Cast-in-place canal one-time forming construction method of rolling type forming machine

Abstract

The invention relates to the field of canal construction, and particularly discloses a one-time forming construction method for a cast-in-place canal by a rolling type forming machine, which comprises the following steps: step 1, surveying and setting out, and marking the excavation position of the canal; 2, digging a canal trench according to the marked position; step 3, preparing a concrete mixture; and 4, casting the concrete mixing material in place, curing and forming to obtain the water channel. Wherein the concrete mixture comprises the following components in parts by mass: 440-450 parts of cement; 140 to 150 parts of water; 100 to 150 parts of sand; 100 to 120 parts of slag; 120 to 150 parts of vesuvianite powder; 50 to 70 parts of nano silicon dioxide; 15 to 20 parts of konjaku flour; and 30-40 parts of water glass. The concrete mixture is used for casting the water channel in situ, so that the concrete mixture is convenient to cast and form, and the compressive strength of the water channel formed by casting the concrete mixture is guaranteed.

Description

technical field [0001] The invention relates to the field of canal construction, in particular to a construction method for one-time forming of a cast-in-place canal by a rolling forming machine. Background technique [0002] Aqueducts are man-made waterways, usually made of stone or cement. Aqueducts can realize water diversion in space, maintain an even distribution of water resources, block floods when they come, prevent danger, and effectively preserve water resources. They are currently an important infrastructure for people's lives. [0003] In order to reduce the trouble of manually building formwork and removing formwork, the current canal construction generally utilizes a rolling canal automatic forming machine to cast in-situ concrete and form it at one time. However, it is necessary to prepare the concrete mixture on site firstly by using the rolling type automatic forming machine for pouring concrete, then add the prepared concrete mixture into the rolling type ...

Problems solved by technology

However, it is necessary to prepare the concrete mixture on site firstly by using the rolling type automatic forming machine for pouring concrete, then add the prepared concrete mixture into the rolling type automatic forming machine, and then use the rolling type automatic forming machine to cast the concrete mixture And curing molding, when the concrete mixture is added to the automatic rolling channel forming machine and waiting to be poured, because the density of the aggregate in the concrete is higher than that of the water ash material, the aggregate is waiting to be poured in the rolling channel automatic forming machine It is easy to deposit to the bottom of the concrete mixture during the process, which will easily cause the concrete mixture to bleed, and then the compressive strength of the water channel formed by pouring will be easily affected. Therefore, there is still room for improvement
