Abstract
The invention discloses a construction method for precise closure of steel sheet piles. The method comprises the steps that (1) a shape formed through enclosing of the steel sheet piles and related dimensions are measured, steel sheet pile pit slots are excavated at measured positions, and prepared short steel sheet pile samples are placed at the measured positions; (2) a level gauge and a theodolite are prepared on the pit slots and the ground, and a level degree and perpendicularity are adjusted at the same time; (3) one short steel sheet pile sample is drawn out from the placement position when the first steel sheet pile is driven, lock catches of two adjacent steel sheet pile samples are aligned, and the first steel sheet pile can be pressed in, so that the position of the steel sheet pile can be found accurately, and the perpendicularity of the steel sheet pile can be ensured; and (4) in the same way, the steel sheet pile sample adjacent to the first steel sheet pile is drawn out when the second steel sheet pile is driven, a catching groove of the second steel sheet pile is aligned with the lock catch of the first steel sheet pile and the adjacent steel sheet pile lock catch, then the second sheet pile can be inserted completely, and the same method is applied to the subsequent steel sheet piles till the precise closure of the last steel sheet pile is completed.
Description
Technical field
The invention belongs to construction technology in geotechnical engineering field, the construction method that more particularly to a kind of steel sheet pile precisely closes.
Background technology
Steel sheet pile has that intensity is high, lightweight, stable performance, construction transport and easy to maintenance, speed of application fast, quality is easily controlled, short time limit, and scene is clean and tidy.In addition, steel sheet pile can be reused, reduce investment outlay, thus obtained extensive utilization in Geotechnical Engineering.But steel sheet pile is in work progress, also can run into some problems, such as be difficult precisely to close in enclosed type steel sheet pile construction process Steel Sheet Pile, need to carry out last closure by modes such as artificial welding；During press-in steel sheet pile, the more difficult rectification of perpendicularity of steel sheet pile, steel sheet pile head is susceptible to displacement.
In the prior art, the problem being difficult for steel sheet pile precisely to close, is that method squeezed into by screen, abnormity pile construction method carries out enclosed type steel sheet pile construction by the way of generally adopting.
Screen-type squeezes into method, is in a row to insert 10-20 root steel sheet pile in saddle, in screen shape, then injection in batches again.First the steel sheet pile at screen panel two ends is beaten to designed elevation or certain depth during injection, become positioning sheet pile, then divide in centre that l/3,1/2 sheet pile are highly stepped to be squeezed in order.The advantage that screen-type squeezes into method is: can reduce heeling error accumulation, prevent excessive inclination, and be easily achieved closing and close up, can guarantee that the construction quality of sheet pile wall.Its shortcoming is: the Self-standing height of pitching pile is larger, and during pitching pile, stability is bad, and working security is not high.
Special-shaped pile construction method, is to be difficult, for steel sheet pile, the problem that precisely closes, and with techniques such as cutting, polishing, welding, whole steel sheet pile is closed by the profile of the off-gauge steel sheet pile of field fabrication.Deformed steel flats pile construction method, though making flexibly, targetedly steel sheet pile can be processed, but the crudy of special-shaped sheet pile is relatively difficult to ensure card, and squeeze into and extract also more difficult, the special-shaped sheet pile closing up especially for closing, is usually processed before closing is closed up as needed, often affects construction speed.
The problem being difficult to for steel plate pile verticality correct, the solution generally adopting is the perpendicularity checking, correcting steel sheet pile in work progress with instrument at any time, and progressively correction steel wire rope pulling pile body Bian Labian beats for run-off the straight.This kind of correcting method is calibrated using instrument and the artificial perpendicularity to steel sheet pile and is detected.This kind of construction method process is complicated, easily produces deviation, needs to readjust, waste time and energy after having deviation.
Content of the invention
The purpose of the present invention is the problems referred to above existing for prior art it is proposed that a kind of construction method of the accurate closure of steel sheet pile.
A kind of construction method of the accurate closure of steel sheet pile, mainly comprises the steps that 1) measure the shape surrounding of steel sheet pile and relative dimensions and dig out steel sheet pile pit surveying measured position, ready short steel sheet pile sample is positioned over the measured position of survey；2) level indicator is prepared on pit and ground and adjust level with perpendicularity with theodolite simultaneously；3) when beating first steel sheet pile, a short steel sheet pile sample is extracted out from the position placed, the lock of be aligned two adjacent steel sheet pile samples, first steel sheet pile is pressed into, can either accurately find the position of steel sheet pile, and the perpendicularity ensureing steel sheet pile can be grasped.4) likewise, second steel sheet pile, extract out with the first adjacent steel sheet pile sample of steel sheet pile, second steel sheet pile catching groove is directed at first steel sheet pile lock and adjacent steel sheet pile lock, completely insert second sheet pile, steel sheet pile equally uses this kind of method afterwards, and to the last a steel sheet pile precisely closes.
The invention has the beneficial effects as follows: this engineering method solve the last steel sheet pile often occurring during steel sheet pile construction closing close up problem and when being pressed into steel sheet pile steel sheet pile the perpendicularity problem that is difficult to control, completely can quickly close each steel sheet pile, the steel sheet pile of this kind of construction method press-in has very strong water resistance and compressive resistance performance, can be widely applied to the construction field of steel sheet pile.
Brief description
Fig. 1 is the schematic side view after first steel sheet pile press-in.
In figure: 1, the ground enclosed construction that short steel sheet pile sample surrounds；2nd, pit；3rd, first steel sheet pile.
Specific embodiment
For content of the invention, feature and effect of the present invention can be further appreciated that, hereby enumerate following examples, and it be as follows to coordinate accompanying drawing to describe in detail:
1) measured the shape surrounding of steel sheet pile and relative dimensions have dug out steel sheet pile pit 2 in the measured position of survey, ready short steel sheet pile sample 1 has been positioned over the measured position of survey, surrounds a ground enclosed construction 1；
2) level indicator is prepared on pit 2 and ground and adjust level with perpendicularity with theodolite simultaneously；
3), when beating first steel sheet pile 3, a short steel sheet pile sample is extracted from the position placed.It is directed at the lock of two adjacent steel sheet pile samples, first steel sheet pile 3 is pressed into, can either accurately find the position of steel sheet pile, can guarantee that the perpendicularity of steel sheet pile again；
4) likewise, second steel sheet pile, extract out with the first adjacent steel sheet pile sample of steel sheet pile 3, second steel sheet pile catching groove is directed at first steel sheet pile lock and adjacent steel sheet pile lock, completely insert second sheet pile, steel sheet pile equally uses this kind of method afterwards, and to the last a steel sheet pile precisely closes.
