Description
Technical field
The utility model relates to a kind of piling and the built bridge abutment structure of increase platform cap composite reinforcement that can improve the longitudinal crack generation that new and old pile foundation and platform cap supporting capacity and globality, minimizing the old and new pile foundation and platform cap junction are brought out due to difference carrying simultaneously.Belong to bridge engineering field, be applicable to the pile foundation reinforcing construction engineering in all kinds of bridge engineering, be specially adapted to the reinforcing engineering of reorganization and expansion bridge, bridge pier and the excessive bridge of abutment length travel.
Background technology
At extensive new bridge construction simultaneously, remake old bridge project also constantly advances enforcement, and the transformation of existing building is thus lifted to remarkable position, needs to take necessary reinforcement measure to meet new using function requirement in considerable part old building transformation process.Moreover part engineering (be included in building and newly build up engineering) causes workmanship to there is certain defect because of various reasons, can meet structural safety and instructions for use after need carrying out consolidation process, this type of stabilization works presents and increases phenomenon year by year.
Bridge is the throat guaranteeing that highway is unimpeded, and its supporting capacity and the traffic capacity link up key completely.Old bridge supporting capacity is not enough, aging, breakage is a worldwide range problem.In recent ten years, traffic volume of highway rapid growth on the one hand, the vehicles of large-scale heavy duty get more and more, and need high-level bridge; On the other hand original highway bridge is because of aging, damaged and former design standard is on the low side, is difficult to the development meeting highway transportation.Pile foundation is railway, apply one of maximum base form in bridges in highway engineering.After bridge puts into effect, under upper load effect, often there is structural damage phenomenon; For bridge Reconstruction Project, often need carry out Strengthening Design to structure, pile body, and take corresponding Reinforcement.
At present, measure pile foundation being carried out to reinforcing has two kinds usually, and one is increase stake number reinforcement clump of piles method, and two is that original position heavily builds method.When taking piling process, though single-pile vertical orientation load can be reduced, but piling generally can only be added in the periphery of a clump of piles, a clump of piles is easily caused to be arranged irregular, when a clump of piles is reduced to plane rigid frame model, by forming the rigid frame that span is large, post number is few in a direction, cause it stressed larger, and the control stake become in a clump of piles, this is stressed also unreasonable to a clump of piles.The original position heavily method of building again sets pile body in former stake position, and the method construction period is longer, and comparatively large to pile peripheral earth moving, is unfavorable for the performance of Pile side soil body supporting capacity.
In sum, although in engineering more existing can be used for punishing that built bridge abutment structure is aging, the method for the problem of Lack of support, various defect, mostly need to destroy former bridge construction, and need to take the temporary traffic measures of control such as envelope road, less for bridge Road width or that traffic saturation degree is higher section is difficult to be suitable for; Increase when built bridge stake number reinforcement clump of piles method and original position heavily the method for building be difficult to solve load bang path and integral bridge sex chromosome mosaicism.
Given this, in order to enrich the method that built bridge abutment structure is reinforced, the problems such as the bang path be connected on after the built bridge strengthening of better solution and the globality of bridge, need badly at present invention a kind of can meet simultaneously reduce the structure influence of built bridge, the integrated carrying ability improving bridge, the piling not affecting the multipurpose such as normal traffic of its bridge and the built bridge abutment structure of increase platform cap composite reinforcement.
Summary of the invention
The purpose of this utility model provides a kind of and punishes the piling of the various defects such as built bridge abutment structure is aging, Lack of support and problem and the built bridge abutment structure of increase platform cap composite reinforcement, avoids the temporary traffic measures of control such as envelope road; Increase when solving built bridge stake number reinforcement clump of piles method and original position heavily the method for building be difficult to solve load bang path and integral bridge sex chromosome mosaicism; And speed of application is fast, effective.
