Description

Technical Field

[0001] The invention belongs to the technical field of building engineering, and in particular relates to a waterproof structure of a planting roof expansion joint and a construction method thereof. Background Art

[0002] An expansion joint is formed between the first concrete structure of the main building and the second concrete structure of the planting roof. The top of the first concrete structure is higher than the top of the second concrete structure, and a planting area is provided on the top of the second concrete structure. Since the expansion joint opens upward, the waterproof effect is poor. Therefore, a transverse anti-ridge covering the top opening of the expansion joint is provided on the top of the first concrete structure. The top of the second concrete structure extends upward to form a vertical anti-ridge. An entrance and exit for transferring the opening of the expansion joint to the side is reserved between the top of the vertical anti-ridge and the bottom of the transverse anti-ridge. Since the formed expansion joint entrance and exit are usually small, it is difficult to enter for waterproofing membrane. Construction, and the quality of the construction of the structure will greatly affect the anti-leakage effect of the junction; and after the waterproof membrane is constructed, the slope will be found on the top of the concrete structure below the entrance and exit of the expansion joint before subsequent construction, using a crushed stone / pebble / sand and gravel hydrophobic layer. This method can theoretically drain and filter. After construction in relevant areas of the project test, sand, soil, garbage, etc. will be filled and accumulated in the stone cracks after being washed by rainwater, causing blockage. After blockage, since the hydrophobic structure is located below, it is difficult to dredge, which increases the maintenance cost. Therefore, we propose a waterproof structure for expansion joints of planted roofs and a construction method thereof to solve the above problems. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a waterproof structure of expansion joints of a planting roof and a construction method thereof, which solves the problems of drainage blockage and difficulty in dredging.

[0004] The present invention is implemented by the following scheme: A waterproof structure for expansion joints of a planting roof, comprising:

[0005] A drainage pool is arranged on the top of the second concrete structure and is located between the planting area and the vertical anti-bank, and the water inlet of the drainage pool faces upward;

[0007] A concrete protective layer is laid along the outer surface of the waterproof membrane and forms part of the wall of the drainage pool;

[0008] The filter plate is sealed at the water inlet of the drainage pool.

[0009] A further improvement of the waterproof structure of expansion joints of planted roofs of the present invention is that the planting area is backfilled with planting soil blocks, a masonry wall is provided on one side of the planting soil blocks adjacent to the drainage pool, and the masonry wall forms the remaining pool wall of the drainage pool.

[0012] A further improvement of the waterproof structure of the expansion joint of the planting roof of the present invention is that the bottom wall of the drainage pool is inclined from an end adjacent to the vertical anti-slope to an end adjacent to the drainage pipe.

[0019] A further improvement of the construction method of the expansion joint waterproof structure of the planting roof of the present invention is that before constructing the waterproof membrane, a sealant is provided and filled between the horizontal anti-ridge and the vertical anti-ridge to prevent water from entering the expansion joint through the inlet and outlet of the expansion joint.

[0020] A further improvement of the construction method of the waterproof structure of the expansion joint of the planting roof of the present invention is that when constructing the drainage pool, planting soil blocks are backfilled in the planting area at the same time, and a masonry wall is built on one side of the planting soil blocks adjacent to the drainage pool, so that the masonry wall forms the remaining pool wall of the drainage pool.

DETAILED DESCRIPTION

[0026] In order to solve the problem of drainage blockage and dredging difficulty, the present invention provides a waterproof structure of expansion joints of a planted roof and a construction method thereof. The following is a further description of the waterproof structure of expansion joints of a planted roof and a construction method thereof with reference to a specific embodiment and the accompanying drawings.

[0027] See also Figure 1 As shown, a waterproof structure for expansion joints of a planting roof comprises:

[0028] A drainage pool 7 is arranged on the top of the second concrete structure 13 and between the planting area and the vertical anti-ridge 14, and the water inlet 12 of the drainage pool 7 faces upward;

[0029] A waterproofing coiled material 5, wherein a first end of the waterproofing coiled material 5 is sandwiched between the drainage pool 7 and the vertical anti-ridge 14, and extends upward to block the entrance and exit 2 of the expansion joint, and a second end of the waterproofing coiled material 5 is sandwiched between the drainage pool 7 and the top of the second concrete structure 13, and extends to the planting area;

[0030] A concrete protective layer 6 is laid along the outer surface of the waterproof membrane 5 and forms part of the wall of the drainage pool 7;

[0031] The filter plate 11 is sealed at the water inlet 12 of the drainage pool 7 .

[0032] Specifically, the filter plate 11 is a drainage ditch cover plate, which is used to filter some garbage and debris, reduce the hidden danger of clogging of the drainage pool 7, and improve the drainage effect; it also solves the safety hazards such as stepping on air that may exist in the original gap structure.

[0033] The planting area is backfilled with planting soil blocks 8, and a masonry wall is provided on one side of the planting soil blocks 8 adjacent to the drainage pool 7, and the masonry wall forms the remaining pool wall of the drainage pool 7;
