Abstract
The utility model discloses a kind of novel Semi-rigid Road Base Course, comprise basic unit's main body, the both sides of basic unit's main body are provided with strip slip casting band, the graded broken stone matrix of compacting is covered with in the inner side of strip slip casting band, in graded broken stone matrix, be provided with some column injecting cement pastes simultaneously, column injecting cement paste can improve road base structural strength, prevent the base course surface through crack because the reasons such as semi-rigid material drying shrinkage, temperature contracting cause, the strip slip casting band that this base layer structure side is arranged can prevent sub-surface from occurring subsiding, and improves resistance to overturning.
Description
Technical field
The utility model relates to road construction technical field, is specifically related to a kind of novel Semi-rigid Road Base Course.
Background technology
Semi-rigid type base is mainly used in highway engineering, refer to plate body can be formed and there is the basic unit of certain flexural strength with inorganic colloid methoder making, because the present semi-rigid type base such as drying shrinkage, temperature contracting of material easily ftractures, crack can reflex to road surface, causes pavement cracking.
Utility model content
(1) technical problem that will solve
In order to overcome prior art deficiency, now proposing a kind of structure improvement, greatly can reduce the novel Semi-rigid Road Base Course of one of pavement cracking situation simultaneously.
(2) technical scheme
Of the present utility modelly to be achieved through the following technical solutions: the utility model proposes a kind of novel Semi-rigid Road Base Course, comprise basic unit's main body, described basic unit main body is made up of in conjunction with slip casting the graded broken stone matrix of compacting, in the both sides slip casting of graded broken stone matrix, form the slip casting band parallel with road, some column injecting cement pastes are set in both sides slip casting band mid portion graded broken stone matrix simultaneously.
Improve as one, described both sides slip casting bandwidth is greater than basic unit's body thickness.
As further improvement, described any three adjacent column injecting cement pastes are equilateral triangle arrangement.
(3) beneficial effect
The utility model, relative to prior art, has following beneficial effect:
The novel Semi-rigid Road Base Course of the one that the utility model proposes, local slip casting is carried out in the graded broken stone matrix of compacting, add basic unit's body interior rigidity, basic unit's main body is avoided to produce the crack run through, then road surface is destroyed, the both sides of basic unit's main body are cast with strip slip casting band, and it can well limit basic unit's main body and occur locally to topple over, and can ensure the integrality of basic unit's main body better.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross section structure schematic diagram.
1-strip slip casting band; 2-graded broken stone matrix; 3-column injecting cement paste.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The novel Semi-rigid Road Base Course of one as depicted in figs. 1 and 2, comprise basic unit's main body, it is characterized in that: the both sides of described basic unit main body are provided with strip slip casting band 1, be covered with the graded broken stone matrix 2 of compacting in the inner side of described strip slip casting band 1, in described graded broken stone matrix 2, be provided with some column injecting cement pastes 3 simultaneously.
Wherein, described strip slip casting band 1 width is greater than basic unit's body thickness; The arrangement in equilateral triangle of described any three adjacent column injecting cement pastes 3.
The novel semi-rigid road base of one that above specific embodiment is mentioned, it in the specific implementation, according to industrial grade and the traffic loading situation of road, determine the thickness of road foundation width and basic unit, first making graded broken stone matrix 2, after utilizing compacting machinary to roll, in graded broken stone matrix 2 both sides slip casting, form strip slip casting band 1, then in graded broken stone matrix, some column injecting cement pastes 3 are evenly cast with, any three adjacent column injecting cement pastes 3 are in equilateral triangle, its objective is to ensure that column injecting cement paste 3 is uniformly distributed in graded broken stone matrix 2, structural expression is better, it is stability in order to ensure strip slip casting band 1 that strip slip casting band 1 width is greater than basic unit's body thickness, to support whole basic unit main body better to prevent from subsiding.
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.
Claims (3)
1. a novel Semi-rigid Road Base Course, comprise basic unit's main body, it is characterized in that: the both sides of described basic unit main body are provided with strip slip casting band (1), be covered with the graded broken stone matrix (2) of compacting in the inner side of described strip slip casting band (1), in described graded broken stone matrix (2), be provided with some column injecting cement pastes (3) simultaneously.
