A Technical team Of Electric Corporation of Ecuador (Celek) traveled to Mississippi, USA this week to present a physical model of the Jet Grouting Screen System. It seeks to protect the catchment work of the Coca-Codo Sinclair hydroelectric power plant, which is threatened by the erosion process of the Coca-Cola River.

This model is one of a kind Model With real movement aimed at showing how the river would react to structures designed to try to stop it Decay. Natural disasters include construction of a set of works at the bottom of the river, one kilometer below the plant reception, located in Canton. ChakoNapote.

These tasks have three stages (called 0, 1 and 2). Currently there Performance Phase 0, which consists of the construction of a cofferdam or small dam to divert the Koka River, and the first of 14 screens to be built at the bottom of the river, is a kind of step.

This was designed by Lombardi GroupThe death penalty while in charge of the company Accyem project. The preliminary phase started last January and is expected to end in November this year. For this, there is a reference budget of USD 12.1 million. The next step (1) will start as soon as you know the physical model created by the US Army Corps of Engineers.USACE), Which has a cooperation agreement with Celec.

For Carolina Bernal, a professor of geology and National Polytechnic, it is important to know the physical model because the progress of the following stages depends on it. In other words, if the design created by Lombardy does not work with the physical model, it will be unnecessary to continue with it. Construction Of work. “We have to wait and see what happens. What has happened in the country with this erosive process is terrible,” Bernal added.

From Selek Details will be known when the technical team returns.

The risk posed by the catchment is not the only threat caused by natural phenomena Hydropower Station Coca Elbow Sinclair. Another risk factor is sedimentation in the bottom of the Koka River in front of the central turbine water discharge area, the product of erosion. This could lead to flooding of the power house, which is the epicenter of the hydropower plant.

Distributor failure

Besides, there are thousands of hidden problems Cracks found There are eight pressure distributors in that project. They have at least seven repair processes, but new bugs keep appearing.

Distributors are crucial for the operation of the hydroelectric plant, these teams are inside the powerhouse and have the appearance of huge steel snails, they take water and distribute it to the power generation turbines. A technical report sent to Coca-Codo Sinclair project sub-management, published by MLA Fernando Villavicencio, chairman of the Assembly’s Oversight Commission on April 22, indicates that “the situation of distributors is becoming increasingly serious.” The Assemblyman sent a summary of the document to the President of the Republic, Guillermo Lasso.

For VillavicencioThe fate of this project requires a presidential decision to prevent the country from receiving a job with structural defects. In addition, he has requested an inquiry into the execution and its execution.

The hydroelectric power plant is the largest in the country, with an installed capacity of 1,500 megawatts, located between the provinces of Napo and Sucumbios, and has cost more than USD 3,300 million. Since its inauguration in 2016, it has not been able to function normally due to the lengthy repair process.
