Description

Basement bottom plate structure

Technical Field

The utility model relates to a building structure technical field specifically is a basement bottom plate structure.

Background

With the continuous progress of social economy, the population is more and more, the ground space is more and more urgent, so more and more buildings develop to the underground space. Along with the continuous deepening of the basement building to the underground, the anti-floating problem is gradually highlighted. In the construction stage of the basement, the traditional method is that a long-strip-shaped post-pouring strip is arranged on the basement floor, and the post-pouring strip is usually used on a non-closed movable bottom plate structure; and then in subsequent construction, after the building weight or other effective anti-floating measures on the upper part of the basement meet the design requirements, pouring concrete into the post-pouring belt and sealing, so that the basement meets the anti-floating requirements. However, when the underground supporting structure of the basement is an underground diaphragm wall and the diaphragm wall is also used as an outer wall of the basement, the whole basement is like a closed basin body in the construction stage, the basin body floats under the action of underground water pressure, a post-pouring belt cannot be used for a basement bottom plate of the basement, the problem of water drainage and anti-floating in the construction stage is particularly severe, and the development of the basement structure is hindered.

Through retrieval and discovery, the basement bottom plate structure with the water drainage holes is disclosed in a Chinese patent with an authorization publication number of CN204343342U, and sequentially comprises a C15 plain concrete cushion layer, a first waterproof layer and a reinforced concrete substrate from bottom to top, the basement bottom plate structure further comprises the water drainage holes formed in the substrate and a fast and easy closing net arranged on the inner side surface of the water drainage holes, the bottom ends of the water drainage holes penetrate through the first waterproof layer, the water drainage holes are multi-stage stepped holes with large top and small bottom, and grooves are formed in stepped planes on the lower sides of the stepped holes.

In the technical scheme, the drainage effect can be realized through the drainage holes in the multi-stage stepped hole shape, but more impurities and the like are inevitably accumulated in the drainage holes after the basement is used for a long time, and more impurities and the like can block the drainage holes to a certain degree, so that the drainage effect of the drainage holes is influenced, and the basement bottom plate is also subjected to the buoyancy of underground water.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a basement bottom plate structure aims at solving basement bottom plate among the prior art and sluices together more impurity etc. in the drainage hole after long-time the use, and more then can block up the drainage hole to a certain extent when impurity etc. more and more, has influenced the sluicing effect of drainage hole, still makes the basement bottom plate receive the problem of the last buoyancy of groundwater.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the basement bottom plate structure includes:

flood discharging pits are arranged at intervals before the basement bottom plate is constructed;

the drainage pipe is arranged in the flood discharge pit;

pouring a groove body arranged in a basement bottom plate;

a filter screen transversely arranged in the tank body;

a water outlet pipe communicated with the upper side inside the tank body and positioned at the upper part of the filter screen;

a first valve mounted on the water outlet pipe;

a trash discharge pipe communicated with the lower side of the interior of the tank body and positioned at the lower part of the filter screen;

a second valve installed on the impurity discharging pipe;

a guide pipe for connecting the lower side of the inside of the tank body with the water discharge pipe.

A primary filtering structure is arranged in the flood discharge pit, and the drain pipe extends into the primary filtering structure.

The primary filtering structure comprises a coarse sand filtering layer, a fine sand filtering layer and a cobble layer which are sequentially arranged in the flood discharge pit from outside to inside.

And a flood discharge pit supporting piece is arranged in the flood discharge pit.

Flood discharge pit support piece includes two at least fixed montants and two at least fixed horizontal poles that are used for connecting fixed montant.

And a waterproof layer is arranged on the inner wall of the groove body.

The drain pipe is a galvanized steel pipe.

The first valve and the second valve are both electric control valves.

The utility model has the advantages that: after groundwater water level rises, groundwater enters into the flood discharge pit, groundwater which continuously rises enters into the diversion pipe through the drainage pipe, groundwater is made to enter into the groove body, the first valve is opened and the second valve is closed at the moment, groundwater which continuously gushes in is finally discharged through the drainage pipe after passing through the filter screen, the pressure of the basement bottom plate is effectively relieved, and impurities and the like in the groundwater are intercepted by the filter screen due to the effect of the filter screen, the water is prevented from blocking the drainage pipe to influence the pressure relief effect of the basement bottom plate, and after the groundwater is used for a period of time, when more impurities and the like are intercepted by the filter screen at the lower side in the groove body, the first valve is closed at the moment and the second valve is opened, water impacts the impurities and the like at the lower side in the groove body and is discharged through the impurity discharge pipe, thereby realizing automatic slag discharge, avoiding the influence of accumulating excessive impurities and the like on the flood discharge, and also can make the utility model discloses long-time good operation can not cause the jam to the pipeline of impurity etc..
