Structure, barricade pours the upper surface for being fixed on capping beam, and the soil body that the upper end of barricade is not less than between high ferro roadbed and foundation ditch is high
Degree.
Being excavated on the soil body between further described high ferro roadbed and foundation ditch has gutter；Described gutter sidepiece
Barricade is fitted in towards on the wall of high ferro roadbed side, the upper end in gutter does not protrude from soil body surface.
Concrete hardening layer has been poured in soil body surface between further described high ferro roadbed and foundation ditch；Described
Concrete hardening layer one end is fixed on the sidepiece in gutter, and the other end extends to high ferro roadbed.
Further described capping beam maintains an equal level with the inner support in the top in foundation pit supporting construction；Described interior branch
The end of support is fixedly connected with capping beam sidepiece.
Further described barricade upper end is provided with guardrail.
Advantage of the present utility model has：1st, the utility model, can be to foundation ditch by setting barrier wall structure in margin of foundation pit
The soil body between high ferro roadbed is provided a supporting role, it is to avoid the generation for the high ferro Roadbed Deformation problem that soil body slipping is caused；
2nd, the utility model is by setting barrier wall structure, it is to avoid soil body slipping is entered in foundation ditch, solves traditional base
Hole support pattern needs to be excavated into slope structure to the soil body of margin of foundation pit, reduces earthwork excavated volume, reduces construction
Difficulty；
3rd, the utility model can strengthen the soil body by further being hardened to the soil body between foundation ditch and high ferro roadbed
Rigidity, it is to avoid because high ferro run cause the soil body extruding influence high ferro roadbed stability.
The utility model reduces earth excavation at slope, reduces the disturbance of the destruction to high ferro surrounding soil, reduces height
Railway base, abutment, pipeline deformation, are easy to carry out high-frequency monitoring to support pile.Utility model support cost is low, it is convenient to construct,
By field monitoring, high ferro protecting effect is obvious, with very strong practicality.
Brief description of the drawings
Fig. 1：Structural representation of the present utility model；
1-barricade, 2-guardrail, 3-monitoring point for displacement, 4-gutter, 5-concrete hardening layer, 6-original design slope
Face, 7-reduce and excavate the soil body, 8-capping beam, 9-support pile, 10-inner support.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Such as Fig. 1, a kind of band barricade capping beam for reducing high ferro Roadbed Deformation, the capping beam 8 of the present embodiment is close to base
The reinforced beam poured in the horizontal direction of pit edge, capping beam 8 is located at the soil body surface between foundation ditch and high ferro roadbed
The difficulty of construction of foundation pit supporting construction can be greatly lowered in lower section, the height of reduction capping beam 8, also reduce later stage supporting knot
The difficulty of structure dismounting work.
Capping beam 8 is fixed on the upper end of support pile 9, and capping beam 8 maintains an equal level with the inner support 10 in uppermost position, beared down on one
Beam 8 is fixedly connected with the end of inner support 10.The upper end of capping beam 8 has poured barricade 1, and the upper end of barricade 1 is provided with guardrail.Barricade
1 is used to stop the armored concrete knot that the soil body between high ferro roadbed and foundation ditch is moved to foundation ditch side to be fixed on margin of foundation pit
Structure, barricade 1 pours the upper end for being fixed on capping beam 8.The capping beam 8 and barricade 9 of the present embodiment are reinforced concrete structure, are led to
Cross and be welded to connect the framework of steel reinforcement in capping beam 8 with the framework of steel reinforcement in barricade 9, by increasing capacitance it is possible to increase both bonding strengths.
Wherein, as shown in figure 1, the upper end of barricade 1 is not less than the soil body surface between high ferro roadbed and foundation ditch, in order to reduce
The construction cost and difficulty of barricade 1, upper end and the soil body surface of the barricade 1 of the present embodiment maintain an equal level.The upper end of barricade 1 is provided with position
Monitoring point 3 is moved, for monitoring the change of high ferro roadbed.Positional distance soil body surface is more closely, can become apparent from accurately herein
Monitoring high ferro roadbed change.
Barricade 1 one is to reduce earthwork excavated volume, it is to avoid traditional mode need to excavate on the soil body it is domatic, such as Fig. 1 institutes
Show, it is to reduce to excavate the soil body 7 that original, which designs the domatic part between barricade 1, by setting barricade 1 to reduce the excavation of the earthwork
Amount, two be that can strengthen the rigidity of the soil body, it is to avoid the security of soil body moving influence high ferro roadbed.
During practical application, the influence in order to avoid rainfall to the soil body, soil of the present embodiment between high ferro roadbed and foundation ditch
Being excavated on body has a gutter 4, and the sidepiece of gutter 4 is fitted in barricade 1 towards on the wall of high ferro roadbed side, gutter 4 it is upper
End does not protrude from soil body surface.Precipitation is collected by gutter 4 and discharged, and will not produce influence to the soil body.
In addition, the present embodiment has poured concrete hardening layer 5 in the soil body surface also between high ferro roadbed and foundation ditch, mix
Solidifying soil hardened layer 5 one end is fixed on the sidepiece in gutter 4, and the other end extends to high ferro roadbed.Concrete hardening layer 5 further increases
The strong rigidity of the soil body, reduces the amount of contraction of the soil body, reduces the deformation quantity of high ferro roadbed, improve the safety of high ferro roadbed
Property.
During practice of construction, when pouring capping beam 8, the steelframe skeleton in capping beam 8 is exposed into a part outside capping beam 8
Side, when pouring barricade 1, the steelframe skeleton in barricade 1 and the framework of steel reinforcement that exposes on capping beam 8 is welded to connect, then started
Barricade 1 is poured, the concrete structure for making barricade 1 stable with the formation of capping beam 8.
Guardrail 2 is installed by expansion bolt, it is easy to disassemble to install, excavated on the soil body between barricade 1 and high ferro roadbed
Gutter 4, then casting concrete hardened layer 5 carries out cure process to soil body surface on the soil body, completes construction.
