Abstract
The utility model discloses a pavement inside dual-lane beam-type bridge end reinforced concrete framework abutment base, which comprises two parts including an abutment base and a retaining wall base. The abutment base and the retaining wall base are combined into a whole through two rectangular shallow piles; an inverted suspension plate base is arranged on one side on the two rectangular shallow piles, a suspension connecting beam parallel to the inverted suspension plate base is arranged on the other side, and one edge of the inverted suspension plate base is suspended outwards; a telescopic gap ranging from 1 cm to 2 cm is arranged between the suspension connecting beam and the inverted suspension plate base; two ends of the suspension connecting beam are suspended outwards, and the lower surfaces of the end heads of the suspended parts are supported on the round shallow piles; and a buttress lower strip-shaped base and a wing lug wall lower strip-shaped base are connected with the suspension connecting beam in the direction opposite to the suspension direction of the inverted suspension plate base, and used as the retaining wall base; the adoption of the base can save 30 percent of the construction cost of the general rectangular solid abutment base; the piles are shallow, and the construction is easy; and the base disperses the abutment centralized vertical axial load and horizontal force load, and belongs to the framework structure. Therefore, the construction cost is reduced.
Description
Technical field:
The utility model relates to a kind of road and bridge building unit, relates in particular to beam bridge end bar concrete frame abutment basis, two tracks in the sidewalk under a kind of reinforced concrete frame abutment that is applicable to bridge two ends, multispan footpath.
Background technology:
At present, along with the acceleration of development and national economy and Development of China's Urbanization, the Class I highway that extends in all direction, Class II highway, common road and speedway need be built, and increasing bridge needs to build, therefore, bridge to set up and build be the important engineering that highway connects.Bridge build the support that needs the bridge pier pier, the bridge pier pier needs on the tangible solid pier footing of seat, excellent its is the Base Design at end of the bridge two ends and builds even more important.No matter traditional bridge pier pile foundation is middle bridge pier pile foundation or two ends bridge pier pile foundation, its shape all is the rectangular solid pile foundation, during construction, and again cast after need deep-cutting the hole or boring tens meters.Promptly take a lot of work, time-consuming, cause wastage of material again; The inventor is devoted to the research and the design on bridge pier pier and pier basis always, successively declared multinomial patent to Patent Office of the People's Republic of China, and obtained patent right, its patent No. is: 200920090621, name is called: " two track beam bridge end bar concrete frame abutments in the sidewalk " promptly are wherein one, this patent primary structure is made up of frame type cushion cap and framed revetment two parts, the frame type cushion cap by one to down and on horizontal platform, two to down and on perpendicular platform and several to down and on outstanding binding beam form Heng Tai and two perpendicular platforms and be connected between two perpendicular platform two ends, the outstanding binding beam of in a row up and down several form one " in " the top plan view figure structure of font; Framed revetment is formed an open frame body of wall by linking wall, wing lug wall, attached wall wall, and frame type cushion cap, framed revetment are positioned on the same cushion cap basis; Though this pier is frame construction, construction costs can save 34.25%, and this pier still is based upon on traditional solid pier stylobate plinth, and therefore, the inventor thinks, is necessary to design a kind of cushion cap basis that cooperates therewith.
The utility model content:
In order to solve beam bridge two ends pier and retaining wall cushion cap foundation construction exists unscientific problem, the purpose of this utility model provides a kind of design science, can guarantee load, again can labor and material saving, beam bridge end bar concrete frame abutment basis, two tracks in the sidewalk of the easy row of construction party simultaneously.
The technical solution of the utility model realizes in the following manner:
Beam bridge end bar concrete frame abutment basis, two tracks in a kind of pavement, it is made up of pile foundation, retaining wall basis two parts, and its pile foundation, retaining wall basis are combined as a whole by two rectangular shallow stakes; Be provided with on the side above the two rectangular shallow stakes and be provided with the outstanding binding beam parallel with anti-hanging deck basis on an anti-hanging deck basis, the opposite side, one side outwards the encorbelmenting of anti-hanging deck basis; Be provided with 1-2 centimetre flexible gap between outstanding binding beam and the anti-hanging deck basis; Outwards encorbelment, encorbelment and be supported in the shallow stake of circle below the part termination in the two ends of outstanding binding beam; Be connected with the encorbelment outstanding binding beam of opposite direction direction of anti-hanging deck basis that strip foundation is used as the retaining wall basis under strip foundation under the counterfort wall, the wing lug wall;
Strip foundation is on two outstanding binding beams that are connected between the two shallow stakes under the counterfort wall, and strip foundation is on two outstanding binding beams that are connected outside the two shallow stakes under the wing lug wall; The termination of strip foundation is supported by rectangular shallow stake under the wing lug wall end under the two wing lug walls; Two shallow stakes of passive circle are arranged under the strip foundation under each counterfort wall.
Anti-hanging deck basis encorbelment the length of part be anti-hanging deck base thickness 5-6 doubly.
Strip foundation equates that with strip foundation left and right sides width under the wing lug wall two strip foundation vertical thicknesses are 1/5-1/6 of left and right sides width under the counterfort wall, under the wing lug wall front and back length of strip foundation be strip foundation under the counterfort wall front and back length 1/2.
Good effect of the present utility model is:
1, adopt this basis to save 35% than conventional rectangular solid pile foundation cost.
2, shallow, the easy construction of stake; Rectangular pile is the darkest to be two meter two, wide one meter two.
3, this basis has disperseed the bridge pier pier to concentrate vertical pivot to load and horizontal force load, belong to frame structure, thereby construction cost reduces.
4, under the counterfort wall under strip foundation and the wing lug wall strip foundation be to get final product under 60-80 centimetre or the frozen soil layer deeply, be easy to construction.
