Technical Field
The utility model relates to a steady layer construction technical field of water especially relates to a steady layer structure of water that can restrain bituminous paving deformation.
Background
The asphalt pavement is usually long in longitudinal length along the running direction of a vehicle and relatively narrow in transverse width, so that loads are mainly concentrated in the longitudinal direction of the asphalt pavement, and the water-stable layer is a cement-stable gravel layer, namely cement-solidified graded gravel is adopted, and the maintenance is completed through compaction.
The water-stable layer is generally laid under the road surface, and the water-stable layer has the function of bearing, and is a main bearing structure layer, particularly in the asphalt road surface. And secondly, the water stability is improved, the underground water is prevented from rising and the surface water is prevented from seeping, because the broken stone and the cement are bonded together through the cementing material, when the stress is too concentrated, the local deformation is easy to occur, and further the asphalt pavement above the broken stone is deformed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a water stabilization layer structure that can restrain bituminous paving deformation is provided to above-mentioned technical current situation.
In order to achieve the above purpose, the utility model provides a following technical scheme:
a water stabilization layer structure capable of inhibiting deformation of an asphalt pavement comprises a roadbed and the asphalt pavement, wherein a water stabilization layer is arranged between the bottom surface of the asphalt pavement and the top surface of the roadbed, the water stabilization layer is formed by compacting cement-bonded graded broken stones, the water stabilization layer comprises a body which is compacted into a block shape, a transverse steel bar is inserted into the body, the middle part of the transverse steel bar is upwards bulged to form an upwards bent part, the two ends of the transverse steel bar are downwards sunken to form downwards bent parts, a plurality of first trapezoidal grooves are formed in the two transverse sides of the body, the end parts of the two ends of the transverse steel bar extend into the first trapezoidal grooves, a longitudinal steel bar is further inserted into the body, the longitudinal steel bar longitudinally penetrates through the body, a plurality of second trapezoidal grooves are formed in the two longitudinal sides of the body, and the two ends of the longitudinal steel bar extend into the second trapezoidal grooves, the height of the longitudinal steel bar is consistent with the height of the bottommost part of the upper bent part and the height of the topmost part of the lower bent part.
As an improvement of the utility model, the ends of the transverse steel bars and the longitudinal steel bars are all formed with anchors.
As the utility model discloses a preferred, the water stabilization layer is with the rubble as the aggregate to fill slag and gelled material in the space of aggregate, contain cement among the gelled material, form the aggregate paving compaction through the compactor afterwards the water stabilization layer.
Compared with the prior art, the utility model has the advantages of: through bury many longitudinal reinforcement and horizontal reinforcing bar in advance in the water stabilization layer body for they can interact, promote the horizontal and fore-and-aft intensity of water stabilization layer, can show the bearing capacity who improves the road surface under the condition that does not increase prestressing force gusset, and this kind of stiffened plate can show reduction maintenance cost simultaneously.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in the accompanying drawings, the embodiment is a water stabilization layer structure capable of inhibiting deformation of an asphalt pavement, which comprises a roadbed 1 and an asphalt pavement 2, wherein a water stabilization layer 3 is arranged between the bottom surface of the asphalt pavement and the top surface of the roadbed, the water stabilization layer uses gravels as aggregates, gaps of the aggregates are filled with slag and cementing materials, the cementing materials contain cement, then the aggregates are paved and compacted through a compactor to form the water stabilization layer, the water stabilization layer comprises a block-shaped body which is compacted, transverse steel bars 4 are inserted into the body, the middle parts of the transverse steel bars are upwards bulged to form upwards bent parts 41, two ends of the transverse steel bars are downwards sunken to form downwards bent parts 42, a plurality of first trapezoidal grooves 5 are formed on two transverse sides of the body, the end parts of the two ends of the transverse steel bars extend into the first trapezoidal grooves, longitudinal steel bars 6 are inserted into the body, the longitudinal steel bar is longitudinally penetrated through the body, the longitudinal steel bar is in a straight-line rod shape, a plurality of second trapezoidal grooves 7 are formed in the two longitudinal sides of the body, the first trapezoidal grooves are arranged at the transverse equal intervals of the body and are located at the same height, and the second trapezoidal grooves are arranged at the longitudinal equal intervals of the body and are also located at the same height.
In order to prevent the transverse steel bars and the longitudinal steel bars from moving in the horizontal direction after being buried, the ends of the transverse steel bars and the ends of the longitudinal steel bars are respectively provided with an anchor 8, the diameter of the anchor is larger than that of the transverse steel bars and the longitudinal steel bars, and the anchor is in a barb shape, so that the anchor can firmly grasp the bottoms of the first trapezoidal grooves and the second trapezoidal grooves, and the transverse steel bars and the longitudinal steel bars can be firmly fixed in the water stabilization layer body. In addition, due to the formation of the anchoring, the sections of the two end parts of the plate screen, where the longitudinal steel bars are difficult to arrange, are enlarged, so that the damage of the two end parts of the longitudinal steel bars can be effectively controlled under the condition of ensuring the economy and convenience in the design and construction stages.
The two ends of the longitudinal steel bar extend into the second trapezoidal groove, and the height of the longitudinal steel bar is consistent with the bottommost height of the upper bent part and the topmost height of the lower bent part, so that the longitudinal steel bar is positioned at the wave-shaped trough position of the transverse steel bar when viewed from the cross section. The water stabilization layer structure of the embodiment is characterized in that a plurality of longitudinal steel bars and transverse steel bars are embedded in the water stabilization layer body in advance, so that the longitudinal steel bars and the transverse steel bars can interact with each other, the transverse strength and the longitudinal strength of the water stabilization layer are improved, the bearing capacity of a road surface can be obviously improved under the condition that prestressed rib plates are not increased, and meanwhile, the reinforcing plate can obviously reduce the maintenance and management cost.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
