Description

Anti-settling device of highway subgrade

Technical field

The utility model is related to road foundation, particularly a kind of Anti-settling device of highway subgrade.

Background technology

In the construction project of highway, the processing to highway subgrade is extremely crucial, is also the difficult point in construction of the highway, Often have the road that large-scale or heavy vehicle passes through for some, or often meet with the section that heavy rain washes away, heavy vehicle or Heavy rain can produce certain damage to roadbed, roadbed can be made to produce sedimentation, particularly in the joint of road and bridge, due to bridge Subgrade settlement degree of the beam with end of the bridge two ends in itself is inconsistent, and the sedimentation degree of the roadbed at end of the bridge two ends is more than bridge heavy in itself Drop, so, vehicle can produce the situation of " bumping at bridge-head ", be that the form of vehicle causes certain safety hidden when by end of the bridge Suffer from.

The content of the invention

For above-mentioned situation, to overcome the defect of prior art, the purpose of the utility model is just to provide a kind of highway road Base anti-settling facility, can effectively solve the subgrade settlement of bridge body and bridge head inconsistent causes vehicle traveling to there is peace The problem of full hidden danger.

Its technical scheme solved is, including soil layer and sand stone layer, has sand stone layer on soil layer, coagulation is arranged at the top of sand stone layer There is cavity in soil block, concrete block, the upper end of cavity is opening shape, and the upper surface of concrete block has on cover plate, the bottom surface of cavity Having on multiple blind holes, the lower surface of cover plate has multiple fixed columns, and fixed column is placed in cavity, and the lower surface of fixed column is placed in blind hole Interior, having on the outer edge surface of fixed column has what is connected with the bottom surface of blind hole on multiple ring-type fixing plates being arranged above and below, concrete block Having been piled with rhone, cavity has multiple stone putting holes on stone, cover plate.

The utility model structure is novel, reusable, and draining is convenient, and effectively the pressure of heavy vehicle can be delayed Punching, can greatly reduce the settling amount of Bridgehead by Blastig.

Embodiment

Embodiment of the present utility model is described in further details below in conjunction with accompanying drawing.

Provided by Fig. 1 to Fig. 4, the utility model includes having sand stone layer 2 on soil layer and sand stone layer, soil layer 1, sand stone layer 2 Top, which has, cavity 4 in concrete block 3, concrete block 3, the upper end of cavity 4 is opening shape, and there is lid the upper surface of concrete block 3 Having on plate 5, the bottom surface of cavity 4 has multiple fixed columns 7 on multiple blind holes 6, the lower surface of cover plate 5, fixed column 7 is placed in cavity 4, The lower surface of fixed column 7 is placed in blind hole 6, there is multiple ring-type fixing plates 8 being arranged above and below, coagulation on the outer edge surface of fixed column 7 Having to have piled with the rhone 9 that the bottom surface with blind hole 6 is connected, cavity 4 on soil block 3 has multiple stones to place on stone 10, cover plate 5 Hole 11.

Horizontal positioned has the pressing plate being sleeved in fixed column 7 in stability during in order to ensure to use, described cavity 4 12, the support bar 13 for being placed in the bottom of pressing plate 12 is interspersed with fixed column 7, pressing plate 12 is fixed in fixed column 7 by support bar 13, pressure There is stone putting hole on plate 12.

In order to ensure the lower surface of the fixed column 7 on the bearing capacity of cover plate 5, described cover plate 5 and blind hole 6 bottom surface it Between have gap.

Multiple ring-type fixing plates 8 in described fixed column 7 are placed in blind hole 6, and ring-type fixing plate 8 is through helicitic texture spinning It is convenient to install and reuse in fixed column 7.

Equipped with many montants 14 on the lower surface of described concrete block 3, montant 14 runs through under sand stone layer 2, montant 14 In termination insertion soil layer 1, concrete block 3 is fixed.

The utility model places sand stone layer 2 on soil layer 1, and placed in sand stone layer has in concrete block 3, concrete block 3 Fixed column 7 on cavity, cover plate 5 is placed in cavity 4 and inserted in blind hole 6, puts stone 10 through the stone putting hole 11 on cover plate 5 Put in the cavity 4 of concrete block 3, stone 10 is full of whole cavity 4, due to there is multiple ring-type fixing plates 8 in fixed column 7, Cover plate 5 is firmly secured on concrete block 3 by stone 10 through ring-type fixing plate 8, and when running into when raining heavyly, rainwater can be introduced into chamber In body 4, cavity is first collected to rainwater, stone has temporary transient water-holding capacity, reach the work for substantially reducing rain-impact power With the outside then through the discharge concrete block 3 of rhone 9；When there is heavy goods vehicles amount by cover plate 5, due under cover plate 5 by stone There is supporting role to it, simultaneously because having gap between the lower surface of the fixed column 7 on cover plate 5 and the bottom surface of blind hole 6, also to lid The certain deflection of plate, cover plate has certain deformation space when being pressurized, in deformation, the pressure that stone is born to cover plate simultaneously Power slowly receive and discharge, it is ensured that the security of cover plate.

In order to further ensure to be set with pressing plate in stability that cover plate is fixed on concrete block 3, fixed column 7 12, also there is stone the top of pressing plate, and a downward pressure is produced to fixed column through pressing plate.

When the utility model is installed, first pressing plate 12 is fixed in fixed column 7 through support bar 13, it is then that multiple annulars are solid The spinning of fixed board 8 lifts cover plate 5, cover plate, fixed column and pressing plate is together placed on concrete block 3 afterwards in fixed column 7, Laggard cover plate on stone putting hole 11 and pressing plate on stone putting hole, in the cavity that stone is placed on to concrete block 3, The fixation to cover plate 5 is completed, when needing to change or repairing, cover plate is sling.

The upper surface of the utility model cover plate is road surface, and cover plate and concrete block 3 together can be timely by substantial amounts of rain Water is collected, and the pressure of heavy vehicle can be born again, and the pressure-bearing pressure of sand stone layer and soil layer is alleviated indirectly, end of the bridge is reduced The sedimentation degree of the roadbed at two ends.
