Problems solved by technology

For projects with a long construction period of the main structure, the cost of precipitation will be greatly increased, and the cost will increase accordingly; moreover, for places with a large temperature difference between day and night in the vast northern region, the foundation project will be exposed to the natural environment for a long time, which will cause extreme external walls of the foundation. It is easy to produce expansion and contraction cracks, and at the same time, the soil cannot be backfilled immediately after the foundation is completed, which has certain safety hazards for the deep foundation pit project; in addition, if the earthwork of the foundation pit is not backfilled in time, it will affect the development of subsequent processes and seriously affect the progress and construction period

Embodiment 1

[0036] 1. Concrete floor and exterior wall post-pouring belt to prevent water range

[0037] The scope of preventing water in advance for the foundation floor and the post-pouring belt of the outer wall should be applicable to the foundation floor of all buildings. The post-casting belt of the outer wall is especially suitable for high-rise buildings whose foundation is below the groundwater level, and can also be used for buildings with a long construction period of the main body The post-pouring tape project is also applicable to foundation projects that require post-pouring tape but the foundation cannot be exposed to the natural environment for a long time and needs to be backfilled immediately. In addition, it is also suitable for narrow construction sites or very urgent construction periods. Rapid construction of masonry and intercrossing between types of work within a short period of time.

Abstract

The invention discloses a method for conducting waterproof treatment on a foundation and a post-cast strip in advance. The method is characterized by comprising the following steps of concrete cushionlayer and leveling layer operation, additional coiled material and clearance laying waterproof coiled material operation, external attaching type rubber water stop strip operation, cement mortar protection layer operation, additional plate strip and cement mortar leveling layer operation, waterproof layer operation and protection layer operation.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for waterproofing foundations and post-pouring belts in advance. Background technique [0002] The bottom plate of the building foundation and the post-cast belt are the parts that are prone to leakage, and the post-cast belt is widely installed in the project, mainly to not affect the follow-up process, to ensure that the structure does not leave quality hidden dangers and to reduce the project cost. Precautions for preventing water stop in advance on the base plate and the post-cast belt of the external wall are also technical measures to make the project progress smoothly. The use of post-cast belts can be divided into subsidence post-cast belts and telescopic post-cast belts. [0003] For buildings with large building height differences and uneven structural distribution, in order to prevent the uneven settlement of the structure from causing cracks ...
