Abstract
The invention discloses a different-diameter reinforcement and replacement type equal-length plain concrete pile composite foundation. The different-diameter reinforcement and replacement type equal-length plain concrete pile composite foundation is formed by intersecting large-diameter plain concrete piles, and small-diameter plain concrete piles which have the equal length; the large-diameter plain concrete piles are arranged in a soft area of which the geological conditions are nonuniform; the small-diameter plain concrete piles are arranged in a hard area; and the large-diameter plain concrete piles and the small-diameter plain concrete piles which have the equal number are arranged in an area of which the geological conditions are uniform at equal distances, so the requirement of the whole foundation settlement can be met. Under the condition of meeting the bearing capacity of the foundation, the aim of controlling the whole foundation settlement can be fulfilled by changing concrete piles with different sizes, so the safety and stability of a building can be improved, the using amount of pile materials is reduced, and construction cost is saved.
Description
Technical field
The present invention relates to a kind of the realm of building construction, is that a kind of different-diameter is reinforced and the isometric plain concrete pile composite foundation of displaced type specifically.
Background technology
Extensively adopt plain concrete pile as the ground load-carrying members at the realm of building construction at present; Prevent the sinking of ground of building; It evenly is arranged on ground basic unit face with isometric isodiametric plain concrete pile, and the upper end of plain concrete pile is connected with the bearing surface of building.Bearing surface is passed to its load that receives on the coupled plain concrete pile that connects; And then prevent sinking of ground; Owing to then make that owing to it has adopted the concrete pile of same diameter the cost cost of ground is higher in the zone uniformly at geological conditions; Also be unfavorable for reducing engineering cost, and, make in the uneven sedimentation of construction area internal area geological conditions different because this structure adopts is the plain concrete pile of same diameter; Wherein the sagging degree in softer location can be strong; And can be more weak relatively in the sagging degree of hard location, thereby be prone to make the ground of building that differential settlement takes place, with safety that directly influences building and reliability.
Summary of the invention
In order to solve the deficiency of prior art structure; The present invention provides a kind of different-diameter to reinforce and the isometric plain concrete pile composite foundation of displaced type, is guaranteeing can to improve the safety and the stability of building under the condition that bearing capacity of foundation soil satisfies; Reduce stake material consumption simultaneously, practiced thrift construction costs.
The present invention realizes through following technical proposals: major diameter plain concrete pile and minor diameter plain concrete pile cross-distribution by length is identical are formed; Soft location in the uneven construction area of geological conditions is provided with the major diameter plain concrete pile; In hard location the minor diameter plain concrete pile is being set then, at geological conditions construction area equivalent equidistance large and small plain concrete pile arranged in a crossed manner then relatively uniformly.The present invention to improve the safety and the stability of building, has reduced stake material consumption guaranteeing to reach the purpose of controlling the ground bulk settling through the concrete pile that changes different sizes under the condition that bearing capacity of foundation soil satisfies simultaneously, practices thrift construction costs.
The invention has the beneficial effects as follows: not only can play good anti-settling effect, and can effectively prevent the differential settlement that ground is local, improve the safety and the stability of building; Reduced stake material consumption simultaneously, practiced thrift construction costs, product structure is simple; Easy construction is convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a plan structure sketch map of the present invention.
Fig. 2 is a cross-sectional view of the present invention.
Fig. 3 implements state plan structure sketch map for the 2nd kind of the present invention.
Code description among the figure: 1 major diameter plain concrete pile; 2 minor diameter plain concrete piles; The softer zone of 3 geology; 4 geology are than the territory, hard area.
The specific embodiment
Like Fig. 1, shown in Figure 2; The present invention is made up of length identical major diameter plain concrete pile (1) and minor diameter plain concrete pile (2) cross-distribution, in the zone of geological conditions distribution uniform with major diameter plain concrete pile and minor diameter plain concrete pile equidistance equivalent distributed and arranged.Guaranteeing under the condition that bearing capacity of foundation soil satisfies; Adopt this different-diameter to reinforce the purpose that reaches control ground bulk settling with the isometric plain concrete pile composite foundation of displaced type; Can reduce stake material consumption, practice thrift cost, thereby reach the purpose that reduces construction costs.
As shown in Figure 3; For preventing the differential settlement of constructure ground, major diameter plain concrete pile (1) is located to be provided with in the softer zone of the geological conditions in construction area (3), locates then to be provided with minor diameter plain concrete pile (2) at geological conditions than territory, hard area (4); The major diameter plain concrete pile is because its cross section can increase resistance more greatly; And its contact surface with rock-soil layer is also big a lot of than Small Diameter Pile, also can increase friction, thereby the bearing surface of building is played effective supporting; Thereby make the ground in softer zone and realize helping protecting the safety of building by whole uniform settlement synchronously than the ground in territory, hard area.
Claims (3)
1. a different-diameter is reinforced and the isometric plain concrete pile composite foundation of displaced type, it is characterized in that: be made up of major diameter plain concrete pile and minor diameter plain concrete pile cross-distribution.
2. a kind of different-diameter according to claim 1 is reinforced and the isometric plain concrete pile composite foundation of displaced type, and it is characterized in that: the soft location in construction area is provided with the major diameter plain concrete pile, in hard location the minor diameter plain concrete pile is set then.
3. a kind of different-diameter according to claim 1 is reinforced and the isometric plain concrete pile composite foundation of displaced type, it is characterized in that: at geological conditions construction area equivalent equidistance large and small plain concrete pile arranged in a crossed manner then relatively uniformly.
