Abstract
The invention discloses a construction method of a trestle steel pipe pile foundation. The construction method is used for performing anchoring construction for the trestle steel pipe pile foundation on a slope bare rock surface and a shallow covered slope rock surface of the river, lake or ocean. The construction method comprises the following steps: A10) after utilizing an anchoring system to accurately position a floating pilot hole platform, respectively guiding each trestle steel pipe pile to fall onto a river bed rock surface but not perform a rock anchoring, through each reserved hole position on the floating pilot hole platform; A20) after impacting a hole to a designed depth on a foundational bed rock surface in the trestle steel pipe pile by using an impacting drill with the diameter less than the inner diameter of the trestle steel pipe pile, vibrating the trestle steel pipe pile so as to guide the trestle steel pipe pile to sink to the bottom of the hole, pouring reinforced concrete and firmly connecting the trestle steel pipe pile to the foundational rock; and A30) welding a trestle steel pipe pile connecting system, thereby finishing the construction for the trestle steel pipe pile foundation. According to the construction method, the operation of drilling the pile and steel pipe pile is adopted for construction, thereby efficiently resisting the influences of water flow, wind wave and air load and ensuring the stability and structural safety of the trestle.
Description
Technical field
The present invention relates to method for bridge construction, be specifically related to the job practices on trestle steel pipe pile basis, be used for carrying out trestle steel pipe pile basis anchoring construction at rivers, lake or the naked scar of deepwater inclination or shallow covering layer inclination scar.
Background technology
Along with the development of society, all kinds of bridge construction engineerings are more and more.Trestle is in the past generally all built on the thicker rivers and lake of covering layer, and under this geological conditions, the trestle foundation construction of leading to major project is general adopts traditional " halieutics " to carry out.But; There are a lot of rivers, lake and Marine Geology situation to be naked scar and the shallow covering layer inclination scar of tilting; As adopt conventional method to construct; Because the role and influence of current, stormy waves and wind load, the anchoring of mouth can't be guaranteed at the bottom of the stable and steel pipe pile on trestle basis, thereby influences the security performance of trestle and the construction speed of major project.
Because on rivers, lake and deepwater oblique scar tabula rasa rock or shallow covering layer, the foundation construction of trestle steel pipe pile can't adopt traditional inserting to beat the steel pipe pile job practices, therefore, presses for and seeks a kind of new job practices, addresses the above problem.
Summary of the invention
Technical problem to be solved by this invention is to solve the problem of how under tilt naked scar and shallow covering layer inclination scar geological conditions, to carry out trestle steel pipe pile basis anchoring construction.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopted provides the job practices on a kind of trestle steel pipe pile basis; Be used for carrying out the foundation construction of trestle steel pipe pile at rivers, lake or the naked scar of deepwater inclination or shallow covering layer inclination scar, this method may further comprise the steps:
A10, utilize anchorage system that floating pilot hole platform accurately behind the location, is fallen to the riverbed scar through each position, predetermined hole on the floating pilot hole platform with every trestle steel pipe pile respectively, but do not go into the rock anchoring;
A20, use drill hammer that diameter is slightly less than trestle steel pipe pile internal diameter in the trestle steel pipe pile to bedding scar impact holing to projected depth, at the bottom of trestle steel pipe pile vibration-sunk follow-up to hole, perfusion steel concrete makes trestle steel pipe pile and basement rock fixed;
A30, welding trestle steel pipe pile connect system and accomplish the steel pipe pile foundation construction.
In said method; In steps A 10; Said floating pilot hole platform is made up of barge and operation platform, is respectively equipped with the position, predetermined hole of a plurality of trestle steel pipe piles on the said operation platform, before the every trestle steel pipe pile that sinks; On said operation platform, leading truck is set, utilizes the verticality of leading truck control trestle steel pipe pile sinking process.
In said method, in the steps A 10, after the trestle steel pipe pile falls to the riverbed scar, remove corresponding said leading truck.
In said method, in steps A 20, after inspection trestle steel pipe pile verticality and steel pipe pile centre coordinate suitable for reading meet design requirement, pour into the anchor bar concrete again.
The present invention; According to the tilt construction characteristic of naked scar or shallow covering layer inclination scar of rivers, lake or ocean; Adopt the job practices of " drilled pile+steel pipe pile "; Can effectively resist the effect of current, stormy waves and wind load, guarantee the stable and structural safety of trestle, guarantee that oblique scar tabula rasa rock, the foundation construction of shallow covering layer trestle steel pipe pile meet the requirements.

The specific embodiment
The invention provides the job practices on a kind of trestle steel pipe pile basis; Adopt the job practices of " drilled pile+steel pipe pile "; Can effectively resist the effect of current, stormy waves and wind load; Guarantee the stable and structural safety of trestle, guarantee that oblique scar tabula rasa rock, the foundation construction of shallow covering layer trestle steel pipe pile meet the requirements.
Below in conjunction with the specific embodiment and Figure of description the present invention is at length explained.This specific embodiment is an example with the naked scar riverbed construction of tilting.
Job practices provided by the invention may further comprise the steps:
A10, like Fig. 3, shown in Figure 4, utilize 4 pairs of floating pilot holes of anchorage system platform accurately behind the location, through each position, predetermined hole on the floating pilot hole platform every trestle steel pipe pile is fallen to the riverbed scar respectively, but does not go into the rock anchoring.
Like Fig. 1, shown in Figure 2; Floating pilot hole platform is made up of barge 1 and operation platform 3, is respectively equipped with a plurality of positions, predetermined hole that are used to install the trestle steel pipe pile on the operation platform 3, and leading truck 2 is set on operation platform 3; Use crane gear 6 that trestle steel pipe pile 5 is sling; As guiding device, 5 deadweights of trestle steel pipe pile are installed trestle steel pipe pile 5 end mouth to scar as power and are promptly stopped, and do not carry out vibration-sunk with leading truck 2; Prevent that scar from tilting to cause trestle steel pipe pile 5 along scar slippage or inclination, causes off normal.After trestle steel pipe pile 5 falls to the riverbed scar, remove corresponding leading truck 2.
