Description

Waterproof structure for plugging rear holes of bottom plate
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to a waterproof construction that is used for shutoff behind bottom plate hole.
Background
In the construction process of constructional engineering, holes are reserved on the bottom plate to be plugged for the second time due to site construction requirements or process requirements, the bottom plate at the positions of the holes cannot be connected into a whole in a waterproof mode, and the connecting parts of new and old concrete have large water seepage hidden dangers.
Disclosure of Invention
In order to overcome the technical defect of the seepage risk that building engineering bottom plate hole secondary shutoff exists among the prior art, the utility model provides a waterproof construction for shutoff behind bottom plate hole utilizes the oleamen caulking to close head, secondary coiled material construction formation confined bottom plate waterproof layer, has solved above-mentioned technical problem.
The utility model discloses a following technical scheme realizes above-mentioned purpose, a waterproof structure for shutoff behind bottom plate hole, including former waterproof roll material layer, oleamen caulking, level mix grit backfill layer, waterproof bed course, new waterproof roll material layer and micro-expansion concrete layer, former waterproof roll material layer carries out construction process through the oleamen caulking in hole lateral wall department and receives the head, level mix grit backfill layer and fill and accomplish the shutoff in the hole lower part, waterproof bed course sets up at level mix grit backfill layer upper portion, new waterproof roll material layer is pasted on waterproof bed course upper portion, and the end position carries out the overlap joint with former waterproof roll material layer at hole lateral wall and top surface and forms the bottom plate waterproof layer, micro-expansion concrete layer pours on new waterproof roll material layer upper portion, and parallel and level mutually with bottom plate top plane.
The caulking ointment is a high-viscosity plastic paste, is gradually hardened after oxidation, and protects the head-closing position of the original waterproof roll layer from being damaged when the original waterproof roll layer is exposed for a long time.
The waterproof structure for plugging the hole of the bottom plate is characterized in that after the construction of the new waterproof roll layer on the graded gravel backfill layer and the waterproof cushion layer is completed, the new waterproof roll layer is in lap joint with the original waterproof roll layer on the side wall of the hole along the waterproof cushion layer, and the head is folded at the periphery of the top surface of the hole to form a waterproof layer of the bottom plate.
The thickness of the micro-expansion concrete layer is 2 times of that of the bottom plate, and is higher than that of the bottom plate concrete at the periphery by a mark.
Generally, through the utility model discloses above technical scheme who conceives compares with prior art, can reach following beneficial effect: the utility model relates to a waterproof construction for shutoff behind bottom plate hole, construction convenience utilizes the caulking oleamen to carry out the coiled material and receives the head, and the durability is good, utilizes the level to join in marriage the grit and accomplishes the hole lower part and backfill, economical and practical, utilizes the micro-expansive concrete to accomplish hole upper portion and backfill, prevents to combine not the inseparable condition appearance because of the new and old concrete that concrete shrinkage deformation leads to, utilizes the reasonable overlap joint of twice coiled material, forms confined bottom plate waterproof layer, guarantees water-proof effects, and whole bottom plate hole shutoff waterproof construction can effectively avoid the seepage.
Drawings
The following detailed description of embodiments of the present invention is provided with reference to the accompanying drawings, in which:
fig. 1 is a schematic sectional structure view of a waterproof structure for plugging a hole of a bottom plate according to the present invention;
in the figure: 1-original waterproof roll material layer, 2-factice caulking, 3-graded sandstone backfill layer, 4-waterproof cushion layer, 5-new waterproof roll material layer and 6-micro-expansion concrete layer.
Detailed Description
As shown in fig. 1, it is a schematic cross-sectional structure diagram of a waterproof structure for plugging holes on a bottom plate, comprising an original waterproof roll layer 1, an ointment caulking 2, a graded sandstone backfill layer 3, a waterproof cushion layer 4, a new waterproof roll layer 5 and a micro-expansion concrete layer 6.
The original waterproof roll layer 1 is a waterproof component of a bottom plate around the hole, the hole is disconnected and continuously exposed in the air until the hole is closed, a groove is reserved on the side wall of the hole, the head of the original waterproof roll layer 1 is collected at the groove, and the head is collected by adopting an ointment caulking 2 for a construction process.
When the hole is plugged, the graded sandstone backfill layer 3 is used for completing the backfill of the lower part of the hole, a waterproof cushion layer 4 is constructed on the upper part of the graded sandstone backfill layer 3, a new waterproof roll material layer 5 is adhered on the waterproof cushion layer, and the new waterproof roll material layer 5 and the original waterproof roll material layer 1 are overlapped on the side wall and the top surface of the hole to form a closed waterproof roll material layer.
And pouring the micro-expansion concrete layer 6 to the top of the bottom plate, and adopting the micro-expansion concrete 6 with the same height as the top plate to avoid the technical problem of water seepage of the construction cold joint between the new concrete and the old concrete.
The utility model discloses when the construction, adopt 2 construction process of oleamen caulking to receive the head to handle former waterproofing membrane layer 1, the durability is strong, has avoided former waterproofing membrane 1 to expose for a long time and has received the head position in the air and destroyed. And the graded gravel backfill layer 3 is adopted to complete the backfill of the lower part of the hole, so that the cost is saved and the bearing capacity requirement is met. The waterproof cushion layer 4 provides construction conditions for the new waterproof roll material layer 5, the new waterproof roll material layer 5 and the original waterproof roll material layer 1 are in lap joint on the side wall and the top surface of the hole to form a closed waterproof roll material layer, and the construction cold joint water seepage between new concrete and old concrete is avoided by adopting the micro-expansion concrete 6 with a high grade.
The utility model discloses rationally utilize oleamen caulking 2 construction process to receive the head to handle former waterproof coil stock layer 1. The used materials are conventional materials, so the material is convenient to purchase and construct and has good waterproof effect. By adopting the waterproof structure in the basement bottom plate hole plugging construction process, a closed waterproof layer can be formed, the easy-to-leak part is reinforced, and the occurrence of water seepage accidents after the bottom plate hole is plugged is effectively avoided.
It will be understood by those skilled in the art that the foregoing is merely a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included within the scope of the present invention.
