Detailed description of the invention
Inventive feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, in order to the understanding of technical staff of the same trade:
Such as Fig. 1-4, in figure, labelling 1-13 is respectively as follows: riser 1, shrouding 2, upper liner plate 3, sleeve pipe 4, bolt hole 5, side wing 6, semicircle anchor ear 7, lower liner plate 8, protection set 9, steel-pipe pile 10, fixture 11, pile-driving and-pulling machine 12, bolt 13.
Embodiment: as Figure 1-4; the present embodiment is specifically related to a kind of end-protecting device for steel-pipe pile construction and method of work thereof, and this end-protecting device includes the spacing block set being fixedly welded on outside steel-pipe pile 10 end and the protection set 9 in steel-pipe pile 10 end that is fixedly clamped.
Spacing block set is weldingly fixed on the outside of steel-pipe pile 10 end; primarily serve the vertical spacing to protection set 9 and intermal force; it can be specifically the Steel Casing 4 employed in the present embodiment; the form of other spacing block set can certainly be used, such as along the curved plate form of the steel-pipe pile 10 circumferentially spaced-apart laying of outer wall.
Protection set 9 is specifically made up of two semicircular anchor ear 7, has the side wing 6 of outwards extension in the both sides of semicircle anchor ear 7, constitutes bolt fastening by plugging bolt 13 in the bolt hole 5 on side wing 6 and tightening between two semicircular anchor ear 7.In addition; the inwall of two semicircular anchor ear 7 is welded with curved upper liner plate 3 and lower liner plate 8; the most at a certain distance thus enclose composition limited impression; this upper and lower spacing distance is identical with the height of sleeve pipe 4; i.e. limited impression is suitable with the size shape of spacing block set (sleeve pipe 4), and mating between spacing block set with limited impression can constitute the spacing of in the vertical direction to protection set 9.It should be noted that the generation type for limited impression is the most unique, it is also possible to directly offer cell body on the inwall of semicircle anchor ear 7 by machining mode.
Upper port at protection set 9 is welded with a horizontal direction shrouding 2, and is vertically welded with riser 1 on the axis of shrouding 2, and riser 1 clamps for the fixture 11 on pile-driving and-pulling machine 12 as held part, thus drives protection set 9 and to steel-pipe pile 10 power transmission.
As Figure 1-4, the method for work in steel-pipe pile work progress is applied to comprise the steps: the present embodiment medial end portions protection device
