Fig. 2 is the used packed prefabricated extruding-enlarging pile construction method sketch map of building of a kind of concrete of second embodiment of the present invention.
The specific embodiment
As of the present invention as Fig. 1 to shown in first embodiment, main purpose is to introduce the packed pouring construction method of Small Diameter Pile hole concrete.In first embodiment first step of the present invention, confirm the stake position according to design working drawing, accomplish stake hole (1) through soil digging or drilling construction, as shown in Figure 1.Thereby accomplish first embodiment first step of the present invention, got into for second step.Because of stake hole (1) diameter is little, be difficult to adopt tremie method to carry out concrete spouting, can adopt like the packed pouring construction method of Small Diameter Pile of the present invention hole concrete and carry out the concrete spouting construction.In this step, the concrete that does not condense (2) to be packed in the bag as shown in Figure 1 (3), bag (3) can be to be made by intensive wire gauze; The sectional dimension of bag (3) should be less than the sectional dimension of stake hole (1); For the ease of construction, can also pack bag (3) into before in the concrete that does not condense (2), place diameter to be slightly less than the tubular structure (4) of a hole (1) in bag (3); The concrete (2) of in bag (3), packing into and not condensing then, tubular structure (4) bottom is with piston (5) shutoff.Thereby accomplish second step of first embodiment of the invention, got into for the 3rd step.In this step; Only need that the concrete that does not condense (2) in bag (3) and the bag (3) is put into a hole (1) and get final product,, bag (3) has been packed in the tubular structure (4) as in second step; Then only need with tubular structure (4) move to a hole (1) directly over; Draw back piston (5), under action of gravity, just can the concrete that not condense (2) of bag (3) and interior dress thereof successfully be inserted in the hole (1).Because of protection and constraint at the concrete that does not condense (2) outside marsupial (3); The concrete that does not condense (2) can not occur phenomenons such as segregation, hole clipping in the process that falls; As in stake hole (1) water being arranged, in the process that the concrete that does not condense (2) is falling, can not change component because of washing away of water.Thereby accomplish the 3rd step of first embodiment of the invention, got into for the 4th step.As going on foot the 3rd, the amount unmet designing requirement of the concrete that does not condense (2) that once pours into then can continue to pour into the concrete (2) that does not condense with the 3rd step through repeating the second above-mentioned step, till capacity.Thereby accomplish the 4th step of first embodiment of the invention, got into for the 5th step.In this step, can through tamp, vibrate, mode such as knocking is closely knit with the concrete that does not condense (2) in stake hole (1), promptly accomplished for the 5th step, thereby accomplish the packed pouring construction method of Small Diameter Pile of the present invention hole concrete.
As of the present invention as Fig. 2 to shown in second embodiment, main purpose is to introduce the packed prefabricated extruding-enlarging pile construction method of building of a kind of concrete.In the first step of present embodiment, confirm the stake position according to design working drawing, the mode of preformed pile (6) through piling or piling that the bottom is connected with the hollow of stake plug (7) sinks to desired depth, utilizes the preformed pile hollow part as stake hole (1), accomplishes a stake hole (1) construction.Thereby accomplish the first step of present embodiment, got into for second step.In this step, be similar to first above-mentioned embodiment, with the concrete that does not condense (2) pack into the cross section less than cross section, stake hole (1) the bag (3) in.Thereby accomplish second step of present embodiment, got into for the 3rd step.In this step, utilize external diameter to insert in the stake hole (1) less than the Pile feeder in above-mentioned stake hole (1), adopt the mode of knocking or static pressure that stake plug (7) is pressed in the soil body; Thereby remove stake plug (7); And bottom the preformed pile (6) of hollow, form hole, then the concrete that does not condense (2) in the bag (3) of packing in above-mentioned second step is positioned in the hole (1), under the constraint of bag (3) together with bag (3); The concrete that does not condense (2) in the bag (3) will be smoothly through stake hole (1); Even be full of underground water in stake hole (1), the component of the concrete that does not condense (2) will remain unchanged, and disaster such as concrete disintegration can not take place.Thereby accomplish the 3rd step of present embodiment, got into for the 4th step.In this step, judge earlier whether the amount of the concrete (2) that once perfusion is not condensed can meet the demands, not enough like the amount of pouring into, then repeated for second step and the 3rd step, reach requirement like the amount of pouring into, then do not need this step.Thereby accomplish the 4th step of present embodiment, got into for the 5th step.In this step, through above-mentioned stake hole (1), utilize the Pile feeder extruding above-mentioned concrete that do not condense (2) of external diameter less than stake hole (1), the above-mentioned concrete that does not condense (2) is clamp-oned in the soil body of preformed pile (6) bottom of hollow, form a stake end expanding reach (8).Accomplish the 5th step of present embodiment, got into for the 6th step.In this step; Main according to the amount of the concrete that does not condense (2) that pours into and the needs of stake end expanding reach (8) enlarging amplitude; Determine whether the 4th step and the 5th step of repetition; Until a construction of accomplishing stake end expanding reach (8), meet the demands like the reaming amplitude of expanding reach at the bottom of the stake (8), then do not need this step.Thereby accomplished the packed prefabricated extruding-enlarging pile construction method of building of concrete of the present invention.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
