Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses plugging structure behind cable pit entry double-deck flange. Referring to fig. 1, the plugging structure behind cable pit entry double-deck flange includes that the symmetry sets up two stagnant water boards 1 in 2 thickness direction both sides of wall body and all covers the perforation 21's of wall body 2 open-ended, all be the matrix form on two stagnant water boards 1 and seted up a plurality of through-holes, the through-hole along stagnant water board 1 runs through on wall body 2 and is provided with a plurality of wall-penetrating pipelines 3, the periphery side of a plurality of wall-penetrating pipelines 3 all with the sealed surface welding of stagnant water board 1, a plurality of wall-penetrating pipelines 3 lie in outdoor one end and outwards extend and its week side and lie in and be provided with outer envelope 4 between outdoor stagnant water board 1, outer envelope 4 can be made for materials such as concrete or fire prevention daub, be provided with the connecting piece that is used for connecting stagnant water board 1 and wall body 2 on the stagnant water board 1. When carrying out perforation 21's shutoff, two sealing plate 1 form about shutoff perforation 21's double-deck flange structure on wall body 2, through pouring the grout material between two sealing plate 1 in perforation 21 to form firm grout blanket, thereby form firm shutoff structure on wall body 2 jointly, make wall body 2 difficult the appearance of breakage in perforation 21 department.

Referring to fig. 2, in order to make the outdoor ground water not easily seep into the room through the through hole 21 between the water stop plate 1 and the wall body 2, an externally attached water stop 6 is arranged between the water stop plate 1 and the wall body 2 at the outdoor side; one end of the externally-attached water stop belt 6 is annularly bonded on the inner peripheral wall of the through hole 21 along the inner peripheral wall of the through hole 21, the other end of the externally-attached water stop belt 6 is bent to extend to the outer side of the wall body 2 and is bonded with the side face of the outdoor water stop plate 1, and the water seepage resistance of the plugging structure is greatly improved through the externally-attached water stop belt 6.

Referring to fig. 1, in order to stably mount the water stop plate 1 on the wall 2, in this embodiment, the connecting member is a connecting angle 51, and two connecting angle 51 are disposed on each side of the water stop plate 1; a right-angle side of each connecting angle iron 51 is fixedly connected with the wall body 2, and the other right-angle side is welded with the water stop plate 1. In other embodiments, the number of the connection angle irons 51 is set to four in order to save construction costs. Two of the connecting angle irons 51 are arranged at two bottoms of the water stop plate 1, and the other two connecting angle irons 51 are symmetrically arranged on two side walls of the water stop plate 1. When the angle iron 51 is fixedly connected with the wall 2, a worker welds a right-angle edge of the angle iron 51 on the reinforcing steel bars by chiseling the reinforcing steel bars in the wall 2 on the surface of the wall 2, or fixes the right-angle edge of the angle iron 51 on the wall 2 through expansion bolts.

Referring to fig. 3, in another embodiment, the connecting member is a pull rod 52, the pull rod 52 penetrates through the two water stop plates 1, nuts 53 are screwed on both ends of the pull rod 52 penetrating through the water stop plates 1, and a water stop washer 54 is sleeved on the pull rod 52 between each nut 53 and the adjacent water stop plate 1. When the water-stop plate is used, a worker can clamp and fix the two water-stop plates 1 on the wall body 2 by screwing the two nuts 53, and then the two water-stop plates 1 can be installed and fixed; and the screwed nut 53 presses the water stop washer 54 at the joint gap between the water stop plate 1 and the pull rod 52, so that no water seepage point exists on the surface of the water stop plate 1.

Referring to fig. 1 and 2, in order to facilitate the filling of the grouting material in the through hole 21 by the worker, the grouting material forms a stable grouting layer in the through hole 21 between the two water stop plates 1; two pouring openings 11 are arranged at the upper end of the water stop plate 1 on one side close to the indoor space at intervals along the horizontal direction (in other embodiments, the number of the pouring openings 11 can also be three or four, etc.), and the edge of the inner top wall of the perforation 21 is provided with a notch communicated with the two pouring openings 11 one by one. The operator fills the grout through one of the pouring openings 11, and the other pouring opening 11 is used to keep the air pressure balance between the inner cavity of the through hole 21 and the outdoor environment, so as to conveniently fill the grout in the through hole 21. In other embodiments, the worker pre-inserts a plurality of reinforcing bars into the through hole 21 so that the grouting material forms a stable reinforced grouting layer in the through hole 21.

Referring to fig. 2, because the grout material of pouring into in the perforation 21 is cement mortar often, in order to reduce the condition emergence that the new and old concrete interface department that cast-in-place cement mortar leads to because of the shrink appears the gap infiltration, perforation 21 internal perisporium inlays and is equipped with water-swelling rubber sealing strip 8, when the staff pours the grout material in perforation 21, blocks up gap water through water-swelling rubber sealing strip 8 water-swelling, with play grout layer and perforation 21 inner wall between waterproof impervious effect.

The implementation principle of plugging structure behind the double-deck flange of cable pit entry of this application embodiment is: the worker firstly removes sundries on the inner wall of the through hole 21 and then fixes the water-swelling rubber water stop strip 8 on the inner wall of the through hole 21; then, the worker attaches a water stop plate 1 to an opening at one end of the through hole 21 facing the outside through an externally attached water stop band 6, and fixes the water stop plate 1 to the wall body 2 through a connecting piece. The worker then fixes another water stop plate 1 to the indoor side of the wall 2 by means of the connector and covers another opening of the perforation 21 with another water stop plate 1.

Then the staff will wear the wall pipeline 3 and run through the wall body 2 along the through-hole on the stagnant water board 1 to with the periphery side of wearing the wall pipeline 3 and the surface seal welding of stagnant water board 1, then be provided with outer envelope 4 between the outdoor one end week side of locating in a plurality of wearing the wall pipeline 3 and the stagnant water board 1 that is located outdoors, in order to form the stagnant water shutoff. Then, grouting material is poured into the through hole 21 through the pouring opening of the water stop plates 1, so that the grouting material forms a stable grouting layer between the two water stop plates 1 in the through hole 21. Then, the worker inserts the outdoor cable into the room along the wall-penetrating pipe 3, and the waterproof sealing material is filled between the outdoor cable and the inner wall of the wall-penetrating pipe 3, so that the cable-entering operation can be completed.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
