Abstract
The utility model relates to a composite foundation with PTC perforated tubular piles with caps, comprising PTC perforated tubular piles with through holes and pile caps. The composite foundation with the PTC perforated tubular piles with the caps is characterized in that the top ends of the PTC perforated tubular piles provided with the through holes are connected with the pile caps, and the external surfaces of the pile caps are cushioned with broken stones to form a broken stone cushion layer. The composite foundation with the PTC perforated tubular piles with the caps has the advantages that the PTC tubular piles are adopted in order to utilize the water collecting function of cavities of the tubular piles, and the squeezing effect of adjacent piles can be effectively reduced during the construction of the perforated tubular piles, thereby cleaning the environment; and the perforated tubular piles also have the advantage of saving energy.
Description
Technical field
The utility model relates to a kind of pipe pile composite foundation, relates in particular to a kind of band cap PTC type perforated pipe pile composite foundation.
Background technology
At present during the existing pipes pile driving construction, particularly the hammer piling mode produces soil compaction effect and excess pore water pressure, very easily causes adjacent stake skew, even broken pile.PTC type pile tube is used for the deep soft soil foundation treatment project, and main purpose is the distortion of control foundation settlement, improves bearing capacity of foundation soil, and pile tube self bearing capacity is not a subject matter.The main cause that the foundation settlement distortion produces is because the discharge of soil body mesopore water under the outer load effect.For deep soft soil foundation engineerings such as speedway, high-speed railway, road in airport, control its foundation settlement distortion, mainly be meant the control settlement amount after construction, be that its settlement amount after construction is controlled in the critical field.If produce more settling amount as far as possible in construction periods such as embankment, dykes and dams, promptly produce the foundation settlement deflection of construction period, with the discharge as much as possible of native mesopore water, reduce the water content of soil, then its settlement amount after construction will be reduced and will be controlled in the critical field of settlement amount after construction, reach processing intent.Because the native rigidity of stake differs greatly, causes a top stress too concentrated easily, thrusts distortion in the generation, forms native doming effect.
Summary of the invention
The purpose of this utility model is to provide a kind of band cap PTC type perforated pipe pile composite foundation, this composite foundation is provided with pile cover, with homogenizing stake top stress, thrust distortion on reducing, certain thickness rubble mattress layer (can add steel mesh reinforcement) is set on pile cover again, forms band cap PTC type perforated pipe pile composite foundation.
The utility model is achieved like this, it includes PTC pile tube, pile cover to perforation, it is characterized in that having the top to the PTC pile tube of perforation to be connected with pile cover, and the pile cover external surface is lined with rubble and forms hardcore bed.
Be connected with steel mesh reinforcement in the described pile cover.
Described by the PTC pile tube of boring a hole is formed by the cylindrical tube pile lining with to perforation, the cylindrical tube pile lining has several from top to bottom to perforation.
Technique effect of the present utility model is: adopting the PTC pile tube that has perforation is the polywater effect that utilizes the pile tube cavity, can effectively reduce adjacent stake soil compaction effect during the ported sub pile driving construction, cleaning ambient; Pile tube with holes also has energy-conservation advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional drawing of the utility model to perforation PTC pile tube.
In the drawings, 1, have PTC pile tube 2 to perforation, pile cover 3, steel mesh reinforcement 4, cylindrical tube pile lining 5, to bore a hole 6, rubble
The specific embodiment
As shown in Figure 1, have the top of PTC pile tube 1 to perforation to be connected with pile cover 2, pile cover 2 external surfaces are lined with rubble 6 and form hardcore beds.Have the pile tube diameter of PTC pile tube of perforation is selected for use 450mm, as shown in Figure 2,5 form by cylindrical tube pile lining 4 with to boring a hole by PTC pile tube 1 perforation, cylindrical tube pile lining 4 has several from top to bottom to boring a hole 5, every linear meter(lin.m.) is provided with 2 to perforation, pile cover size 1.5m * 1.5m * 0.4m, and the pile cover arrangement of reinforcement designs by the steel concrete requirement, in order to strengthen pile cover intensity, can in pile cover 2, establish steel mesh reinforcement 3.During construction, be provided with PTC pile tube 1 in the soft foundation to perforation, no matter be in the construction period, still in the construction intermittent phase, generation, development and dissipation along with excess pore water pressure, water in soil can enter to the perforation PTC pile tube 1 in, if having to the perforation 1 week of PTC pile tube run into the mucky soil environment, also can by to bore a hole 5 enter to the perforation PTC pile tubes 1 in.If water is many in the construction period hole, then can take the mode of drawing water that it is got rid of.Along with water level in the hole reduces, water in soil can infiltrate in the pile tube again, makes the water content of soil be able to further reduction, and the shear strength of soil improves, and bearing capacity of foundation soil strengthens.
