Abstract
The utility model discloses a Yudong plain county rural highway cement concrete pavement structure, which comprises a surface layer, and a base layer in a three-layer or two-layer structure, wherein the surface layer adopts the cement concrete, and the base layer adopts the cement stabilized soil or gravel, lime stabilized soil or gravel soil, cement and lime stabilized soil, cement stabilized crushed stone, graded gravel and natural gravel. The typical pavement structure of the utility model enables the pavement structural design to be standardized and charted, has convenient use, greatly shortens the cycle of the design, reduces the design workload, improves the work efficiency and saves the design cost.
Description
Technical field
The utility model relates to the highway pavement structure, especially relates to the Henan former counties and townships highway cement concrete pavement structure of conquering east.
Background technology
Henan conquers east that the problem that exists in the highway construction of former counties and townships is that grade is low, road conditions are poor, local road structure use single, lack maintenance, lack problems such as effective quality, technical management, show that mainly roadbed, pavement compaction degree are not enough, side slope is stable inadequately, the gutter excavation is lack of standardization, the barricade instability, the road surface multiple labour of exceeding the time limit, the subgrade and pavement disease is more, the road conditions quality is lower, adding a certain period of traffic increases suddenly suddenly, the particularly increase of heavy load causes road surface and bridge collapse to speed up, and harm is serious.As because of arterial highway project under construction enclosure portion road section traffic volume, counties and townships' traffic volume of highway of periphery is increased, heavy load increases, and substantially exceeds the accumulative equivalent axles of design, has therefore reduced service life and life-span.Though some substandard highways are through transforming for many years, many highway sections still do not reach the technical standard requirement, bring many sequelae to maintainer.The road surface breakage situation is serious, has almost contained all types of damage of flexible pavement.Some highway sections are surveyed deflection value in fact and have been surpassed design deflection value in actual useful year.Lack maintenance, it is low that counties and townships' highway pipe is supported rate, and it is big that difficulty is carried out in administration of highways work, lacks effective quality, technical management, and some basic technical problems are still restricting the raising of workmanship so far.As basic unit's stability problem of cement concrete pavement etc., in counties and townships' highway construction, mostly do not obtain due attention.The counties and townships' highway that has is direct overlay table place surface layer in weak basic units such as rendzinas or plaster knot rubble, is difficult to stand vehicular load and sleet and corrodes.Some places even some jejune construction technologies being applied to blindly caused workmanship hidden danger in the construction.
Summary of the invention
The technical problems to be solved in the utility model is: under China's pavement design standard instructs, weather, soil geological conditions and material source etc. according to an area carry out rational road structure design, make road structure design specificationsization, pictorialization, reduce the design work amount, optimize the road structure design, make aspects such as the road structure designer selects at material, thickness is determined that bigger range of choice be arranged, thereby determine road structure safe and reliable, economical rationality.
The technical solution adopted in the utility model is: this Henan former counties and townships highway cement concrete pavement structure of conquering east is to adopt three layers or two-layer structure of surface layer and basic unit, and surface layer adopts cement concrete, and basic unit adopts cement and lime soil or rendzinas.
As one of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 22cm, and basic unit is 10% a thick rendzinas of 12% thick rendzinas of 16cm and 16cm.
As two of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 20cm, and basic unit is 10% a thick rendzinas of 12% thick rendzinas of 18cm and 18cm.
As three of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 22cm, and basic unit is 10% a thick rendzinas of thick cement and lime soil of 15cm and 16cm.
As four of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 20cm, and basic unit is 10% a thick rendzinas of thick cement and lime soil of 15cm and 18cm.
As five of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 20cm, and basic unit is 10% a thick rendzinas of 12% thick rendzinas of 18cm and 15cm.
As six of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 18cm, and basic unit is 10% a thick rendzinas of 12% thick rendzinas of 16cm and 15cm.
As seven of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 20cm, and basic unit is 12% a thick rendzinas of 15cm.
As eight of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 18cm, and basic unit is 12% a thick rendzinas of 15cm.
As nine of technical scheme optimal way is that the surface layer of cement concrete pavement structure is the thick cement concrete of 16cm, and basic unit is 12% a thick rendzinas of 15cm.
The technique effect that the utility model produces is: adopt typical road structure of the present utility model, make the road structure design specificationsization, pictorialization, form is eye-catching, with strong points, easy to use, shortened the design cycle greatly, reduce the design work amount, improved operating efficiency, saved design cost, improve workman's construction technology qualification, prolong road application life, investment promotion is effectively balanced and the road structure designer is selected at material, there is bigger range of choice aspects such as thickness is definite, do not need to do big calculating and just can determine safe and reliable, the road structure of economical rationality, thus avoid owing to the structure selection improper or thickness to determine that the improper road structure that causes is uneconomical or dangerous.
