Background

The highway sand damage prevention and control refers to technical measures for preventing and controlling the damage of wind erosion and sand burying to the highway in the wind and sand areas. The wind-blown sand area of China has about 70 km2 and is mainly distributed in north latitude

And Dong Jing

In the meantime. The wind erosion is the damage phenomena of cutting down, hollowing and collapsing of the roadbed and the like of road shoulders and side slopes of the highway under the action of wind and sand erosion, the sand burying is the phenomenon that the roadbed is buried by accumulated sand due to the movement of wind and sand flows and sand dunes, and particularly the sand burying has a larger danger.

At present, engineering sand-blocking measures mainly comprise sand-fixing measures and sand-blocking (blocking) measures, and the sand-blocking measures are applied more generally. Common sand blocking measures comprise a concrete sleeper sand blocking wall, a PE net high vertical sand barrier, a reed sand blocking fence and the like, and the engineering sand prevention measures play a certain role in existing sand storm disaster prevention and control engineering of railways, highways and the like, but generally have the problems of high construction difficulty, high manufacturing cost, low sand prevention benefit, difficulty in maintenance and replacement and the like.

SUMMERY OF THE UTILITY MODEL

The utility model provides a aeolian sand highway section keeps off husky device, the effectual current problem of keeping off husky measure construction degree of difficulty big, the cost is high, the sand prevention benefit is low and the maintenance is changed the difficulty of having solved, and this device can be with the stable fixed arrangement of fender sand board segmentation through the installation mode of concatenation formula, and the site operation is simple and easy simultaneously, can prefabricate, and the later stage is changed portably.

In order to achieve the above object, the utility model discloses a technical scheme specifically as follows:

the utility model provides a aeolian husky highway section sand blocking device, includes a plurality of cement bases 1 of burying admittedly on the highway subgrade, its characterized in that: install triangular frame 3 on the cement base 1, install through triangular frame 3 and keep off sand board mounting bracket 4, keep off sand board mounting bracket 4 and include angle frame 5, crossbearer 7, sloping frame 8 and installation notch 9, all install angle frame 5 through bolt group 6 on two sets of perpendiculars of triangular frame 3, be fixed with installation notch 9 through crossbearer 7 and sloping frame 8 on angle frame 5, it is fixed with to keep off sand board 11 to peg graft between two sets of relative installation notches 9 that set up on adjacent cement base 1, a plurality of keeps off sand board 11 and splices each other, forms integral type and keeps off sand wall.

The cement base 1 is provided with a force application auxiliary plate 2 along the roadbed direction.

The triangular frame 3 is provided with two or more than two sand baffle mounting frames 4.

The mounting notches 9 are connected by reinforcing rods 10.

The utility model has the advantages that: 1) All equipment arranged on the cement base can be prefabricated in a factory, and the equipment is installed on the site after the prefabrication is completed, so that the installation is convenient and fast, and the time and the cost are saved.

2) This device can guarantee the stability of fender sand board under the wind-force effect through the cement base, three arris framves and a plurality of fender sand board mounting bracket 4 that have the auxiliary board of exerting oneself, can not produce the slope or collapse, can effectually block the grains of sand.

3) The sand blocking plate installation mode of the splicing type is adopted, and the sand blocking plate is easy to damage due to long-time sand particle collision and corrosion damage of all factors. The device is convenient to replace, only specific modules are replaced, large-area replacement is not needed, and cost is saved.

Detailed Description

The technical solution of the present invention is further described by the following specific embodiments with reference to the accompanying drawings:

example 1

As shown in fig. 1-4, the utility model provides a sand blocking device for a windy sand section, which aims to provide a sand blocking wall with convenient installation and replacement. This keep off husky wall adopts the installation mode of concatenation formula, and concrete mounting structure is as follows:

as shown in fig. 1 and 2, the sand guard 11 is installed by a cement base 1, a triangular frame 3 and a sand guard installation frame 4 composed of a plurality of steel structures.

As shown in fig. 3, the auxiliary force plate 2 is arranged on the cement base 1, the auxiliary force plate faces the road side, and both the cement base 1 and the auxiliary force plate 2 are embedded in the road base layer. The cement base can be effectively prevented from being displaced or inclined under the action of wind power, and the stability of the whole device is ensured.

The cement base 1 is provided with a triangular frame 3, and the triangular frame 3 is of a high-strength steel frame structure.

A plurality of sand baffle mounting frames 4 are arranged through the triangular frame 3. The sand blocking plate mounting rack 4 consists of two groups of angle racks 5, two groups of cross frames 7, two groups of inclined frames 8 and two groups of mounting notches 9. The angle bracket 5 can be fixed on the triangular bracket 3 through a bolt group 4, and a cross frame 7 and an inclined frame 8 are arranged on the angle bracket 5.
