Abstract
The utility model provides a composite foundation of a mixture of a port engineering riprap foundation bed and underwater non-dispersion concrete. The composite foundation is located on an underwater mudstone foundation. The underwater non-dispersion concrete is adhered to the surface layer of the mudstone foundation. The underwater non-dispersion concrete is tightly mixed with bed rock blocks through the self-leveling characteristic of the underwater non-dispersion concrete and bed rock cracks are covered and sealed. The bed rock blocks thrown before the underwater non-dispersion concrete solidifies are embedded in the concrete so that the composite foundation of a gravity type structure can be formed. The composite foundation of the mixture of the port engineering riprap foundation bed and the underwater non-dispersion concrete has the advantages that besides the fact that the composite foundation satisfies the requirements of a foundation of a common gravity type structure, the contact between water and a mudstone layer is blocked by the composite foundation, the phenomena that mudstone is softened and argillization occurs under long-term action of water are avoided, and the negative influence brought to the stability of the gravity type structure and the bearing capacity of the foundation of a port are avoided.
Description
Technical field
The utility model belong to harbour or coastal engineering build in the composite foundation that mixes with non-dispersible underwater concrete of a kind of port works riprap foundation of the gravity structure on the mud stone ground under water.
Background technology
The basis is the important component part of harbour or coastal engineering building, and its major function comprises: the external force that superstructure is transmitted is diffused in a big way the ground, to reduce the sedimentation of foundation stress and building; The protection ground is avoided the scour of wave and current; The leveling basal plane is convenient to building by laying bricks or stones or installing of superstructure.One of decisive factor of basis pattern is the character of ground.
Ground in harbour or the coastal engineering construction mainly can be divided into two kinds of rock foundation and non-rock foundations.Itself is firm mostly, bearing capacity large for rock foundation, foundation settlement is very little, generally can adopt riprap foundation or directly build or install superstructure in the above by laying bricks or stones behind the leveling scar.But then can not select above-mentioned basis for the mud stone ground.For immersion namely take a stand in fully disintegration, the water soon for unsettled mud stone cannot be as bearing stratum, must removing.Although can be used as bearing stratum for statement in water for mud stone stable, that bearing capacity of foundation soil is higher, but common basis can not be with mud stone and water isolation, so that mud stone produces softening and argillization phenomenon under the water long term, harbour gravity structure stability and supporting capacity are produced larger adverse effect.
Summary of the invention
The purpose of this utility model provide that a kind of port works riprap foundation mixes with non-dispersible underwater concrete composite foundation, this composite foundation can closely mix and cover the shutoff bedrock fracture with the basement rock sillar, blocking-up water contacts with shale layer.
For achieving the above object, the technical solution adopted in the utility model provides the composite foundation that a kind of port works riprap foundation mixes with non-dispersible underwater concrete, this composite foundation is attached on the mud stone ground, wherein: adhere to the non-dispersible underwater concrete layer on the top layer of described mud stone ground, riprap foundation is positioned on the non-dispersible underwater concrete layer, riprap foundation bottom piece stone embeds and forms the mixture layer in the non-dispersible underwater concrete layer, and described riprap foundation and mixture layer form composite foundation.
The beneficial effects of the utility model are that this composite foundation is except the requirement of satisfying general basis, the more important thing is that this composite foundation can closely mix and cover the shutoff bedrock fracture with the basement rock sillar, blocking-up water contacts with shale layer, avoided mud stone under the water long term, to produce softening and argillization phenomenon, and the adverse effect to harbour gravity structure stability and foundation capability of bringing thus.

The specific embodiment
Below in conjunction with accompanying drawing and case history the composite base structure that port works riprap foundation of the present utility model mixes with non-dispersible underwater concrete is described further.
The composite foundation that port works riprap foundation of the present utility model mixes with non-dispersible underwater concrete, this composite foundation is attached on the mud stone ground, the non-dispersible underwater concrete layer is adhered on top layer at the described ground of mud stone under water 2, riprap foundation 3 is positioned on the non-dispersible underwater concrete layer, thereby forms the mixture layer 1 that the non-dispersible underwater concrete layer mixes with riprap foundation 3 bottom piece stones.
The thickness of described non-dispersible underwater concrete layer is 1000mm～2000mm.
The composite foundation that port works riprap foundation of the present utility model mixes with non-dispersible underwater concrete is achieved in that
Utilize dredge boat or cooperate underwater demolition, excavate overlying soil to satisfactory mud stone ground 2, after removing mud stone ground 2 surperficial residues with water under high pressure under diver's the guiding, adopt again and build approximately the thick non-dispersible underwater concrete of 1000mm～2000mm such as vertical tube method or additive method and be covered under water on the mud stone ground 2, utilize the Self-leveling characteristic of non-dispersible underwater concrete closely to mix with the basement rock sillar of mud stone ground 2, and covering shutoff bedrock fracture, concrete capable of not dispersing solidifies front throwing riprap foundation 3 under water, the bedding piece stone of riprap foundation 3 embeds in the non-dispersible underwater concrete, thereby formed bedding piece stone and non-dispersible underwater concrete mixture layer 1 by riprap foundation 3, formed composite foundation by riprap foundation 3 and mixture layer 1.
Claims (2)
1. composite foundation that the port works riprap foundation mixes with non-dispersible underwater concrete, this composite foundation is positioned under water on the mud stone ground, it is characterized in that: the non-dispersible underwater concrete layer is adhered on the top layer at the described ground of mud stone under water (2), riprap foundation (3) is positioned on the non-dispersible underwater concrete layer, the bottom piece stone of riprap foundation (3) embeds and forms mixture layer (1) in the non-dispersible underwater concrete layer, and described riprap foundation (3) forms composite foundation with mixture layer (1).
2. the composite foundation that mixes with non-dispersible underwater concrete of port works riprap foundation according to claim 1, it is characterized in that: the thickness of described non-dispersible underwater concrete layer is 1000mm～2000mm.
