Abstract

The utility model relates to a ribbed concrete composite pile core pipe. The static pressure pile adopted in the existing building construction field is required to be pressed into the ground, so that concrete columns with smooth surfaces are adopted and are pressed into soil under great pressure, during the compaction process, micro cracks can easily generate due to repeated compaction; therefore the quality and the service life of buildings are affected. The ribbed concrete composite pile core pipe comprises a reinforcement skeleton (1), concrete (2) wraps the reinforcement skeleton to jointly form a tubular pile body (3) with an annular cross section, inner concave ribs (4) or outer convex ribs (5) are arranged on the outer side of the tubular pile body. The ribbed concrete composite pile core pipe is used as pile foundation core material in concrete composite pile engineering.

Description

Concrete composite pile core pipe with ribbing

Technical field:

The utility model relates to a kind of building field house foundation that is used for to be built, with the concrete composite pile core pipe with ribbing that uses in pre-coremaking pipe and the construction technology that cast-in-place mode combines.

Background technology:

Existing building field adopts static pressed pile, need be pressed into ground,, adopt immense pressure to be pressed in the compacting process in the soil so adopt ganoid concrete column, punching press is easy to generate micro-crack repeatedly, influences the application life of construction quality and building.

Summary of the invention:

The purpose of this utility model provides a kind of more firm concrete composite pile core pipe of connection that can make between pile tube core body, plain cement layer and the soil layer.

Above-mentioned purpose realizes by following technical scheme:

Concrete composite pile core pipe with ribbing, its composition comprises: coat concrete around the cage of reinforcement, described cage of reinforcement and form the pile tube body of cross section for annular jointly, the external side of described pile tube has indent rib or outer fin.

Above-mentioned concrete composite pile core pipe with ribbing, described indent rib are corrugated indent rib or strip indent rib or point-like indent rib or helical form indent rib.

Above-mentioned concrete composite pile core pipe with ribbing, described outer fin are the outer fin of corrugated or the outer fin of strip or outer fin of point-like or the outer fin of helical form.

Beneficial effect:

1. the utility model has indent rib or outer fin, can effectively solve the bond strength of plain cement layer and core pipe, has strengthened side-friction force, has improved the vertical direction supporting capacity of single pile.

2. the utility model adopts corrugated rib, strip rib, point-like rib or helical form rib according to geology different situations and processing request, and the firm degree of pile tube is strengthened widely, has improved construction quality, has increased the application life of building.

3. the utility model building costs is low, fastness good, can batch production production, can repair before using, and can reach any requirement of building.

4. use this product lens intensity good, at reinforcing bar with do not have under the concrete carrying of compression shock damage, be aided with indent rib or outer fin, by plain cement stake core and the earth are combined closely, forming new best basic schema, is to two kinds of existing in the world pile body technologies--a major transformation of-static pressed pile and monobloc cast pile constructing process.
