(2) background technology
The explosion-proof dike object of construction production adopts stone-laying or concrete scheme all the time.This way can not play the impact energy problem that abundant absorption blast that explosion-proof dike should rise is produced.When blast produces because engineering is a rigid structures, destroyed after, can produce and break and splash formation secondary destruction.Inner use stone-laying or concrete construction in the post simultaneously not only can not afforest but also make target obvious, thereby destroys environment.Traditional method also is subjected to height restriction, and majority can only be done the explosion-proof dike about 5 meters; The steel concrete explosion-proof dike can accomplish more than ten meters, but involves great expense, long construction period, and target is obvious.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, but the greening and environmental protection of a kind of height height, the flexible explosion-proof dike that cost is low are provided.
The utility model is achieved by the following technical solution:
A kind of flexible explosion-proof dike comprises ground and explosion-proof levee body, and its special character is: described explosion-proof levee body adopts geogrids layer and packing layer to replace pressing and forms.
Flexible explosion-proof dike of the present utility model, it further improves and is: described geogrids layer adopts unidirectional geo-grid, and the unidirectional geo-grid employing of following one deck pitman is strained with last layer and is connected.Describedly adopt pitmans to carry out to drawing connection with two relative unidirectional geo-grid of one deck.The metope of described explosion-proof levee body is enclosed with planting soil filler bag or turf.
Flexible explosion-proof dike of the present utility model, described explosion-proof levee body top is equipped with the two-way geo-grid of one deck, has built concrete in the two-way geo-grid.Or: described explosion-proof levee body top kind is implanted with turf.
Described ground comprise the permeable bed course of the rubble of lowermost end with and on two-layer two-way geo-grid, be filled with filler in the two-way geo-grid.
Flexible explosion-proof dike of the present utility model, the material of described unidirectional geo-grid and pitman is a high density polyethylene (HDPE), and the material of two-way geo-grid is a polypropylene, and filler is soil or rock ballast; The grid carbon black content is no less than 2%, and particle is uniformly dispersed lustrous surface.
The job practices of flexible explosion-proof dike of the present utility model comprises the steps: (1) laying ground; (2) bottom is completely spread unidirectional grid, metope parcel planting soil, and the outside is laid turf and is carried out the body of wall greening, and every bed thickness is 50 centimetres behind the filling compaction; Adopt that mechanical ramming is no less than three times more than 20 tons, adopt hand compaction in 1.5 meters of the metopes; (3) unidirectional grid begins interlayer from the second layer and adopts pitman to be connected with last layer and strain, and unidirectional grid employing pitman carries out drawing connection between explosion-proof dike two relative metopes, wraps up planting soil, laying turf, filling compaction again, until absolute altitude; (4) compacting after the last unidirectional geo-grid anti-package of one deck.
Flexible explosion-proof dike of the present utility model adopts geo-grid reinforcement flexible structure, has prolonged the action time that explosive impacts explosion-proof dike, thereby has solved the absorption problem of the indeterminable impact energy of traditional explosion-proof dike at one stroke.Can not produce simultaneously secondary in blast process destroys.With traditional explosion-proof dike (concrete and stone-laying) but compare also have highly high greening and environmental protection, cost low (with 12 meters high and greening explosion-proof dike is example: flexible explosion-proof dike is compared traditional explosion-proof dike and saved cost about 45%), speed of application is fast and ground is had the advantage of adaptive capacity preferably.Reinforced earth explosion-proof dike engineering belongs to new technology, new technology, modern design, attractive in appearance, take up an area of fewly, protect farmland, reduce destruction to surrounding enviroment, belong to environment-friendly engineering.The impact energy that this type of engineering can really absorb blast and produced has been started the beginning that national defence explosion-proof dike engineering is used the flexible structure scheme, makes explosion-proof dike class engineering step a significant step on the basis of traditional construction scheme.
