Description

A kind of Desulphurization roadbed cement pavement structure
Technical field
The utility model belongs to highway construction technical field, particularly relates to a kind of Desulphurization roadbed cement pavement structure.
Background technology
Along with the environmental requirement of domestic power plant promotes, the generally utilization of desulfur technology, cause infant industry waste material Desulphurization output significantly to increase, Desulphurization is arbitrarily piled up and is not only endangered environment, also causes the wasting of resources.How fully to utilize Desulphurization material efficiently, play the physicochemical characteristics of Desulphurization, solve practical problem in engineering construction, waste residue is become resource, significant.
Traditional cement pavement structure, due to the different qualities of roadbed and surface layer, roadbed and surface layer are difficult to combine closely, and cause road surface resistance to overturning poor, road surface supporting capacity is lower, all bring impact in various degree to the quality of road, life and reliability.
At present, cement pavement is many to be made up of jointly Portland Cement Concrete Surface Course and roadbed, and roadbed is generally cement stabilized soil roadbed or cement stabilized macadam material roadbed.There is the deficiencies such as working procedure is many, application life is short, integrated cost is higher in this kind of cement pavement.Meanwhile, during construction after roadbed reaches standard compaction degree, directly pave Portland Cement Concrete Surface Course, and due to engineering time, material property difference, roadbed and surface layer are difficult to combine closely and play a role.
Utility model content
For the deficiency that existing rural area cement road exists, the utility model provides the Desulphurization roadbed cement pavement structure that a kind of basic unit and surface layer can be combined closely, and can be used as rural area cement road.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Desulphurization roadbed cement pavement structure, the Desulphurization roadbed (3) comprising cement concrete pavement layer (1), gantry type link (2) and be layed on Portland Cement Concrete Surface Course (1), gantry type link (2) top is fixed in Portland Cement Concrete Surface Course (1), and its underpart is anchored in Desulphurization roadbed (3).
Above-mentioned Desulphurization roadbed (3) thickness is 650 ~ 1300mm.
Above-mentioned Portland Cement Concrete Surface Course (1) adopts the C25 concrete of thickness 200 ~ 280mm.
Above-mentioned gantry type link (2) adopts fiber glass reinforced polyamide 66 to prepare.
High 70 ~ the 140mm of above-mentioned gantry type link (2), wide 50 ~ 80mm, its underpart is anchored in 40 ~ 80mm in Desulphurization roadbed (3).
At a distance of 60 ~ 80cm between above-mentioned adjacent door posture link (2).
Compared to the prior art, the utility model tool has the following advantages and beneficial effect:
1, adopt Desulphurization roadbed to substitute cement stabilized soil roadbed, have that stability is high, frost resistance is excellent, anti-drying shrinkage ability strong, good endurance, cheap, the advantage that can combine closely with Portland Cement Concrete Surface Course.
2, the utility model road structure can ensure enough strength and stiffness, and have certain elasticity, water stability is excellent, and temperature contracting effect is not obvious, meanwhile, and the impact of the reflection crack that can effectively prevent Portland Cement Concrete Surface Course from bringing.
3, adopt gantry type link to act between Portland Cement Concrete Surface Course and Desulphurization roadbed, Portland Cement Concrete Surface Course and Desulphurization roadbed can be combined closely more.
4, take full advantage of industrial waste Desulphurization, avoid Desulphurization and arbitrarily pile up the environment pollution caused, energy-conserving and environment-protective.
5, can be applicable to make rural area cement road.

Wherein, 1-Portland Cement Concrete Surface Course, 2-gantry type link, 3-Desulphurization roadbed, 21-crossbearer, 22-vertical frame.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete structure of the present utility model is described further.
See Fig. 1 ~ 2, the utility model structure comprises Portland Cement Concrete Surface Course (1), gantry type link (2) and Desulphurization roadbed (3), Portland Cement Concrete Surface Course (1) adopts the concrete of C25 intensity, thickness 240mm; Desulphurization roadbed (3) thickness 1200mm.According to actual needs, Desulphurization roadbed (3) bottom is compacted subgrade layer, i.e. road cushion, be made up of the bulk particulate materials such as coarse sand, gravel, rubble, cinder, slag or cement, lime cinder etc. stablize closely knit bed course.Meanwhile, Desulphurization roadbed (3) thickness can adjust in proper range according to Rock Conditions.Fig. 3 is gantry type link schematic diagram, comprises crossbearer (21) and two vertical frames (22), and the first vertical frame and the second vertical frame are connected crossbearer (21) two ends and vertical with crossbearer (21) respectively.In this concrete enforcement, crossbearer (21) and vertical frame (22) all adopt the fiber glass reinforced polyamide 66 (nylon66 fiber) of high strength to manage.
The laying method of the utility model Desulphurization roadbed cement pavement is described below in conjunction with specific embodiment:
Step 1, the preparation before embankment:
Compacted subgrade layer is cleaned out, and rolls before carrying out embankment, make compacted subgrade layer reach the degree of compaction standard of regulation.
Step 2, Desulphurization prepares:
For ensureing the stability of Desulphurization roadbed (3) and enough intensity, curing compound need be added in Desulphurization.Carry out Mix Ratio Test, determine Desulphurization subgrade construction match ratio, in this concrete enforcement, Desulphurization and curing compound mass ratio are 17:1, and Desulphurization water content control is 34 ~ 38%.Desulphurization and curing compound are carried out mechanical mixture, then adds water and stir.
Step 3, pave Desulphurization:
Desulphurization roadbed adopts horizontal slice filling construction, when being divided into different work section and filling, first fills out section and answers layering to stay step, make the overlapped overlap joint of each compacted lift, ensure the degree of compaction within the scope of adjacent job step joint.
Step 4, flattens and rolls:
Desulphurization after paving must roll in time, and accomplishing to pave the same day, it is complete to roll the same day.When rolling, Desulphurization should be made close to optimum moisture content.
Step 5, place gantry type link:
Gantry type link size is determined, then by also anchoring in five of gantry type link height/three embedded Desulphurization basic unit according to category of roads and requirement.This is concrete implements, and any gantry type link adjacent door posture link all around and this gantry type link are all at a distance of 70cm.
During anchoring, according to pre-determined gantry type link size and anchoring particular location, adopt auger to bore anchor hole in each anchoring place, anchor hole is directly about the 2-2.5 of vertical frame (22) diameter doubly, the degree of depth is about 3/5 of gantry type link height, cement injection mortar in anchor hole; Then, gantry type link is inserted in the cement mortar in anchor hole, and two of gantry type link vertical frames (22) is all placed in anchor hole centre position as far as possible, treat that cement mortar is solidified.
Step 6, lay Portland Cement Concrete Surface Course:
Portland Cement Concrete Surface Course is laid as requested with specification.
