Description
Technical field
The invention belongs to the technical field that the shake of concrete antiknock crashworthiness is reinforced, relate to the reinforcement means of a kind of metro station tunnel and bridge construction along the line particularly.
Background technology
Subway has become the main traffic instrument of big and medium-sized cities, but station, crowded district also becomes the key object of explosive attack, and its fire probability is also larger.Meanwhile, along with urban traffic amount increases gradually, Traffic Collision Frequent Accidents, hits shake badly broken especially to road and bridge concrete structure, and recovers difficulty.
At present, metro station tunnel disaster prevention aspect mainly takes as strengthened the measures such as safety check, design safety passage or shelter, enhancing ventilation equipment, strengthening device inspection and maintenance; Bridge crashworthiness shake reinforcing aspect, mainly through increasing beam column size or concrete reinforcement mod sum label, to improve strength of reinforced concrete.Reinforcement means in the past, by increasing the way of human and material resources and financial resources, strengthening structural strength and durability, considerably increasing maintenance cost simultaneously, also significantly add concrete own wt, unfavorable to structural entity safety.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, the reinforcement means of a kind of metro station tunnel and bridge construction along the line is provided, it is simple to operate, convenience of drawing materials, energy-conserving and environment-protective, with low cost, safe and reliable, elegant in appearance, be suitable for the fire-and explosion-proof crashworthiness reinforcing of City Subway Station tunnel and Concrete Bridge Structures along the line.
Technical solution of the present invention is: the reinforcement means of this metro station tunnel and bridge construction along the line, comprises the following steps:
(1) clear up concrete surface, make it clean;
(2) according to concrete intensity, dimensional requirement, bandage material, wrapping method and parcel form is determined, thus wrapping concrete;
(3) at the outer placing porous metal clip core building block of bandage, and porous metals sandwich structure unit is utilized together with bolton with concrete;
(4) at the outer brushing exterior wall coating material of porous metals sandwich structure unit.
Present invention employs bandaging concrete and play reinforcement antihunt action; Outer lining porous metals sandwich structure unit and play antiknock and impact resistance effect; Avoid quick-fried crucial carrying destroying concrete structure when hitting generation; Outer brushing exterior wall coating material covers inner concrete and plays attractive, decorative effect; So it is simple to operate relative to prior art, convenience of drawing materials, energy-conserving and environment-protective, with low cost, safe and reliable, elegant in appearance, be suitable for the fire-and explosion-proof crashworthiness reinforcing of City Subway Station tunnel and Concrete Bridge Structures along the line.

Detailed description of the invention
As shown in Figure 1-2, the reinforcement means of this metro station tunnel and bridge construction along the line, comprises the following steps:
(1) clear up concrete 1 surface, make it clean;
(2) according to concrete intensity, dimensional requirement, bandage 2 material, wrapping method and parcel form is determined, thus wrapping concrete;
(3) at the outer placing porous metal clip core building block 3 of bandage, and bolt 4 is utilized to tighten together porous metals sandwich structure unit and concrete;
(4) at the outer brushing exterior wall coating material 5 of porous metals sandwich structure unit.
Present invention employs bandaging concrete and play reinforcement antihunt action; Outer lining porous metals sandwich structure unit and play antiknock and impact resistance effect; Avoid quick-fried crucial carrying destroying concrete structure when hitting generation; Outer brushing exterior wall coating material covers inner concrete and plays attractive, decorative effect; So it is simple to operate relative to prior art, convenience of drawing materials, energy-conserving and environment-protective, with low cost, safe and reliable, elegant in appearance, be suitable for the fire-and explosion-proof crashworthiness reinforcing of City Subway Station tunnel and Concrete Bridge Structures along the line.
In addition, also step is comprised between described step (1) and (2): at concrete surface brush cementing agent.Bandage and concrete can be made like this to fix securely.
Further, described cementing agent is high-strength glue.
In addition, bandage material described in step (2) is plain edition, gluing type, nylon type or polyester fiber shaped material.Certain bandage material is not limited to above, other all kinds of chemistry or macromolecular material.
By testing without the concrete strength detection of bandage concrete, nylon type bandage concrete and gluing type bandage, test result explanation, as shown in Figure 3, sharply reduce without numerical value after bandage concrete load-displacement curves upward peak, after peak value, the slope of curve is comparatively large, strong without bandage Brittleness of Concrete, easily compresses brittle fracture, load-displacement curves and offset axis closed area little, total energy absorption is little; As shown in Figure 4, after nylon type bandage concrete load-displacement curves upward peak, numerical value reduces more slow, and after peak value, the slope of curve is less, nylon type bandage concrete compressive ductility increases, brittle fracture feature is less, and load-displacement curves and offset axis closed area are comparatively large, and total energy absorption is larger; As shown in Figure 5, after gluing type bandage concrete load-displacement curves upward peak, numerical value reduces mild, and after peak value, the slope of curve is little, and gluing type bandage concrete compressive ductility is comparatively strong, and greatly, total energy absorption is large for load-displacement curves and offset axis closed area.
After adopting nylon type bandage and the bandaging of gluing type, concrete compressive ductility strengthens, and energy absorption entirety increases comparatively large, for concrete structure design theory and anti-seismic performance raising effect larger.
In addition, described in step (2), wrapping method comprises loop method, snakelike method, spirality method, spiral reverse turn and 8-shaped method.Other wrapping method can certainly be adopted.
In addition, described in step (2), parcel form comprises: the winding of spiral winding, lamination, cross winding, orthogonal winding.Other parcel form can certainly be adopted.
In addition, the thickness of the porous metals sandwich structure unit in described step (3) is 5cm-20cm, and sandwich material is foamed aluminium, aluminium silicon or aluminium alloys, and the inside of sandwich structure is the form of structure of diamond crossing, asperity, ripple glaze or special-shaped line.Other form of structure can certainly be adopted.
In addition, the exterior wall coating material in described step (4) is fireproof paint, and color, the thickness of fireproof paint need to determine according to scene, and fire endurance reaches 3 hours.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong to the protection domain of technical solution of the present invention.
