Abstract
The present invention relates to a reaming and grouting pile and a forming method. The reaming and grouting pile comprises a steel reinforced concrete body composed of a reinforcing cage and concrete, wherein the reaming and grouting pile also comprises a grouting pipe; the grouting pipe is arranged on the reinforcing cage, and a chassis is arranged at the bottom of the steel reinforced concrete body; cement mortar is injected in the steel reinforced concrete body and the outer surface of the chassis. The forming method of the reaming and grouting pile comprises driving a pile hole, expending the chassis, putting the reinforcing cage and the grouting pipe, filling the concrete, and injecting the cement mortar after the reaming and grouting pile is formed. The present invention has the advantages of high bearing capacity, no soil at a pile bottom, thin soil skin at the side of the reaming and grouting pile, raw material saving, etc.
Description
The present invention relates to a kind of base-extending deposited pile and forming method, it belongs to a kind of cast-in-place concrete pile pile foundation and forming method.
The well-known linear cast-in-place concrete pile bearing capacity of ordinary straight is low, the sharp loosened soil of stake is difficult to handle, mud off pore-forming technique stake side mud skin depth frictional resistance can not play one's part to the full, and therefore exists shortcomings such as bearing capacity is low, stake quantity is many, stake end loosened soil is thick, the pile side friction loss is big, the mud emission amount is big.
The purpose of this invention is to provide a kind of bearing capacity height, stake does not have the base-extending deposited pile and the forming method of thin not only economy of loosened soil, stake side mud skin but also easy construction the end.
The object of the present invention is achieved like this: this base-extending deposited pile, it comprises the reinforced concrete soil body, Grouting Pipe and the cement paste that are made of reinforcing cage and concrete, Grouting Pipe is located on the reinforcing cage, wherein: the method that is provided with a mechanical squeezed shaping of usefulness in the bottom of the reinforced concrete soil body is configured as the conical chassis of annulus, and the external surface on concrete bodies and chassis is marked with cement paste.
The method of above-mentioned base-extending deposited forming pile is made up of following step:
(1), use boring machine to break into a hole in the position in needs piling hole by designing requirement;
(2), use can be in the stake hole squeezed conical chassis of mechanical squeezed one-tenth annulus;
(3), Grouting Pipe and reinforcing cage colligation together, put into a hole;
(4), concrete perfusion;
(5), concrete promptly forms base-extending deposited pile for the stake end or the slip casting of stake side by Grouting Pipe after reaching designing requirement intensity.
Because the present invention combines squeezed expansion bottom technique and post grouting process, make base-extending deposited pile not only can expand end size by designing requirement control, and grouting process eliminate by the modes such as expansion, compacted and splitting densification of oozing of slurries at the bottom of loosened soil and sediment and all inherent shortcomings of stake, improve stake pedosphere face, make the soil body in the Zhou Yiding scope obtain reinforcing.Grouting process not only makes actual pile body frictional resistance conform to the design frictional resistance, and makes the stake end because of loosened soil and the sediment that construction technology causes obtains reinforcing, and gives full play of the end that expands the chassis and makes usefulness.Therefore the present invention compares with background technology, has bearing capacity height, a stake end and does not have advantages such as loosened soil, a stake side mud skin approach, save material.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional drawing among Fig. 1.
As depicted in figs. 1 and 2, base-extending deposited pile in the present embodiment, it comprises a reinforced concrete soil body that is made of reinforcing cage 1 and concrete 3, wherein it also comprises Grouting Pipe 2, Grouting Pipe 2 is located on the reinforcing cage 1, the method that is provided with a mechanical squeezed shaping of usefulness in the bottom of the reinforced concrete soil body is configured as the conical concrete of annulus chassis 5, and the external surface on concrete bodies and chassis 5 is marked with cement paste 4.
The shape on above-mentioned chassis can also be with ramming expansion, explosive expansion, digging and expand the method that is shaped and be configured as square, circular or irregular shape.
The method of above-mentioned base-extending deposited forming pile is:
(1), use boring machine to break into a hole in the position in needs piling hole by the engineering design requirement;
(2), use can be in the stake hole squeezed conical chassis of mechanical squeezed one-tenth annulus;
(3), Grouting Pipe and reinforcing cage colligation together, put into a hole;
(4), concrete perfusion;
(5), concrete promptly forms base-extending deposited pile for the stake end or the slip casting of stake side by Grouting Pipe after reaching the engineering design desired strength.
The machinery that also can use and ram expansion, explosive expansion, dig expansion in the 2nd step of above-mentioned forming method rams expansion, explosive expansion, digs and expand squarely, circle or difform chassis.
