Concrete basement structure with/without bonding prestress and its construction method

Abstract

The invention discloses a bonded-unbonded pre-stress concrete basement structure and a corresponding construction method thereof. The construction method includes the floor-slab construction involving the steps of: separating a pile body from a soleplate, arranging a plastic plate sliding layer, applying the pre-stress; and carrying out waterproof treatment and integrating the pile body with the soleplate. The outer wall construction involving the steps of: arranging a sliding layer between the outer wall and the soleplate or the floor-slab; applying the pre-stress; carrying out the anti-corrosion treatment to the anchoring tools; carrying out the pressure grouting for the pre-embedded pipes with the bonded pre-stress and grouting the big or small pedestal foot of the outer wall of the basement after the pre-stress is applied to the outer wall of the basement. The basement structure is constructed according to the construction method and has the advantages that the load-carrying capability is better; the leakage can be avoided; the durability is strong and the earthquake resistance is good; in addition, the basement structure eliminates the temperature expansion joints, post-cast strips and expansion reinforced strips, completely avoids the leakage risk caused by the rubber waterproof strip and the like and the trouble caused by the management and maintenance, thus overcoming the various defects of the existing basement.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a basement structure of prestressed concrete with or without bonding and a construction method thereof. Background technique [0002] With the rapid development of my country's economy, more and more building basements and underground parking lots are being built. According to my country's current engineering structure design method, many problems have been exposed in use. For example, according to my country's current "Code for Design of Concrete Structures" GB50010-2002, it is required to set up an expansion joint every 30-55m for different structures under indoor or soil conditions. For a building with a large plane size, it must be divided into many blocks, these blocks are completely separated, and the middle is connected with a rubber waterstop for waterproofing, such as Figure 1b As shown in the traditional basement expansion joint method, the temperat...

Problems solved by technology

However, in the basements constructed by the above method, many basements have leakage problems, and the leakage problems of some basements cannot be solved, causing the basements to be soaked in water for a long time
