Problems solved by technology

Most of the construction quality is rough, which affects the construction accuracy, and the project quality cannot meet the increasingly higher construction standards. According to the relevant regulations of GB50202-2002 "Code for Construction Quality Acceptance of Building Foundation Engineering", the allowable deviation of the main reinforcement spacing of the reinforcement cage is ±10mm

Embodiment 1

[0034] Embodiment 1: as attached figure 1 As shown, the construction includes the following steps: (1) Prepare the Ω lock 5 and the disk slotted weight pad 4 according to the design size; (2) Determine the location of the main reinforcement 2 of the flood control wall; (3) Use the Ω lock 5. Lock the main ribs 2 at the inner and outer sides; (4) The main ribs 2 at both ends of the inner and outer sides are locked with the Ω lock 5 connected to the galvanized steel pipe 6 to form a fixed frame. (5) After the main reinforcement 2 is placed, measure the control line of the distribution reinforcement 1 with a tape measure and draw it with chalk; (6) Bind the distribution reinforcement 1 to the main reinforcement 2 in sequence; ( 7) Buckle the prefabricated disk slotted weight pad 4 at the designated position of the main reinforcement 2; (8) Take out the Ω lock 5 with the galvanized steel pipe 6 from the main reinforcement 2; (9) Check the positioning of the reinforcement and the ov...

Abstract

Precise omega-type full lock positioning method for reinforcement of flood control wall implements the space position firstly, and by using omega-type lock catch (5) to fix the galvanized steel pipe (6) and install and make framework, the disc slot type weight pad (4) is prefabricated and then is used for supporting and fixing the concrete protective coating and implementing the thickness positioning of the protective coating; the prefabricated disc slot type weight pad (4) is additionally provided with perforated screws for fixing, the galvanized steel pipe (6) and the omega-type lock catch (5) is token out before the pouring of concrete, while the disc slot type weight pad (4) is remained in the concrete; the framework is fixed firstly, and then the colligation or the welding is implemented, and the stability of the stereotyped reinforcing bar is improved effectively; in the dismantling of later period, only the fixing units is removed, thereby the locator can be dismantled rapidly, and the locator and related auxiliary tools can be reused. Besides, the overall aesthetic of the stereotyped reinforcing bar is better.

Description

technical field [0001] The invention relates to the bottom plate and wall structure technology of the flood control wall of the water conservancy project, which belongs to the special sheet pile wall, pile or other structural member technology of the E02D5 / 00 foundation engineering in the IPC classification, especially the Ω-type full lock positioning method for the precise determination of the reinforcement of the flood control wall and locators. Background technique [0002] The number and scale of water conservancy projects are getting larger and larger. During the construction process of traditional water conservancy construction methods, especially for the finalization or positioning of the reinforcement structure of the flood control wall, it is mainly based on manual operations. On the construction site, welding, pipeline construction, and lightning protection construction are required It is necessary to embed steel bars during the construction process, but the positi...
