Description
Technical field
The present invention relates to bridge pile foundation installing area, specially a kind of large bridge pile foundation construction side that pile bearing capacity is high
Method.
Background technique
The deep foundation being made of the pile framing of stake and connection stake top or the single-pile foundation being connect by column with pile foundation, abbreviation stake
Base, if pile body is all embedded in soil, cushion cap bottom surface is contacted with the soil body, then referred to as embedded footing on piles, low capped pile foundation；If pile body top is basseted
And cushion cap bottom is located at ground or more, then referred to as elevated footing on piles, building pile foundation is usually embedded footing on piles, low capped pile foundation plinth, and bridge foundation is bridge
The lowermost part that girder construction object is directly contacted with ground is the important component of bridge substructure, bears what basis was transmitted
A part of stratum in the portion of load is then known as ground, and after ground and basis are by various loads, itself will generate stress and deformation,
In order to guarantee the normal use and safety of bridge, ground and basis must have enough strength and stabilities, and deformation also should be
Within permissible range, compared with buildings in general basis, bridge foundation is embedding relatively deep, and the open cut of general provision bridge, is sunk at open caisson
The substrate on the basis such as case presses its importance and maintenance and reinforcement difficulty or ease, for land pile foundation, in addition to considering foundation frost heaving and requiring,
It is also contemplated that the destruction of biology and mankind's activity and other natural causes to surface soil, substrate should be not less than 1.0 meters in below ground,
For Urban Bridge, often basic overhead in lowest water level or below ground, in order to avoid influencing the appearance of the city, base top planar dimension should be compared with pier
The sectional dimension at platform bottom is big, with benefit construction.
Measurement and subsequently capital construction of the high large bridge pile base construction method of existing pile bearing capacity for bridge pile
If cannot correspond to completely, easily cause the big ground of pile foundation small in this way and the big problem of the small ground of pile foundation, once as occurring
Situation workpeople just does over again, and can significantly dally over one's work the time, brings trouble, increases the working time, no
Conducive to people's use.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of large bridge pile base construction method that pile bearing capacity is high,
Solve the high large bridge pile base construction method of existing pile bearing capacity for bridge pile measurement and subsequently capital construction set
The problem that cannot be corresponded to completely.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of Large bridge that pile bearing capacity is high
Beam pile base construction method, specifically includes the following steps:
S1, first by need to carry out using pile foundation be delivered to bearing capacity of pile foundation detection zone and detect, measure pile foundation
Bearing capacity whether meet construction requirement, pile foundation is placed on testing stand, is tested, to pile foundation apply pressure, measure stake
Whether the bearing capacity of base complies with standard, and the bearing capacity limit of detection of pier foundation simultaneously, facilitates people's subsequent use；
The pile foundation that S2, bearing capacity measurement terminate measures again, successively measures the length, height and width of pile foundation,
Can be more accurate when ground can be allowed to build, it is measured by tape measure, and the vertical of tape measure is adjusted by level meter
Property, it is ensured that the accuracy of measurement data；
S3, pile foundation will be delivered to the position constructed after all measuring, and bridge pile foundation figure is larger, in this way
It needs to be placed on pile foundation on bulk transport vehicle, then pile foundation is fixed by multiple fixing belt, can carry out in this way
Transport；
S4, while ground is transported, construction site obtains the length of pile foundation, carries out after the data of width and height
Ground is built, piling is carried out in the place that pile foundation is installed and pours a series of construction, then pile foundation is waited to transport to ground
Base；
After S5, pile foundation are delivered to installation place, first by Large-scale Hoisting equipment, pile foundation is hung into rise, then by bottom worker
It is drawn, pile foundation is sent to the top of ground, then hanging device slowly puts down pile foundation, and is bonded with ground perfection, to
Ground extracts the traction rope of hanging device out after being bonded with pile foundation, such pile foundation installs substantially；
S6, carry out casting cement in pile foundation and ground junction, and consolidation process will be carried out around ground, it is ensured that ground with
The connection degree of packing of pile foundation may insure the safety that the pile foundation later period uses in this way, then carry out to the surface of pile foundation and ground
The more coarse place of ground and pile foundation surface is carried out grinding process by cleaning, it is ensured that the aesthetics of ground and pile foundation, then by pile foundation
Grave mound is carried out with ground junction, and grave mound ensures that soil is consistent with road surface at the top of ground, then tamps soil, this
Sample pile foundation just installs.
Preferably, the time of measuring of the S1 pile foundation also must be up to standard, carries the time even if bearing capacity of pile foundation is qualified
Deficiency is also classified as underproof pile foundation, not can be carried out use.
Preferably, in the S2 measurement data must with to be delivered to the pile foundation that opens up ground completely the same, and pile foundation is transported
Pile foundation also must be corresponding with the ground opened up.
Preferably, the medium-and-large-sized transport vehicle of the S3 ensures to have good damping property and stability, because pile foundation figure is very big
And it is extremely heavy, once it can be very dangerous if stability and damping property performance difference.
Preferably, the ground needs built in the S4 are detected according to the geographic basis at construction, once at construction
Soil and its it is soft it is rotten if need by ground build it is deeper, detected i.e. if soil is more hard according to construction criteria
It can.
Preferably, it must be careful when being installed in the S5, and staff cannot stand in the bottom of pile foundation, once
Generation accident will be irretrievable, and pile foundation is extremely heavy, and installation needs and its careful.
Preferably, it does not need to be beautified comprehensively in the maintenance of the S6 middle and later periods, it is only necessary to general and its obvious and obstruction
What people used be discord, and place beautifies, and need to pour when casting cement it is primary after wait first time cement to parch completely
After continue to pour second
(3) beneficial effect
The present invention provides a kind of large bridge pile base construction methods that pile bearing capacity is high.Have compared with prior art with
It is lower the utility model has the advantages that
(1), the high large bridge pile base construction method of the pile bearing capacity must also be reached by the time of measuring of S1 pile foundation
Mark is classified as underproof pile foundation bearing capacity of pile foundation qualification carries time deficiency, not can be carried out use, measure number in S2
According to must with to be delivered to the pile foundation that opens up ground completely the same, and the pile foundation of pile foundation transport also must be corresponding with the ground opened up,
