Used as the further improvement to above-mentioned embodiment, the sealing outer shroud and sealing internal ring are made using steel plate,
And fixed by one side full weld and casing pipe, weld bead height is not less than 5mm.
The present invention solves another technical scheme for being adopted of its technical problem and is to provide a kind of to prevent letting out for basement floating-up
The using method of jacket pipe, comprises the following steps：
(1) after cushion construction, concrete floor construction is carried out, casing pipe is vertically fixed in reinforcing bar process of binding
On bed course；
(2) inside of casing pipe is filled using implant；
(3) concreting is carried out on bed course form concrete floor；
(4) retaining sleeve body is unobstructed, carries out basement roof and the construction of top earthing；
(5) earthing construction is finished, and after anti-floating condition is met, the moisture inside casing pipe is blotted, is sealed with grouting material
Close.
As one kind of the invention preferred embodiment, the sluicing sleeve pipe is arranged at the middle part of basement.
As the further improvement to above-mentioned embodiment, the sluicing sleeve pipe be arranged in gutter or near.
Beneficial effect
In the present invention, sluicing sleeve pipe is embedded in the concrete floor of basement post-pouring zone, is not covered in basement roof
Play sluicing effect before soil, closed with grouting material after earthing, inside and outside due to casing pipe is equipped with seal ring, can avoid
Seepage is produced after closure, fabrication and installation are simple, pre-buried closure is convenient, and pressure release effect is good, prevents basement floating-up effect
Substantially.
