Embodiment

[0035] Taking the China-Myanmar oil and gas pipeline (Myanmar section) G132+200 pipeline in the Rakhine Mountains as an example to describe in detail. When the G132+200 pipeline was laid on the transverse slope in the Rakhine Mountain area, heavy rainfall caused the rear slope to slide. In order to protect the safety of the pipeline body, anti-sliding piles made of reinforced concrete were poured on the outer slope of the operation zone, and the piles Concrete retaining walls were poured occasionally, but the outer slope of the anti-slide piles continued to slide under the influence of heavy rainfall, and the bottom of the retaining walls and anti-slide piles were at risk of exposure. In order to prevent rainwater from penetrating from the foot of the concrete retaining wall to the joint Underground, PE film is used to waterproof the foot of the concrete retaining wall to achieve the purpose of waterproofing. First, clean the surface of the concrete retaining wall foot that ne...

Abstract

The invention discloses a concrete retaining wall foot waterproof treatment method. The treatment method comprises the following steps that firstly, a wall foot is cleaned, and a first rubber belt isattached; secondly, the first rubber belt is covered with a PE film; thirdly, a second rubber belt is attached to the PE film; fourthly, an iron plate is pressed on the second rubber belt; fifthly, anexpansion bolt is used for fixing; and sixthly, the edge position of the PE film is coated with waterproof glass cement. According to the concrete retaining wall foot waterproof treatment method, construction is convenient, through sequential arrangement of the first rubber belt, the PE film, the second rubber belt and the iron plate, the expansion bolt tightly presses the iron plate so as to press the upper edge of the PE film for fixing, waterproof performance is improved through the two layers of rubber belts, and when the expansion bolt is used for fixing, the deformation of the first rubber belt offsets the uneven surface between the retaining wall face and the PE film, and tight combination is achieved; and the waterproof glass cement is applied to the top end of the PE film according to the shape of the equilateral right triangle, the waterproof effect can be better, the service life is longer, and the concrete retaining wall foot waterproof treatment method is suitable for wide-range popularization and application.

Description

technical field [0001] The invention relates to a method for waterproofing the foot of a wall, in particular to a method for waterproofing the foot of a concrete retaining wall. Background technique [0002] With the continuous development of my country's economy and society, my country's consumption of oil and natural gas is increasing, and oil and natural gas are extracted and transported to the downstream end through oil and gas long-distance pipelines. Long-distance oil and gas pipelines are laid on a transverse slope in the tropics, subtropics, or southern China. If they encounter continuous heavy rainfall, landslides are very likely to occur; for this, anti-slide piles are usually poured on the side slope of the pipeline operation belt to prevent the pipeline from falling. Suffering from the lateral thrust of the landslide body behind. However, if the slope before the anti-slide piles meets the rainy season at the initial stage of the completion of the anti-slide pile...
