Abstract
A geogrid component applicable to an abutment of a bridge and a culvert comprises geogrid, wherein a pressing plate and a supporting steel plate are respectively arranged on an upper surface and a lower surface of the tail portion of the geogrid, and the tail portion of the geogrid is connected with pre-buried steel bars on the abutment of the bridge and the culvert through bolt fasteners. The geogrid component applicable to the abutment of the bridge and the culvert summarizes processing schemes of the abutment of the bridge and the culvert all over China, and the schemes are modified and innovated, water-permeable materials and the geogrid component are used together for processing back filling of the abutment of the bridge and the culvert, subgrade settlement caused by seepage of rainwater is avoided, the overall stress of an abutment area to a base is optimized, and the phenomenon of vehicle jumping is well avoided.
Description
Technical field
The utility model belongs to the bridge construction technical field, relates in particular to the geo-grid member that is applied in a kind of bridges and culverts back filling behind abutment.
Background technology
The bridges and culverts back filling behind abutment is an easy unheeded job, but usually is one of reason that has a strong impact on road, bridge functional performance.Step appearred in bridges and culverts works and roadbed junction after pavement construction was finished, vehicle by the time be easy to generate the phenomenon of soaring, engineering circle is commonly referred to " jumping car ".The reason that " jumping car " produces is complicated, comprehensive, its main cause is with base treatment, filling material and construction technology substantial connection to be arranged, solve bridge, contain the settlement after construction problem that platform is carried on the back, just must effectively handle substrate, and take correct working measure and construction method.
The utility model content
Technical problem to be solved in the utility model provides the geo-grid member that is applicable to the bridges and culverts platform back of the body, fills dank material simultaneously, thereby can well avoid " jumping car " phenomenon.
In order to address the above problem by the following technical solutions: a kind of geo-grid member that is applicable to the bridges and culverts platform back of the body, comprise geo-grid, the afterbody upper and lower faces of described geo-grid is respectively equipped with pressing plate and supporting steel plate, and the geo-grid afterbody is connected by the embedded bar of bolt fastener with bridges and culverts platform back.
Described pressing plate and supporting steel plate by the thick steel plate of 4mm make, width is 15mm.
Described pressing plate front face is welded on the embedded bar.
Described bolt fastener is not less than 50mm apart from the distance of geo-grid tail end, and bolt fastener comprises hexagon-headed bolt, packing ring and nut.
The end that described embedded bar is positioned at the bridges and culverts platform back of the body is provided with the reversed acanthoid projection.
The utility model is to have summed up national bridges and culverts platform back of the body processing scheme and improved and innovate, and by adopting dank material to add the utility model geo-grid member processing bridges and culverts back filling behind abutment, can avoid infiltrating the subgrade settlement that causes because of rainwater, also can optimize abutment zone whole stressed to substrate, can well avoid " jumping car " phenomenon.
The utility model is applicable to that roadbed is in soft foundation, roadbed is in the back filling behind abutment in high embankment zone and the backfill in general bridges and culverts platform back of the body zone.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of geo-grid member that is applicable to the bridges and culverts platform back of the body comprises geo-grid 1, be provided with above the afterbody of geo-grid 1 pressing plate 2, below be provided with supporting steel plate 3; Pressing plate 2 and supporting steel plate 3 by the thick steel plate of 4mm make, width is 15mm.The embedded bar 6 that geo-grid 1 afterbody is carried on the back on 5 by bolt fastener 4 and bridges and culverts platform is connected, and pressing plate front face is welded on the embedded bar.Bolt fastener comprises hexagon-headed bolt, packing ring and nut, and bolt passes embedded bar, pressing plate, geo-grid, supporting steel plate from top to bottom successively and locatees by nut.Bolt fastener is not less than 50mm apart from the distance of geo-grid tail end.The end that embedded bar 6 is positioned at the bridges and culverts platform back of the body 5 is provided with reversed acanthoid projection 7.
Use: substrate is handled, and general ground need reach corresponding bearing capacity of foundation soil, and soft foundation need be handled and after the assay was approved, carry out backfill again.During the bridges and culverts construction, need embedded bar in the bridges and culverts platform back of the body.After platform back of the body concrete reaches intensity, pressing plate is welded on the embedded bar, pressing plate, supporting steel plate and bolt fastener make bridges and culverts, geo-grid form one unidirectional geo-grid anchor connection; Equal backfill dank material (medium coarse sand) between the continuous two-layer geo-grid, and compacting.
