Abstract
A kind of freeze proof method for preventing skidding of wheels in severe cold area continuous beam straightway high trestle basis, excavates outward in basic surrounding, depth is adjusted flexibly close to cushion cap direction, it is ensured that do not destroy cushion cap.Uniformly excavate 2 slots, filled and process plate in slot in each direction.The circle of cystosepiment one that outline excavation edge is respectively provided with a thickness of 4cm, the external side of cystosepiment is with spilling one layer of salt fines on the film with glue.The material being combined by cement, flyash, clay, rubble, back-filling in layers compacting are filled between cystosepiment and basis.Bracket basis of the present invention gos deep under frozen soil, prevents frozen soil arch from bracket being made to move up the continuous beam straightway inclination that do not close up that will be constructed early period in winter, or form faulting of slab ends with curved section.Salt fines can reduce the freezing point of water, and cystosepiment energy is heat-insulated, blocks water, and cement, flyash and crushed stone clay filling layer and cystosepiment material are soft or hard suitable, all have the horizontal frost-heaving for alleviating ice, it is therefore prevented that bracket is shifted because surrounding frost-heave force is uneven, tilted.
Description
Technical field
The present invention relates to a kind of freeze proof method for preventing skidding of wheels in severe cold area continuous beam straightway high trestle basis to be specifically
Filled and process plate and cement, flyash and crushed stone clay complex material around basis prevent bracket basis uneven because of surrounding frost-heave force
It is even and shift.
Background technique
The teletostage that grand bridge is in belongs to extreme cold, and bridge 34#-37# pier is two-wire box structure continuous beam (32m+
48m+32m), 34#-37# pier pier shaft height 37m~39m is located in river shoal, and teletostage frost penetration reaches 1.8m, continuous beam straightway
Support system is steel pipe support, and 8 diameter 480mm steel-pipe weldings are respectively adopted, and basis uses long 9m × wide 6m × depth 2.5m steel
8 96cm × 96cm built-in fittings are arranged in reinforced concrete.
Summary of the invention
The object of the invention is that preventing frost heave from bracket basis being caused to deviate, propose one kind around basis using foam
Plate heat preservation, the method that cement, flyash, rubble, clay complex material are filled, this method construction technology is simple, practical, warp
It helps, efficiently.
The technical scheme is that a kind of freeze proof method for preventing skidding of wheels in severe cold area continuous beam straightway high trestle basis,
It is characterized in that: being carried out according to the following steps:
S1 excavates 1.6m in basic surrounding outward, and depth is 1.9m or so, and depth is adjusted flexibly close to cushion cap direction, it is ensured that
Do not destroy cushion cap.
S2 uniformly excavates in each direction 2 long 0.8m × wide 0.5m × depth 1.9m slot, filled and process plate in slot.
The circle of cystosepiment one that S3 outline excavation edge is respectively provided with a thickness of 4cm, film of the external side of cystosepiment with glue
On spill one layer of salt fines.
The material being combined by cement, flyash, clay, rubble is filled between S4 cystosepiment and basis, its ratio be water
Mud: flyash: clay: rubble=0.5:2.5:5:2, back-filling in layers compacting.Rubble can be replaced with cobblestone.
The present invention has the advantage that and good effect:
1, bracket basis gos deep under frozen soil, prevents frozen soil arch from bracket being made to move up the company that do not close up that early period in winter constructs
Continuous beam straightway inclination, or faulting of slab ends is formed with curved section.
2, salt fines can reduce the freezing point of water, and cystosepiment energy is heat-insulated, blocks water, cement, flyash and crushed stone clay filling layer and foam
It is suitable for all having the horizontal frost-heaving for alleviating ice that plate matter is soft or hard, it is therefore prevented that bracket occurs partially because surrounding frost-heave force is uneven
It moves, inclination.
Detailed description of the invention
Fig. 1 is the freeze proof anti-bias schematic diagram in especially big Surveillance of Continuous Beam straightway high trestle basis.

2. 2 long 0.8m × wide 0.5m × depth 1.9m slot, filled and process plate in slot are uniformly excavated in each direction.
3. the circle of cystosepiment one that outline excavation edge is respectively provided with a thickness of 4cm, film of the external side of cystosepiment with glue
On spill one layer of salt fines.
4. the material being combined by cement, flyash, clay, rubble (or cobblestone) is filled between cystosepiment and basis,
Its ratio be cement: flyash: clay: rubble (or cobblestone)=0.5:2.5:5:2, back-filling in layers compacting.
