A construction method and device for a gate slot

Abstract

The invention designs a gate slot construction device, which is used for realizing rapid gate slot construction of a gate by adopting a mechanical process. The device is provided with a gate slot positioning and clamping mechanism and a steel template, wherein left and right side members of each section of gate slot are connected with a climbing mechanism; after a gate slot is arranged, the lower end of the gate slot is kept fixed; a gate slot pouring space is closed by using the steel template, and concrete is poured; and the gate slot climbing device climbs by one section after one layer of concrete is poured every time. A truss structure in a novel gate slot construction device for the gate has the characteristics of high overall rigidity, high reliability and generality in a certain size range, so that the conventional open air dangerous operation way is turned into a way which is centered by highly mechanical assembly operation and assisted by manual operation, the construction safety and quality of a gate slot for a planar gate or an arc-shaped gate are guaranteed easily, and maximization of an engineering economic value is realized through a rapid construction way.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower engineering construction, and relates to a method and a device for installing gate grooves and rapid concrete construction. Background technique [0002] In water conservancy and hydropower projects, gates and gate slots need to be installed to retain water or adjust water flow. The existing gate channel steel structure embedded parts attached to gates usually adopt the second-stage concrete installation method. This method is easy to ensure the installation quality. However, the construction procedures are complicated, the period is long, and the measures to ensure the safety of the operation are complicated, which often restrict the construction of the project. For example, in the tunnel diversion project of a hydropower station or the part of the dam diversion project where the height of the door slot is large, the existing second-phase concrete installation method is to clean th...

AI Technical Summary

Problems solved by technology

Because most water conservancy and hydropower projects now use large-area steel formwork for rapid concrete construction, the disadvantage of the second-phase installation method of the door slot is that due to the small working space, there is currently a lack of effective mechanical means to assist construction, which not only leads to the construction progress The problem of slowness, safety hazards caused by high-altitude operations are unavoidable, and water leakage often occurs due to the poor quality of the bonding surface between the first-stage and second-stage concrete

In order to optimize the construction, a method of installing the door slot with concrete in the first stage was produced, such as adding support materials to the door slot for reinforcement in the first phase, and using the gate body as a support to install the door slot, etc., because the embedded structure of the door slot, Installation quality requirements and the relationship with related concrete pouring construction require a large investment in manpower and material resources on site, and cannot achieve mechanized and efficient operations comparable to concrete pouring. Previously, it was only used in small-sized door slots
