Problems solved by technology

At present, there are two most commonly used construction schemes: the first method: the foundation of the tower crane is below the floor of the underground garage, and no construction joints are left when pouring the floor. Pouring in concrete, this method has three disadvantages: first: waste of standard sections, cross beams, high cost
Second: long-term groundwater soaking, the standard section of the buried tower crane is corroded, and the bottom plate seeps
Third: when pouring concrete on the bottom plate, due to the continuous work of the tower crane construction, dynamic loads are formed on the reinforced concrete bottom plate structure, causing disturbances and adverse effects on the underground structure. cause water seepage
However, this method has one of the biggest shortcomings, and it has not been able to completely solve the problem so far: that is, leakage
At present, there is a large amount of water seepage risk in the tower crane foundation part of most basement floors. If effective control is not carried out in time, it may affect the construction period and construction quality of the construction project.

Abstract

The invention provides an anti-seepage structure and construction method of a tower crane foundation in a basement floor of a building, comprising a reinforced concrete floor, a waterproof protective layer, a tower crane bearing base, a tower crane foundation, and a waterproof coiled material on the bottom side of a brick membrane wall, The main support structure and reinforcement components are respectively arranged on both sides of the tower crane foundation above the basement floor; the construction method includes the following steps: step S1: pouring a reinforced concrete floor, laying a waterproof protective layer and pouring into a tower crane bearing base; step S2: laying brick tires Membrane and laying of waterproof membrane; step S3: pouring the basement floor, steel mesh and waterproof steel plate; step S4: fixing the main support structure and reinforcement components. The beneficial effects of the present invention are: the main support structure and reinforcement components in the present invention are used to support and reinforce the foundation of the tower crane, preventing the foundation of the tower crane from inclining and forming cracks at the connection with the surrounding concrete due to groundwater penetration, and more water seeps into the cracks middle.

Description

technical field [0001] The invention relates to the technical field of waterproof structures for building foundations, in particular to an anti-seepage structure and a construction method for a tower crane foundation in a basement floor of a building. Background technique [0002] In recent years, due to the boom in the property market, residential quarters have developed towards higher and deeper ends. For underground garages, construction sites with large civil air defense projects, and the limited range of tower crane work, it is determined that the foundation of the tower crane can only be set in the underground garage. Within the scope, how to correctly choose a reasonable tower crane foundation construction plan is extremely important to prevent the basement floor from seepage at the tower crane foundation position. At present, there are two most commonly used construction schemes: the first method: the tower crane foundation is below the floor of the underground garag...
