1. Introduction of bidirectional plastic grille Bidirectional plastic grille is made of high polymer by extrusion to form a plate, punched, and then stretched vertically and horizontally. Bidirectional stretch plastic geogrid is suitable for various dykes and roadbed reinforcement, slope protection, cave wall reinforcement, and foundation reinforcement carried by large airports, parking lots, wharf yards, etc. Because bidirectional plastic grille has many advantages: such as increasing the bearing capacity of the road (ground) foundation and extending the service life of the road (ground) foundation. It can effectively prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy. Moreover, the construction is convenient, time-saving, labor-saving, shortening the construction period, and reducing maintenance costs. In addition, it can also replace metal mesh for underground false top nets in coal mines. Therefore, bidirectional plastic grating has been widely used in actual construction, and the foundation reinforcement construction effect suitable for large-scale bearing is remarkable. Two. The main application scope of bidirectional plastic grille is: subgrade reinforcement of various highways, railways, airports; foundation reinforcement carried by large parking lots and wharves; slope protection of railways and highways, culverts enhancement; secondary enhancement of soil slope enhanced by unidirectional stretching geogrid, further enhancing soil slope, preventing soil erosion; mine, tunnel reinforcement. 3. construction process requirements of bidirectional plastic grille 1. The paving surface of the geogrid should be relatively flat. After the paving layer is qualified, in order to prevent vertical skew, first draw a white line or hanging line on the paving layer according to the width, you can start paving, and then fix the end of the grille with iron nails (8 nails per meter wide, fixed at a uniform distance). 2. After fixing the end of the grille, use a paver to slowly pull the grille forward, manually tighten and straighten each 10 meters long until one roll of grille is laid, and then another roll is laid, and the operation is the same as before. After laying one roll, use a 6T-10T roller to roll it in the forward direction from the starting point. (If paved on the middle surface layer and leveling layer, it is advisable to use a steel roller roller; if the grille is laid directly on a concrete pavement, a rubber roller roller is appropriate.) 3. Paving: The length of the section to be laid in units of roll length is used. After the length of the section to be paved is paved, the paving quality is checked as a whole, and then the next section is paved. When the next section is paved, the grille and the grille can be lapped with a lap length of 10-15CM, and the second section is paved in the forward direction after fixing it with iron nails or wooden wedges. By analogy, the operation requirements are the same. Why is the price of plastic geogrid of the same specification so different from different manufacturers? Are these so-called “same specification” plastic geogrid of different quotes really the same? If there is a difference, where is the difference? Today, Zhengze Engineering Materials Co., Ltd. will explain in detail for you: Where is the price difference of plastic geogrid? 02 02 02 02 02 02 02 02 02 02 02 02 02 When it comes to the price, the first thing we think about is the difference in raw materials. Indeed, Zhengze plastic geogrid raw materials are divided into polypropylene particles and polyethylene particles. The raw materials of the two are different, and the plastic geogrid produced is also different; in the process of production, the plastic particles have fluidity, plasticity, and can be processed under certain conditions. Using this characteristic, we heat the polypropylene raw material through the machine to make the raw material flow state, so that it can be processed by the machine; when normal conditions are restored (such as removing pressure and cooling), it still maintains the shape of the processing Polymers are called plastics.
