Description
Technical field
The present invention relates to technical field of civil engineering, are specifically related to the side to be set a roof beam in place in bridge construction with foundation construction
Method.
Background technique
In field of civil engineering, bridge is as main traffic facility, and quickly, safety and the construction technology not disturbed residents be by more
Carry out more favors.It is well known that the beam body construction of bridge is most to use precast beam, installed using erecting machine, realizes quick, peace
The purpose constructed entirely.But the construction of bridge foundation needs to build by building temporary construction road, occupying a large amount of construction sites
Material and facility passes through these temporary construction road transports to construction site, and need to take up an area stacking.Due to the position to construct a bridge
It is typically in traffic prosperity location, or crosses over the important main line of communication or important production and living facility, or is located at zanjon shoal and paddy
Domain and waters are built temporary construction road, trestle and setting construction site, are both needed at these position construction bridges bases
Do the work such as a large amount of basement process, relocation of services, building moving, it may be said that be time consuming and expensive, often build these
The working measure expense that temporary construction facility (construction road, trestle and construction site) generates accounts for the ratio of the project cost up to 50%
More than, the construction time of occupancy can exceed that the direct construction time of bridge.
Currently, the box beam and bridge pier of pontic, are realized prefabricated installation substantially, are set up using erecting machine, it is not only quickly but also safe,
Influence simultaneously to construction site is smaller, using installed bridge as transport routes, is not required in addition build temporary road.
But current erecting machine, during mobile set a roof beam in place, the front end of stretching need to be supported on the bridge foundation constructed, otherwise frame
Beam machine is in cantilever position, and the load capacity of receiving is small, and stability is poor.If developing a kind of bridge foundation and erecting beam construction one
Machine, then the bridge foundation that the front end of this equipment is not completed is as supporting station, since pile driving equipment self weight and process generate
Vibration, it is ensured that the stabilization of the integrated machine equipment is more difficult, that is to say, that the construction method of this all-in-one machine is uneasy
Complete.
For the stability and security problem of all-in-one machine, need to make temporary support to the front end of all-in-one machine, this is also engineering circles
Technical problem in the urgent need to address.
Summary of the invention
Technical problem to be solved by the present invention lies in overcome problems of the prior art, provide bridge foundation
With the front end temporary support body scheme of erecting beam construction all-in-one machine.
The front end temporary support body structure is by support column, basic case, mobile device, fixed device and interim foundation pile
Deng composition；
The support column flexible length, the upper end are connect with all-in-one machine, and lower end is connect with basic case；Support column is 2
Steel column more than root is fixed on the front end of all-in-one machine, can slip into water；Its stretch mode is that screw type rotary is flexible or hydraulic
Cylinder body pushes flexible.
The basic case is in circular or rectangular cancelled structure, hangs on all-in-one machine, can go up and down in vertical direction；
Basic case is made of steel, in the cabinet of multiple separations, multiple pawl nails is distributed on cabinet lower end surface, can be inserted into foundation soil
In layer；Cabinet is in seal shape, can increase self weight full of water when being put on ground, and water discharge in case is reduced self weight when above mentioning；When
Basic case slips into water, and the water energy emptied in case when above mentioning generates buoyancy；
The mobile device is a kind of pulling equipment, can basic case and fixed device is put into ground stratum or be mentioned
It pulls out up；
The fixation device is by support column and basic case locking and the device for locking basic case and interim foundation pile；
The interim foundation pile is to be drilled into basic stratum to form pile foundation when playing supporting role, and completes Zhi Chengzuo
It can extract and reuse after.Interim foundation pile is made of spiral drilling rod and drill bit, and basic ground can be drilled by rotating in the forward direction
Pile foundation is formed in layer, when reverse rotation, can be extracted from basic stratum.
When foundation bearing capacity is higher, interim foundation pile can not used.
The moving method of the bridge foundation and erecting beam construction all-in-one machine front end temporary support body, specific step is such as
Under:
(1) the large arm beam of all-in-one machine is forward extended out, stops movement when reaching scheduled bearing position；
(2) elongate support column reaches design position；
(3) mobile device is opened, basic case is transferred on ground, the pawl in basic bottom face is followed closely and is embedded into foundation soil
In；
(4) hydraulic jack on support column is opened, one side elongate support column on one side adds basic case
Pressure, detects its bearing capacity, when reaching 1.3 times of design supporting forces, stops upper pressurization, using fixation device by support column
It is locked with basic case.
(5) it when the bearing capacity of foundation soil body is lower, needs to increase interim foundation pile to improve supporting force, is grasped from basic case
Make in platform, auger stem is screwed into foundation soil, forms interim foundation pile.Foundation pile is not less than 2；When basic case by great waves or
When tidal effect, the horizontal resist forces of basic case can be improved using interim foundation pile.
(6) when all-in-one machine needs to be moved to next position, auger stem should be first reversely rotated if any interim foundation pile, it will
Interim foundation pile promotes out；When being full of water in basic case, the water of cabinet should be emptied；Unlock fixed device, by support column with
Basic case separation；Using mobile device certain altitude will be mentioned on basic case；Simultaneously will support column length shorten, in order to
The large arm beam of all-in-one machine is advanced forward into next position.
The utility model has the advantages that bridge foundation and erecting beam construction all-in-one machine front end temporary support body solve piling process all-in-one machine
Problem is supported, blank on the equipment of quick bridge construction has been filled up under complex foundation, waters and ocean condition, with prior art phase
Than improving the safety and stability set a roof beam in place with foundation construction all-in-one machine, eliminating bridge foundation construction needs and largely build
Temporary road and the waste of job platform bring, the great warp with environmentally protective social value and reduction bridge construction project cost
Ji benefit.
