Description

A kind of construction method and constructing structure for closing on both wired bridge pile foundations
Technical field
The present invention relates to Bridge Pile Foundation Construction method field more particularly to a kind of construction parties for closing on both wired bridge pile foundations Method and constructing structure.
Background technique
With the fast development of Chinese national economy, freeway net, railway reticular density are constantly promoted, traffic aisle resource Increasingly in short supply, the intersection between multiple transportation modes, which is passed through, gradually to be increased.Crossings on different level between a plurality of route mainly use across Bridge and under-traverse tunnel, when using in bridge structure across it is both wired when, the construction method of bridge pile foundation is just particularly important.Choosing Suitable construction method is selected, newly building bridge construction safety region and existing traffic route (highway, railway etc.) equipment are avoided And the collision problem of safe operation.
Existing manual digging pile construction method is mainly blasting, and there are many drawbacks for this method: due to explosion When there are lot of unstable factor, be easy that hole wall is caused to damage, easily cause pore-forming irregular, cause the super number formulary amount of concrete compared with Greatly;And blast working noise is larger, is affected to surrounding enviroment, safety is relatively poor.And Construction technology of bored pile is for example Using heavy mechanical equipment (rotary drilling rig, impact drill etc.) although degree of safety is higher in the construction process, speed of application is fast, Equipment is too big, and transfer process is difficult, is especially inconvenience in the pole operation of narrow complicated construction place;Construction noise is big, pollutant It is more, generate a large amount of dusts.During everyday practice, the method for cooperating manually digging hole to slag tap not only constructing operation is bored using water mill Conveniently, occupied ground is small, small to external environment influence, additionally it is possible to be solved with shorter duration, lower cost, preferable effect Under complex geological condition and the manual digging pile construction operation in limited operability face.
Summary of the invention
For deficiency existing for above-mentioned construction method, the purpose of the present invention is to provide one kind to close on both wired bridge pile foundations Construction method and constructing structure, do not need not impact both wired operation using mud.
For this purpose, the technical solution adopted in the present invention is as follows:
A kind of Bridge Pile Foundation Construction method for closing on existing line base, includes the following steps:
S1. positioning is measured to stake holes place, and in stake holes two sides construction fore shaft;
S2., equipment of slagging tap is installed, and clump weight is set in equipment of slagging tap;
S3. after the stake bit line of stake holes is set, the covering soil body is successively excavated from top to bottom, first digs the earthwork of middle section, then Periphery is extended to, excavating sectional dimension should be controlled by the outer diameter of steel pile casting;
S4. the every excavation of stake holes completes a section, and a section steel pile casting is arranged in time and follows up;
S5. it after pore digging to middle weathered rock formation, uses water mill instead and bores and continue borehole;
S6. after the completion of water mill bores borehole construction, the construction of subsequent cycle is modified and started to stake holes.
Further, in the step S1, fore shaft uses concrete structure, and answers 30cm above ground level;It is set at the top of fore shaft Steel plate cushion block is set, fixing steel plate is transmitted to the load on retaining wall when for bearing casing follow-up, prevents casing follow-up process from destroying Fore shaft.
Further, in the step S3, it should be carried out using pick, spade when excavating the upper layer covering soil body, meet hard soil layer, use Pricker is broken, excavates sectional dimension and controls by casing outer diameter, the height for excavating every section should be according to geological state, every section excavation height one As be 1.0m.
Further, in the step S4, when head section steel pile casting is transferred, on the top of steel pile casting, welding casing positions steel Plate, steel pile casting are fixed on fore shaft by fixing steel plate;It then proceedes to excavate, excavate after completing the second section, first risen using crane The second section steel pile casting is hung, then by itself and head section steel pile casting welding, and the casing fixing steel plate on first section steel pile casting top is removed, leads to It crosses crane and head section steel pile casting is slowly sunk down into stake holes bottom hole;Casing fixing steel plate is welded on the second section steel pile casting, and should Casing fixing steel plate is placed on fore shaft to prevent digging process steel pile casting from dropping, and then proceedes to excavate, and is so recycled, until steel Shield-tube embedment is completed.
Further, the step S5 includes S501. stake holes periphery coring: water mill bores aperture and carries out along stake holes surrounding, first Inner wall along stake holes arranges coring point, keeps coring circle tangent with fore shaft inner wall, is then successively drilled down to 3 ~ 5 ° of camber angle outer The core in week, periphery core take rear intermediate rock mass and just form an annular free face;
S502. stake core punches: after the completion of drilling and coring construction, with electric hand drill on rock mass jewel hole, then stake core rock is divided into 6 Equal portions or 8 equal portions are convenient for rock masses fracturing;
S503. stake core decomposes: insertion gad, impact gad successively divide rock mass in the hole that electric hand drill drills out, until this layer of stake Core rock mass is all broken;
S504. drill core is transported outward: water mill bores construction and carries out on one side, transports outward on one side to the drill core of taking-up, and drill core is transported outward from stake holes Side carry out, by hoist engine promoted suspension bucket to stake holes fore shaft, rotation hoist engine simultaneously the stone in suspension bucket is dumped into out Slag charge bucket is transported to specified Dumping Sites.
