Abstract
The present invention relates to a ribbed retaining wall which belongs to the geotechnical engineering and building technical field. The present invention is mainly characterized in that a face wall is formed by that a plurality of layers of modules are orderly and uniformly retreated layer by layer, are horizontally placed, and are stacked dryly, the inner side of the face wall are provided with two filtering bodies and are provided with transverse water permeable pipes. The present invention has the advantages of reasonable structure, low manufacturing cost, convenient construction and good adaptability for foundations; the shock resistance is better than that of a gravity-type structure, and the present invention is suitable for various dock walls, embankments, bridgeheads and quay wing walls.
Description
Technical field
The invention belongs to geotechnical engineering and technical field of buildings, relate to a kind of reinforced soil retaining wall.
Prior art is introduced
The ordinary construction of retaining structure is a retaining wall, and its effect is a retaining soil.Gravity retaining wall relies on the weight of body of wall self to come earth lateral pressure behind the balance wall, and materials for wall is that piece stone is built with masonry of cement mortar or steel concrete and formed.This structure is widely used in various revetments, embankment, end of the bridge and harbour aileron.Cemented rock retaining wall or steel bar concrete barricade volume are big, and it is many to consume material.When body of wall is tall and big, because from great, to ground requirement for bearing capacity height.This structure bricklaying quantity is many, cost is high.Special more uneconomical in the area that stone material lacks.People are in order to make the retaining wall economical rationality, to reduce cost, and manage to utilize to banket behind the face wall to add an amount of stretching resistance material in the material, improve the shear behavior of soil, reach to form the purpose that the whole soil body keeps off soil, promptly so-called reinforced soil retaining wall.Reinforced soil retaining wall has strip-type reinforced soil retaining wall or geotextiles packaging type retaining wall according to the reinforcement material difference at present, and metope is the concrete solid slab, facts have proved the retaining soil effect of reinforced soil retaining wall.But because of this class wall construction is difficult for grasping, distortion is big.
Summary of the invention
The object of the invention provides easy construction, safe, reliable, economic, practical a kind of reinforced soil retaining wall.
The objective of the invention is to be achieved through the following technical solutions: a kind of reinforced soil retaining wall, comprise face wall, the basis of face wall bottom, the soil body that wraps up with geotextiles around each layer geo-grid of face wall inboard and the geo-grid, it is characterized in that face wall is made of every layer of module drystone that evenly moves back layer horizontal positioned successively on the basis, in the hole of latch insert module, connect between the module up and down, geo-grid end behind the face wall stretches in the groove between the levels module, rubble filter body is set between the soil body that face wall is inboard and geotextiles is wrapped up, the end of the soil body is provided with the medium coarse sand filter body of isolating with geotextiles, under the face wall basis, geotextiles and hardcore bed basis are arranged under the bottom soil body, be provided with some horizontal in filter body behind the following face wall of waterline and the solum, vertical water-permeable pipe; The module front end face is concavo-convex cambered surface, rear end face is the plane, vertical cavity is arranged on the module body between the front/rear end, two sides are symmetrical concavity face, there is a protruding key at the nearly middle part of both sides of the chest wall one side that forms between cavity and the concavity face, between protruding key and the concavo-convex cambered surface end hole is arranged, there is a groove at the nearly middle part of both sides of the chest wall another side, between groove and the concavo-convex cambered surface end hole is arranged; The protruding key of both sides of the chest wall one side and the groove and the hole of hole and another side equidistantly misplace in the module, the groove fit of isometrical, the protruding key of the hole in the module and another module, the groove of one side and the distance of hole and rear end face are greater than the distance of the protruding key of another side and hole and rear end face.
The present invention is rational in infrastructure, novel, economically save, cheap, make full use of soil resource, save 30-50% than traditional retaining wall.Reliable in quality, module and the material of putting more energy into are factory normalization production, and high molecular polymer is put more energy into material life-span more than 50 years in the soil body.This structure is good to ground compliance, is adapted at soft foundation and builds, and particularly anti-seismic performance is better than gravity structure.Easy construction, be conventional construction technology, easy to operate, speed is fast.Good looking appearance, simple and unsophisticated generous, have natural stone walling sensation, go back to nature.
