Abstract
The present invention is operation highway soft soil roadbed bumping at bridge-head lower clapboard processing method, includes the following steps: the safety measure and mark of carrying out the current half range road excavation of half range roadbed；1.5~2.0m of half range roadbed depth, 20~30m long are excavated, supporting runway excavates roadbed side；Two rows are set by end of the bridge endLongitudinal pitch 100cm horizontal spacing 150cm long 10m drilled pile, sets two rows from end of the bridge endLongitudinal pitch 100cm horizontal spacing 150cm long 5m drilled pile；Half range roadbed bottom is excavated in leveling, is laid with 20cm thickness 20~30m long armoured concrete slab；Slag roadbed step backfill of delaying clearly first is carried out according to code requirement on armoured concrete slab, then carries out road surface, and open half range roadbed traffic；Other half range roadbed, open whole roadbed traffic are carried out according to the first step~the 5th step circulation.Foregoing invention use operation highway soft soil roadbed bumping at bridge-head lower clapboard processing method have it is easy for construction, it is economic and environment-friendly, fundamentally solve operation highway soft soil roadbed bumping at bridge-head.
Description
Technical field
The invention belongs to construction of the highway method field, has and be related to runing the processing of highway soft soil roadbed bumping at bridge-head lower clapboard
Method.
Background technique
Bumping at bridge-head is made due to the relative settlement or expansion joint destruction at highway end of the bridge and expansion joint (bridge approach)
Road surface longitudinal slope occur step cause vehicle by when generate jump the phenomenon that.There is different degrees of sink at back filling behind abutment in road surface
Drop fracture (sedimentation value is generally 10~30cm, and some is even more than 60cm), make vehicle by when generate and jump and impact, thus
Additional impact load is caused to bridges and culverts and road surface, so that driver and passenger is felt discomfort of jolting, or even vehicle is caused significantly to subtract
Speed, it is serious to can lead to traffic accident (especially vehicle mechanical accident).Run highway soft soil roadbed end of the bridge in China's Coastal Areas
It is more to jump vehicle phenomenon, operation traffic counting is larger at this stage, cannot suspend traffic, then existing roadbed is excavated in first half range part
Subgrade settlement is controlled with lower clapboard again, to achieve the purpose that solve operation highway soft soil roadbed bumping at bridge-head.
Summary of the invention
The present invention is easy to ignore roadbed using lower clapboard for existing operation highway soft soil roadbed bumping at bridge-head solution
Soft soil roadbed sinking and soft soil foundation relative stability relationship are controlled, lacks the deficiency of macro qualitative analysis control method, operation is provided
Highway soft soil roadbed bumping at bridge-head lower clapboard processing method.
The technical solution adopted by the present invention to solve the technical problems is: operation highway soft soil roadbed bumping at bridge-head lower clapboard
Processing method includes the following steps:
(1) technology and substance prepare before highway subgrade pavement is excavated:
Operation highway subgrade pavement knot is carried out in strict accordance with highway subgrade pavement design construction standard and traffic safety regulation
Technologies and the substance preparations such as structure safety prepare entire construction teams and subgrade and pavement substance in good state；
(2) safety measure and mark of the current half range road excavation of half range roadbed are carried out:
Security identifier is carried out in the current side of half range roadbed, and sends special messenger on duty, maintenance driving and construction safety；
(3) 1.5~2.0m of half range roadbed depth, 20~30m long are excavated, supporting runway excavates roadbed side, according to driving
Road excavates roadbed lateral stability, carries out gunite concrete or embedded steel board supporting, it is ensured that driving and construction safety；
(4) two rows are set by end of the bridge endLongitudinal pitch 100cm horizontal spacing 150cm long 10m drilled pile, from bridge
Head end sets two rowsLongitudinal pitch 100cm horizontal spacing 150cm long 5m drilled pile；
(5) half range roadbed bottom is excavated in leveling, is laid with 20cm thickness 20~30m long armoured concrete slab, is played control roadbed
The effect of deformation of bottom and average pressure；
(6) slag roadbed step backfill of delaying clearly first is carried out according to code requirement on armoured concrete slab, then carries out road surface, and
Open half range roadbed traffic；
(7) other half range roadbed, open whole roadbed traffic are carried out according to the first step~the 5th step circulation.
Beneficial effects of the present invention are mainly manifested in: the operation highway soft soil roadbed bumping at bridge-head lower clapboard that the present invention uses
Processing method have it is easy for construction, it is economic and environment-friendly, fundamentally solve operation highway soft soil roadbed bumping at bridge-head.
Detailed description of the invention
Fig. 1 is operation highway soft soil roadbed bumping at bridge-head lower clapboard processing schematic of the invention.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment 1: the technical solution adopted by the present invention to solve the technical problems is: operation highway soft soil roadbed end of the bridge is jumped
Vehicle lower clapboard processing method, includes the following steps:
(1) safety measure and mark of the current half range road excavation of half range roadbed are carried out；
(2) 1.5~2.0m of half range roadbed depth, 20~30m long are excavated, supporting runway excavates roadbed side；
(3) two rows are set by end of the bridge endLongitudinal pitch 100cm horizontal spacing 150cm long 10m drilled pile, from bridge
Head end sets two rowsLongitudinal pitch 100cm horizontal spacing 150cm long 5m drilled pile, is shown in Fig. 1；
(4) half range roadbed bottom is excavated in leveling, is laid with 20cm thickness 20~30m long armoured concrete slab, is played control roadbed
The effect of deformation of bottom and average pressure, is shown in Fig. 1；
(5) slag roadbed step backfill of delaying clearly first is carried out according to code requirement on armoured concrete slab, then carries out road surface, and
Open half range roadbed traffic, is shown in Fig. 1；
(6) other half range roadbed is carried out according to the first step~the 5th step circulation, Fig. 1 is shown in open whole roadbed traffic.
The operation highway soft soil roadbed bumping at bridge-head lower clapboard processing method that foregoing invention uses has easy for construction, economy
Environmental protection fundamentally solves operation highway soft soil roadbed bumping at bridge-head.
