Technical field
The present invention relates to a kind of technical field of steel lifted trunk, specially one kind exempting from bottom concrete steel lifted trunk bottom plate and steel shield
Cylinder attachment device and its construction method.
Background technology
In recent years, flourishing with China's expressway construction, it is super-huge across great river, great river, bay, straits etc.
Bridge continues to bring out, and the construction of a large amount of deep-water bridges is necessarily put forward higher requirements to the construction of bridge foundation.Territory the Liao Dynasty of China
Wealthy, the hydrology, geology, weather conditions are complicated and changeable, and the method and complexity of foundation construction are had nothing in common with each other on bridge water, base waterborne
Plinth is constructed because sightless unknown factor is more, parameter is big, the bridge foundation construction difficulty especially under Complex Hydrogeological Conditions
It is larger, have become the most critical technology in large bridge construction.
Steel lifted trunk is suitable for high-rise pile cap construction, and the dry operating environment of bearing platform construction is provided by side plate and bottom plate, is reached
This target is mainly by realizing following key technology：（1）The steel lifted trunk bottom plate and side plate knot that design stress is met the requirements
Structure；（2）Sealing problem between siding and between siding and bottom plate；（3）The connectivity problem between steel lifted trunk bottom plate and steel pile casting is solved,
So that steel lifted trunk bears vertical force（The vertical effect of water buoyancy and cushion cap concrete liquid-plastic state）When it is in a safe condition, and
Ne-leakage phenomenon between steel pile casting and steel lifted trunk bottom plate.
For the structure design of first problem, there is very ripe design method and economic design standard；It is right
In Second Problem, weld seam full qualification can realize good water-stagnating effect between plate by rubber fastening band；For third
Problem is generally realized using the modes such as welding shear connector on bottom concrete and steel pile casting.
It is excessive using general method back cover concrete usage amount for above-mentioned third problem, using exempting from back cover concrete method
The construction setting in some steel lifted trunks is influenced again.
Through retrieving the Chinese patent literature in relation to steel lifted trunk, it is as follows now to enumerate some：

9. a kind of construction method for exempting from bottom concrete steel lifted trunk bottom plate and steel pile casting attachment device, which is characterized in that the side
Method includes the following steps：
（1）Steel pile casting is transferred, carries out pile foundation construction, while steel lifted trunk bottom plate, steel lifted trunk side are carried out according to suspended steel box design drawing
The making of plate and support structure；
（2）Added according to construction drawing fabrication and installation sleeve bottom plate reinforcing rib, set tube end plate, sleeve cage plate, set tube end plate annular
Strength rib and set tube end plate outer ring ribbed stiffener；
（3）Tube end plate and sleeve body welding will be covered, and the inside and outside triangle between erecting and welding set tube end plate and sleeve body is put more energy into
Plate；
（4）Sleeve body and support structure are attached, and the stiffener between installation set cylinder and support structure；
（5）Bracket is welded on the steel pile casting apart from water surface 1.8m or so, as steel lifted trunk platform for lining, lifting steel lifted trunk bottom
Plate, sleeve backplanes support install hanging box suspension system on bracket；
（6）Installation steel lifted trunk side plate, transfers guidance system and hangs system inner support, in place by steel lifted trunk decentralization；
（7）Installation sleeve cage plate is simultaneously transferred on set tube end plate, will be covered the gap between tube end plate and steel pile casting and is blocked, and
The underwater concrete for pouring 5cm lower than sleeve top after health reaches intensity requirement, realizes the company between steel lifted trunk and steel pile casting
It connects；
（8）Anti-floating compression bar is installed, completes to draw water in cofferdam, removes concrete laitance, and screed of mating formation in sleeve so that sand
Pulp surface maintains an equal level with steel lifted trunk bottom plate；
（9）Steel lifted trunk cage plate is installed on steel lifted trunk bottom plate, by steel lifted trunk cage plate inner ring side and steel pile casting outer wall full weld, outer annular edge
With steel lifted trunk steel plate of baseplate full weld, two curved plate seams carry out full weld connection, complete the installation of all steel lifted trunk cage plates；
（10）Steel lifted trunk suspension system, anti-floating compression bar and interior guidance system are removed, the binding of cushion cap reinforcing bar and concreting are carried out
Bearing platform construction is completed in work.
