Abstract
The utility model discloses an anti-sidesway large-diameter composite cast-in-place concrete pile. The composite cast-in-place concrete pile comprises a pile body and is characterized in that the pile body comprises a main pile body, a plurality of side pile bodies are arranged on the outer surface of the main pile body and fixedly connected with the main pile body. According to the anti-sidesway large-diameter composite cast-in-place concrete pile, a horizontal sidesway resistant function is realized through vertical bearing of the main pile body and combined action of the side pile bodies, so that the comprehensive bearing capacity of a single pile is improved greatly, central lines of the side pile bodies and the central line of the main pile body are intersected at one point and the included angles are equal, that is, the side pile bodies are located at the same height of the main pile body and are uniformly distributed, accordingly, stress of the side pile bodies is uniform, and the horizontal sidesway resistant function can be realized effectively.
Description
Technical field
The utility model relates to the pile foundation engineering field of civil engineering, and in particular, the utility model relates to a kind of anti-sidesway major diameter composite concrete castinplace pile.
Background technology
At present, when common filling pile carries out consolidation process to natural soft soil foundation, aspect vertical bearing capacity, there is larger advantage, aspect the anti-sidesway of level, there is larger deficiency.On the other hand, although Trees with Small Diameters pile Lateral resisting ability is better, vertical bearing capacity is less.This has fettered the development that sidesway, vertical bearing capacity is all had to the Foundation Design such as embankment, bank slope, sea wall of strict demand to a certain extent.
Utility model content
The purpose of this utility model is to solve existing above-mentioned problem, provides a kind of and can resist sidesway major diameter composite concrete castinplace pile.
For realizing above object, the technical solution of the utility model is a kind of anti-sidesway major diameter composite concrete castinplace pile, comprises pile body, it is characterized in that, described pile body comprises main pile body, and described main pile body external surface is provided with some side pile bodies, and described side pile body is fixedly connected with main pile body.By the acting in conjunction of the vertical carrying of main pile body and side pile body, play the flat anti-sidesway effect of water resistant, greatly improved single pile comprehensive load capacity.
As preferably, described side pile body is evenly distributed on main pile body external surface, and the described center line of side pile body and the center line of main pile body all intersect at same point, and the described center line of side pile body is all identical with the angle of the center line of main pile body.The center line of side pile body center line and main pile body all intersects at a point, and angle is identical, illustrates that side pile body is positioned at the unified height of main pile body, and is uniformly distributed, and makes like this stressed even of each side pile body, can effectively play the effect of the flat sidesway of water resistant.
As preferably, the described center line of side pile body and the angular range of the center line of main pile body are 10 degree ~ 60 degree.Angle is too little or angle is too large, and the effect of playing the flat sidesway of water resistant is little, can not meet some requirement.
As preferably, the identical length of described side pile body with.The identical length of side pile body is same, convenient construction, and easily moulding, and quality can access effective assurance.
As preferably, described main pile body inside is provided with main reinforcement cage, and described side pile body inside is provided with side reinforcing cage, and described side reinforcing cage is fixedly connected with main reinforcement cage, described main reinforcement cage is fixedly connected with main pile body, and described side reinforcing cage is fixedly connected with side pile body.The side reinforcing cage of the main reinforcement cage of main pile body inside and side pile body inside can play the intensity that increases pile body, has increased to a certain extent the application life of pile body.
The utlity model has following beneficial effect: by the acting in conjunction of the vertical carrying of main pile body and side pile body, play the flat anti-sidesway effect of water resistant, greatly improved single pile comprehensive load capacity, the center line of side pile body center line and main pile body all intersects at a point, and angle is identical, illustrates that side pile body is positioned at the unified height of main pile body, and be uniformly distributed, make like this stressed even of each side pile body, can effectively play the effect of the flat sidesway of water resistant.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
1, pile body, 2, main pile body, 3, side pile body, 4, main reinforcement cage, 5, side reinforcing cage.
The specific embodiment
Below in conjunction with specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described:
Embodiment: anti-sidesway major diameter composite concrete castinplace pile (seeing accompanying drawing 1), comprise pile body 1, described pile body 1 comprises main pile body 2, described main pile body 2 external surfaces are provided with two side pile bodies 3, described side pile body 3 is one-body molded by cast with main pile body 2, described side pile body 3 is evenly distributed on main pile body 2 external surfaces, the center line of described side pile body 3 and the center line of main pile body 2 all intersect at same point, the center line of described side pile body 3 is all identical with the angle of the center line of main pile body 2, the angular range of the center line of described side pile body 3 and the center line of main pile body 2 is 10 degree ~ 60 degree, the angle that this castinplace pile adopts is 36 degree, the identical length of described side pile body 3 is same, described main pile body 2 inside are provided with main reinforcement cage 4, described side pile body 3 inside are provided with side reinforcing cage 5, described side reinforcing cage 5 is welded and fixed with main reinforcement cage 4, described main reinforcement cage 4 is fixedly connected with main pile body 2, described side reinforcing cage 5 is fixedly connected with side pile body 3.
Anti-sidesway major diameter composite concrete castinplace pile, pile body is comprised of vertical main pile body and oblique side pile body two parts.Described main pile body is vertical large-diameter concrete castinplace pile, and diameter is greater than 0.8m conventionally, mainly plays vertical carrying effect; Described side pile body is oblique minor diameter cast-in-place concrete pile, and diameter is conventionally between between 0.1m to 0.3m, and this example is got 0.2m, mainly plays the effect of limit levels sidesway.
In this example, main pile body total length is got 10m, diameter 1m.Total symmetrical 2 of side pile body, single Zhi Changdu 5m, diameter is got 0.2m.The major-minor pile body node centre of form apart from stake at the bottom of 8m.
