Construction process of concrete form water-stopping occlusion pile

Abstract

The invention relates to a construction process of a concrete form water-stopping occlusion pile. The construction process comprises the following steps: constructing a plain concrete pile, and using a special occlusion form to form cambered grooves; and constructing a reinforced concrete pile, wherein concrete automatically flows into the cambered grooves of the plain concrete pile at the moment, thereby realizing the occlusion of the plain concrete pile and the reinforced concrete pile to form a curtain so as to achieve the purposes of water stopping and water retaining. Compared with the prior art, the invention has the advantages that the construction cost is greatly saved, the construction cycle is shortened and the water retaining quality is improved because the reinforced concrete pile and the plain concrete pile are matched for use; based on the occlusion effect of the cambered surfaces of the concrete, good occlusion and water-stopping effects between new and old concrete surfaces are achieved, and the construction quality is easy to control; and in addition, the application range is wide, different drilling machines can be used for forming pores in different water-bearing strata, and the predetermined water-stopping effect can be achieved as long as the pore forming quality meets the requirements of the specification.

Description

technical field [0001] The invention relates to a construction technique of a concrete template water-stop occlusal pile, which is used to form a water-stop curtain, and achieves the effects of water-stop and water-retaining through the occlusion of reinforced concrete piles and plain concrete piles. Background technique [0002] As the height of the building continues to increase, the depth of the foundation of the building will also continue to deepen. However, the buried groundwater in many areas is relatively shallow, and as the country pays more and more attention to environmental protection, the original traditional construction precipitation can no longer meet the construction requirements. In order to carry out the foundation pit construction where the buried depth of the foundation is greater than the groundwater table, various water-stop curtain technologies have emerged. [0003] The deep foundation pit support project with shallow groundwater burial mainly adopt...

Problems solved by technology

[0030] The purpose of the present invention is to provide a concrete template water-stop occlusal pile construction technology to solve the complex construction process and high construction cost of the existing pile grinding machine occlusal piles and underground diaphragm walls; It is also necessary to control other processes such as ultra-retarding concrete. The construction quality of jet grouting piles is difficult to guarantee in complex strata; and the underground diaphragm wall is usually designed synchronously with the basement structure, while jet grouting piles are greatly affected by soil quality. sexual constraints
