Technical Field

The invention relates to a novel steel casing special for a lake gallery road.

Background

The lake trestle is a sightseeing corridor which is built on a lake, particularly a lake in a scenic spot, through a steel-concrete structure and is used for pedestrians to walk, and the construction requirement of the sightseeing corridor is lower than that of a bridge.

In scenic spot development, the mode of building of lake landing stage often adopts to find time the lake or building interim cofferdam, builds out an anhydrous environment in the lake, carries out the building of landing stage again, and this kind of mode of building often drops into great earlier stage, and in addition, in the great lake of waters area, the construction time overlength of this kind of mode of building earlier stage and unsatisfactory.

Based on the above situation, the construction mode of constructing the lake plank road by laying the steel pile casings is gradually adopted, but the traditional steel pile casings are low in structural strength and poor in waterproof performance of pipe walls, and cannot be directly used for constructing the lake plank road.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a novel steel casing special for a lake gallery channel.

A novel steel casing special for a lake gallery comprises an outer steel pipe, a bottom taper drill and a plurality of inner casing pipes which are connected end to end; outer steel pipe cup joint on the outer wall of inner casing, the afterbody of bottom toper brill and outer steel pipe links to each other, the bottom of inner casing is passed through the connecting pipe and is bored continuously with the bottom toper, and the bottom of inner casing all is equipped with a plurality of arcs protrudingly, the bellied afterbody of arc is equipped with the direction inclined plane, and the top of inner casing all is equipped with the arc recess corresponding with the arc is protruding, the bellied both ends of arc all are equipped with the counter bore, the counter bore in be equipped with locking spring and steel ball, the afterbody of steel ball links to each other with locking spring, the both ends of arc recess are equipped with the hemisphere breach that matches with.

To ensureThe inner protective pipe can not be extruded and deformed by pressureThe butt has a plurality of elasticity to prop the ring on the inner wall of inner sheath, elasticity prop the ring and include the semicircular steel ring that two symmetries set up, the tip of steel ring all is equipped with the connecting block, link to each other through the stereoplasm spring between the connecting block.

In order to prevent the sliding phenomenon between inner casing and the outer steel pipe, be equipped with the heavy groove of a plurality of arc on the outer wall of inner casing, be equipped with elastic gasket in the heavy groove of arc, elastic gasket's surface even has anti-skidding piece, anti-skidding piece include two transversal triangle-shaped's of personally submitting back-off spare, back-off spare from top to bottom thickness reduce gradually, the outer wall of back-off spare and the inner wall looks butt of outer steel pipe.

Preferably, the surface of the reverse fastener is a knurled surface.

Preferably, the bottom of the inner protecting pipe is provided with three arc-shaped bulges.

Preferably, the top of the bottom conical drill is connected with the tail part of the outer layer steel pipe through welding.

Preferably, the bottom of the bottom countersink is tapered.

Preferably, the material of outer steel pipe is Q235B.

Has the advantages that:

the inner protective pipes are connected end to end through the matching between the arc-shaped bulges and the arc-shaped grooves, and the steel balls are clamped in the hemispherical notches, so that the quick clamping between the adjacent inner protective pipes can be quickly completed; the inner protection pipe which is connected in a multi-section mode is located inside the outer steel pipe, the outer steel pipe can be effectively reinforced, and the phenomenon that the outer steel pipe is extruded and deformed in the sinking process is avoided.
