Abstract
The utility model discloses a quick polyurethane foam backfilling body for roadbed missing, and aims to provide a roadbed missing backfilling body which can quickly repair a missing roadbed and prevent the backfilling body from sinking along with the changes of time and environments. The polyurethane foam quick backfilling body for the roadbed missing comprises backfilling aggregates; polyurethane foams are filled in gaps of the backfilling aggregates to form a concrete structure including the backfilling aggregates and the polyurethane foams. The backfilling aggregates consist of broken stones or a mixture of broken concrete and the broken stones. By the backfilling body provided by the utility model, the missing roadbed can be repaired quickly; the statute limitations of mechanical compaction, consolidation and stabilization are broken; the backfilling speed is high; the efficiency of disaster relief can be improved; the normal production and living order is recovered quickly. The backfilling body disclosed by the utility model can not sink along with the changes of time and environmental conditions; the chronicity and the reliability of road service are improved; the temporary emergency use after repairing and the long-term use after disasters (wars) are coordinated.
Description
Technical field
The utility model relates to a kind of roadbed disappearance and adopts the quick backfill liptinite of polyurethane foam.
Background technology
Since natural calamities such as earthquake, tsunami, flood wreck with war in the strike of high-tech precision guided weapon, highway, airport etc. unavoidably damages and injures, and seriously restricts and influence the performance of basic function.Under the destruction of natural calamities such as flood, earthquake and tsunami, road structure disappearance is often for large tracts of land is sagging, landslide, loss etc.; Under the high-tech precision guided weapon hit, the road structure disappearance often was the big scale of construction, highly dense crater.Need for the disappearance of roadbed that backfill is fixed repairs.Present backfill concretion technology generally is back-filling in layers and rolls real or compacting, wastes time and energy, and causes and repairs difficulty, causes traffic to be interrupted for a long time.And owing to be subjected to rolling the restriction that real or compacting influences the degree of depth, in use often because of time and environmental change depression takes place inevitably, cause repairing not put things right once and for all.
The utility model content
The purpose of this utility model is the technological deficiency that exists in the prior art in order to overcome, and a kind of disappearance roadbed of can repairing fast is provided, and keeps the backfill body not in time with environmental change and the roadbed of depression disappearance backfill body.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of roadbed disappearance is characterized in that with the quick backfill body of polyurethane foam, comprises that backfill gathers materials, and is filled with polyurethane foaming body in the space that described backfill is gathered materials, and forms the concrete structure that described backfill is gathered materials and is mingled with described polyurethane foaming body.
Described backfill is gathered materials and is mixed composition with rubble for rubble or broken concrete.
The particle diameter of described rubble is 30-50mm.
The utlity model has following beneficial effect:
1, backfill body of the present utility model can be repaired the disappearance roadbed fast, has broken through the timeliness restriction of mechanical ramming stabilization by consolidation, and backfill speed is fast, can improve the efficient of fighting calamities and providing relief, and recovers normal rapidly and produces and the life order.
2, backfill body of the present utility model has improved chronicity and the reliability of road service not in time with changes in environmental conditions and depression, and make the repairing back interim emergent use with the long-term use in calamity (war) back harmonious.
Description of drawings
Figure 1 shows that the utility model roadbed lacks the schematic diagram with the quick backfill body of polyurethane foam.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Figure 1 shows that the utility model road roadbed lacks the schematic diagram with the quick backfill body of polyurethane foam, comprise that backfill gathers materials 1, be filled with polyurethane foaming body 2 in the space that described backfill is gathered materials, form described backfill 1 concrete structure that is mingled with described polyurethane foaming body 2 that gathers materials.Described backfill is gathered materials and 1 is mixed composition with rubble for rubble or broken concrete.Use particle diameter to gather materials as backfill as the rubble of 30-50mm in the present embodiment.Wherein, described polyurethane foaming body adopts conventional dual-component polyurethane expanding foam solution foaming to form.A component in the two component polyurethane expanding foam solution can form by the cross-linking reaction self-polymerization for toluene di-isocyanate(TDI) or '-diphenylmethane diisocyanate, the B component is the multicomponent mixture of being made up of hydroxyl polyether resin, epoxy resin, intensity reinforcing agent and kicker, the coefficient of foaming of described dual-component polyurethane expanding foam solution is 2.5-3.0 times, and the temperature before the described dual-component polyurethane expanding foam solution perfusion is 30-45 ℃.
A component and the B component that will be arranged in different material-storage jars are heated to respectively about 30-45 ℃, and stir, again after filtration, by two measuring pumps A component and B component are transported to separately dedicated pouring head respectively afterwards, A component and B component be through separately professional pouring head after evenly ejection mixes at a high speed, is filled in the space that backfill gathers materials.The dual-component polyurethane expanding foam solution is full and uniform enters into each space, form hard bubble after, form the concrete structure that backfill is gathered materials and is mingled with polyurethane foaming body.The interior roadbed to formation of stable back 2h that foams under the normal temperature lacks quick backfill body and carries out physical property detection, rupture strength: 2.0-4.0MPa; Impervious: 2.0-1.0MPa, leakproof; Foaming liptinite unconfined compression strength: 4.0-8.0MPa; Modulus of elasticity: 2.0 * 10
3-4.0 * 10
3MPa; Adhesion strength: 8.0-10.0MPa; Heat resistance:＞100 ℃, satisfy the mechanical performance of roadbed requirement.Foaming was stablized in 5 hours not to be had cracking and peels off.
