Background technique
Retaining wall is a kind of common retaining structure form, and water conservancy and hydropower, traffic, the room field Jian Deng is widely applied.At present Retaining wall is generally used cemented rock, cast-in-situ steel reinforced concrete or precast construction.But due to the reduction of lithotome, slurry Building block stone retaining wall application is restricted, and the cast-in-situ concrete construction period is long, needs a large amount of template, and concrete pours Build the influence constructed vulnerable to temperature and weather.Prefabricated barrier wall structure, it is easy to make since structure type is simple, detachably, it is convenient for The features such as rapid construction, is gradually widely applied in engineering.
There are mainly two types of forms for the prefabricated barrier wall structure that engineering uses at present, the first is built using building block layer layer heap, such as From embedded retaining wall, building block is mostly plain concrete or light-concrete structure;Second of use is prefabricated assembled, by the knot of retaining wall Structure feature splits into the prefabricated components such as bottom plate and vertical plate, reserves notch between component and connect with reinforcing bar, hung by scene Dress, later period pour into concrete second pouring and form overall structure.
Have the characteristics that good water permeability, from heavy and light from embedded retaining wall, but needing from the embedded retaining wall to rely on more geotextiles or The soil body after the reinforcement walls such as TGXG, working procedure is also relative complex, is suitable for the water surface or more more and constructs;Earth-retaining height is more than one After determining range, the deformation of wall is increased, and can cause to misplace from patch, or even cause to destroy;Assembled retaining wall component interconnecting piece Divide and generally require second pouring, needs separately to found segment template;In order to facilitate construction, second pouring amount, structure are reduced in equal length The size of part again should not be too small, and the lifting that this will lead to component is inconvenient.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of prefabricated barricade, structure type is simple, production side Just, detachably;By notch build-in between component, second pouring is avoided, is convenient for rapid construction;It is applicable in scene and temporarily sets up heap , it has been also applied for rapid construction in the case where water.
To achieve the above object, the utility model provides the following technical solutions: a kind of prefabricated barricade, including several main body branch Support component, baffle and concrete foundation component;Body supports component two sides are equipped with notch, and build-in is distinguished in the baffle two sides In the notch of body supports component, the body supports component is fixed in concrete foundation component.
Preferably, body supports component is prefabricated reinforced concrete component.
Preferably, body supports component is L-type body supports component, counterfort type body supports component or sheet pile type main body branch Support component.
Preferably, the baffle uses one group of cylindrical member to be mounted in notch to form continuous earth-retaining face.
Preferably, the cylindrical member is prefabricated reinforced concrete component.
Preferably, body supports component is mounted in concrete foundation component to form overall structure.
Preferably, concrete foundation member bottom section is additionally provided with bed course.
Preferably, body supports component top, which is additionally provided with, bears down on one.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model is different from other assembled barrier wall structures, and wall body structure is simplified into main body supporting structure and gear Plate part simplifies the quantity of component, passes through notch build-in between component, do not need the casting of later period formwork erection;Baffle part uses The problems such as cylindrical prefabricated parts are formed along notch build-in, and component is light and handy, are easy to lift, and not consider component placement direction;Circle Cylindricality prefabricated components molding tool is simple, is convenient for relatively mass production, and transport and storage are also more convenient;Wall part has Water penetration is conducive to the circulation of water body after wall front wall, advantageous to the safety and stability of structure, also complies with wanting for Ecological waterscape design It asks;Concrete foundation component also serves as bottom plate, overall structure coaction is formed with each body supports component, suitable for there is the feelings of water It constructs under condition.
