Description
Technical Field
The invention belongs to the technical field of energy-saving and environment-friendly building construction, and particularly relates to a method for building a waterproof facility of an underground parking lot by using a tower crane.
Background
With the rapid development of economic construction in China, an overground parking lot cannot meet the use requirement, all high-rise residential building groups are provided with underground garages, and in the construction process of the residential building groups, the determination of the tower crane construction scheme is a key construction technology in the whole building construction, so that the safety, the cost and the construction period are directly influenced. The position of the tower crane foundation can only be located in an underground garage, and the construction difficulty is increased along with the position. At present, the tower crane foundation is set by adopting the following two methods in construction sites:
firstly, a tower crane foundation is arranged below a water-resistant plate and forms a whole with the water-resistant plate, the method is simple to arrange, but the tower crane foundation is often higher than the water-resistant plate and needs to lie down on a part of the tower crane foundation, the area forms a strong support area, the periphery of the area is easy to be sheared and damaged under the action of the reaction force of the foundation to form cracks from bottom to top, underground capillary water goes upwards along crack channels to cause leakage at the cracks and corrosion of reinforcing steel bars around the parts below the cracks to cause structural damage, and the leakage and the cracks cannot be fundamentally remedied;
and secondly, directly arranging the tower crane foundation in a water-resistant plate, and issuing a scheme by a design institute to enlarge the cross section area and the reinforcing bars of the tower crane foundation. According to the method, a post-cast strip is not needed to be arranged in a tower foundation area, but the concrete in the area is easily cracked by vibration load generated in the tower crane construction process, so that later-stage cracks and leakage phenomena are caused. The two methods can form cracking and leakage in the tower crane foundation area at the later stage, so that how to fundamentally solve the problem that the tower crane foundation area does not crack or leak to form a construction pain point, the cracking reason is that overlarge tensile stress or shearing damage occurs in concrete, the concrete is pulled to crack or cut, and the leakage is that the waterproof layer is pulled to crack and loses the waterproof function. The method radically solves the following problems by eliminating cracking and leakage from the source: 1) the counter force of the substrate is uniformly stressed, and stress concentration is not generated; 2) the vibration load can not generate tensile stress to the area when the tower crane is constructed; 3) the waterproof layer cannot be deactivated.
The prior patent CN201811635193.2 discloses an anti-cracking and anti-seepage construction method for arranging a tower crane foundation under an independent foundation of an underground garage, which comprises the following steps: positioning a tower foundation and excavating earthwork → constructing a tower crane foundation cushion layer and a brick mold → constructing reinforcing steel bars, embedded parts and concrete of the tower crane foundation → installing the tower crane → constructing a retaining brick wall → backfilling the outer side of the retaining brick wall → paving an extruded polystyrene board → reserving a water-resistant board and a cushion layer construction seam → casting the cushion layer concrete outside a post-cast area → constructing a foundation waterproof layer and waterproofing treatment of the post-cast area → reinforcing steel bars outside the post-cast area of the water-resistant board, constructing the concrete → demolishing the tower crane after construction → demolishing the retaining brick wall and backfilling → casting the cushion layer concrete of the post-cast area → constructing the waterproof layer of the post-cast area → lapping the reinforcing steel bars of the water-resistant board in the post-cast area. The quality problem that the later stage of the tower crane foundation part is easy to crack and leak is solved.
However, as the waterproof measures of the underground garage are increasingly implemented by adopting off-wall lining, after the ground foundation of the underground garage is treated, lining materials such as various waterproof coiled materials, reinforcing steel bars and the like need to be hoisted into the space of the underground garage, and the lining materials need to be moved into the space of the underground garage after the ground foundation is made, and the construction method needs to be dismantled before the ground foundation of the underground garage is made, so that the hoisting capacity of a tower crane cannot be utilized to the maximum extent, the operation cost of waterproof construction of the underground garage is increased, and material and force are wasted.
