Construction scheme of paving floor tiles on sidewalks

Before the construction of concrete cushion, clean up the sundries and eluvial soil on the basement floor; Lime soil should be compacted, excavated above the ground elevation, filled and compacted with gravel below the design elevation. Each working procedure of concrete construction is controlled as follows:

① Control of raw materials entering the site: the concrete is stirred by drum mixer. Product certificate shall be provided when entering the site, and standard test blocks shall be made on site. ?

(2) The formwork shall be made of wood pattern, and the isolation agent shall be brushed before installation. Pay-off, positioning and correction shall be carried out during installation, and concrete shall be controlled.

Elevation, the thickness of the pop-up elevation control line. ?

(3) Strictly control the slump in the cast-in-place construction, and the concrete will be used up within 2 hours. Concrete shall be poured and vibrated by vibrator to ensure the compactness of concrete. ?

(4) After concrete pouring is completed, prominent stones or uneven places should be leveled. Finally, check the flatness with a ruler, and polish it manually after it meets the requirements. ?

(5) After completion, block the traffic to prevent people from stepping on and running over the floor. ?

6. Masonry should be carried out in sections. The zoning section should be divided according to the position of deformation joint and the joint position between the ground and different materials. ?

Preparation for sidewalk construction:

① Preparation of the lower bearing layer: Before laying colored bricks on the sidewalk, check the elevation and quality of the base layer by layer, and deal with those that do not meet the requirements. ?

(2) Construction lofting: height control lofting is carried out according to the cross slope, and plane size lofting is carried out according to the pattern shape of the block surface.

The choice of sidewalk colored bricks?

The compressive strength of cement concrete precast sidewalk blocks meets the design requirements, the anti-skid grade meets the requirements, the wear resistance is good, and the water absorption rate is not more than 8%.

The surface of the block shall be smooth and rough, with smooth roads and neat edges and corners, and there shall be no honeycomb, exposed stones and peeling. Color paving brick color should be uniform, can not have obvious color difference and noise. Block specifications, thickness difference, flatness and verticality deviation should be within the allowable range.

Colored bricks should be produced by the manufacturer, with factory certificate, production date, raw materials, mixture ratio, flexural, tensile and compressive strength test results and wear resistance test report.

Extended data:

According to its functions, sidewalks can be simply divided into five parts: kerbs, functional belts of ancillary facilities, blind roads, sidewalks and concession lines. Although each part seems simple, it plays a very important role in urban roads. As long as these five parts are reasonably integrated and perfected, they can play a higher role.

In a modern city with an inch of land and gold, the problem of land use always restricts the development of the city, especially in the construction of urban infrastructure, the problem of land use demand and urban development reserve is inevitable. The use of sidewalk space in urban roads is becoming more and more obvious. Underground is the "base camp" of various pipelines, which is occupied by pipelines such as street lamps, power supply and communication.

The ground is the "base" of various ancillary facilities, which is occupied by greening, advertising, newsstands and other facilities. The use of sidewalks is unstoppable. Therefore, the limited space of sidewalks must be reasonably and fully utilized.
