Description

Pressure relief and drainage device for continuous wall of underground floor of building

The invention relates to a pressure relief and drainage device, in particular to a pressure relief and drainage device applied to the continuous wall of the underground floor of a building.

According to, in the construction method of the underground floor of the building building at present, the continuous wall is first built around the building area, and then many rows of temporary steel columns are inserted in the area, and then the earthwork is excavated layer by layer, and the layers are combined successively. Temporary steel beams and braces, and then excavate the earthwork at the bottom until the raft base and sewage tanks are cast, and then complete the floor slabs and concrete columns of the underground floors from bottom to top.

This kind of known building building must be equipped with pipelines inside the raft base and outside the diaphragm wall, so that the groundwater outside the basement diaphragm wall can be diverted into the sewage tank inside the raft base, and then cooperate with the control pumping system to discharge. However, as the building ages, the connecting pipes inside and outside the raft base will gradually accumulate and block. Therefore, there is often too much groundwater outside the underground floor surrounding the continuous wall, and the groundwater outside the continuous wall cannot be drained for a long time, resulting in the continuous wall being damaged. Long-term soaking in water will cause wall cancer or traces of water seepage. Moreover, there are more than tens of thousands of felt and unsensed earthquakes in Taiwan every year, that is, groundwater shock waves frequently hit the continuous wall, so the concrete of the continuous wall is prone to oxidation and decomposition after many years, forming a seepage waterway, causing groundwater to seep from the continuous wall inward and out of the wall. .

When the water seepage problem occurs in the continuous wall, most of the current high-pressure injection methods are used to inject injections into the cracks or water seepage to achieve the anti-leakage effect. However, the groundwater outside the continuous wall is abundant, and if there is no pressure relief and drainage, the leakage will never be stopped. As a result, after the continuous wall has been eroded by groundwater for a long time, water seeps in from other walls of the continuous wall. Even if the thickness of the continuous wall reaches 1 meter, under the continuous erosion and penetration of external groundwater and water pressure, if groundwater seeps into the steel bars inside the continuous wall, the steel bars will be oxidized and rusty water will flow out. Therefore, how to solve the above-mentioned problems is the subject that relevant industry players in this industry are eager to study.

The main purpose of the present invention is to pass the groundwater outside the continuous wall sequentially through the conduction pipe, the drainage pipe and the discharge pipe, so that the groundwater flows down through the discharge pipe into the sewage tank inside the raft foundation of the underground floor, so as to achieve the effect of decompression and drainage of groundwater. To completely solve the water seepage problem of the continuous wall around the underground floor.
