Abstract

An anchor is a main anchoring tool used for permanent mooring for an aquaculture net cage, a floating platform, a floating barrel, a buoy, a lightship, a floating dock, a pontoon and the like. Enabling an anchor to be embedded into the ground is the simplest and most effective method for improving anchoring force of the anchor. A driven type columnar ground anchor is in a mother-son pile mode, namely, a pile body is combined by an outer pipe, namely the mother pile and a central grouting pipe, namely the son pile. A pile tip is in a conical shape, and a guide pipe and a sealing plate which are driven in cooperation with a steam hammer are arranged at the upper end of the pile. A diving steam hammer of a long sleeve feeds an anchor body into a stratum with the assigned depth through the long sleeve to achieve grounding. The son pile is connected with a hose through a water pipe connector to a water surface grouting pump, the pile can conduct high-pressure grouting during beating, and the anti-pulling force is improved. The driven type columnar ground anchor is simple, practical and efficient and undoubtedly has great important value for permanent mooring for the aquaculture net cage, floating platforms comprising a small-size tension leg platform and an SPAR platform, the floating barrel, the buoy, the lightship, the floating dock, the pontoon and the like.

Summary of the invention

For anchor is reached, install simply, cost is low, good reliability, the object that has high uplift resistance, the technical scheme adopting is to have combined scientifically and rationally relevant several the patents of present inventor in inquiring into novel anchor in list of references [1] [2] [3],, technical characterictic is:

1. anchor body adopts " primary and secondary stake " pattern, be that pile body is combined by the i.e. son stake of outer tube Ji Muzhuanhe center Grouting Pipe, pile top is taper, stake upper end arranges guide pipe and the shrouding that coordinates steam hammer to squeeze into, son stake by water pipe head connecting hose to water surface grouting pump, stake is carrying out high pressure injection cement for construction in sea slurries with hitting, slurry infiltration forms the compound pile that is several times as much as caliber together with stake, particularly tamp space between stake and soil earth, thereby greatly improved uplift resistance, particularly at grey hermatolith layer and ferruginous sandstone layer, pile pipe is consolidated with it by mortar, like pile tube, be anchored on this firm hard formation, its ultimate pullout capacity almost approaches the stretching Strong degree of pipe shaft.

2. adopt the diving steam hammer of long sleeve, by sleeve, anchor body is sent into designated depth stratum and realize the ground of diving, owing to being that steam hammer is squeezed into stake with playing formula operation, owing to needn't employing pile driving barge, so piling cost is low.

3. the setting of anchor body adds Strong type hanger, hanger connects high drag rope cable, hawser is connected to mast-up, in work progress, it bears the lifting of anchor body and diving steam hammer, after finishing, piling can connect mooring body hawser, this mode has also solved anchor body etching problem, because depth of soils galvano-cautery can ignore, and rope cable is not afraid of corrosion.

4. anchor body and pile top, except doing with steel, can also select steel concrete to make, and now should notice that steel concrete should be used cement for construction in sea, have rational grating, and add short fiber and additive etc. and make its Strong degree high compactness good.

Due to its economic and practical, undoubtedly, aquiculture net cage, floating platform are comprised to the permanent moorings such as small-sized Zhang power leg formula platform, SPAR (cartridge type) platform, floating drum, buoy, light boat, floating dock and floating wharf have value of the utmost importance.
