Canal slope cast-in-place concrete composite additive and preparation method thereof
The invention discloses a channel side slope cast in situ concrete composite additive, and a preparation method thereof. The channel side slope cast in situ concrete composite additive comprises, by weight, 25 to 50 parts of a water reducing agent, 1 to 5 parts of an air entraining agent, 5 to 15 parts of a thickening agent, 4 to 20 parts of an early strength agent, and 20 to 60 parts of water. The channel side slope cast in situ concrete composite additive obvious water reducing effect, air entraining effect, thickening effect, and early strength effect, is capable of increasing strength, compactibility, impermeability, and crack resistance of channel side slope concrete greatly, improving construction quality, and prolonging project service life. According to application processes of the channel side slope cast in situ concrete composite additive in channel side slope cast in situ concrete, the admixing amount of the channel side slope cast in situ concrete composite additive only accounts for 0.5 to 1.5% of the total mass of cement in the concrete; cost is relatively low; economic benefit is excellent; and the channel side slope cast in situ concrete composite additive is suitable for large-scale popularization.

Arched retaining wall structure of a river course and its construction method
ActiveCN104499502BHigh compressive strengthSave materialArtificial islandsBreakwatersEconomic benefitsCut and fill
The invention discloses a riverway arch retaining wall structure and belongs to the field of traffic and marine traffic engineering. The riverway arch retaining wall structure comprises buttress piers and a retaining wall, the retaining wall is formed by side-by-side connection of a plurality of circular arc wall bodies, two ends of each circular arc wall body are fixed on the buttress piers, circular arc protruding portions point to the earth filling direction, the protruding side of the retaining wall is filled with earth to form an earth-filled layer, and the space between the retaining wall and the earth-filled layer is filled with a rubble layer. Tie bars are arranged in the earth-filled layer horizontally, and one end of each tie bar is connected with the corresponding buttress pier while the other end is fixed through a fixing column. Plastic blind ditches are horizontally arranged in the earth-filled layer layer by layer. The outer side of each plastic blind ditch is coated with geotextile. The invention further discloses a construction method of the retaining wall structure. By the structure, deformation resistance and overall stability of the retaining wall are enhanced greatly, water in filled earth on the rear side of the retaining wall can be drained quickly, earth pressure on the retaining wall is lowered, and the construction method is simple in construction technology and remarkable in economic benefit.
