Description

Mattress drainage system

Technical Field

The utility model relates to a technical field of building engineering construction, concretely relates to bed course drainage system.

Background

Along with the urbanization development, the high-rise building rises rapidly, and the main height of the building and the depth of a cushion layer are in a proportional relation to a certain extent, so that the earth backfilling of the building cannot be ignored in the whole engineering construction process, and the collapse phenomenon around the building can be avoided only by paying attention to the earth backfilling condition. However, in the construction process, due to the influence of weather, the water accumulation of the cushion layer is easily caused in rainstorm weather, so that the cushion layer cannot be constructed, and the construction progress is seriously influenced; even if drainage measures are taken, if the drainage measures are not well taken, the drainage effect is still influenced, and the construction quality problem often occurs in the later stage.

The traditional backfill cushion layer drainage mode is only to simply introduce a drainage pipe to the bottom of a pit and drain accumulated water through a water suction pump, but the method is long in time consumption and low in efficiency; if the accumulated water can not be drained for a long time, the influence on underground buildings can be caused, and the use function of the basement is seriously influenced.

The patent with application number 201220212055.5 discloses "a foundation ditch drainage system", through set up the drain pump in the foundation ditch, is connected drain pump and drain pipe, utilizes the water pump to draw water, discharges water. The main focus is on the inclined arrangement of the branch ditches, but the method is not suitable for the top plate of the basement, and the patent does not provide a specific method.

The patent with application number 201621390481.2 discloses "a foundation ditch drainage system", including foundation ditch collector pipe, foundation ditch drainage control switch and the inside sump pit of foundation ditch, detect the water level through foundation ditch level sensor, and then control water pump unit draws the inside ponding of foundation ditch. The content is that a water collecting pipe flow sensor is arranged in a water collecting pit by utilizing a foundation pit, and the sensor drives an electromagnetic control valve to further control a water pump to pump water. However, the technology cannot achieve real-time drainage, and accumulated water can be accumulated in the foundation pit.

The patent with the application number of 201320545942.9 discloses a 'foundation pit accumulated water removing device', which comprises an outer cylinder, an inner cylinder and a water pumping device, wherein accumulated water flows into the inner cylinder after being filtered through water filtering holes in the outer cylinder, and the water pumping device pumps water from the inner cylinder to be removed. The content is that the water flows into the inner cylinder after being filtered through the water filtering holes on the outer cylinder, and the water pumping device pumps water from the inner cylinder for discharge. However, the technology still needs a water pump for pumping, and cannot pump water in real time and has poor water pumping effect.
