Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
as fig. 1, do the utility model discloses a waterproof construction for underground pipe gallery, including ground basis 1, ground basis 1's both sides are provided with the ascending interior wall 11 of perpendicular ground basis 1. As shown in fig. 2, a waterproof rock wool felt layer 2 is laid on the ground foundation 1 and the inner wall 11, and the waterproof rock wool felt layer 2 has not only waterproof performance, but also certain heat preservation effect and high temperature resistance.
Referring to fig. 2, a sealant layer 3 is coated between the waterproof rock wool felt layer 2 and the ground foundation 1 and the inner wall 11, and the waterproof rock wool felt layer 2 is fixed to the ground foundation 1 and the inner wall 11 by the sealant layer 3. Inside waterproof rock wool carpet veneer 2 got into the underground pipe gallery through waterproof rock wool carpet veneer 2 the outside water of prevention underground pipe gallery that waterproof rock wool carpet veneer 2 can be preliminary.
The one side that waterproof rock wool carpet veneer 2 is close to ground basis 1 and interior wall 11 is the ripple shape, and the ripple shape has increased waterproof rock wool carpet veneer 2 and sealant 3's area of contact, makes the waterproof rock wool carpet veneer 2 more fastening pass through sealant 3 and ground basis 1 and interior wall 11 fixed.
As shown in figure 2, a right-angle steel plate 4 is fixed on one surface of the waterproof rock wool felt layer 2, which is far away from the ground foundation 1 and the inner wall 11, and the right-angle steel plate 4 is positioned at the joint of the ground foundation 1 and the inner wall 11. The right-angle steel plate 4 has an effect of further waterproofing the joint of the ground foundation 1 and the inner wall 11. The both ends fixedly connected with waterproof material layer 5 of right angle steel sheet 4, waterproof material layer 5 is fixed respectively on waterproof rock wool carpet veneer 2, and waterproof material layer 5 plays and makes interior wall 11 and ground basis 1 further waterproof effect.
The one side that waterproof rock wool felt layer 2 was kept away from to right angle steel sheet 4 is fixed with elastic water stop 6, and the one side corner that elastic water stop 6 kept away from right angle steel sheet 4 is the fillet. And first waterproof rolls 7 are fixed at two ends of the elastic water stop belt 6, and the first waterproof rolls 7 are fixed on the waterproof material layer 5.
As shown in fig. 2, in order to strengthen the connection between the elastic water stop 6 and the first waterproof roll 7 and reduce the possibility that water flows into the underground pipe gallery from the gap between the elastic water stop 6 and the first waterproof roll 7, a sealant layer 3 is coated between the elastic water stop 6 and the first waterproof roll 7. The one side that sealing adhesive layer 3 kept away from waterproof material layer 5 is fixed with additional waterproofing membrane 8, and additional waterproofing membrane 8 shelters from sealing adhesive layer 3 between elastic water stop 6 and the first waterproof membrane 7 completely.
One side of the elastic water stop belt 6 away from the right-angle steel plate 4 is fixedly connected with a second waterproof coiled material 71, and the second waterproof coiled material 71 is easy to crack at the corners of the ground foundation 1 and the inner wall 11, so that the waterproof effect of the second waterproof coiled material 71 is influenced. To solve this problem, the second waterproof roll 71 is divided into two parts, and the two parts of the second waterproof roll 71 are connected with each other by the sealant layer 3, wherein the sealant layer 3 is located at the round corner of the elastic water stop 6. One end of the second waterproof roll 71 on the elastic water stop 6 is fixedly connected with the additional waterproof roll 8.
As shown in fig. 2, in order to enhance the sealing property of the connection between the second waterproofing membrane 71 and the additional waterproofing membrane 8, the two are fixedly connected by the sealant layer 3.
The implementation principle of the embodiment is as follows: on one hand, the waterproof rock wool felt layer 2, the right-angle steel plate 4, the elastic water stop belt 6 and the second waterproof coiled material 71 are sequentially arranged at the joint of the ground foundation 1 and the inner wall 11, so that multiple fortification is realized, and the waterproof performance of the joint of the ground foundation 1 and the inner wall 11 is improved; second waterproofing membrane 71 easily produces the fracture in the corner of elastic water stop 6, therefore the one side that elastic water stop 6 keeps away from right-angle steel plate 4 is fixed with a pair of second waterproofing membrane 71, connects through sealant layer 3 between a pair of second waterproofing membrane 71, and sealant layer 3 is located the corner of elastic water stop 6.
On the other hand, the waterproof rock wool felt layer 2, the waterproof material layer 5, the first waterproof coiled material 7 and the waterproof coating 9 are sequentially arranged on the ground foundation 1 and the inner wall 11 respectively, so that multiple fortifications are realized, and the waterproof performance of the ground foundation 1 and the inner wall 11 is improved.
Example two:
referring to fig. 3, a waterproof structure for an underground pipe gallery is different from the first embodiment in that a cement mortar layer 101 is fixed on one surface of the elastic water stop 6 away from the right-angle steel plate 4, and the cement mortar fills the round angle of the elastic water stop 6 into an inclined surface. And a second waterproof coiled material 71 is fixed on one surface of the cement mortar layer 101 and the elastic water stop belt 6, which is far away from the right-angle steel plate 4, and two sides of the second waterproof coiled material 71 are fixedly connected with the additional waterproof coiled material 8 through the sealing glue layer 3.
The cement mortar layer 101 fills the fillet of the elastic water stop 6 for the inclined plane, so that the bending angle of the second waterproof roll 71 is reduced, and the cracking of the second waterproof roll 71 is effectively reduced.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
