Abstract

The utility model relates to a composite pile foundation. The composite pile foundation comprises an original pile foundation and high-pressure spinning-spray cement soil piles (9), wherein the original pile foundation comprises an original reinforced concrete column (3), an original reinforced concrete column base (2) and original reinforced concrete ground (4), the periphery of the original reinforced concrete column (3) on the original reinforced concrete ground (4) is provided with water drill holes (8), the water drill holes (8) are through the original reinforced concrete column base (2) from the original reinforced concrete ground (4), the lower portion of the original reinforced concrete column base (2) is the high-pressure spinning-spray cement soil piles (9), and elastic bodies are arranged between the high-pressure spinning-spray cement soil piles (9) and the original reinforced concrete column base (2). Gaps between the high-pressure spinning-spray cement soil piles (9) and the original reinforced concrete column base (2) can be filled with the elastic bodies, and accordingly the composite pile foundation is firmer.

Description

A kind of composite pile foundation
Technical field
The utility model relates to the foundation structure of building field, particularly a kind of composite pile foundation.
Background technology
Along with accelerating of Process of Urbanization Construction, the aging blocks engineering that renovates is a lot, so-called aging blocks renovate to reinforce and increase floor and include: the building cracking that irregular even sedimentation causes, high tower and the overage military service Qun building of inclination, and the built high building of change purposes urgent need increasing layer, be referred to as herein " aging blocks " (lower same).Prior art generally only limits to the strengthening reconstruction of the overground part of structure to aging blocks strengthening reconstruction, or after whole aging blocks are removed, carries out the transformation of underground pile foundation again; To the basis of former underground structure, technology or a blank on piling basis after aging blocks are not removed on indoor basis of not excavating.When can not meet superstructure, original underground base for post basis increases the supporting capacity after layer increase load, for making it meet bearing capacity demand, after utilizing existing technology just to only have existing building is removed and excavated, reconstruct again pile foundation, this improvement project amount is very large, this reforming mode of prior art, consumption wealth consumption power, has caused huge waste; How not destroying under the prerequisite of original base structure of aging blocks not removing aging blocks, descend over the ground base for post or the wall base to transform, is a great new research topic.
Utility model content
In order to make up the deficiencies in the prior art, fill up the blank of prior art, the purpose of this utility model is just: provide a kind of and do not removing aging blocks, do not destroy aging blocks original base, do not excavate the original ground of aging blocks, and the key new of the pile foundation of taking root after under aging blocks original base, specifically provides a kind of composite pile foundation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of composite pile foundation, comprises former pile foundation and high-pressure rotary-spray cement earth pile (9); Its Central Plains pile foundation comprises former reinforced concrete post (3), former steel concrete base for post (2), former steel concrete ground (4); The periphery of the former reinforced concrete post (3) on former steel concrete ground (4) is provided with water drilling boring (8), described water drilling boring (8) penetrates former steel concrete base for post (2) downwards from former steel concrete ground (4), the below of former steel concrete base for post (2) is high-pressure rotary-spray cement earth pile (9), between high-pressure rotary-spray cement earth pile (9) and former steel concrete base for post (2), is provided with elastic body.Elastomeric setting can be filled the gap between high-pressure rotary-spray cement earth pile (9) and former steel concrete base for post (2), makes composite pile foundation of the present utility model more firm.
Brief description of the drawings
Fig. 1 is Novel composite pile foundation structural representation;
Wherein, the code name of all parts in accompanying drawing is expressed as:
1, the 37 lime earth of backfill;
2, former steel concrete base for post;
3, former reinforced concrete post;
4, former steel concrete ground;
5, former steel concrete ground level;
6, former steel concrete base for post substrate design absolute altitude;
8, water drilling boring; 9, high-pressure rotary-spray cement earth pile.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
Embodiment 1: a kind of composite pile foundation, comprises former pile foundation and high-pressure rotary-spray cement earth pile (9); Its Central Plains pile foundation comprises former reinforced concrete post (3), former steel concrete base for post (2), former steel concrete ground (4); The periphery of the former reinforced concrete post (3) on former steel concrete ground (4) is provided with water drilling boring (8), described water drilling boring (8) penetrates former steel concrete base for post (2) downwards from former steel concrete ground (4), the below of former steel concrete base for post (2) is high-pressure rotary-spray cement earth pile (9), between high-pressure rotary-spray cement earth pile (9) and former steel concrete base for post (2), is provided with elastic body.Elastomeric setting can be filled the gap between high-pressure rotary-spray cement earth pile (9) and former steel concrete base for post (2), makes composite pile foundation of the present utility model more firm.
