Problems solved by technology

However, when there is a sudden heavy rain or a large amount of water accumulates unexpectedly, the water level in the ground may rise, causing buoyancy to the pit and causing damage to the building.

Embodiment

[0015] Example: The method for preventing the foundation of a pit-type building from floating in the present invention is as figure 1 Shown. During the specific construction, the sump 2 can be set up according to the requirements of other professions, and then the sump 2 can be set at the four corners below the bottom plane 16 of the pit 1, if the sump 2 required by the present invention It overlaps with the sump 2 set up by other professional requirements, and the two can be used in combination. The sump 2 can be molded with the pit at one time. An overflow 3 is set at the bottom of each sump 2, and a valve 7 is provided on the overflow 3. When the local water level 15 is higher than the overflow 3 to generate buoyancy on the pit 1, open the valve 7 on the overflow 3 to allow The groundwater overflows into the sump 2, and then the water in the sump 2 is pumped out with a sewage pump or a water pump of the sewage system in the building to reduce the groundwater level 15 and elimi...

Abstract

The invention discloses a method and a structure for preventing a pit-type building foundation floating. The method comprises the following steps that: a water collecting pit is arranged under the bottom plane of the pit; the bottom part of the water collecting pit is provided with a water overflow outlet; the water overflow outlet is provided with a valve; when the water table is higher than the flotage generated by the water overflow outlet to the pit, the valve of the water overflow outlet is opened, groundwater overflows into the water collecting pit, and then a water pump pumps out water in the water collecting pit so as to reduce the water table, eliminate or reduce the flotage generated by the groundwater to the pit, and prevent damaging the building because of the pit floating. The method and the structure adopt a novel anti-floating principle to eliminate the flotage generated by the water to the pit by water dredge and drainage, and are suitable for the ground conditions of various ground layers under the building. The method and the structure can prevent the floatation of the ground water to the pit damaging the pit or the building during heavy rains or accident great water accumulation.

Description

Technical field [0001] The invention relates to a method and structure for preventing the foundation of a pit-type building from floating, and belongs to the technical field of building foundations. Background technique [0002] In engineering construction, you must first lay a foundation underground, and then build a house on the foundation. The usual foundation is like a large ship cast from reinforced concrete. It is called a pit in engineering. The pit must bear the building on the one hand. The downward pressure load, on the other hand, has to bear the buoyancy of the groundwater on the building. If the pit sinks or rises, and when the settlement or floating speed of each part is inconsistent, the pit will crack or even be destroyed. Then the buildings above the pit will also be destroyed at the same time. For the consideration of anti-sinking and anti-floating, pile foundation is usually adopted. The specific method is: cast at the bottom of the pit and connect the reinforc...
