Description
Technical field
The present invention relates to ruggedized construction and the reinforcement means of a kind of underground structure, especially for improving shock resistance
The ruggedized construction of energy and method.
Background technology
In recent years, underground structure obtains at aspects such as the energy, traffic, communication, urban construction and defence engineerings
Extensively application.Along with the development of industrial and agricultural production and improving constantly of urbanization degree, underground structure important
Property is the most obvious.For a long time, it has been recognized that the negligible amounts of underground structure, underground structure anti-
Shock stability is better than again surface structures, and therefore, the harm that underground structure is caused by earthquake is little compared with surface structures.
But in recent years, along with the frequent generation of underground structure earthquake damage, it is each that underground structure anti-seismic problem is increasingly subject to the world
The great attention of state seismologist.Therefore, existing underground structure is carried out seismic hardening increasingly by weight
Depending on.
Summary of the invention
The present invention proposes a kind of underground structure seismic reinforcing structure and method, by arranging buffer layer, shock insulation wall,
And squeeze into anchor pole on the base plate and side plate of underground structure, the center pillar to underground structural seismic destructible simultaneously
Carry out consolidation process.Concrete technical scheme is as follows:
A kind of seismic reinforcing structure of underground structure, underground structure is positioned in surrounding soil, it is characterised in that:
Arranging some bolt anchorages between surrounding soil and underground structure, surrounding soil, the other end are stretched in anchor pole one end
It is fixed on underground structure.
Further: underground structure includes top board, side plate and base plate, it is provided with between side plate and surrounding soil and subtracts
Shake layer, anchor pole is between side plate and surrounding soil, and surrounding soil is stretched in anchor pole one end, and the other end is fixed on
Underground structure, middle through buffer layer.
Further: being provided with buffer layer between base plate and the lower section soil body of underground structure, buffer layer is Paulowniae
Lipid layer.
Further: the center pillar periphery of underground structure is provided with steel frame, between steel frame and center pillar, epoxy is filled out in filling
Mortar is cured as one.
Further: steel frame includes the angle steel being installed on center pillar corner, each angle steel is one by Plate Welding
The gap filling of body, steel plate and center pillar is filled out epoxy resin mortar and steel frame and center pillar is cured as one.
Further: the left-right and front-back any direction of underground structure is provided with shock insulation wall, underground is tied by shock insulation wall
The surrounding soil of structure and outside soil body isolation.
Further: anchor pole is hollow structure, and sidewall is provided with hole, is noted to anchor pole inner high voltage by hole
Enter cement mortar with fixing anchor bar and soil mass consolidation.
The formation flow process of the seismic reinforcing structure of above-mentioned underground structure, comprises the steps:
The first step: arrange buffer layer, at side plate and the sole periphery of underground structure, by boring height after boring
Pressure injection enters foamed resin, forms buffer layer；
Second step: utilize the boring injecting foamed resin, squeeze into anchor pole to inside soil body, notes to anchor pole inner high voltage
Slurry；
3rd step: reinforce the center pillar of underground structure, adhesivebonded bar method method for strengthening, angle steel is pasted onto center pillar
Four Angle Position, and with steel plate by integrally welded for four angle steel, and by the gap epoxy of steel plate Yu center pillar
Mortar fills and fills out；
4th step: at distance underground structure certain position, the shock insulation wall of certain depth is set.
After using ruggedized construction and the method for the present invention, the anti-seismic performance of underground structure has a characteristic that
1, between underground structure and surrounding soil, set buffer layer, make original soil-underground structure system become soil-
Buffer layer-underground structure system, is separated underground structure with the soil body by buffer layer, thus reduces and change ground
Shake the action intensity to structure and mode, to reach to reduce the purpose of vibration of underground structures.
2, by squeezing into anchor pole, carried out the grouting and reinforcing of the soil body by anchor tube simultaneously, formed by compacted soil and anchor
The joint reinforcement system that bar collectively constitutes, to improve stability in the large and the carrying of underground structure and surrounding soil
Ability.Can be applied in combination with grouting and reinforcing by bolt anchorage, can further improve underground structure from steady energy
Power and anti-seismic performance.
3, the position of destructible when the center pillar of underground structure is earthquake is understood according to conventional Earthquake damages, therefore
Use adhesivebonded bar method to reinforce original center pillar, make the transversely deforming pact by type steel skeleton of former pillar concrete
Bundle.Its advantage is, the sectional dimension of component expands few, but bearing power increase amplitude is big, and due in length and breadth
To the constraint of adhesivebonded bar, the ductility of component is made to improve a lot.
4, by squeezing into the diaphram wall of certain depth at distance underground structure certain position, so formed
The shock insulation wall of underground structure, can effectively stop the incoming of seismic wave, thus underground structure when reducing earthquake
Vibration.
