Description
Technical field
This utility model belongs to civil construction slope supporting technical field, particularly relates to a kind of for embankment road
The U-shaped retaining structure of base.
Background technology
In rail track civil engineering field, reinforced earth retaining wall is a kind of gear propping up gear fill construction for circuit
Cob wall, as it is shown in figure 1, this reinforced earth retaining wall is generally arranged, by constructing soil in the lateral symmetry of foundation ditch
Body 1, many lacing wires 2, basis 3, shingle nail 4 and cap stone 5 form；Wherein basis 3 is along circuit extension side
To being arranged on side, foundation ditch bottom surface；The lower end of shingle nail 4 is fixed on basis 3, and cap stone 5 is then arranged on wall
The upper end of panel 4；Many lacing wire 2 standoff distances are horizontally disposed with, and one end is connected to the interior of shingle nail 4
On side；Fill the soil body 1 to be filled in the space between the shingle nail 4 that two sides is oppositely arranged.It is dependent on
Fill the frictional force between the soil body 1 and lacing wire 2 to balance the horizontal earth pressure that shingle nail 4 is born, to protect
Hold stablizing within reinforced earth retaining wall, and with basis 3, shingle nail 4, cap stone 5, lacing wire 2 and constructing soil
The composite construction of body 1 composition and form cob wall, be positioned at the soil body 1 that fills of lacing wire 2 afterbody with opposing and produced
Soil pressure, to keep the external stabilization of reinforced earth retaining wall, thus ensure that the entirety of reinforced earth retaining wall
Stability.
But, the reinforced earth retaining wall of this structure be only applicable to I level, II grade of railway typically area, 8 degree with
The curb location of lower earthquake areas and embankment location, owing to the height of this reinforced earth retaining wall is at I level main line
On be preferably greater than 10m, therefore its gear limited height；It addition, arrange this reinforced earth retaining wall at curb
Time, wall top is preferably located at the elevation of surface layer of subgrade bed bottom surface, additionally, reinforced earth retaining wall need to arrange basis, therefore
It is both needed to take up an area, so the requirement saved the area as far as possible can not be met；And more than 8 degree area, have
Strong corrosion environment should not use, and more should apply cautiously under the conditions of immersion.
Cantilevered and counterfort wall are two kinds of reinforced concrete retaining walls, it is adaptable to building stones lack and ground
The embankment location that bearing capacity is relatively low.As in figure 2 it is shown, cantilever retaining wall generally sets in the lateral symmetry of foundation ditch
Put, by armstand 6, toe of wall plate 7, tenon 8, wall heel slab 9 with fill the soil body 10 and form；Its neutral arm 6 edge
Circuit bearing of trend is vertically set on side, foundation ditch bottom surface；Toe of wall plate 7, tenon 8 and wall heel slab 9 are respectively from vertical
The lower end of arm 6 is outwards, downwardly and inwardly formed；Fill the soil body 10 and be filled in the armstand 6 that two sides is oppositely arranged
Between space in.This cantilever retaining wall is dependent on armstand 6 toe of wall plate 7, tenon 8, wall heel slab 9 groups
The wall body deadweight become and wall heel slab more than 9 fill the gravity of the soil body 10 (including load) and maintain the steady of retaining wall
Fixed.
As it is shown on figure 3, counterfort wall is generally arranged in the lateral symmetry of foundation ditch, its structure and cantilevered
The structure of retaining wall is essentially identical, and unique except for the difference that it also includes that counterfort 11, the two ends of counterfort 11 connect respectively
It is connected between the upper end of armstand 6 and the outer end of wall heel slab 9, and counterfort 11 is also subjected to a part of wall behind
Soil pressure.
But either cantilevered or counterfort wall, a gear is the most limited, cantilever retaining wall height
Not being preferably greater than 6m, counterfort wall height is not preferably greater than 10m；Additionally, cantilevered and counterfort wall
It is both needed to arrange wall location plate 7, therefore needs to take up an area, so the requirement saved the area as far as possible can not be met；And counterfort
Formula retaining wall should not make in Unfavorable Conditions or site ground motion peak accelerator 0.2g and above area
With.
Summary of the invention
In order to solve the problems referred to above, the purpose of this utility model is to provide a kind of U-shaped for filled-up ground
Retaining structure.
In order to achieve the above object, the U-shaped retaining structure for filled-up ground that this utility model provides includes U
Shape groove, many bracket contact net columns and fill the soil body；Wherein U-lag is arranged on base along circuit bearing of trend
In hole, for reinforced concrete structure, being made up of with twice abutment wall base plate, the lateral surface of abutment wall is vertical,
Medial surface top is vertical, and medial surface bottom is inclined-plane, and the biggest the closer to the thickness of base plate abutment wall；
Bracket contact net column is reinforced concrete structure, and many bracket contact net column standoff distances are vertically set on
The upper end of abutment wall；Fill the soil body to be filled in the inner space of U-lag.
The height on described abutment wall top fills soil body top with being arranged on and is positioned at the lateral sulcus degree of depth of circuit both sides
Identical.
Angle between described abutment wall lower inside surface and base plate is 65 degree.
The cross-sectional shape a size of 700mm × 860mm of described bracket contact net column, it is embedded with lower margin
Bolt and fixing steel plate, height is not less than pre-embedded bolt anchorage length, fixing steel plate and bracket contact net column
The end face of 13 flushes.
The U-shaped retaining structure for filled-up ground that this utility model provides has the advantages that to strive
Take outside ground flap hem width degree, reduce occupation of land to greatest extent, thus realize reducing land used, reduce remove or
The purpose do not removed.Simple in construction, easy construction and construction cost are low, therefore at railroad embankment retaining engineering
