       土工格栅作为一种土工合成材料,广 泛应用于路基工程的边坡加筋补强、地基加筋补强、加筋土挡墙等,土工格栅在铺设过程中需要张紧,并固定好,然后进行填土欢迎www.bdsh5.com。格栅的张拉程度与格栅在加筋土结构中的受力、位移都有直接关系,所以格栅铺设中的张拉工作至关重要。今天山东土工格栅厂家就带大家了解一下土工格栅的铺设结构和方向。

      Geogrid, as a kind of geosynthetics, is widely used in slope reinforcement, foundation reinforcement, reinforced earth retaining wall, etc. in subgrade engineering. Geogrid needs to be tensioned, fixed and filled during the laying process. The tension degree of the grid is directly related to the stress and displacement of the grid in the reinforced soil structure, so the tension work in the grid laying is very important. Today, Shandong geogrid manufacturer will show you the laying structure and direction of geogrid.

       土工格栅铺设结构,包括土工格栅及连接棒,所述土工格栅的一-侧为用于包裹所述土工格栅铺设结构的边侧的土工格栅包裹侧,所述士工格栅的另一侧为土工格栅固定侧，所述土工格栅设置有若干层,每层所述土工格栅上填筑填料,其特征在于:距所述土工格栅固定侧的端部1.5~2m处设有沟槽,所述土工格栅固定侧铺设于所述沟槽内并填筑填料,所述土工格栅包裹侧回折并经所述连接棒与相邻层所述土工格栅固定连接本_地_生_活_网。

       The geogrid laying structure includes geogrid and connecting rod. One side of the geogrid is the wrapping side of geogrid used to wrap the side of the geogrid laying structure. The other side of the geogrid is the fixing side of geogrid. The geogrid is provided with several layers, each layer of the geogrid is filled with filler, The utility model is characterized in that: a groove is arranged 1.5-2m away from the end of the fixed side of the geogrid, the fixed side of the geogrid is laid in the groove and filled with filler, the wrapped side of the geogrid is folded back and is fixedly connected with the Geogrid of the adjacent layer through the connecting rod.

       土工格栅铺设结构,其特征在于:所述沟槽的沟深为20~25cm,所述沟槽的低部宽度为30~35cm。根据权利要求1所述的土工格栅铺设结构,其特征在于:所述连接棒与靠近所述土工格栅包裹侧的所述土工格栅铺设结构的端部之间距离小于150m。根据权利要求1所述的士工格栅铺设结构,其特征在于:所述土工格栅铺设结构的边侧进一步包括护坡袋,所述护坡袋被包裹于所述土工格栅内本_地_生_活_网。

       The geogrid laying structure is characterized in that the trench depth of the trench is 20-25cm, and the lower width of the trench is 30-35cm. The geogrid laying structure according to claim 1, which is characterized in that the distance between the connecting rod and the end of the geogrid laying structure close to the wrapped side of the geogrid is less than 150m. The taxi grating laying structure according to claim 1, which is characterized in that the side of the geogrid laying structure further comprises a slope protection bag which is wrapped in the geogrid.

       目前,常用的土工格栅铺设结构为包裹式土工格栅铺设结构,即土工格栅相对于路堤边坡内侧一端 铺设于路堤边坡之中,土工格栅外侧一端回折一 定 长度铺设于路堤边坡之中,而上述土工格栅铺设结构施工人员靠人力去拉拉力效果达不到、格栅张拉后需要U形钉或木楔子固定,但对张紧作用不大,同时由于土工格栅回折长度较短,土工格栅的抗拔力有限,同时较短的回折长度也使土工格栅对填料的约束作用及填料对土工格栅的锚固作用也有限。因此,设计一种定位装置新型的土工格栅铺设结构以解决土工格栅涨紧作用小进而对填料的约束性较差的技术问题是非常有必要的。

       At present, the commonly used geogrid laying structure is the wrapped geogrid laying structure, that is, the geogrid is laid in the embankment slope relative to the inner end of the embankment slope, and the outer end of the geogrid is folded back for a certain length and laid in the embankment slope, However, the above-mentioned geogrid laying structure construction personnel can not achieve the pulling force effect by manpower. After the geogrid is tensioned, U-nails or wooden wedges are needed to fix it, but it has little effect on the tension. At the same time, due to the short fold back length of geogrid, the pull-out resistance of Geogrid is limited, At the same time, the short fold back length also makes the constraint effect of Geogrid on the filler and the anchoring effect of filler on geogrid limited. Therefore, it is very necessary to design a new type of geogrid laying structure with positioning device to solve the technical problem that the geogrid has little tension and poor constraint on the filler.

       铺设时，土工格栅的栅肋方向与路线纵缝受力方向一致，才能够发挥土工格栅应有的作用，而有的施工人员在施工中往往把土工格栅铺设的方向与纵缝受力方向相反，结果没有起到应有的作用，还造成人工、材料、机械的浪费bdsh5.com。在铺设土工格栅时，土工格栅中心与路基纵缝的中心偏离，土工格栅的两侧受力不均匀。

       When laying, the grid rib direction of the geogrid is the same as the stress direction of the longitudinal joint of the route, so that the geogrid can play its due role. However, some construction personnel often put the geogrid laying direction opposite to the stress direction of the longitudinal joint in the construction, resulting in the failure to play its due role, resulting in the waste of labor, materials and machinery. When laying the geogrid, the center of the geogrid deviates from the center of the subgrade longitudinal joint, and the forces on both sides of the geogrid are uneven.

       土工格栅铺设的不牢固，或在上填筑料之前铺设的时间较长，就会影响其工艺质量。因为受外界影响因素有很多，如：刮风、行人及车辆等，如不慎将土工格栅掀开，则在进行重新铺设时不仅浪费时间，也无法保证施工工艺www.bdsh5.com。土工格栅在填土和推平时，不讲究科学的施工工序将土工格栅损害，或路基填土处理不到位以及重新返工处理时将土工格栅损坏。

       If the geogrid is not laid firmly, or the laying time before filling material is long, its process quality will be affected. Because there are many factors affected by the outside world, such as wind, pedestrians and vehicles, if the geogrid is inadvertently lifted, it will not only waste time, but also can not guarantee the construction process when it is re laid. When the geogrid is filled and pushed, the geogrid is damaged due to not paying attention to scientific construction process, or the subgrade fill is not treated in place and reworked.

       土工格栅铺设结构的具体实施过程如下:首先在所述土工格栅1铺设之前,在距所述土工格栅包裹侧端部1.5~2m处挖一个沟深为20~25cm,低部宽度为30~35cm的所述沟槽5,然后将所述土工格栅固定侧12铺设于所述沟槽5内并进一步在所述沟槽5内填筑所述填料3,之后在所述土工格栅1上层填筑一定厚度的所述填料3,填筑之后在该层所述填料3的端部铺设若干所述护坡袋4,再将所述土工格栅1向上回折一定长度,包.裹住该层所述填料3以及所述护坡袋4,再将回折的所述士工格栅1拉紧后通过所述连接棒2。

       The specific implementation process of the geogrid laying structure is as follows: first, before the geogrid 1 is laid, a trench 5 with a depth of 20-25cm and a width of 30-35cm at the bottom is dug at a place 1.5-2m from the end of the wrapped side of the geogrid, and then the fixed side 12 of the geogrid is laid in the trench 5 and the filler 3 is further filled in the trench 5, Then fill the filler 3 with a certain thickness on the upper layer of the geogrid 1, after filling, lay a number of slope protection bags 4 on the end of the filler 3 of the layer, fold the geogrid 1 upward for a certain length, wrap and wrap the filler 3 and the slope protection bag 4 of the layer, then tighten the folded geogrid 1 and pass the connecting rod 2.

       相信大家看完以上内容以后，大家应该对土工格栅的铺设结构及铺设方向有所了解了，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 know the laying structure and direction of geogrid. I hope it will help you.
