Description
Technical field
The present invention relates to a kind of method of pouring pile hole, particularly a kind of method of square, rectangle bored pile hole.
Background technology
Along with the reform and opening-up fast development of national economy, domestic each port is to satisfy the requirement that boats and ships maximize, and builds the large-sized deep water berth one after another.The PORT OF TONGXHAN is to serve as a main model who builds the port at the aleuritic texture seashore with diaphragm wall sheet pile harbour, sheet-pile wharf structure as one of three big dock structure patterns has but run into great difficulty in the process of harbour deep waterization, maximization, mainly be that the sheet pile section is difficult to satisfy the moment of flexure requirement that deepwater wharf sharply increases.
General traditional way mainly contains:
1. the anti-grooving worker method that circulates of conduit gaslift
Traditional side's stake, rectangle stake pore-forming worker method are to have continued to use the proprietary anti-grooving technology that circulates of conduit gaslift of my company, have applied to after it is transformed a little in the construction of square stake, rectangle stake pore-forming.Operation equals pilot hole square, rectangle stake minor face size for boring one with single head diving drill machine or rotary drilling rig earlier, lay spray conduit, twin tip drill then, creep into along a direction, creep into finish after, change and to repair the traverse drill tool and the soil body that does not machine away is carried out the reaming cutting repair groove.Repair behind the trough end finish as stated above along other direction creep into, reaming repaiies the groove operation.Carry out scarfing cinder at last and change slurry, finish the drilling construction of whole stake.Its square or rectangle stake pore-forming operation and technological process are as follows:
Elder generation is construction one pilot hole in stake cross section, side, the anti-groover that circulates of lifting twin tip drill gaslift carries out construction operation along a direction in stake cross section, lifting impact reaming is repaiied the traverse drill tool and is carried out hole wall trimming construction operation, adjust the anti-groover construction direction that circulates of twin tip drill gaslift and carry out construction operation along the other direction in stake cross section, lifting is impacted reaming and is repaiied the traverse drill tool and carry out hole wall trimming construction operation.Form the pile body cross section that adheres to specification through above operation, the anti-groover that circulates of lifting twin tip drill gaslift carries out construction operation along a direction in stake cross section, lifting impact reaming is repaiied the traverse drill tool and is carried out hole wall trimming construction operation, adjust the anti-groover construction direction that circulates of twin tip drill gaslift and carry out construction operation along the other direction in stake cross section, lifting impact reaming is repaiied the traverse drill tool and is carried out hole wall trimming construction operation, forms the pile body cross section that adheres to specification through above operation.
Traditional handicraft trenching construction process: pilot hole construction, the construction in place of lifting pore-forming, through the twin tip drill pore-forming, hole for hoist is repaiied the construction in place of wall complete machine tool, the construction of finishing facility, lifting pore-forming facility tune construction, through the twin tip drill pore-forming, hole for hoist is repaiied the construction in place of wall complete machine tool again, the construction of finishing facility, change slurry through scarfing cinder, drilling construction finishes.

Because traditional worker's method transplants in continuous wall trench underground technology, and side's stake, rectangle stake exist the characteristics that quantity is big, the cross section is little, pile body is long.In square stake, rectangle pile driving construction, continue to use the construction technology of continuous wall trench underground, needing lifting repeatedly to lay spray conduit, twin tip drill and repair construction equipment such as traverse drill tool just can the side of finishing or the creeping into and cutting operation of rectangle stake pile body, therefore except that progress can not completely require, its hole quality also was difficult to guarantee.By statistical analysis as can be seen, accounted for half time of hoisting machine tool equipment, caused the pore-forming time longer, efficient is lower.
2. hydraulic grab method: the same with the method for hydraulic grab grooving, adopt hydraulic grab to carry out drilling construction square, the rectangle bored pile.Require the appearance and size of grab bucket consistent with the cross dimensions of stake, the grab bucket pore-forming is accomplished one-shot forming.Pore-forming efficiency is higher, but practical application is subjected to great limitation:
1. unit cost height: actual efficiency is compared with the unit cost and is caused operating expenses to improve, and construction cost strengthens.
2. bad adaptability: the stake section is ever-changing with structure stress, layout, and grab bucket must be supporting with it.Because of hydraulic grab bucket body processed complex, processing cost are bigger, the situation that makes it to adapt to a section variation is relatively poor.
3. less as the stake section, the monobucket body is grabbed the hole and is implemented relatively difficulty.
In order to solve the difficult problem of this long-term puzzlement marine traffic engineering circle, CCCC First Harbor Consultants Co., Ltd. is together with scientific research, monitoring, unit in charge of construction, design half blind type under owner's support energetically, blind type, separate discharging type sheet-pile wharf new construction, how to realize sheet-pile wharf structure deep water technology is broken through, " device of device for guiding tube reverse-circulation grooving method of underground continuous wall " (patent No.: patented technology 87102552.3) and " square; rectangle drilling pouring pile hole way-type drilling unit " (patent No.: 200720099780.5) patented technology of utilizing my company once to obtain, adopted the good rectangle of a large amount of stress performances in the structure, the bored pile of square cross-section, and research and develop a kind of job practices of adaptable sheet-pile wharf new structure type.
