Description
Technical field
The utility model relates to the barricade in a kind of subgrade construction, is specifically related to a kind of reinforced earth bulkhead.
Background technology
Retaining wall is retaining structure form common in all kinds of engineering construction, it have structure simple, take up an area less, easy construction and the plurality of advantages such as cheap.Be widely used in highway, railway, urban construction, be applied to the fields such as dam construction, riverbed regulation, port works, water and soil conservation, the reallocation of land, landslide control simultaneously.
Reinforced earth is a kind of composite earth adding lacing wire in soil.In soil, add lacing wire can improve intensity in the soil body, increase the stability of the soil body.At present, the banded lacing wire of main employing geosynthetics is main, mainly polypropylene geotextile strips, steel plastic compount Soil test, they are for increasing the slow soft plastic body of resistance, and in the soil body, rib tape mainly bears the pulling force of the soil body and external load effect generation, under dynamic loading, rib tape increases resistance velocity lag, and resistance can not be provided in time to resist the destruction of dynamic load to the soil body.In many cases, it is not insufficient strength own that lacing wire was lost efficacy, but increasing resistance speed is accelerated not as good as the increment of load of dynamic load, the soil body destroys because short time set transfinites, thus cause body of wall embankment unstability, on the other hand, owing to being subject to non-uniformity of soil, the factors such as construction and external environment, the unstable failure generation slide surface place pulling force of body of wall is larger, traditional rib tape can be pulled off, or the phenomenon be pulled out because drawing rib length is not enough, indivedual muscle material may be pulled out because of not enough with surrounding soil interface friction force, cause the panel mobile dislocation before wall held by muscle material, destroying appears in retaining wall local, now, lacing wire in reinforced earth can be lost efficacy, tensile strength reduces, threaten body of wall and other engineering safeties.Muscle material length ensures one of key factor of not being pulled out, in order to save muscle material, should shorten muscle material length under the prerequisite ensureing stability as far as possible.
Utility model content
The utility model is that the banded lacing wire tensile strength for solving existing reinforced earth bulkhead is low, the easy unstability of body of wall embankment, the problem of Stability for Retaining Wall Structure difference, and then provides a kind of novel reinforced earth bulkhead.
The utility model is the technical scheme taked that solves the problem: a kind of novel reinforced earth bulkhead comprises shingle nail and multiple lacing wire, described shingle nail is prefabricated component, it also comprises pull bar, multiple ribbed belt, multiple L shape muscle nail and at least two muscle groups, multiple lacing wire is reinforcing bar, one end connection wall panel of lacing wire, the other end cylinder lever connecting rod of lacing wire, L shape muscle nail is arranged on pull bar, the galianconism of L shape muscle nail is connected with pull bar, lacing wire is fixed with at least two muscle groups along the length direction of lacing wire, each muscle group is made up of two muscle, lacing wire and a muscle are wound with ribbed belt respectively, angle between lacing wire and a muscle is 35 ° ~ 40 °, propping up muscle is rectangle rib tape, the external surface of lacing wire and a muscle all scribbles antirust coat.
The beneficial effects of the utility model are: lacing wire of the present utility model and an angled layout of muscle form the dendritic muscle material of root, the anchorage length of lacing wire can be reduced, good integrity, can foundation deformation be adapted to, increase soil body stability, antiseismic, meanwhile, be provided with pull bar and L shape muscle nail, L shape muscle nail is inserted in soil layer, increase the retaining wall muscle material stability of reinforcement, ensure that pulling test strength, body of wall earth fill not easily unstability.
Reinforced earth is commonly used for a gear building in civil engineering engineering, sometimes also for consolidated subsoil.Reinforced soil retaining wall is divided into some subareas by imbedding lacing wire the soil body, by rubbing action, the lateral earth pressure of each subarea soil is passed to lacing wire, and the stressed of dendritic muscle material is born together with a muscle group structure by lacing wire, improves each subarea holistic resistant behavior.Banketing and under external load effect, contacting more fully with closely knit banketing, muscle material, pull bar and L shape muscle are followed closely and soil particle interacts improves native physical and mechanical property, soil body shear resistance is improved greatly, prevent the soil body from producing slip, so stabilize the soil body, retaining wall structure is stability more.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the lateral view of pull bar and L shape muscle nail in Fig. 1, and Fig. 3 is another kind of structural representation of the present utility model.
Detailed description of the invention
