Abstract
The utility model discloses a rectangular pier suction basis of using in the weak soil layer, including pier, suction component and fixed component, the suction component go deep into in the weak soil stratum and to fix on the weak soil stratum through vacuum suction, the pier passes through fixed connector to be fixed on the suction component. Concretely, the suction component include a suction section of thick bamboo, during the weak soil stratum was goed deep into to the one end of a suction section of thick bamboo, the other end of a suction section of thick bamboo is sealed to set up fixed lid, the wash port is seted up to fixed covering, it forms vacuum negative pressure in the suction section of thick bamboo and fixes on the weak soil stratum to discharge to make through the muddy water mixture of wash port in with a suction section of thick bamboo, rethread fixed connector fixes the pier and covers fixed. Be fit for using in deep weak soil stratum, can undertake vertical load and horizontal loading simultaneously to guarantee that superstructure and pier structure are in the state of safety and stability.
Description
Technical field
The utility model belongs to building engineering field, the rectangle bridge specifically using in a kind of soft soil layerPier suction basis.
Background technology
Along with the development of China's economic construction and infrastructure construction, improve constantly in order to meetTransport need, many bridge spanning the seas or be about to build, as port Zhuhai and Macao bridge etc. Over strait largeIn the construction process of bridge, will inevitably run into seabed soft soil layer, give the construction band of pier footingCome difficult. In addition, weak soil has that intensity is low, water content is high, compressibility high, affects bridge pierThe resistance to overturning on basis.
Traditional axle pier foundation mainly adopts the pile foundation that the degree of depth is very large, and pile foundation is set on basement rock,The load producing to bear superstructure, but this conventional method is mainly applicable to seabed Soft Soil LayerThin place, for the geological conditions of deep soft soil, adopts the construction cost of conventional piles basic methodsVery high, also waste construction material simultaneously. Rectangular pier is conventional when bridge spanning the sea is built in recent yearsBridge pier form, also usually faces the execution conditions of deep soft soil layer, therefore needs exploitation a kind of specialFor the base form of the rectangular pier under deep soft soil layer condition.
Summary of the invention
For defect of the prior art and deficiency, it is a kind of specially for weak soil that the utility model providesRectangular pier suction basis in stratum, this basis can overcome traditional axle pier foundation effectively deepIn soft soil layer, be difficult to the problem of application, can bear vertical load and horizontal loading, to guarantee simultaneouslyBridge superstructure and the bridge pier structure state in safety and stability.
For achieving the above object, structure of the present utility model is:
The rectangular pier suction basis using in soft soil layer, comprises bridge pier, suction member and solidDetermine member, described suction member gos deep into being fixed on soft soil layer by pull of vacuum in soft soil layer,Bridge pier is fixed on suction member by fixed connecting piece.
Concrete, described suction member comprises suction tube, one end of suction tube is goed deep in soft soil layer,The other end sealing of suction tube arranges fixed cap, offers osculum on fixed cap, will inhale by osculumMud mixture in power cylinder is discharged formation negative pressure of vacuum in suction tube is fixed on soft soil layer, thenBy fixed connecting piece, bridge pier is fixed on fixed cap.
Preferably, described bridge pier is that cross section is the bridge pier of rectangle, and described suction member is transversalFace is the cartridge type parts of rectangle.
More specifically, described fixed connecting piece is bolt.
Further, described bridge pier is fixedly connected with the fixed cap co-axial seal of suction tube.
The utility model has the advantages that:
(1) the rectangular pier suction basis in soft soil layer of the present utility model utilizes the suction structure of tubularFirmly fixing by negative-pressure vacuum suction in the underwater soft soil layer of part, work progress simple and fast,Be highly suitable for while building bridge pier under water and use, the bridge pier of then needs being installed is fixed on the suction of hardOn power member, installation process simple and fast;
(2) the rectangular pier suction basis in soft soil layer of the present utility model, is adapted at Deep Thick Soft GroundIn stratum, apply, can bear vertical load and horizontal loading, thereby ensure bridge superstructure simultaneouslyAnd the state of bridge pier structure in safety and stability.
