Abstract
The invention relates to a containment enclosed structure for a rock connection section of a whirling pool. The whirling pool comprises a bottom sealed reinforced concrete layer located at the bottom on a rock layer and an upper structure, underground diaphragm walls are arranged on the outer sides on the periphery of the whirling pool and located on the rock layer, gaps are reserved between the underground diaphragm walls and the rock layer, and the enclosed structure comprises a group of polyethylene (PE) water falling well point pipes, a total water collecting pipe, standby valves and light well point water-pumping sets, wherein the PE water falling well point pipes are distributed around the whirling pool along the diameter direction and inserted into the whirling pool from the positions between the underground diaphragm walls and the rock layer; the total water collecting pipe surrounds the whirling pool and is arranged between the underground diaphragm walls and the rock layer, and the PE water falling well point pipes are communicated with the total water collecting pipe; one ends of the PE water falling well point pipes, which are inserted into the whirling pool, are provided with standby valves respectively; and each of the PE water falling well point pipes is connected with one light well point water-pumping set through a corresponding connection pipe. According to the containment enclosed structure, the piping phenomenon of a foundation pit of the whirling pool can be effectively eradicated.
Description
Technical field
The present invention relates to Whirlwind tank, relate in particular to the space enclosing structure that a kind of Whirlwind tank connects the rock section.
Background technology
Whirlwind tank has become the indispensable facility of the newly-built hot rolling project of smelter gradually.The large-scale metallurgical enterprise in China riverine and coastal area generally all sets up near water.At present, the Whirlwind tank degree of depth is in depth descended more than 30 meter, and is very complicated for regional near water underground structure.Take In Middle And Lower Reaches of Changjiang River as example, its soil layer is drift sand formation, silt clay layer, burning into sand argillic horizon, andesite layer, the absolute altitude of andesite layer and burning into sand soil layer binding site is 29 ~ 31 meters not to be waited, the Whirlwind tank continuous wall trench underground degree of depth can only reach this place, because the bottom has the sediment of some behind the continuous wall trench underground, the absolute altitude of andesite layer is uneven, so can have the space at this position diaphragm wall and andesite joint portion, excavation of foundation pit behind this position because Piping phenomenon can appear in the pressure-acting of outside muddy water.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides a kind of Whirlwind tank to connect the enclosed construction of going along with sb. to guard him of rock section.The present invention can effectively stop the Piping phenomenon of Whirlwind tank foundation ditch.
For addressing the above problem, a kind of Whirlwind tank connects the enclosed construction of going along with sb. to guard him of rock section, described Whirlwind tank comprises back cover reinforced concrete floor and the superstructure of the bottom that is positioned on the lithosphere, the outside and be positioned at lithosphere and be provided with diaphragm wall around the Whirlwind tank, gapped between this diaphragm wall and the lithosphere, described enclosed construction comprises:
One group of PE precipitation well point pipe is arranged along diametric(al) around Whirlwind tank, and from inserting between diaphragm wall and the lithosphere in the Whirlwind tank;
Water header, it around Whirlwind tank and be arranged on diaphragm wall and lithosphere between, described PE precipitation well point pipe and this water header are communicated with;
Standby valve, the end that described PE precipitation well point pipe inserts in the Whirlwind tank is provided with a standby valve separately;
The light well point water-pumping group, each PE precipitation well point pipe connects a light well point water-pumping group by corresponding tube connector.
Described Whirlwind tank connects the enclosed construction of going along with sb. to guard him of rock section, the described standby valve valve that also is in the milk as a supplement.
Described Whirlwind tank connects the enclosed construction of going along with sb. to guard him of rock section, and it also comprises the falsework that is arranged on superstructure, and the setting of described Application of light well point precipitation unit thereon.
Well point system of the present invention can be extracted the underground water of going along with sb. to guard him behind the defective slit out, makes its soil solidifying, does not affect to frighten the operation construction.Standby valve slip casting is set, can plays diversion and slip casting double effects.Easy construction, easy operating.The present invention can effectively stop the Piping phenomenon of Whirlwind tank foundation ditch.
