Abstract
The utility model relates to a pile-column integrative columnar pier structure without a supporting table. The basis of the utility model adopts a pile with a large diameter, the upper part of the basis is directly connected with a columnar pier with a large diameter, and the columnar pier is embedded in a main beam. The water surface position or the position which is separated from the pier at a certain height is provided with a frame style contact supporting plate or a contact plate in order to reinforce the connection of the column top and the main beam. The pier top is provided with a lateral contact plate which contacts the same row of pier columns in the position of the column top. Because the pier with the structure is not provided with the supporting table, the utility model has the advantages of low construction difficulty, low manufacturing cost, short construction time, high structural strength and beautiful appearance.
Description
Technical field
The utility model relates to a kind of bridge pier, the no cushion cap pile one columnar pier structure that particularly a kind of continuous rigid frame bridge adopts.
Background technology
At present in concrete continuous rigid frame bridge beam design, because the hydrology, geology, duration and equipment requirement must be adopted deep water foundation, common design scheme is that clump of piles top is provided with the scheme that cushion cap and wall formula thin-walled pier shaft join.But this scheme causes to adopt needs the subaqueous work cushion cap when hanging down cushion cap, and difficulty of construction is big, and the cost height is long in time limit; Adopt the cushion cap bottom surface to be higher than can pile foundation to occur with SEA LEVEL VARIATION when waterborne and expose, it is attractive in appearance to influence integral bridge.
Summary of the invention
The purpose of this utility model is to propose a kind of employing pillar pier shaft, the cancellation cushion cap, and one one post is to the continuous rigid frame bridge bridge pier structure that pushes up.
The technical solution of the utility model is: large diameter pile is adopted on the basis, directly be connected with the major diameter column pier on it, column pier gos deep in the girder, when the pier height is big, frame type contact support or contact plate are set at water surface site or along pier shaft certain altitude position, are convenient No. 0 piece cast-in-place construction, and strengthen being connected of capital and girder, at Dun Ding the lateral ties plate is set, same row's pier stud is connected in the capital position.
The utility model not only can guarantee substructure rigidity and the intensity that rigid frame bridge is required, and can avoid large volume bearing platform construction in the water, helps reducing difficulty of construction, reduces construction costs, shortens the construction period, guarantees that bridge is attractive in appearance.
Description of drawings
Fig. 1 is the schematic diagram that main bridge bridge type is arranged;
Fig. 2 is the bridge pier generalized section.
Fig. 3 is the A-A cut-away view of Fig. 2.Among the figure
1 bridge floor, 2 main piers
3 transition pier, 4 straining beams
5 casees beam 6 diagonal braces
The specific embodiment
As shown in Figure 1, main bridge bridge type can adopt three to stride the prestressed concrete continuous rigid frame, and bridge opening is arranged and be can be 56+104+56m, main bridge length overall 216m; Two main piers 2 all adopt 4 diameter 2m drilled pile bases, on connect 4 diameter 2m pier studs, be one one post to roof construction, twice frame type straining beam 4 is set more than ordinary water level, cancel conventional underwater support table, can save a large amount of cushion cap concrete.Main access bridge transition pier 3 can adopt 2 diameter 2m drilled pile bases, on connect 2 diameter 2m pier studs, also be that one one post is to roof construction.The transition pier bent cap adopts prestressed reinforced concrete construction.
Because main pier 2 and transition pier 3 all are arranged in deep water, construction period, the height of water reached 15～20m, and the while has the navigation requirement again, how fully to use the advantage that the riverbed covering layer is thin, basement rock intensity is high, reducing basic scale in the water, is the key of this bridge substructure design.Consider that from nature, execution conditions this bridge adopts the bundle pillar basis comparatively favourable, but cushion cap should not be set.Because of the height of water is big, from consideration attractive in appearance, the cushion cap bottom surface is located at the following scheme of water level and brings many difficulties to construction, is difficult to guarantee that engineering completes on schedule; Add the skirtboard scheme below the ordinary water level during the cushion cap bottom surface is located at, need 4～5m because of skirtboard is high, anti-ship hits ability, and construction also acquires a certain degree of difficulty.Comparatively ideal scheme is to adopt no cushion cap multi-column pier foundation scheme.Than choosing, main pier 2 adopts 4 diameter 2m drilled pile bases through multi-scheme, on connect 4 diameter 2m pier studs, do not establish cushion cap, be that one one post is to roof construction.Referring to Fig. 2, visually form integral body for making four pier studs, and reduce the pier shaft drift, increase the anti-ship collision ability of pier shaft, twice frame type straining beam 4 is set more than ordinary water level, with four pier studs in length and breadth to being unified into framework and being provided with diagonal brace 6 (see figure 3)s.The pier stud of can constructing earlier during construction, at the water level straining beam of constructing again under than the situation at the end, main pier foundation construction is not controlled by water level.
After adopting columnar pier,, can take following measure for guaranteeing the reliable and convenient construction of structure stress:
1. with pier stud center line and No. 0 piece web central lines, make vertical load not produce off-centre to pier stud, vertical force is directly passed to four pier studs by web;
2. pier stud is made progress extends to case back plate smooth-goingly, strengthens the effect that is connected of pier stud and case beam 5, guarantees the smooth-going transition in top and the bottom, avoids structural mutation to cause that stress concentrates, from visually also reaching safe, attractive in appearance effect;
3. corresponding case Liang Henggebanchu establishes the horizontal tie-plate of high 3m, wide 0.5m together under No. 0 piece in pier top, horizontal tie-plate direction across bridge links to each other with two pier studs, horizontal tie-plate can strengthen the globality of case beam and two pier studs in No. 0 piece work progress, be convenient to the setting of No. 0 piece construction bracket supporting member again;
4. when full-bridge vertically totally calculates the twice straining beam is modeled to two horizontal bars, considers its influence structure collectivity rigidity and local internal force.
The utility model is by adopting the new structure design of pile foundation and pier shaft, pier shaft and girder, and the bearing platform construction that cancellation is commonly used can realize reducing construction costs, reduces difficulty of construction, guarantees the purpose of bridge construction overall appearance.
