Description
Technical field
The utility model belongs to bridge foundation construction field, is applicable to ultra-large type Bored Pile Foundation construction in water.
Background technology
1) conventional piles construction technology in water:
Steel casing is exactly in carrying out the process of pile foundation construction, because soil property is unstable, so construction reinforced bar concrete guard wall exists larger difficulty to adopt the retaining wall of steel to protect hole stake, prevents that 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, can also isolate surface water, the effect such as starter, spud pile position, protection operation original ground.Steel casing is the important structure 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 place, on-the-spot stake position vibration-sunk.
2) limitation of traditional construction technology:
When tradition construction technology adopts the construction of steel casing, after pile foundation construction completes, casing steel are not recyclable, thereby 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 technology is only suitable for the less steel casing of drilled pile diameter, when stake footpath is over 2.4 meters, when casing wall thickness is greater than 30mm, casing rolls difficulty will be increased greatly, has increased great difficulty to processing, transportation and the lifting of steel casing, and the difficulty of construction of shaking in heavy process in construction also can increase greatly.Visible, traditional handicraft has certain limitation, and particularly, in the work progress of large diameter pile, limitation is larger.
Utility model content
The purpose of this utility model is: for super-large diameter drilled pile (diameter is greater than 2.4m) construction, propose a kind of antinode plate fore shaft steel casing device of constructing more convenient, cost is lower.
The utility model object realizes by following technical proposals:
A kind of antinode plate fore shaft steel casing device, comprise by several antinode plates annular steel casing that amalgamation forms that joins end to end, described antinode plate is equipped with locking mechanism from beginning to end, adjacent wave web is connected by this locking mechanism, described steel casing inwall removably connects and is fixed with at least two-layer up and down horizontal ring beam, 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 casing, each antinode plate can factory be directly realized processing also can on-the-spot processing in advance, and working (machining) efficiency is higher; Each antinode plate can become steel casing by on-the-spot direct-assembling, fast and easy and not limited by construction diameter; After large diameter pile construction, the steel of recyclable steel casing are reused, and reduce costs; The outer warpage of plane that utilizes antinode plate, increases steel casing out of plane stiffness, thereby under less wall thickness, meets structural stability requirement, and then reduce dead load, reduces lifting and drops into.Horizontal ring beam, in order to set wave web fore shaft steel casing, 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 that is two-stage boss shape, the outside turnup in main part two ends is bent into the described locking mechanism that hook forms, and the main part two-stage boss shape opening of each antinode plate of described steel casing is arranged alternately outward in steel casing or towards steel casing.
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, further improve the block-water performance of locking mechanism.
As further selection, described waterproofing agent is butter or epoxy mortar.
As selection, described horizontal ring beam is spliced to form from beginning to end by a plurality of Curved beams.
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 casing top.
As selection, described horizontal ring beam removably connects fixing by bolt and described steel casing.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form a plurality of schemes, be that the utility model can adopt and claimed scheme.
The beneficial effects of the utility model: this steel sheet pile shaped steel casing device, the shortcomings such as the construction of conventional steel casing is not recyclable, wall thickness large, outerplanar rigidity is little have been overcome, use this device, can save great deal of steel, reduce structure wall thickness, increase structure outerplanar rigidity, reduce super-large diameter drilled pile construction difficulty.
