Embodiment Construction

[0031] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0032] see figure 1 , is a field concrete pavement construction method of the present invention, as shown in the figure, the method includes the following steps, construction preparation S100, mixing concrete S102, paving concrete S104, rolling S106;

[0033] The construction preparation includes the steps of clearing the soft foundation soil, leveling the base, and installing measurement control piles on the base every 10m to ensure the smoothness of the road surface. The measurement control piles are mainly used to control the elevation.

[0034] The mixing concrete includes steps of mixing 270-330kg of 32.5R Portland cement, 0.25-0.5mm medium sand of 0.43-0.51m 3 , 20-40mm gravel 0.76-0.92m 3 , fly ash 0.06-0.08m 3 Mix the concr...

Abstract

The invention provides a field concrete pavement, a building method and concrete. The method includes the following steps of construction preparation, concrete stirring, concrete paving and grinding. Construction preparation includes the steps that soft foundation soil is removed, a base layer is leveled, and measurement control piles are arranged on the base layer. Concrete stirring includes the steps that 270 kg to 330 kg of 32.5 cement, 0.43 m<3> to 0.51 m<3> of medium sand, 0.76 m<3> to 0.92 m<3> of gravel and 0.06 m<3> to 0.08 m<3> of coal ash are stirred, and the concrete of each disc is stirred for 160 s to 200 s. Concrete paving includes the steps that the base layer is wetted, and the concrete is paved through a land leveler. Grinding includes the steps that vibration initial grinding is conducted 1 to 2 times, non-vibration repeated grinding is conducted 1 to 2 times, and a pneumatic tire roller is then adopted for finial grinding. By the adoption of the field concrete pavement, the building method and the concrete, the purpose of filed concrete pavement building is achieved.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a field concrete road construction method, road and concrete. Background technique [0002] The land consolidation project in our province started in 2005, and it has been 11 years. The previously designed mud-bound gravel pavement was basically damaged after several years of use. [0003] The mud-bound macadam pavement of field roads mainly has the following problems: [0004] (1) Poor resistance to rain erosion, poor resistance to natural disasters, [0005] (2) After the agricultural machinery runs, the road surface is severely damaged. [0006] (3) It is difficult to supervise the construction quality, and it is easy for the construction party to cut corners. [0007] (4) It cannot be used on soft ground in the field. Contents of the invention [0008] For this reason, need provide a kind of novel field concrete pavement construction method, solve the above problems ...
