Abstract
A road and bridge shock absorption device is formed by an upper-layer foundation pile, an anchored pile, a superficial layer pile, a sliding steel girder, deep-layer pile summary tops and deep-layer foundation piles. The deep-layer foundation piles are basic piles perpendicularly arranged on deep-layer underground and can be arranged in drilling manner; each three deep-layer foundation piles form a small group; each four small groups form a large group and can serve as a deep-layer foundation of an exposed pier; the deep-layer pile summary tops are arranged at the top ends of each three deep-layer foundation piles; the deep-layer pile summary tops linked integrally are arranged at the upper ends of two groups of the deep-layer foundation piles in the middle; the sliding steel girder is arranged on the deep-layer pile summary tops; the superficial layer foundation pile is arranged on the sliding steel girder; the anchored pile is used for connecting the centered deep-layer pile summary tops, the sliding steel girder and the superficial foundation pile into a whole; and the upper-layer foundation pile is arranged on the superficial layer foundation pile, namely a foundation pile above ground. The road and bridge shock absorption device has simple integral structure and convenient operation and use, and improves shock absorption effect of roads and bridges as the sliding steel girder is arranged between the deep-layer foundation piles and the superficial layer foundation pile.
Description
Technical field:
The utility model relates to the highway bridge servicing unit, relates in particular to a kind of road and bridge damping device.
Background technology:
The seismic design of road and bridge generally is a requirement of strength of considering whole antidetonation, designs and constructs according to the seismic design of country and job specfication.This road and bridge, comprise road bridge and railway bridge, under the situation that earthquake takes place, seismic wave is by soil layer and rock stratum the basis formation of road and bridge to be impacted, and then directly impact force is passed to superstructure, the consequent internal stress of superstructure, react on the basis of road and bridge again, therefore, road and bridge the basis Intensity Design, should be the reaction force that seismic forces adds the top structure.If calculate like this and design, its construction drops into can be very big, and final anti seismic efficiency is unsatisfactory.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provide a kind of road and bridge damping device, avoid the theory of rigid impact with soft to firmly, reduce the overall weight of road and bridge, reduce construction volume, improve the actual effect of antidetonation.
A kind of road and bridge described in the utility model damping device, include upper strata foundation pile, anchor pile, shallow-layer foundation pile, slip girder steel, the deep layer stake gathers the top and the deep layer foundation pile is formed.Said deep layer foundation pile is to be vertically set on the underground foundation pile of deep layer, can form be set with boring.If taking an examination to consider to be arranged on, the design specifications height of road and bridge, the following bottom of deep layer foundation pile stablize on the face of rock stratum.Per three deep layer foundation piles are a group, and per four groups are a big group, can be used as a deep foundation that exposes bridge pier.Top on said per three deep layer foundation piles, be provided with the deep layer stake and gather the top, middle two groups deep layer foundation pile upper end, the deep layer stake of being arranged to gang gathers the top, gather above the top in said deep layer stake, be provided with the slip girder steel, above the slip girder steel, be provided with the shallow-layer foundation pile again, with anchor pile deep layer stake placed in the middle gathered top, slip girder steel and shallow-layer foundation pile and link together.On said shallow-layer foundation pile, the upper strata foundation pile is set again, just the above foundation pile in ground.
A kind of road and bridge described in the utility model damping device, overall structure is simple, and is easy for operation, between said deep layer foundation pile and shallow-layer foundation pile, is provided with the slip girder steel, as the device that receives earthquake shock power, and improved the anti seismic efficiency of road and bridge with this.
Description of drawings:
Accompanying drawing 1 is the structural representation of a kind of road and bridge described in the utility model damping device.The stake of 1-upper strata foundation pile 2-anchor pile 3-shallow-layer foundation pile 4-slip girder steel 5-deep layer gathers top 6-deep layer foundation pile
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: a kind of road and bridge described in the utility model damping device, include upper strata foundation pile 1, anchor pile 2, shallow-layer foundation pile 3, slip girder steel 4, the deep layer stake gathers top 5 and deep layer foundation pile 6 is formed.Said deep layer foundation pile 6 is to be vertically set on the underground foundation pile of deep layer, can form be set with boring.If taking an examination to consider to be arranged on, the design specifications height of road and bridge, the following bottom of deep layer foundation pile 6 stablize on the face of rock stratum.Per three deep layer foundation piles 6 are a group, and per four groups are a big group, can be used as a deep foundation that exposes bridge pier.Top on said per three deep layer foundation piles 6, be provided with the deep layer stake and gather top 5, middle two groups deep layer foundation pile 6 upper ends, the deep layer stake of being arranged to gang gathers top 5, on said deep layer stake gathers top 5, be provided with slip girder steel 4, above the slip girder steel 4, be provided with shallow-layer foundation pile 3 again, with anchor pile 2 deep layer stake placed in the middle gathered top 5, slip girder steel 4 and shallow-layer foundation pile 3 and link together.On said shallow-layer foundation pile 3, upper strata foundation pile 1 is set again, just the above foundation pile in ground.A kind of road and bridge described in the utility model damping device, overall structure is simple, and is easy for operation, between said deep layer foundation pile 6 and shallow-layer foundation pile 3, be provided with slip girder steel 4,, and improved the anti seismic efficiency of road and bridge with this as the device that receives earthquake shock power.
Claims (1)
- One kind road and bridge damping device, per three deep layer foundation piles (6) are a group, per four groups are a big group, can be used as a deep foundation that exposes bridge pier, its feature is in the last top at said per three deep layer foundation piles (6), be provided with the deep layer stake and gather top (5), middle two groups deep layer foundation pile (6) upper end, the deep layer stake of being arranged to gang gathers top (5), on said deep layer stake gathers top (5), be provided with slip girder steel (4), above the slip girder steel (4), be provided with shallow-layer foundation pile (3) again, deep layer stake placed in the middle gathered top (5) with anchor pile (2), slip girder steel (4) and shallow-layer foundation pile (3) link together; On said shallow-layer foundation pile (3), upper strata foundation pile (1) is set again.
