Abstract

The utility model provides a protective structure for the side slope of an embankment in a rainy area, wherein at least 3 concrete longitudinal beams are longitudinally cast along the side slope of the embankment, a plurality of cross beams are transversely cast along the side slope, and anchor bars are arranged on the longitudinal beams and the cross beams at regular intervals; the metal grid net is laid on the whole slope surface, the position of the metal grid net, which is over against each longitudinal beam and each cross beam, is provided with two main ribs, the two main ribs are respectively arranged on two sides of anchor bars on the longitudinal beams and the cross beams, and a pressing plate is inserted into each anchor bar and is screwed with a fastening nut. The longitudinal and transverse beams, the metal grids and the grass planted in the grids can effectively reinforce the slope soil body and make the side slope more beautiful.

Description

Embankment side slope protection structure in rainy area

Technical Field

The utility model relates to a highway embankment side slope protection field, concretely relates to structure form that consolidates then grass planting afforestation carries out the protection to the side slope.

Background

Grass planting protection is the most common side slope protection form in the highway construction, in plain area or the little hilly area universal adoption, there is construction convenience, characteristics such as cost low, but have certain limitation simultaneously, when the high uniform height of side slope or side slope soil property are bad, adopt the grass planting protection, when the rainy season arrives, receive rainwater infiltration and erode, phenomenons such as slide and collapse can appear in the side slope, cause the influence to the roadbed overall stability, consequently, the grass planting can't play the guard action to the side slope, be unfavorable for the normal operation of road.

Disclosure of Invention

The utility model aims to overcome the limitation of current side slope grass planting protection method, provide one kind and can consolidate the side slope structure in order to resist the rainwash, can improve the embankment side slope protective structure who beautifies the effect again.

The technical scheme of the utility model as follows:

the utility model provides a rainy area embankment side slope protective structure which characterized in that: at least 3 concrete longitudinal beams are poured at equal intervals along the longitudinal direction of the side slope of the embankment, a plurality of cross beams are poured at equal intervals along the transverse direction of the side slope, and anchor bars are arranged on each longitudinal beam and each cross beam at intervals; the metal grid net is laid on the whole slope surface and comprises a plurality of criss-cross grid ribs, two main ribs are arranged at the positions, opposite to each longitudinal beam and each cross beam, of the metal grid net, the two main ribs are arranged on the two sides of the anchor ribs on the longitudinal beams and the cross beams respectively, a pressing plate pressing the main ribs on the two sides of the anchor ribs is inserted into each anchor rib, and a fastening nut pressing the pressing plate is screwed into the fastening nut.

The utility model has the advantages of it is following:

(1) the arranged longitudinal and transverse beams disperse the sliding force of the side slope soil and play a role in fixing the side slope soil body;

(2) in the rainy season, the longitudinal beam, the protective net and the grass planting participate in stress together to prevent the soil body of the side slope from collapsing;

(3) the longitudinal and transverse beams can be selected for cast-in-place and factory prefabrication construction according to the field conditions, and the flexibility is high;

(4) compare with conventional side slope grass planting method, the utility model discloses a with the side slope meshing, whole more pleasing to the eye, improved the visual effect of side slope protection.

FIG. 1 is a plan view of the side slope protection frame of the present invention;

FIG. 2 is a plan view of the whole structure of the slope protection of the present invention;

fig. 3 is a side sectional view of the slope protection structure of the present invention.

Detailed Description

As shown in fig. 1, 2 and 3, the utility model comprises at least 3 concrete longitudinal beams 2 which are vertically poured along the embankment side slope 1 and are arranged at equal intervals, and a plurality of cross beams 3 which are horizontally poured along the side slope and are arranged at equal intervals, wherein each longitudinal beam and each cross beam are provided with an anchor bar 4 at certain intervals; the metal grid net is laid on the whole slope surface and comprises a plurality of criss-cross grid ribs 5, two main ribs 6 are arranged at positions, just opposite to each longitudinal beam and each transverse beam, of the metal grid net, the two main ribs are respectively arranged on two sides of anchor ribs 4 on the longitudinal beams and the transverse beams, a pressing plate 7 pressing the main ribs on two sides of the anchor ribs is inserted into each anchor rib, and a fastening nut pressing the pressing plate is screwed into the anchor ribs. Grass 8 is planted in the grids of the metal grids.

The utility model discloses a construction method as follows: after the side slope is leveled, longitudinal beam and cross beam grooves are excavated on the side slope according to the drawing design, concrete is poured in the grooves according to the sequence of longitudinal and transverse directions, anchor bars are embedded in the concrete of the longitudinal and transverse beams, and after the concrete reaches the designed strength, a metal grid mesh is installed. Two ribs of the metal grid, which are opposite to each longitudinal beam and each cross beam, are arranged on two sides of the anchor rib on the longitudinal beam or the cross beam respectively, and then a pressing plate and a fastening nut are installed to complete the fixation of the protective net. And finally, planting grass in the grids of the metal grid.
