，应该对土工格栅填筑路基需要注意哪些问题有了一定的了解了，希望会对大家有所帮助吧b_d_s_h_5_c_o_m。

I believe that after reading the above content, you should have a certain understanding of the problems that need to be paid attention to when geogrid is used to fill subgrade. I hope it will help you.
