Description

Foundation pit drainage system

Technical Field

The utility model relates to a construction technical field, especially a foundation ditch drainage system.

Background

The foundation pit is a soil pit excavated at the design position of the foundation according to the elevation of the foundation and the plane size of the foundation. Before excavation, an excavation scheme is determined according to geological and hydrological data and the conditions of buildings nearby the site, and waterproof drainage work is performed. The person who is not excavated can use the method of putting the side slope to stabilize the earth slope, and the size of the slope is determined according to the relevant construction regulations. When a deeper foundation pit and a building adjacent to the deeper foundation pit are excavated, a foundation pit wall supporting method, a concrete-sprayed wall protecting method and a large foundation pit are used, and even an underground continuous wall and a columnar column type bored pile are used for interlocking, so that an outer soil layer is prevented from collapsing; for those who have no influence on nearby buildings, the underground water level can be reduced by a well point method, and slope releasing open cut is adopted; in cold regions, natural cold freezing method can be adopted for excavation and the like.

The existing foundation pit drainage system is incomplete in data monitoring, low in drainage efficiency, prone to causing large-area water accumulation in a foundation pit, capable of delaying construction period, not convenient for improvement of working efficiency and prone to causing safety accidents such as collapse, and therefore the foundation pit drainage system is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a foundation ditch drainage system, it is low to solve traditional foundation ditch drainage efficiency, and the muddy water problem can't be filtered in the drainage, this application is through twice filtration for water pumping device extracts the water purification after filtering, avoids silt and stone too much, causes the damage to pumping equipment.

The purpose of the utility model is realized through the following technical scheme:

a foundation pit drainage system comprises a foundation pit, wherein drainage ditches are arranged around the foundation pit, filter plates are uniformly paved above the drainage ditches, filter boxes are also arranged in the drainage ditches, and the filter boxes are connected with a water pumping device through water pumping pipelines; the side surfaces of the periphery of the filtering box body are respectively provided with a filtering net, the bottom of the filtering box body is of a fully-closed structure, the top of the filtering box body is provided with an opening, and a water pumping pipeline extends into the filtering box body from the opening; the end of the pumping pipeline is provided with a limiting disc, and the radius of the limiting disc is larger than that of the opening.

Because the water in traditional deep basal pit is mostly dirty, contains a large amount of silt and stones, at the in-process that draws water, causes the damage to pumping device easily. This application is through digging the escape canal around the foundation ditch, through the water logging with in the foundation ditch in pouring into the escape canal, draws water in by the escape canal again, and whole process is through twice filtration, can avoid a large amount of silt and stone to the threat of pumping equipment.

When the water in the foundation pit does not immerse the drainage ditch any more, part is dug away to the dykes and dams between foundation pit and the drainage ditch, lets the water in the foundation pit continue to flow to the drainage ditch.

Furthermore, a plurality of filtering box bodies are uniformly distributed in the drainage ditch, and each filtering box body is connected with a water pumping device through a water pumping pipeline.

Furthermore, a water level display rod is arranged in the drainage ditch.

Further, still be equipped with the water sample in the escape canal and gather the pole, the bottom of water sample collection pole is equipped with the water sample and gathers the bottle, and the top of water sample collection pole is equipped with the handle.

The utility model has the advantages that:

the utility model provides a traditional foundation ditch drainage efficiency is low, and muddy water problem can't be filtered in the drainage, and this application is through twice filtration for water pumping device extracts the water purification after filtering, avoids silt and stone too much, causes the damage to pumping equipment.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

A foundation pit drainage system is shown in figure 1 and comprises a foundation pit 10, a drainage ditch 11 is arranged around the foundation pit 10, filter plates 15 are uniformly paved above the drainage ditch 11, a filter box body 14 is also arranged in the drainage ditch 11, and the filter box body 14 is connected with a water pumping device 13 through a water pumping pipeline 12; a filter screen 16 is mounted on the peripheral side surface of the filter box body 14, the bottom of the filter box body 14 is of a fully-closed structure, an opening 17 is formed in the top of the filter box body 14, and the water pumping pipeline 12 extends into the filter box body 14 from the opening 17; the end of the pumping pipeline 12 is provided with a limiting disc, and the radius of the limiting disc is larger than that of the opening.

In a preferred embodiment, a plurality of filter boxes 14 are uniformly arranged in the drainage ditch 11, each filter box 14 is connected with a water pumping device 13 through a water pumping pipeline 12, a plurality of water pumping devices 13 work simultaneously, water in the drainage holes 11 can be rapidly pumped out,

as a preferred embodiment, a water level display rod is provided in the drainage ditch 11, and is used for observing whether the water level in the drainage ditch 11 is lower than a preset water level, so that the dam can be conveniently excavated and the water in the foundation pit can flow in.

As the preferred embodiment, still be equipped with the water sample in the escape canal 11 and gather the pole, the bottom of water sample collection pole is equipped with the water sample collection bottle, and the top of water sample collection pole is equipped with the handle.
