Abstract

The present invention relates to a special concrete pipe pile for construction foundation engineering, which belongs to the field of concrete pipe pile manufacture. The special concrete pipe pile comprises a pile body, wherein reinforcing ribs are arranged in the pile body, and longitudinal convex ribs are arranged on the outer wall of the pile body. The present invention has the advantage that the design of the longitudinal ribs on the outer wall of the pipe pile effectively enlarges the effective supporting areas of the whole pipe pile, enhances the bearing capacity of the pipe pile, effectively reduces the pile pressing depth of the pipe pile and greatly lowers the pile pressing difficulty and the pile pressing cost of the pipe pile under the condition of keeping the bearing pressure of the pipe pile unchanged.

Description

Bar shape tubular pile

Technical field:

The present invention relates to a kind of building foundation engineering concrete special pile tube, belong to concrete tubular pile and make the field.

Background technology:

Notice of authorization CN2611433Y, title " pretensioning prestressed concrete abnormity pile tube ", this abnormity pile tube comprises the stake body that extends vertically, be provided with reinforcing rib in the stake body, be provided with the ring projection that radially becomes big at intervals on the stake body, the stake body between the ring projection is cylindrical.Its weak point: the ring projection on the stake body, when piling, because the ring of projection can only be depressed soil pressure is enforceable on the stake body, and can't make soil form the motion that oppositely makes progress, therefore the last earth density around the stake body between two rings can't increase, can't form strong support to the ring of projection, does not reach the purpose of raising pile tube bearing pressure.

Summary of the invention:

Purpose of design: avoid the weak point in the background technology, design and a kind ofly not only can increase pile tube pressure-bearing Area of bearing effectively, and can improve the bar shape tubular pile of pile tube bearing pressure by this Area of bearing effectively.

Design scheme: to achieve these goals, the present invention is on the basis of existing special-shaped pile tube, on the outer wall of pile body, be provided with the muscle of vertical projection, this muscle can be the helical raised muscle, it can be the herringbone raised ribs, it can be latticed raised ribs, it can be the rhombus raised ribs, it can be 1 font raised ribs, the function of raised ribs is: the one, can enlarge effective Area of bearing of whole pile tube effectively, improve the supporting capacity of pile tube, when pile tube is forced to be pressed into when underground, the earth of pile tube periphery strongly upwards turns over the raised ribs on the bar shape tubular pile wall is formed huge upwards support force (F=-F), has greatly improved the bearing pressure of pile tube; The 2nd, in order to improve the compressive resistance of muscle shape tubulose protrusions muscle, be provided with reinforcing rib in the spiral bar of projection on the pile tube wall, this reinforcing rib is set in the helical raised muscle not only can improves bar shape tubular pile integral intensity and its forward, backward bearer pressure effectively, and guaranteeing under the constant situation of pile tube bearing pressure, can reduce the degree of depth of pile tube piling effectively, reduce the piling difficulty and the piling cost of pile tube widely.

Technical scheme 1: bar shape tubular pile, it comprises pile body (1), is provided with reinforcing rib (3) in the pile body (1), the outer wall of pile body has the muscle of vertical projection.

Technical scheme 2: a kind of bar shape tubular pile as claimed in claim 1 has the helical form muscle (2) of projection and is overall structure with pile tube (1) on the outer wall of pile body (1).Helical form muscle (2) has more than 1 or 2 or 2; Helical form muscle (2) is circular arc or curved or be convex-concave arc or rectangular boss shape.

Technical scheme 3: a kind of bar shape tubular pile as claimed in claim 1 has 1 font muscle (7) of the latticed muscle (6) of the rhombus muscle (5) of the herringbone muscle (4) of projection or projection or projection or projection and is overall structure with pile tube (1) on the outer wall of pile body (1).

The present invention compares with background technology, the design of longitudinal rib on the pile tube outer wall, not only enlarge effective Area of bearing of whole pile tube effectively, improve the supporting capacity of pile tube, and guaranteeing under the constant situation of pile tube bearing pressure, can reduce the pile tube piling degree of depth effectively, reduce the piling difficulty and the piling cost of pile tube widely.
