Abstract
The utility model provides a steel pipe pile lock mouth structure, which is firm in mouth locking, good in water plugging effect and convenient to construct. The steel pipe pile lock mouth structure comprises a steel pipe, a lock mouth pipe and a lock mouth, wherein the lock mouth pipe and the lock mouth are arranged on the outer wall of the steel pipe, parallel to the steel pipe and have the same length as the steel pipe; a lock mouth groove is formed in the lock mouth pipe; the lock mouth pipe and the lock mouth form the angle of 180 degrees by using the axial line of the steel pipe as a center; the lock mouth groove is positioned on the extending line of the connecting line of the center of the lock mouth pipe and the center of the steel pipe; the lock mouth is composed of a stop plate and a pair of barrier plates; the barrier plates are symmetrically arranged between the stop plate and the steep pipe and are trumpet-shaped; the width of the outer side of the joint of each barrier plate and the steel pipe is less than that of the lock mouth groove; the width of the outer side of the joint of each barrier plate and the stop plate is larger than that of the lock mouth groove. The steel pipe pile lock mouth structure is convenient to construct, good in water plugging effect and firm in mouth locking.
Description
Technical field
The utility model relates to the steel pipe pile using in civil engineering cofferdam construction, relates in particular to a kind of locking notch structure of steel pipe pile.
Background technology
Along with bridge construction is to the development of large span direction, the construction method in large-scale underwater support table cofferdam is comparatively various, conventional is mainly precast reinforced concrete pile, prestressed reinforced concrete stake, bored pile, manually digging hole filling pile and steel pipe pile etc. at present, and often there is the phenomenon that connection is insecure or water plugging effect is poor in the syndeton of steel pipe pile of the prior art, be subject to the active force of external water pressure or inner transverse support bar, there is easily loosening risk in steel pipe pile, affects construction safety.
Utility model content
The utility model, for above problem, provides a kind of fore shaft firm, and water plugging effect is good, the steel pipe pile locking notch structure of constructability.
The technical scheme of utility model is: comprise steel pipe, locking notch pipe and fore shaft, described locking notch pipe and described fore shaft are all located on described outer wall of steel pipe and are parallel with described steel pipe, isometric, described locking notch pipe is provided with fore shaft groove, and described locking notch pipe and described fore shaft are 180 ° centered by the axis of described steel pipe;
Described fore shaft groove is positioned on the extended line of connecting line at the center of described locking notch pipe and the center of described steel pipe;
Described fore shaft is made up of check plate and a pair of barrier plate, described a pair of barrier plate is symmetrically set between described check plate and described steel pipe and is horn-like, the outside width of described a pair of barrier plate and described steel pipe junction is less than the width of described fore shaft groove, and the outside width of described a pair of barrier plate and described check plate junction is greater than the width of described fore shaft groove.
Described stiffener is all laid between described steel pipe and described locking notch pipe.
Described fore shaft forms a cavity after inserting described locking notch pipe, in described cavity, is provided with waterproof bag, in described waterproof bag, injects inserts.
Described locking notch pipe and described fore shaft are 90 ° centered by the axis of described steel pipe.
The utility model is located at fore shaft and locking notch pipe on outer wall of steel pipe, and fore shaft is inserted in locking notch pipe by the fore shaft groove on locking notch pipe, thereby two steel pipes are coupled together, constructability.After fore shaft is connected with locking notch pipe, a cavity of inner formation, is provided with waterproof bag in cavity, again inserts is injected in waterproof bag, can strengthen connection power and the water plugging effect of two steel pipes, directly not contact steel pipe because the existence of waterproof bag makes packing material, can ensure smooth pile pulling of later stage simultaneously.In the time injecting inserts, fore shaft is subject to the extruding force of inserts, outwards moves, and because the barrier plate on fore shaft is horn-like, the large opening of loudspeaker is towards check plate, and fore shaft and locking notch pipe block tighter and tighter, make to clamp effect better, and fore shaft is firm.

Detailed description of the invention
The utility model the first embodiment as Figure 1-5, comprise steel pipe 1, locking notch pipe 2, fore shaft 3 and some stiffeners 4, described locking notch pipe 2 is all located on described steel pipe 1 outer wall with described fore shaft 3, and parallel with described steel pipe 1, isometric, described locking notch pipe 2 is 180 ° with described fore shaft 3 centered by the axis of described steel pipe 1, the diameter of described locking notch pipe 2 is less than the diameter of described steel pipe 1, described locking notch pipe 2 is provided with the fore shaft groove 21 for inserting described fore shaft 3, described fore shaft groove 21 is positioned on the extended line of connecting line at the center of described locking notch pipe 2 and the center of described steel pipe 1,
Described stiffener 4 is all laid between described steel pipe 1 and described locking notch pipe 2, in order to increase the bond strength between described locking notch pipe 2 and described steel pipe 1.
Described fore shaft 3 is made up of check plate 31 and a pair of barrier plate 32, described a pair of barrier plate 32 is symmetrically set between described check plate 31 and described steel pipe 1, and be horn-like, the outside width of described a pair of barrier plate 32 and described steel pipe 1 junction is less than the width of described fore shaft groove 21, the outside width of described a pair of barrier plate 32 and described check plate 31 junctions is greater than the width of described fore shaft groove 21, make after described fore shaft 3 inserts described locking notch pipe 2, while being subject to the External Force Acting of cofferdam inner support pipe, described fore shaft 3 can tightly snap in described fore shaft groove 21, can effectively intercept outside water simultaneously.
Described fore shaft 3 inserts cavity of the rear formation of described locking notch pipe 2, in described cavity, be provided with waterproof bag 5, at the interior injection inserts 6 of described waterproof bag 5, described inserts 6 can be the low strength concrete mortar of certain denseness, can further intercept outside water, adopt described waterproof bag 5 can prevent that described inserts 6 from being broken up under water before solidifying, also between described inserts 6 and described locking notch pipe 2 inwalls, form separation layer simultaneously, facilitate later stage pile pulling, improve the cyclic utilization rate of described steel pipe 1.
