Abstract

The invention relates to a building and road basic cushion for manufacturing a prefabricated block by taking cement concrete as a base material. The cushion is characterized in that geometrical blocks A and B are arranged; by virtue of the characteristic of high rigidity of a concrete material, the two geometrical blocks A and B are engraved into a sheet and are overlaid layer by layer, so that an upper load is quickly transferred to base oil; the diffusion angle of a common cushion is generally about 30 degrees, and the difference of the diffusion angle with the blocks A and B is 49.86-30=19.86, so that the effect is remarkable; the cushion is applied to a road project, so that the road is convenient and reliable to maintain.

Description

The prefabricated AB blocks bed course of cement concrete

Technical field

The blinding layer of road and building.

Background technology

Between transition zone and pavement of road basic unit and soil matrix between the structural substrates and foundation soil of house foundation structure Transition zone etc. building basis and soil between transition zone, main effect be will superstructure load spread under pass, The stress intensity made to soil is less than permissible value；The transition zone appellation of this effect is relatively more, and here system is referred to as " bed course "； Effect of the bed course on mechanics is that load " is diminished " by " angle of flare ", and the carrying that load is reduced to foundation soil is allowed power model In enclosing, foundation soil is reached；At present, using cement, sand, gravel, slag, rendzinas etc. more than bed course, angle of flare is smaller, does not have Give full play to the mechanics feature of material itself；Bed course is thick, increased construction costs.

The content of the invention

In order to play material mechanics feature itself, reduce cushion thickness and again superstructure load is reached basis by permissible value Soil, the technical solution used in the present invention is：

1st, using the prefabricated bulk strength of cement concrete, rigidity characteris, bis- kinds of geometry blocks of A and B are designed, B blocks carve conjunction on A blocks, It is fastened to each other in blocks；Then layer by layer dislocation is stacked, and interlayer sanding rapidly diminishes upper load stress, reaches foundation soil；

2nd, A blocks are the fourth class side prismatic table shape blocks being parallel to each other；B blocks are the chamfered edge stage bodies for catering to A blocks, and conjunction is carved in A in B blocks side face On block；

3rd, the load transmission on B blocks, is the rigidity characteris for utilizing concrete material, by four sides of block with carving face " jumping characteristic " Pass to four A blocks；

Beneficial effect：

It is bigger than discrete material bed course angle of flare, can be with smaller cushion thickness, satisfaction reaches the stress intensity of soil and is less than Permissible value；

Specific embodiment：

Example 1：

1st, three layers of laying of AB blocks point, in one A bricks position of transverse direction mistake, such as Fig. 9, Figure 10；

2nd, spread between the AB blocks of layering it is wet pour compacting sand, thick 80mm, ground floor AB blocks top surface to the third layer AB block bottom surface discrepancy in elevation= 0.08*5=0.4 rice；Block size is marked by accompanying drawing 1 ~ 8；

3rd, 104 in such as Figure 10 are fixed in the mutual position of AB blocks, and in place, AB blocks are mutually carved with block with dryness element concrete, block is filled out with paving Layer side surrounding will be fixed accordingly；

4th, when a certain A block of the Action of Vertical Loads on ground floor AB blocks, load-bearing area at this moment is=0.015m2, AB blocks Three layers of bottom surface load-bearing area is=0.593m2, amplification=0.593/0.015=39.5（Times）

5th, by load angle of flare=29.99 degree of H-H profile directions, by load angle of flare=49.86 degree of K-K profile directions；

Example 2：

3rd, 104 in such as Figure 10 are fixed in the mutual position of AB blocks, and dryness element concrete is filled out with paving with paving, and accurate phase is ensured between block and block Carve in place, AB block layers side surrounding is accordingly fixed；

4th, when B block of the Action of Vertical Loads on ground floor AB blocks, load-bearing area at this moment is=0.03m2, third layer AB block Bottom surface load-bearing area be=0.978m2, amplification=0.978/0.03=32.6（Times）

5th, by load angle of flare=34.09 degree of E-E profile directions, by load angle of flare=54.6 degree of F-F profile directions；

Example 3：From example 1 and the comprehensive analysis of example 2

1st, the H-H profile directions of example 1 are exactly the E-E profile directions of example 2, so, the load angle of flare difference in this direction It is 29.99 degree and 34.09 degree, gets the small value, is exactly 29.99 degree；For convenience, hereafter referred to collectively as X-direction；

2nd, the K-K profile directions of example 1 are exactly the F-F profile directions of example 2, so the load angle of flare in this direction is respectively 49.86 degree and 54.6 degree, get the small value, be exactly 49.86 degree；For convenience, hereafter referred to collectively as Y-direction；

3rd, in real work, with AB blocks in itself judging direction, A blocks are equilateral prismatic blacks, with the diagonal line of length as Y-direction, With short diagonal line as X-direction；When road cushion is paved, the sideline of road is parallel with X-direction, the cross-sectional direction of road with Y-direction is parallel, and such pendulum builds more effective；In the same manner, for other building foundations, long side direction and the X-direction on basis are put down OK, short side direction is parallel with Y-direction, and so pendulum builds high efficiency；

4th, in real work, prefabricated section will match somebody with somebody " binding character " stirrup；Stirrup size and the concrete size of AB blocks, strength mark etc., Will be according to the condition design such as the load intensity of structure upper and building importance；

Example 4：

City excavated pavement, it is the regular affairs of item to update underground utilities, recovers road surface work hardly possible and quality Customers ' Legal Right, is to work as A front difficult problem；The characteristics of removing and recover convenient strong with quality controllability using AB blocks bed course, simplifies work and simultaneously can guarantee that road surface Quality of recovery；

Example 5：

1st, because AB blocks are carved mutually tightly, when vehicle hub directly impacts pre- block, pre- block will not be caused under road surface because of unbalance warping The concentrated stress on basis and the destructions such as drum deformation are played on the road surface that produces, so also properly directly doing concrete precast block common grade Road surface；And because removing and updating convenient, road upkeep cost can be reduced；

2nd, in implementation process, AB blocks do bed course when also doing road surface, the AB blocks on road surface and the AB blocks of bed course, it is proposed that point two kinds of specifications Size and intensity, the destruction that Vehicular vibration brings is reduced with different rigidity；

3rd, the AB sides on road surface will add bevelling to remove corner angle, reduce the brittle break of vehicular impact；

4th, for driving vehicle is to the blind shaft cover impact failure phenomenon in the middle of road, the absolute altitude of blind shaft cover can be reduced, is arranged at In AB block bed courses, it is to avoid direct impact failure of the vehicle to well lid and the road surface in well lid week, but little is affected on pipe-line maintenance；

Implementation result：

1st, the general value of common bed course angle of flare is 30 degree or so, therewith AB blocks diffusion angular difference 49.86-30=19.86 degree, AB blocks Bed course effect is significant；Various types of building construction foundation engineering and road engineering is can be widely applied to, foundation engineering amount, drop is reduced Low construction costs and guarantee construction quality；

2nd, road engineering is applied to, updates can road upkeep convenient and reliable.
