Abstract
The invention belongs to steel trestle construction method technical fields, propose a kind of construction method for deep water shallow overburden steel trestle.It is proposed a kind of construction method for deep water shallow overburden steel trestle, for riverbed bottom be rocky bed part steel-pipe pile, need to be squeezed into rocky bed to beat it is motionless until；Then steel-pipe pile is fixed on leading truck with channel steel, it is ensured that steel-pipe pile stability；It is the surrounding throwing sand pocket of all steel-pipe piles of rocky bed in bottom, forms sand pocket cofferdam；Pouring underwater concrete ensures that bottom is the steel-pipe pile of rocky bed and has enough building-in depths, meets resistance to capsizing requirement as artificial concrete coating in sand pocket cofferdam；While the present invention ensures steel trestle overall stability, project cost is reduced；The characteristics of this method is adaptable, convenient for construction, saving duration simultaneously.
Description
Technical field
The invention belongs to steel trestle construction method technical field, especially a kind of applying for deep water shallow overburden steel trestle
Work method.
Background technology
In-water foundation construction generally uses steel trestle as temporary traffic facility, is used for transport of materials, personnel, mechanical equipment
Temporary traffic waterborne etc.；Since holding force component is steel-pipe pile, therefore the stability of steel-pipe pile generates weight to the safe handling of steel trestle
It is big to influence.Mud, sand pebble layer can be encountered when usual steel trestle construction, provides execution conditions for rapping steel-pipe pile, but flowing
It is fast big, be under water solid rock, shallow overburden or intectate, the depth of water relatively depth or flood level are higher it is equal in the case of, steel-pipe pile is slotting
It is particularly difficult to play construction, it is difficult to the enough depth of underwater stratum be squeezed into, it is difficult to ensure that steel-pipe pile stability.
Existing patent of invention《The method that deep water steel trestle and platform are set up on the exposed bedrock of shallow sea》（The patent No.：
201210164272.6）, comprise the following steps：（1）Model is established, determines parameter；（2）Inserting piling trestle steel pipe pile；（3）Inserting piling side
It is supported to chamfer triangle taper pile；（4）Integral frame structure is molded；（5）Perform the knots such as trestle Bailey beam, floorings
Structure forms trestle.Patent to the effect that adds row's chamfer triangle taper pile in steel trestle steel-pipe pile both sides, by taper pile with
Trestle steel pipe pile is rigidly connected, to ensure steel-pipe pile stability；But in its work progress, the construction duration is long, quantities
Greatly, the amount of labour of construction personnel is big.
Invention content
The purpose of the present invention is according to the existing deficiency of above-mentioned engineering technology, propose a kind of for deep water shallow overburden steel stack
The construction method of bridge is suitable for the construction method of deep water shallow overburden steel trestle steel-pipe pile, especially suitable for being hard rock under water
Stone, shallow overburden or intectate, the steel trestle steel pipe pile driving construction in the case of the depth of water relatively depth or flood level are higher etc..
The present invention is to complete above-mentioned purpose to adopt the following technical scheme that：
A kind of construction method for deep water shallow overburden steel trestle, the construction method are as follows：
1）Model is established, steel trestle modelling is carried out, determines steel trestle steel-pipe pile model and meet under antidumping requirement condition
Artificial concrete coating parameters；
2）Steel-pipe pile is transferred into riverbed bottom in designated position using crane lifting vibration hammer；The steel-pipe pile is along steel trestle
Length direction setting two row, be often classified as it is multigroup, every group be two；For the steel-pipe pile that riverbed bottom is rocky bed part, need
Squeezed into rocky bed to beat it is motionless until；Then steel-pipe pile is fixed on leading truck with channel steel, it is ensured that steel-pipe pile is stablized
Property；
3）It is the surrounding throwing sand pocket of all steel-pipe piles of rocky bed in bottom, forms sand pocket cofferdam；
4）According to step 1）Calculate parameters obtained, in sand pocket cofferdam pouring underwater concrete as artificial concrete coating,
Ensure that bottom is the steel-pipe pile of rocky bed and there are enough building-in depths, meets resistance to capsizing requirement；
5）It is connected as with channel steel welding bridging, stull between every group of two steel-pipe piles, between the two corresponding steel-pipe piles of row
One, is allowed to constitute a frame structure, enhances the stability of steel-pipe pile；
（6）According to each steel pipe stake top of design altitude leveling after surveying and locating, 2/3 long gravel or coagulation are poured into steel-pipe pile
Soil enhances resistance to capsizing to reduce the center of gravity of steel-pipe pile；
7）Each steel pipe stake top after leveling is fixed with more Bailey beams being arranged along steel trestle length direction；The more shellfish thunders
Steel trestle floorings are fixed on the top of beam, and connect firmly steel trestle railing at the both ends of steel trestle floorings.
It is proposed by the present invention a kind of for deep water shallow overburden steel trestle construction method, by being rocky bed in bottom
Sand pocket cofferdam is cast around steel-pipe pile, and concrete perfusion establishes artificial concrete coating in sand pocket cofferdam, ensureing steel
While trestle overall stability, project cost is reduced；Simultaneously this method it is adaptable, convenient for constructing, save the spy of duration
Point.
