Abstract

A saltpetering prevention stone paving structure comprises a positioning support pier, a supporting blind ditch and floor bricks, wherein the positioning support pier is of a common concrete structure and is 40-200 mm high, the bottom of the positioning support pier is fixedly connected with a foundation structure layer, and the top of the positioning support pier is concave downwards; the supporting blind ditch consists of graded broken stones wrapped by geotextile, and a drain pipe is arranged at the bottom and placed between the supporting piers; the edge of the floor tile is stuck on the supporting pier by the saltpetering-proof cement. The utility model is suitable for a moist stone material in ground is mated formation, simple process, and economic nature is good, and overhead structure can effectively avoid the production of whiskering.

Description

Stone paving structure capable of preventing efflorescence

Technical Field

The utility model belongs to the structure of mating formation on ground specifically is a prevent stone material structure of mating formation of whiskering.

Background

The wet pasting method has simple construction and lower manufacturing cost, and is a main method for hard paving the gardens. The hard pavement installed by the wet sticking method is easy to generate a saltpetering phenomenon in places such as the surface and gaps of the hard pavement due to repeated exposure to rainwater or wet weather in the using process, and the saltpetering phenomenon is not faded repeatedly throughout the year, so that the appearance and quality of the building engineering are seriously influenced, and the bonding strength among all layers in the hard pavement is also greatly influenced. Two major factors of the phenomena of efflorescence are the penetration of alkalines in the cementitious cement and of water. The common anti-efflorescence measures at present are to use low-alkali cement (anti-efflorescence cement) instead or use suspended (suspended) pavement of a steel keel frame instead, but for large-area pavement, the two measures can greatly increase the cost. Therefore, it is an improvement technology with practical application value to explore a measure which can prevent the efflorescence and control the cost.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming prior art's not enough, providing a prevent stone material structure of mating formation of whiskering, rational in infrastructure, simple process, overall economy is good, has avoided cement of large tracts of land to paint, has prevented the production of whiskering from the root, and the design of support nature french drain moreover can the drainage, can play the effect of supporting the stone material again, and the material is cheap easily obtained.

The technical scheme of the utility model as follows:

the utility model provides a prevent stone material structure of mating formation of whiskering, is including location support mound, support nature french drain and ground brick, the location support mound be ordinary concrete structure, bottom and foundation structure layer rigid coupling, the top is spill down, the location support mound is separated by certain distance each other and is set up between ground brick and foundation structure layer, the support nature french drain by geotechnological cloth parcel graded broken stone and constitute, support nature french drain bottom is provided with the drain pipe, the support nature french drain is placed between the support mound, ground brick edge adopt to prevent that the whiskering pastes on supporting the mound.

The saltpetering-preventing stone paving structure is characterized in that the height of the supporting blind ditches is consistent with that of the lower bottom surface of a floor tile, so that a local supporting effect is achieved; the width of the supportive blind ditch is determined by the strength of the floor tiles.

The saltpetering-preventing stone paving structure is characterized in that the height of the positioning support pier is 40-200 mm.

The saltpetering-preventing stone paving structure is characterized in that a small hole structure is arranged on the geotechnical cloth used by the supporting blind ditches, and water permeability is improved.

The saltpetering-proof stone paving structure is characterized in that saltpetering-proof cement is smeared in a concave groove at the top of a support pier during paving.

The saltpetering-preventing stone paving structure is characterized in that a small hole is formed in the pipe wall of a drain pipe in a supporting blind ditch.

The utility model discloses a rational in infrastructure, simple process, the totality economy is good, has avoided the cement of large tracts of land to paint, has prevented the production of whiskering from the root, and the design of support nature french drain can the drainage moreover, prevents that water from up permeating to prevent the production of whiskering, can play the effect of supporting the stone material again, and the material is cheap easily obtained, realized reaching the purpose of preventing whiskering under the prerequisite of control cost, had fine practical application and worth.

Drawings

Fig. 1 is a schematic view of the present invention;

in the figure, 1 — positioning the support pier; 2-supportive blind ditches; 3-floor tile; 4, a water drainage pipe; and 5, a basic structure layer.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in figure 1, the utility model relates to a saltpetering-proof stone paving structure, which comprises a positioning support pier, the supporting blind ditch is composed of geotextile wrapped graded broken stones, the bottom of the supporting blind ditch is provided with a drain pipe, the drain pipe longitudinally extends in the supporting blind ditch (the supporting blind ditch is a cross section in figure 1), the supporting blind ditch is placed between the supporting piers, a prepressing form is adopted after placement, so that the top elevation meets the design requirement, the height of the supporting blind ditch is consistent with the lower bottom surface of the floor brick, and a local supporting effect is achieved; the width of the supportive blind ditch is determined by the strength of the floor tiles. When the floor tile is paved, the lower concave groove at the top of the support pier is coated with the saltpetering-proof cement, and the edge of the floor tile is stuck on the support pier by the saltpetering-proof cement. Because the anti-efflorescence cement is only coated on the top of the support pier, compared with the conventional construction method, the coating amount of the cement is greatly reduced, and the generation of efflorescence is fundamentally prevented. The geotechnique cloth that the supportability french drain adopted is equipped with the aperture structure, increases the water permeability, and the geotechnological cloth connected mode of supportability french drain is the overlap joint, forms by the mutual overlap joint of polylith geotechnological cloth, forms longitudinal extension, then with geotechnological cloth both sides after the rubble is joined in marriage to the parcel level fixed in the mutual overlap joint in top. The pipe wall of the drain pipe in the supporting blind ditch is provided with a small hole, and water in the supporting blind ditch can enter the drain pipe from the small hole and then is discharged from the far end of the drain pipe. The supporting blind ditch has good water permeability, can drain water and prevent water from permeating upwards so as to prevent the generation of saltpetering, can also play a role in supporting stone,

the above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
