Problems solved by technology

Due to the small number of windows, it is difficult to put the concrete into the warehouse, and the water vapor cannot be completely discharged when the concrete is vibrated; in addition, due to the machining accuracy of the window formwork, the concrete surface has a slight protrusion after the formwork is removed, which affects the appearance quality of the concrete and the water flow rate.

Embodiment Construction

[0012] When designing the inner formwork, it is divided into two parts: the inner formwork skeleton 1 and the sealing formwork 2. The panels between the two are flush with each other and connected by a half tenon. Sliding rails for templates.

[0013] Process Description:

[0014] (1) Construction preparation and installation of internal formwork skeleton: according to the size and position of the designed aqueduct, install the construction load-bearing bent frame, install the external formwork, bind the steel bars, and then install the internal formwork skeleton;

[0015] (2) Hang the half tenon sliding sealing formwork on the corresponding full-length working window, pay attention to not hanging the bottom 2 to 4 pieces first;

[0016] (3) Pouring concrete. Send the concrete into the bin through the sealing formwork reserved for the working window, and vibrate it with a vibrating rod with a tip length of 20 cm. If it is inconvenient during the process of entering the silo...

Abstract

A technology for constructing the prestressed large thin-wall concrete flume features that the internal formwork skeleton and the semi-tenon sealing slide formwork are used for the working window for making said flume, and in the working window the ultra-short (200 mm or less) tamper is used. Its advantage is good sealing to prevent concrete leakage.

Description

Technical field [0001] The invention relates to concrete structure construction of civil engineering, in particular to a construction method of thin-walled concrete prestressed concrete aqueduct working window sealing formwork and concrete vibration. Background technique [0002] At present, most of the internal forms used in the construction of thin-walled arc-shaped concrete structures are large formworks with limited working windows. Due to the small number of windows, it is difficult to put concrete into the warehouse, and the water vapor cannot be completely discharged when the concrete is vibrated; in addition, due to the machining accuracy of the window formwork, the concrete surface has a slight protrusion after the formwork is removed, which affects the appearance quality of the concrete and the water flow rate. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a large-scale thin-wa...
