Detailed description of the invention
The specific embodiment of the present invention is introduced in detail below in conjunction with accompanying drawing.
In embodiments, for sphere interlocking cement concrete brick, load-carrying members layer is described.
Fig. 1 is sphere interlocking cement concrete brick plan view, as shown in the figure, sphere interlocking cement concrete brick 10 is made up of the brick plate 1 of geo-grid 2 with each lattice room being arranged in geo-grid 2, formed after cement concrete continuous pouring is solidified by brick plate 1 in geo-grid 1, the thickness of brick plate 1 is identical with the thickness of geo-grid 2.The shape of brick plate 1 is square, and as shown in Figure 3, be formed with protuberance 1a in two sides of brick plate 1, another two sides are formed with recess 1b.Protuberance 1a is passed through together with the mutual interlocking of recess 1b between adjacent brick plate 1.As shown in Figure 2, have the shape same with the billiard table T-phase separated from spheroid Q, its surface is respectively spheric M to protuberance 1a and recess 1b.In the lattice room of geo-grid 2, two sidewalls are formed with inside male and fomale(M&F) 2a, another two sidewalls are formed with outside male and fomale(M&F) 2a, and protuberance 1a and recess 1b is shaping by male and fomale(M&F) 2a.That is, naturally shaping together with in brick plate 1 and protuberance 1a and the recess 1b lattice room in geo-grid 1.
Protuberance 1a and recess 1b is arranged on the centre position of the width of brick plate 1 side, the centre of thickness direction or position on the lower side (with reference to Fig. 4).
The area of brick plate 1 is 0.4m
2below, thickness is 0.1m ~ 0.4m, and ratio 1≤a≤4 of area and thickness, preferred area is at 0.36m
2and below, thickness of slab is between 0.1m ~ 0.3m.
The sidewall thickness of the lattice room between brick plate 1 is below 2mm, preferred below 1mm.
Sphere interlocking cement concrete brick 10 is arranged on the top of roadbase B as shown in Figure 4.During construction, go forward first to lay geo-grid 2 at roadbase B, then by compression pump, the cement concrete pulp spraying mixed and stirred is poured into cellular lattice indoor and form.Owing to four sidewalls of lattice room being formed with respectively the male and fomale(M&F) of spheric, by being positioned at the recess 1b of male and fomale(M&F) 2a together with the mutual interlocking of protuberance 1a between adjacent tile panel 1, the pavement crack that the cement board that effectively prevent monobloc cast causes because road surface vertical and horizontal effect of stress is uneven, even ruptures.The road surface of such formation can directly use, and also as required, as shown in Figure 6, can be attached with the surface course 3 of pitch on the surface of sphere interlocking cement concrete brick 10, improves comfortableness during driving.
As from the foregoing, owing to passing through the recess 1b of spheric between adjacent tile panel 1 together with the mutual interlocking of protuberance 1a, not only ensure that the globality of sphere interlocking cement concrete brick 10, also substantially reduce face thickness rate, make stress unit become close to block structure from a simple beam, prevent generation or the fracture of crackle.
Due to recess 1b and protuberance 1a that the interlocking mechanism between brick plate 1 is spheric, the transmission of the power between brick plate 1 is more prone to, and the stress of vertical direction can be disperseed to horizontal direction better.Further, as shown in Figure 5, at automobile C through out-of-date, when brick plate 1 is subject to the effect of external force F, between brick plate 1 and brick plate 1, up-narrow and down-wide wedging method can be produced, be conducive to ground row waterborne.Therefore, this road surface (road surface structare layer) structure is specially adapted to the large roadbed of substrate water content that coarse aggregate material fills, especially inherently fills out the road surfacing on lake, sea-filling basement.
Be formed in the centre position of the width of brick plate 1 side due to recess 1b and protuberance 1a, the centre of thickness direction or position on the lower side, the mechanical structure therefore between brick plate 1 and brick plate 1 is also more reasonable.
Due to the area to brick plate, thickness, face thickness rate limits, and the stress of brick plate 1 own can be prevented uneven and crack or rupture.
Shape due to brick plate is rectangle, and the lattice chamber shape of geo-grid is set to rectangle, reduces manufacturing cost.
Because the thickness of the sidewall of lattice room is 1 or below 2mm, the manufacturing cost of geo-grid not only can be reduced, also can by the distance controlling between brick plate 1 and brick plate 1 in less scope.
Geo-grid 2 adopts engineering plastics to make by the mode such as injection moulding or welding.Below the geo-grid that welding manner makes is described.
This geo-grid is formed by connecting at each Nodes by multiple sheet material, and being formed between sheet material and sheet material with node is the latticed lattice room of tie point, and sidewall is formed with male and fomale(M&F), male and fomale(M&F) by the lattice room of side to the indoor protrusion of adjacent opposite side lattice.
Its manufacturing step is as follows:
Step 1-presses the male and fomale(M&F) of certain gap-forming spheric on the sheet material of strip,
Step 2-is overlapping by sheet material, and makes the male and fomale(M&F) on each sheet material together nestable respectively,
The Nodes of step 3-between each male and fomale(M&F), will weld alternately between two before and after adjacent sheet material or bond together.
Such geo-grid, when not using, together with sheet material overlaps each other with sheet material, be convenient to store and transport, during use, at two ends, geo-grid is pulled open, the lattice room of square or rhombus can be formed between sheet material, after being fixed geo-grid, cement concrete slurry of can spraying makes sphere interlocking cement concrete brick.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.Shape as brick plate may also be rectangle, hexagon and other shapes except square, as long as form interlocking structure between brick plate.Interlocking structure between brick plate also and not necessarily be sphere, can also be other shapes, as triangle etc.The material of geo-grid also can adopt the other materials such as rubber, as long as have certain intensity except employing engineering plastics.The purposes of load-carrying members layer is also not limited to road surface, also can be used for the surface course of harbour, factory position warehouse, mining area ground layer, any bearing courses for the purpose of load-bearing such as the surface course of panel enrockment dam.When for road surface, can be used for surface layer and the internal layer of the original common or speedway of newly-built or overhaul.
