Description
Technical field
The utility model relates to a kind of offshore platform spud leg high-pressure water-flushing device, washes away the obstructions such as surrounding soil when being applied to offshore platform pile pulling.
Background technology
At present, offshore platform spud leg mostly is steel-structured circular cylindricality or square column type, and spud leg bottom is according to fender pile boots, external geology is generally without the need to flushometer, and coastal area of china geology, clay layer is thicker, and operating location is different, soil body proterties is different, complex formation, and geology is loosened, mud is entered very dark during platform pitching pile, and pitching pile destroy the soil body again pulping back-silt, form new attachment soil stabilization on spud leg, after long-time consolidation, have very large intensity.When shoe enters mud chin-deep, pile extraction resistance greatly exceed the limit pile pulling ability that platform structure can bear, so resistance reduces when pile pulling needs to impel pile pulling by bath or additive method, realizes pile pulling efficiency high.It is the flushing system of the inner take-over type of spud leg that general platform can design, but flow and pressure are difficult to the soil body that fast flush goes shoe to adhere to, because pressure is too small, sometimes during pitching pile, be easy to gambling plug outlet pipe shower nozzle, and operating difficulties, is difficult to the effect reaching high speed pile pulling.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of offshore platform spud leg high-pressure water-flushing device is provided, possesses very large discharge and pressure, adopt spud leg outer tube directly to drain into spud leg top, and directly enter water from spud leg top and wash away shoe, form very large impact force, make it adhere to soil body viscosity to weaken, reduce the frictional force of spud leg, shoe and the soil body, thus reduction pile pulling pressure, finally reach pile pulling rapidly and efficiently.。
The purpose of this utility model is achieved through the following technical solutions: a kind of offshore platform spud leg high-pressure water-flushing device, comprise shoe and spud leg, spud leg is provided with wedge bracket, deck in wedge bracket is provided with high-pressure pump, one end of high-pressure pump is connected with water suction hard tube, water suction hard tube is connected with suction water pipe, thick water filter is provided with between water suction hard tube and suction water pipe, the other end of high-pressure pump is connected with screw down nonreturn valve by inlet hose, screw down nonreturn valve is connected with by four-way connection pipeline and two outlet pipes that has safety valve respectively, every root outlet pipe is equipped with stainless steel ball valve, two outlet pipes all communicate with high pressure delivery hose, high pressure delivery hose spirals on hysteresis two-way water pipe reel, water pipe reel is placed in the top of wedge bracket, the delivery port of high pressure delivery hose is placed in spud leg top and connects with outlet pipe in stake, the interior outlet pipe of stake ejects outlet pipe at the bottom of water pipe and boots with the boots in shoe and communicates, boots eject outlet pipe at the bottom of water pipe and boots and are connected with the shower nozzle at the bottom of shoe top showerhead and boots respectively.
Further improvement of the utility model is: the top of spud leg is provided with bracket, and the connector of outlet pipe in high pressure delivery hose and stake held by bracket.
The utility model compared with prior art has the following advantages: shoe transformation is very little, ensures the intensity of himself; Hydraulic pressure is relatively very large, and stream there's plenty of it, is enough to wash away spud leg, the shoe soil body; Adopt hysteresis two-way water pipe reel, can automatic deploying and retracting high-pressure water pipe by the effect of magnetic hysteresis shaft coupling, water pipe leads directly to spud leg top, and water is converted into impact kinetic energy by high potential energy.System architecture is simple, and the continuable bath when pile pulling, without the need to considering the position of spud leg movement; The tubular type that connects is washed by water, and decreases the resistance of interface backflow, simply easy to operate; According to demand during pile pulling, the bath pressure at the bottom of boots top and boots and flow can be regulated, reach and efficiently wash away the shoe attachment soil body, reach quick pile pulling.
