[0005] Furthermore, a water-stop steel plate is provided on the wall sleeve, and the water-stop steel plate is placed inside the outer wall of the basement.

[0006] Furthermore, an additional steel plate is sleeved on the wall sleeve, and the additional steel plate is closely attached to the outer side of the row of supporting piles.

[0007] Furthermore, a waterproof roll is laid on the outer side of the additional steel plate.

[0008] Furthermore, the thickness of the crown beam is 400 mm.

[0009] Furthermore, the length and width of the waterstop steel plate are both 100 mm longer than the length and width of the reserved opening, and the thickness of the waterstop steel plate is 4 mm.

[0010] Furthermore, the length of the portion of the wall sleeve extending out of the basement outer wall is 1.2 m.

[0011] The beneficial effects of the present invention are as follows: the design structure of the present invention is simple, and the wall sleeves in the single-side formwork area can be processed more easily. Holes for the wall sleeves are reserved at the support structure position, so that the outward-extending wall sleeves can be directly extended at the support structure position, and there is no need to perform secondary chiseling on the support structure when the external sleeves are connected; steel plates are added at the group wall sleeve positions, and waterproof products can be directly constructed on the steel plates. The waterproof materials and steel plates can be effectively combined to reduce the hidden dangers of leakage quality of the exterior wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] like Figures 1 to 3 As shown, a waterproof wall-penetrating pipe water-stopping device for a basement with single-sided formwork external wall comprises: a basement external wall 1, the basement external wall 1 being arranged on a cushion layer 2, a support structure being provided on the inner side of the basement external wall 1, the support structure comprising a row of support piles 3 and two rows of support piles 4, a waterproof leveling layer 5 being provided between the row of support piles 3 and the basement external wall 1, a reserved opening 6 being provided on the row of support piles 3, a crown beam 7 being provided around the reserved opening 6, the top of the crown beam 7 being erected on the top of the row of support piles 3 and the two rows of support piles 4, a wall-penetrating pipe 8 being passed through the reserved opening 6, the wall-penetrating pipe 8 being formed of a plurality of pipes in a rectangular array, the outer end of the wall-penetrating pipe 8 passing through the basement external wall 1. The reserved opening 6 is provided on the support structure according to the specific position of the wall-penetrating pipe 8, and the optimized design reduces the need for secondary chiseling of the support structure. A crown beam 7 of a concrete structure is arranged around the reserved opening 6 to increase the peripheral strength of the supporting structure hole.
