Abstract
The utility model discloses a kind of Anti-settling device of highway subgrade, comprise the supercrust, grains of sand processing layer and the base course that set gradually from top to bottom; Some layers of geogrids layer are arranged at intervals with in described base course; Described geogrids layer is provided with 3-5 layer; Described base course bottom part is furnished with some raised lines; The utility model adopts grains of sand processing layer to combine with geogrids layer, and grains of sand processing layer can effectively prevent surface gathered water from penetrating into base course, and geogrids layer can improve bearing capacity of foundation soil rapidly, the development of control settlement amount; Simultaneously by the setting of raised line, and raised line is set to inverted trapezoidal shape or arc-shaped, make raised line by the load from base course on wider subbase, thus can effectively can prevent the generation of subgrade settlement phenomenon, improve travel safety, extend Road Service Life.
Description
Technical field
The utility model is specifically related to a kind of Anti-settling device of highway subgrade, belongs to highway construction technical field.
Background technology
Subgrade settlement is the common a kind of phenomenon endangering traffic safety of highway use procedure, and owing to bearing higher load effect for a long time, cause roadbed integral sinking, formation is uneven, and when vehicle travels on this up-and-down road surface, being that driving is big really avoids.And existing anti-settling facility is only lay one deck processing layer between the basic unit and roadbed stake of roadbed, too simple structural measure is difficult to the problem thoroughly solving roadbed subsidence, especially at the road that the location that geological conditions is poor is built, anti-settling measure is carried out particularly important.
Summary of the invention
For the problems referred to above, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, practical, effectively can prevent roadbed subsidence, is conducive to the Anti-settling device of highway subgrade improving highway application life and travel safety simultaneously.
Anti-settling device of highway subgrade of the present utility model, comprises the supercrust, grains of sand processing layer and the base course that set gradually from top to bottom; Some layers of geogrids layer are arranged at intervals with in described base course; Described geogrids layer is provided with 3-5 layer; Described base course bottom part is furnished with some raised lines.
Further, described raised line is inverted trapezoidal shape raised line.
Further, described raised line is circular arc raised line.
The utility model beneficial effect: a kind of structure of the present utility model is simple, practical, effectively can prevent roadbed subsidence, is conducive to the Anti-settling device of highway subgrade improving highway application life and travel safety simultaneously; The utility model adopts grains of sand processing layer to combine with geogrids layer, and grains of sand processing layer can effectively prevent surface gathered water from penetrating into base course, and geogrids layer can improve bearing capacity of foundation soil rapidly, the development of control settlement amount; Simultaneously by the setting of raised line, and raised line is set to inverted trapezoidal shape or arc-shaped, make raised line by the load from base course on wider subbase, thus can effectively can prevent the generation of subgrade settlement phenomenon, improve travel safety, extend Road Service Life.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
Anti-settling device of highway subgrade as shown in Figure 1, comprises the supercrust 1, grains of sand processing layer 2 and the base course 3 that set gradually from top to bottom; Some layers of geogrids layer 4 are arranged at intervals with in described base course 3; Described geogrids layer 4 is provided with 3-5 layer; Described base course 3 bottom part is furnished with some raised lines 5; Described raised line 5 is inverted trapezoidal shape raised line; Described raised line 5 is circular arc raised line.
The utility model adopts grains of sand processing layer to combine with geogrids layer, and grains of sand processing layer can effectively prevent surface gathered water from penetrating into base course, and geogrids layer can improve bearing capacity of foundation soil rapidly, the development of control settlement amount; Simultaneously by the setting of raised line, and raised line is set to inverted trapezoidal shape or arc-shaped, make raised line by the load from base course on wider subbase, thus can effectively can prevent the generation of subgrade settlement phenomenon, improve travel safety, extend Road Service Life.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
