Abstract

The invention provides a construction method of an inverted trapezoidal open channel, wherein the open channel comprises a channel and a channel bottom wall and a second channel side wall which are encircled to form the channel, wherein the construction method comprises the following steps of implementing an unprotected open cut excavation to form a groove bottom wall and a second groove side wallarranged at both sides of the groove bottom wall; embedding reinforcing steel bars, and binding iron wires on the reinforcing steel bars; pouring a concrete cushion to form the channel bottom wall; laying two opposite connecting rods and reinforcing transverse rods on the concrete cushion, wherein the plurality of transverse rods are connected with the reinforcing steel bars through the iron wires; installing a second lateral template, and the second lateral template is respectively defined between the two adjacent side walls of the two grooves to form a pouring space of the channel side wall; installing an inverted trapezoidal plate; casting the concrete into the first concrete space to form the channel side wall; curing the concrete and removing the template.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an inverted trapezoidal open channel construction method. Background technique [0002] Although the construction of drainage facilities on the building site is simpler than the main structure, it also has its corresponding construction difficulties. The biggest difficulty lies in how to ensure that the open channel formwork has sufficient anti-floating performance during concrete pouring and improve the stability of the formwork. Contents of the invention [0003] In view of the above situation, the present invention provides an inverted trapezoidal open channel construction method to solve the technical problem that the formwork is not firmly fixed during the existing open channel construction process. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: provide a kind of inverted trapezoidal open channel co...
