Description

Prestressed fiber grid cloth sand-blocking plate mold

Technical Field

The utility model relates to a prevent wind sand fixation equipment technical field, concretely relates to prestressing force fibre net cloth hinders husky board mould.

Background

Because the precipitation is little in winter and spring in northwest China, the dry earth surface forms sand storm under the drive of monsoon, not only cause the influence to people's life, but also can influence the normal operation of highway and railway, in order to reduce the sand storm to the harm along the highway and railway, the inside and outside of early highway and railway mainly use straw, reed and straw of crops to prick into the sand barrier of grass square and fix sand, but with the development of paper-making industry and modern agriculture, the raw material acquisition becomes very difficult, have appeared and adopted clay square or stone square of the person as the substitute of the square of straw, but because should not apply, use less; the adhesive materials such as emulsified asphalt, high molecular polymer, water glass and the like are sprayed on the surface of the quicksand to form a protective layer with a certain thickness, so the method is not widely popularized due to high manufacturing cost; the honeycomb sand-fixing barrier made of the nylon net sand barrier and the HDPE new material has a certain sand-blocking effect, but is easily blown out by strong wind, so that secondary environmental pollution is caused to the environment; in order to overcome the problems, researchers provide a construction mode for preparing the sand blocking plate by adopting a desert wind-blown sand local material mode, the construction mode solves the problems that materials are difficult to obtain in desert areas and building materials are deficient, and the concept of 'controlling sand by sand' is realized and the cost is reduced.

However, in the prior art, the desert sand is directly used for manufacturing the sand blocking plate, no reinforcing material is added to the concrete finished sand blocking plate mainly based on the aeolian sand and the cement, so that the sand blocking plate can play a sand blocking function or has the condition of seriously insufficient tensile, bending or bending resistance mechanical properties in the processes of construction, transportation and hoisting, in order to solve the problem, the fiber yarns are usually mixed in the sand blocking plate pouring engineering, the bending, tensile or bending resistance of the sand blocking plate reinforced by the fiber yarns is improved to a certain extent, but the improvement range is not large, but the bending, tensile or bending resistance of the sand blocking plate can be greatly improved by adopting a method of applying grid cloth, but the fiber grid cloth has certain elasticity, if the fiber grid cloth plays the maximum role in the sand blocking plate, the fiber grid cloth is required to be in a tight state in the sand blocking plate, and the sand blocking plate is in a shrinkage state by utilizing the elasticity of the fiber grid cloth, therefore, the sand-blocking plate is more compact, when the fiber mesh cloth in the prior art is laid, the fiber mesh cloth is in a loose state in the sand-blocking plate, so that the elasticity of the fiber mesh cloth is not utilized when the sand-blocking plate is prepared, the bending resistance and the folding resistance of the prepared sand-blocking plate cannot be well improved, however, a specially prepared sand-blocking plate mold is not provided in the prior art, when the sand-blocking plate is prepared by utilizing the mold in the prior art, the fiber mesh cloth in the sand-blocking plate is laid only by manually pulling, at the moment, the fiber mesh cloth is in a non-uniform stress state, a part of limiting mesh cloth is in a loose state, so that the elasticity of the fiber mesh cloth is not utilized when the sand-blocking plate is prepared, the bending resistance and the folding resistance of the prepared sand-blocking plate cannot be well improved, however, in order to ensure the bending resistance and the folding resistance of the sand-blocking plate to a certain extent, the thickness of the sand-blocking plate cannot be reduced too much, however, when the thick sand blocking plate is constructed, a large amount of labor force is consumed, construction is inconvenient, and waste of fiber mesh cloth and fine sand raw materials is caused. Therefore, the prestressed fiber mesh cloth sand-blocking plate mold which can ensure that the sand-blocking plate has good bending resistance and folding resistance is designed, the thickness of the sand-blocking plate can be further reduced, the utilization rate of raw materials is improved, and construction is facilitated has very important significance.
