Abstract
A subgrade and pavement whose cost is basically comparable to or less than that of high-grade 4-lane highway (including small culverts and small or middle bridge) features use of hollow concreat I-shaped beam, small-span T-shaped connecting beam, longitudinal open-spandrel wall-type arch, thin arch, or ring arch according to qualities of different segments.
Description
The present invention relates to a kind of highway subgrade road surface, the particularly a kind of and essentially identical structure of highway subgrade road surface cost.
Repair the roads and to account for the arable land.Problem is how to account for the arable land to the greatest extent less.The Four-Lane Road high-grade highway takes up an area of wide 42M.It is great to account for quantity of cultivated land.
It is common to all to replace roadbed (highway contains the road surface) to account for the arable land less with structure (bridge of various structural shapes, culvert general name), the sole cause of failing to implement is that structure cost height is bound to arouse fear, artificial, material, machinery expense as Four-Lane Road High-Grade Highway Subgrade road surface add up to (being called for short road labor and materials machine adds up to) to be 200 yuan every square metre (not containing expenses such as sapce charge, foot bridge culvert), and artificial, the material of the little bridges and culverts of modern idea, machinery expense reach every square metre and be 600-1200 unit.Cost differ great disparity like this be save to plough be purpose replace the impracticable sole cause of subgrade and pavement with structure.
The present invention has changed modern bridges and culverts idea, break through the structure existing capability, break away from traditional habit, can make and stride short structure cost for a short time to drop to amazing low-level and existing standard subgrade and pavement cost close, even the worker of the structure that has, material, machine add up to than road worker, material, machine and add up to also low 20%.
The objective of the invention is to account for the arable land less, the cost of structure is dropped to and existing close, the perhaps lower a kind of highway structure of standard subgrade and pavement cost in realizing the highway modernization construction.
The present invention is achieved in that the low subgrade and pavement of cost that adopts hollow bricklaying, little cross T-shaped continuous beam, vertical arch of wall formula on an empty stomach, the thin arch ring of cement concrete to connect and compose according to different geology highway sections.Its both sides at subgrade and pavement have safety barrier.
Make highway subgrade with hollow bricklaying 3 (cement concrete or the stone-laying of cement bonded sand oar), upper berth Portland Cement Concrete Surface Course 1, divide into the bed course 4 that connects with soil matrix, cross flow water on the arable land freely passes through in hollow hole 2, need not roadside ditch, land surface can equate with the elevation of hollow hole 2 bottom surfaces, also difference slightly.The lower edge of hollow bricklaying 3 and Portland Cement Concrete Surface Course 1 should add distributing bar.
Bottom reinforced concrete pile 7, the top little cross T-shaped continuous beam 5 of steel concrete, the fulcrum place establishes steel concrete crossbeam 6.Cross flow water on the arable land can freedom cross flow under bridge need not roadside ditch.
The bottom is encircleed (also can claim arch rib) with bricklaying (cement concrete or the stone-laying of cement bonded sand oar) basis 8, bricklaying pier 9, top with the wall formula, it is 11 thick that abutment wall formula arch 10 middle wall formulas are encircleed, it is 11 fixed for whole that little arch 13 and abutment wall formula arch 10 and middle wall formula are encircleed, upper berth Portland Cement Concrete Surface Course 1.Steel concrete crossbeam 6 spacings are suitable littler, so that mobile load is evenly distributed.Abutment wall formula arch 10 and middle wall formula arch 11 should add main muscle and stirrup, and Portland Cement Concrete Surface Course 1 should add the structure muscle.
The bottom is filled out abdomen stone 15 with the thin arch ring 14 of cement concrete, soffit with low strength cement sand oar block with bricklaying (cement concrete or the stone-laying of cement bonded sand oar) basis 8, bricklaying pier 9 tops, the surface concrete pavement 1 that lays cement.The thin arch ring 14 of cement concrete is joined the structure muscle, and vault is joined principal rod, and the reinforcing bar amount must be calculated decision.
The present invention can make the cost on structure and existing standard Four-Lane Road High-Grade Highway Subgrade (containing the less jackshaft of little bridges and culverts and part) road surface, and close (structure that has also hangs down about 20% than existing standard, reach not only feasible with structure replacement high-grade highway, highway administration department also has interests to get.
According to the geological hydrology condition difference on a road, make its some harder locations be suitable for hollow masonry structure, take up an area of wide 23.7M (below the Four-Lane Road all with) cost and equal the 96-80% of existing standard.
Face of land 1M is following to be the pan soil interval, is fit to vertical open web type arch and approaches the arch ring arch, takes up an area of wide 23.7M, and cost equals the 102.5-98% of existing standard, and area can utilize 30.60 to 80% but encircle down.
Ground soil property pine is dredged the highway section, is suitable for the little cross T-shaped continuous beam of pile foundation, and cost equals 102.3% of existing standard, and it is suitable to can be considered cost.The wide 23.7M in some ground can utilize 30.60 to 90% under the bridge.More than, when utilizing 30%, 60%, 90% under the bridge, close and take up an area of wide be 16.6M, 9.5M, 3.4M.
Below specific embodiments of the invention are done to describe in detail.See shown in Fig. 1-7.
Embodiment 1, sees shown in Figure 1.
Fig. 1 is hollow bricklaying subgrade and pavement side status schematic diagram.
Take hollow bricklaying 3 structures in the hard highway section of soil property.Original ground is carried out the vertical and horizontal section adjustment, make its face of land longitudinal section parallel with vertical disconnected design lines, adjusted cross section is a level, matting layer 4 thereon, (and look construction seasons and geology soil class bed course 4 can attenuate or can remove from) leveling, compacting, prop up upright pipe of cement inner formword, and make and bed course 4 (or soil matrix) between the size of design is arranged, leave certain spacing between each pipe of cement inner formword, carry out bricklaying 3 constructions then, casting cement concrete or carry out the stone-laying of cement bonded sand oar, make bricklaying 3 reach design size, leveling back casting cement concrete pavement 1 at the top of pipe of cement inner formword.
Embodiment 2, see shown in Fig. 2,3.
Fig. 2,3 is little cross T-shaped continuous beam and A-A profile status schematic diagram.
Ground soil property pine is dredged the highway section, little cross T-shaped continuous beam 5 is got on top, reinforced concrete pile 7 is adopted in the bottom, with machinery reinforced concrete pile 7 is driven into design altitude, the template of the cross T-shaped continuous beam 5 of Zhi Lixiao, steel concrete crossbeam 6, put the cast-in-place cementing of reinforcing bar and coagulate soil, wherein contain cement and mix native surface layer 1.
