Description
Technical field
The anti-daraf(reciprocal of farad) prestressed centrifugally pile tube of pick during the utility model relates to, during the square sunk pile device is mainly used in civilian and industrial infrastructure builds.
Background technology
The pile sinking device of existing prestressed centrifugally pile tube, side's stake mainly is applicable to the device that adopts hammering method and silent piling method, secondly is the device of boring extracting soil plunging and bored pile method.1, hammering method: when the stake diameter is bigger, can adopt hammering method during the no resident of periphery, but exist noise big, black smoke has vibration again during hammering, is a kind of pile-sinking method of high pollution.A lot of cities have forbidden in the center to use, and the hammer of present domestic maximum has only 10T simultaneously, and impact force is 1100 tons to the maximum.When bearing capacity can only change bored pile into greater than 1100 ton hours, so present high ferro and bridge pile foundation all are to select bored pile for use; 2, static pressure method: to be the deadweight that utilizes equipment be pressed into a kind of method in the soil to stake to static pressure method, but because equipment self-weight is bigger, higher to site requirements, it is limited to be pressed into power, the hydraulic pressure pile press of present domestic maximum is 800 tons, bearing capacity of single pile also can only be selected bored pile for use greater than just not adopting this method more than 400 tons.More than two kinds of pile-sinking method exist a kind of insurmountable problem, a large amount of stakes are beaten during (pressures) bury, and the soil body is outwards expanded, a large amount of soil compactions influence peripheral building, road and subway, tunnel and pipeline etc. can both produce cracking, displacement or the like.So can not beat (pressure) prestressed centrifugally pile tube in urban centre and subway limit, limit, tunnel and building compact district, side's stake can only be adopted bored pile.3, boring extracting soil plunging: promptly on former terrace, beat a hole with borrow equipment earlier, again stake is pressed in the hole, this method can adopt at northern area, because moisture content less in the soil, the hole can be shaped, but in southern Yangtze River Delta Area, water content is higher in the soil, draw the hole and just can't be shaped, stake just can't be beaten (pressure) and be gone into the also easy off normal of stake simultaneously.When stake was longer, boring extracting soil just was difficult to carry out, and the darkest at present fetching earth also can only be arrived about 30 meters; 4, another kind of pile foundation is the bored pile method: this method is a stake machine subdrilling hole on the ground, in the hole, irritate the steel bar concrete "forming column again, has the cost height, long in time limit, quality is difficult to not only guarantee and drilled pile but also have a large amount of mud to produce, mud is disposed and is difficult to, a large amount of mud all is disposed in the river, in the lake, in the sea, in the sewer, the size creek, sewer is stopped up by mud, government's annual cleaning sewer and creek mud expense are huge, cause great pollution, but at present on subway limit, urban centre, the river levee limit, the limit, tunnel, super highrise building, the high ferro foundation pile does not have soil compaction when promptly bearing capacity is big and can only adopt the bored pile method.
Summary of the invention
The utility model overcomes the deficiency of above several pile-sinking method, a kind of device that can replace present bored pile pile-sinking method fully, make the anti-daraf(reciprocal of farad) prestressed centrifugally of middle pick pile tube, the square sunk pile device that can use centrifugal pile tube, side's stake in the urban centre, this device has changed several pile-sinking method in the past, not directly stake to be beaten during (pressure) bury, but directly take out soil with auger at the center in stake when stake is pressed in the soil, and the soil that will take out reclaims by collection box simultaneously.
The utility model is to realize like this, the anti-daraf(reciprocal of farad) prestressed centrifugally pile tube of pick in a kind of, the square sunk pile device, comprise main frame, be installed in the hoist engine on the main frame, unit head, case fetches earth, pulley, wire rope, described unit head is installed on the main frame, described unit head upper end is equipped with pulley, described pulley is connected with wire rope, described wire rope is connected with hoist engine by the main frame top, described unit head below is connected with the drilling rod that fetches earth, described unit head lower end outer periphery is equipped with the screening soil suite, described screening soil suite lower end is connected with the case that fetches earth, described screening soil suite mainly plays and prevents that soil from falling down from the case that fetches earth, hiding soil suite simultaneously can stretch, the described case lower end of fetching earth is connected with pile cover, the described both sides, case lower end of fetching earth are respectively arranged with pulley, on the described pulley wire rope is installed, described wire rope is connected with hoist engine by the pulley that is installed on the main frame, centrifugal pile tube is laid in described pile cover lower end, side's stake, the described drilling rod that fetches earth passes fetch earth case and centrifugal pile tube, side's stake arrives bottom of device.The described unit head and the case that fetches earth can slide on main frame.
The utlity model has following remarkable advantages and beneficial effect:
1) use this device to have low cost, high benefit, noiselessness, free of contamination characteristics;
2) by the case that fetches earth soil is collected, embodied the civilization degree of construction, guarantee safety of construction, the feature of environmental protection;
3) with centrifugal pile tube, side's stake, no soil compaction, no mud have been realized in the time of by digging.
