Specific embodiment
Technical solution of the present invention is described in further detail in the following with reference to the drawings and specific embodiments, it is described specific
Embodiment is only explained the present invention, is not intended to limit the invention.
The utility model proposes it is a kind of for pile foundation steel pile casting construction positioning guiding rack, as depicted in figs. 1 and 2, should
Positioning guiding rack includes a quadrangular frame, and the quadrangular frame includes a door frame 1 and an open frame, described
Open frame is that successively in addition fixation is on one side the frame on doorway on three sides, and the open frame is by three side stands 2
It constitutes, three side stands weld together, and the appended drawing reference 30 in Fig. 2 shows weld seam, and three side stands 2 are by adjacent three
Column 3 and the top beam 31 being arranged between two successively adjacent columns 3, bottom beam 32 and diagonal brace 33 are constituted, and the door frame 1 includes
The vertical beam 11 and upper beam 12 and lower beam 13 of two sides, the vertical beam 11 of 1 two sides of door frame respectively with the doorway of open frame
Hinged 20；Quadrangular frame top, the first locating rod 4 is welded between every two adjacent side stand 2, in order to even
The stability connect, two the first locating rods 4 and is respectively connected with support rod between two columns 3 being connected.The door frame 1 with
The second locating rod 5 is welded between the side stand 2 of two sides；It is one by three side stands in the quadrangular frame roof
The octagon connecting rod that the upper beam 12 of the second locating rod 5 of the first locating rod 4 two of top beam 31, two and door frame surrounds, eight side
The inscribed diameter of a circle of shape connecting rod is 2cm bigger than the outer diameter for the pile foundation steel pile casting 40 transferred in advance；In two the first locating rods 4 and described
Be equipped with guide roller 6 on the upper beam 12 of door frame 1, the inscribe diameter of a circles of three guide rollers 6 than with the pile foundation transferred in advance
The big 1cm of the outer diameter of steel pile casting 40.Multiple guide pads 7 are equipped at the top of the quadrangular frame, the medial surface of guide pad 7 is oblique
The medial surface in face, multiple guide pads 7 forms a horn mouth.
The positioning guiding rack is welded on drilling platform 8 with channel steel using when the positioning guiding rack, and in positioning and guiding
Strength plate 9 is welded on frame by positioning guiding rack in 8 upper limit of drilling platform.
The embodiment of sinking steel protecting canister is carried out using the utility model positioning guiding rack:
As depicted in figs. 1 and 2, total a height of 4m of positioning guiding rack is directly stood on above drilling platform, center and pile foundation
Center is overlapped.In view of steel pile casting handling enters the convenience in hole, the side of positioning guiding rack according to activity can evolution formula design, remaining
Three sides use stationary frame structure.Positioning guiding rack uses 4 symmetrical cloth of triangle bracket after being adjusted in place between drilling platform
Single-sided welding limit, floating-crane lifting steel pile casting are set, and is entered slowly.Positioning guiding rack is first by artificial coarse positioning, plan-position
Positioning accuracy deviation must not exceed 3cm, and after movable door frame is shut, the gap between steel pile casting and guide roller 6 is controlled by 1cm
System, the second locating rod of then burn-oning.
As shown in figure 3, the step of sinking steel protecting canister, is as follows:
(1) positioning guiding rack is in place: the plan-position of survey crew's setting-out positioning guiding rack 10, lifts positioning and guiding
Frame 10 is in place, adjusts verticality and the plan-position of positioning guiding rack 10.It by channel steel and is bored in the lower part of positioning guiding rack 10
Hole platform 8 welds, while using strength plate 9 by positioning guiding rack 10 in 8 upper limit of drilling platform.
(2) steel pile casting merogenesis lifts: steel pile casting uses 150t floating-crane lifting and installation, and longer steel pile casting is divided to two sections to rise
It hangs.
(3) steel pile casting lifts by crane, is in place, being fixed temporarily: slinging coxopodite steel pile casting using 150t crane barge, and is slowly sent into positioning
In leading truck 10, before steel pile casting will enter water, stop decentralization, and adjust steel pile casting to normotopia, by being mounted on positioning and guiding
Two the first locating rods 4 at angle are positioned in frame 10.
Designated barge is arranged at the about 100m of drilling platform upstream, on wirerope cable clamp under water steel pile casting, position exists
At the lower above 3m in section casing bottom, to prevent steel cable from sliding to the bottom, wirerope can be hung with 2 ropes made of hemp and be tied up on drilling platform
To control the elevation of wirerope；The wirerope other end refutes strand tank with positioning and connects, and passes through and twists the adjustable steel pile casting verticality of tank.In the water surface
Above, steel pile casting downstream side direction setting limit channel steel, the channel steel scene temporary weld, channel steel rear portion, which is set, shores and drilling platform
Structure is connected.Water is put under steel pile casting is slow to be drilled and consolidated with platform when top opening absolute altitude is higher than positioning guiding rack top 50cm
It is fixed.Fixed form can be used and weld bracket in steel pile casting (platform section below), is fastened by wirerope and buckles bracket and vertically fix.
Steel pile casting is saved in lifting, is connected with lower section steel pile casting.4 guide pads 7 are symmetrical arranged at the top of lower section steel pile casting, to
After upper section steel pile casting substantially enters in guide pad 7 in place, the slight off the hook of crane barge makes lower section casing bear to save casing in a part
Weight, under the effect of gravity and the guiding role of leading truck, upper section steel pile casting will with lower section steel pile casting is straight connects, at this time in
Seam crossing welds four horse legs, fixes its interface, and abutment joint is welded, and 45 ° broken should be arranged by section steel pile casting at seam
Mouthful.
The place connecting with positioning guiding rack is cut open after welding, and cancels steel pile casting vertical spacing, sinking steel pile casting,
When steel pile casting bottom end is buried, adjusts the verticality and the setting of port plane of steel pile casting again by tightening wirerope, meet the requirements
After start sinking steel pile casting.
(4) vibration hammer installation and vibration-sunk: when crawler crane places vibration hammer, after hydraulic tongs are aligned, casing is clamped, is delayed
Slow pine hook, measurement verticality carry out a vibration, measurement observation casing verticality and plan-position, vibration are applied after meeting the requirements and is extremely oriented to
Frame top opening；Remove upper layer leading truck, then Shi Zhenzhi designed elevation.After single casing sinking, immediately by its with sunk casing
It is linked to be entirety, prevents single casing from deviation occurs in flow action.
Although above in conjunction with attached drawing, invention has been described, and the invention is not limited to above-mentioned specific implementations
Mode, the above mentioned embodiment is only schematical, rather than restrictive, and those skilled in the art are at this
Under the enlightenment of invention, without deviating from the spirit of the invention, many variations can also be made, these belong to of the invention
Within protection.
