Description
Technical field
The present invention relates to the earth structure in the civil engineering, the quake-proof coverage-type reinforced fill structure in particularly a kind of road (railway, highway) roadbed embankment engineering that can be used for the high-intensity earthquake area.
Background technology
Earth structure is ripe retaining engineering technology, because characteristics such as its economy, stable, aspect, compliance is strong are widely used in geotechnical engineering, construction work, traffic engineering and hydraulic engineering field.Industry such as traffic, water conservancy has successively been issued corresponding design specifications, and as " highway reinforced earth design specifications ", " railway bed retaining structure design specifications ", the design of static(al) reinforced earth bulkhead and construction are gradually ripe from putting into practice theory.
Traditional earth structure mainly is made of lacing wire, filler and panel, the lacing wire level, alternate, be arranged in the filler to stratification, utilize the frictional force between lacing wire and the filler to stablize the soil body, the effect of panel is to extrude from the side in order preventing to banket between lacing wire and to make structure have definite shape, beautifies the appearance and modeling of structure.A kind of novel reinforced earth bank protection structure is disclosed in the utility model patent manual of patent No. ZL200520029664.7, notice of authorization CN2851347Y, it comprises mask, mask basis, main muscle grid, cuts out grid, mantle typing sandbag etc. in advance, it is characterized in that the reinforcement body is by a plurality of equally distributed main muscle grids and the pre-grid two parts of cutting out, main muscle grid is returned bag, and on each main muscle grid, connect the pre-reinforcing bar composition of cutting out through the pitman level, in the main muscle grid that returns bag, be provided with mantle typing sandbag.Though this reinforced earth bank protection structure has the certain protection effect to mask; but owing to mask, interval rubble, main muscle grid are only connected by pre-sanction grid; when the structure occurred level is out of shape; the pre-grid of cutting out certainly will be subjected to big pressure; when structure generation vertical deformation, cause that easily the global failure of structure destroys.
At present, a large amount of highway construction circuits is crossed over the high-intensity earthquake area, especially the high-speed railway that Deformation control is had strict demand, the interaction under the earthquake motion load action between the resistance to overturning of earth structure and Deformation control, lacing wire and the panel become assistant officer's key issue to be solved.Find that by investigation the reinforced earth retaining wall structure collapses, but panel deformation is big, destruction is serious to ruggedized construction in the earthquake effect scope behind the Wenchuan earthquake.Therefore, at the earth structure that is positioned at the high-intensity earthquake area, for guaranteeing the stability of roadbed embankment engineering, the excessive deformation of control panel is necessary that panel, lacing wire and the connected mode between the two to earth structure improved.
Summary of the invention
Technical problem to be solved by this invention provides a kind of quake-proof coverage-type reinforced fill structure, has good resistance to overturning, the excessive deformation of control panel effectively, and strengthen the shock resistance of retaining wall, can be applicable to a retaining stabilization works in high-intensity earthquake area.
The technical solution adopted for the present invention to solve the technical problems is: quake-proof coverage-type reinforced fill structure of the present invention, the filler that comprises panel and the compacting of side placement in layers within it, and the rubble loaded filter that vertically is provided with, level in the filler, alternate, be furnished with main lacing wire to stratification, it is characterized in that: described panel is made of branch building block, the whole building block of vertically building by laying bricks or stones every row, wherein divide building block to constitute, described main lacing wire inflection parcel rubble loaded filter and interior building block by the outer building block that is combined into along the plate thickness direction, interior building block; Bonding surface between whole building block, outer building block, the interior building block also has vertical tenon riveting syndeton and/or vertical connected structure between outer building block and the whole building block except that imposing the cement mortar bonding, then have vertical connected structure between interior building block and the whole building block.
Be further to improve the resistance to overturning of structure, described main lacing wire is upper and lower to be laid with auxilliary lacing wire between two-layer, auxilliary lacing wire inflection parcel rubble loaded filter, and auxilliary lacing wire and main lacing wire are connected as one by connecting elements at its overlay segment.
The invention has the beneficial effects as follows, parcel has been carried out in main lacing wire handle at the panel place, make panel and reinforcement body stressed as a whole, weakened the pressure that mask bears greatly, strengthen structural integrity effectively, improved structural-load-carrying capacity; The reinforcement body is a flexible structure, adopt the parcel processing and the panel blockwork is interconnected by vertical tenon riveting syndeton and/or vertical connected structure, can not only adapt to the deformation requirement between reinforcement body and mask, also have good antidetonation shock attenuation performance, therefore can be applicable to a retaining stabilization works in high-intensity earthquake area.
