Description
Technical field
The invention belongs to bridge foundation construction field, be applicable to ultra-large type Bored Pile Foundation construction in water.
Background technology
1) conventional piles construction technology in water:
Steel pile casting is exactly in the process of carrying out pile foundation construction, and because soil property is unstable, construction reinforced bar concrete guard wall exists larger difficulty so adopt the retaining wall of steel to protect hole stake, prevents collapse hole from avoiding affecting a kind of works of construction speed and safety.It has stable hole wall, the hole that prevents from collapsing, form mud pressure, surface water can also be isolated, starter, spud pile position, the effect such as protection operation original ground.Steel pile casting is the important feature thing in Bored Pile Foundation of Bridge.Conventional steel casing adopts certain thickness steel plate scene or factory to roll.After completing, handling is to on-the-spot stake position place vibration-sunk.
2) limitation of traditional construction technique:
When traditional construction technique adopts steel pile casting to construct, after pile foundation construction completes, casing steel are not recyclable, thus cause great waste; And during conventional construction, in order to meet the local stability sexual needs of casing wall body, by job specfication requirement, casing wall thickness should reach radius-thickness ratio 1/120, and therefore traditional construction technique is only suitable for the less steel pile casting of drilled pile diameter, when stake footpath is more than 2.4 meters, when casing wall thickness is greater than 30mm, casing rolls difficulty will be increased greatly, adds great difficulty to the processing of steel pile casting, transport and lifting, and constructing, the difficulty of construction of shaking in heavy process also can increase greatly.Visible, traditional handicraft has certain limitation, and particularly in the work progress of large diameter pile, limitation is larger.
Summary of the invention
The object of the invention is to: for super-large diameter drilled pile (diameter is greater than 2.4m) construction, propose a kind ofly to construct antinode plate fore shaft steel pile casting device and construction method thereof more convenient, cost is lower.
The object of the invention is realized by following technical proposals:
A kind of antinode plate fore shaft steel pile casting device, comprise and to be joined end to end the annular steel pile casting that split forms by several antinode plates, described antinode plate head and the tail are equipped with locking mechanism, adjacent wave web is connected by this locking mechanism, described steel pile casting inwall removably connects and is fixed with horizontal ring beam at least two-layer up and down, and the horizontal ring beam of the superiors is provided with hanger.
In such scheme, for super-large diameter drilled pile (diameter is greater than 2.4m) construction, adopt antinode plate fore shaft steel pile casting, each antinode plate can factory directly realize processing also can on-the-spot processing in advance, working (machining) efficiency is higher; Each antinode plate can become steel pile casting by on-the-spot direct-assembling, fast and easy and not limiting by construction diameter; After large diameter pile construction, the steel of recyclable steel pile casting are reused, and reduce costs; Utilize the outer warpage of the plane of antinode plate, increase steel pile casting out of plane stiffness, thus meet structural stability requirement under less wall thickness, and then reduce dead load, reduce lifting and drop into.Horizontal ring beam, in order to set wave web fore shaft steel pile casting, is convenient to lifting simultaneously.
As selection, described antinode plate becomes section closely trapezoidal by a monoblock steel plate bending, its section configuration is by the main part in two-stage boss shape, the outside turnup in main part two ends is bent into the described locking mechanism that hook is formed, and the main part two-stage boss shape opening of each antinode plate of described steel pile casting is arranged alternately in steel pile casting or outside steel pile casting.
In such scheme, special locking mechanism and combination, after making drilled pile construction, can directly pull up each antinode plate one by one, recycles.
As selection, the locking mechanism that described each antinode plate connects is perfused with waterproofing agent.
In such scheme, improve the block-water performance of locking mechanism further.
As further selection, described waterproofing agent is butter or epoxy mortar.
As selection, described horizontal ring beam is spliced to form by multiple Curved beam head and the tail.
In such scheme, horizontal ring beam mounting or dismounting fast and easy, efficiency of construction is higher.
As selection, described horizontal ring beam is two-layer, and near steel pile casting top.
As selection, described horizontal ring beam removably connects fixing by bolt and described steel pile casting.
The main scheme of aforementioned the present invention and each further selection scheme thereof can independent assortment to form multiple scheme, be the present invention and can adopt and claimed scheme.
The construction method of aforementioned waves web fore shaft steel pile casting device, comprises the following steps successively:
A, the antinode plate prepared in advance is assembled into steel pile casting at the construction field (site);
B, on steel pile casting, install horizontal ring beam additional;
After C, integral hoisting put in place, carry out entirety with vibrating hammer to steel pile casting and shake and sink to position, horizontal loops of dismantling girder system, carries out drilled pile construction;
D, pile driving construction hole to be drilled are complete, then pull up one by one each antinode plate, recycle.
Beneficial effect of the present invention: this steel sheet pile shaped steel casing device, overcome the shortcomings such as the construction of conventional steel casing is not recyclable, wall thickness large, outerplanar rigidity is little, use the method, great deal of steel can be saved, reduce structure wall thickness, increase structure outerplanar rigidity, reduce super-large diameter drilled pile construction difficulty.
