Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Referring to fig. 1, the present invention provides a basement exterior wall structure at a deep foundation pit decoration stage, including: the basement outer wall comprises a basement outer wall body 1, a cement-based capillary crystalline waterproof layer 3, a first interlayer plastic plate 4 and a permanent guide and drainage layer 5.
Wherein, the cement-based permeable crystallization type waterproof layer 3 is coated on the inner side of the basement exterior wall body 1. The inner side of the basement outer wall body 1 is poured to form a bottom plate 2. A drainage ditch 20 is formed at the intersection of the bottom plate 2 and the basement exterior wall body 1. A water collecting pit is formed in the bottom plate 2;
the first interlayer plastic plate 4 is laid on the bottom plate 2. The first mortar protective layer 41 is poured on the upper part of the first interlayer plastic plate 4. The first interlayer plastic plate 4 is arranged in a clearance with the basement outer wall body 1.
The permanent drainage layer 5 includes a second interlayer plastic sheet 51 and a finishing layer 52. Specifically, the second interlayer plastic plate 51 is mounted on the inner side of the basement exterior wall body 1. The finish coat 52 is poured on one side of the second interlayer plastic plate 51 far away from the basement exterior wall body 1, and the lower end of the second interlayer plastic plate 51 extends into the gap between the first interlayer plastic plate 4 and the basement exterior wall body 1.
In a preferred embodiment, the thickness of the laminated plastic plate is 10 mm.
In this embodiment, a steel wire mesh is laid on the inner side of the basement exterior wall body 1, and the second interlayer plastic plate 51 is laid between the steel wire mesh and the basement exterior wall body 1.
According to the underground outdoor wall structure in the decoration stage of the deep foundation pit, the permanent drainage cavity is arranged between the plastering layer and the basement outer wall body, so that the leakage water is guided to reach the floor of the bottom plate to the ditch through the drainage cavity, the leakage water of the outer wall is discharged through the floor drainage system of the bottom plate, the drainage is taken as the leading factor in the whole construction, and the leakage plugging amount is greatly reduced; through the arrangement of the permanent drainage voids, the defects of flatness and verticality deviation of the wall surface of the outer wall structure can be overcome, micro water leakage points which do not influence stress safety are allowed to exist in the structure, and the workload of cleaning and repairing a base layer on the surface of the wall before plastering construction of decoration and finishing is reduced; the permanent drainage space is small in thickness, only about 10mm, and compared with the conventional drainage method that the lining wall and the drainage blind ditch are additionally arranged in the traditional basement, the usage amount of building materials is reduced, and meanwhile, the utilization rate of the basement space is improved.
The underground outdoor wall structure at the decoration stage of the deep foundation pit adopts the cement-based permeable crystallization type waterproof coating as the waterproof layer of the underground outdoor wall. The coating contains a plurality of active chemical substances, utilizes the inherent chemical characteristics and porosity of cement concrete, takes water as a carrier, and is transmitted and filled in concrete micropores and capillaries by virtue of osmosis to catalyze the incompletely hydrated components in the concrete to be hydrated again to form water-insoluble dendritic crystals which are combined with the concrete into a whole, thereby blocking water and other liquid in any direction. Because the special catalyst is activated when meeting water, new fine gaps are generated due to vibration or other reasons after a plurality of years, and once water permeates, new crystals are generated to block the water. The said concrete can reach the effects of preventing water and moisture, protecting reinforcing steel bar and strengthening concrete structure.
On the other hand, the underground outdoor wall structure in the deep foundation pit decoration stage achieves the purpose of draining water through the floor drainage ditch provided with the second interlayer plastic plate and the bottom plate. The space between the second interlayer plastic plate with the pivot and the outer wall and the bottom plate is utilized to make a permanent hollow layer, namely, a drainage layer is guided, a drainage passage is formed to drain water and prevent moisture, the basement water seepage can be guided to a diversion trench, finally the water seepage is guided into a water collecting pit, and the water is discharged through a water pump, so that the purpose that the outer wall surface and the ground of the basement have no seepage points and watermarks is achieved, and the dryness of the basement is ensured.
According to the basement outer wall structure in the deep foundation pit decoration stage, the expansion bolts and the accessories thereof are adopted to fix the second interlayer plastic plate and the steel wire mesh sheet at one time, so that materials and labor are saved, and the construction period is shortened; the method of combining water proofing and drainage is comprehensively utilized, the water seepage condition of the outer wall of the basement is effectively avoided, and secondary reworking caused by improper construction method is also avoided.
The underground outdoor wall structure in the decoration stage of the deep foundation pit is simple in composition, so that compared with other traditional outer wall waterproof construction methods, the underground outdoor wall structure has the advantages that less construction waste is generated in the construction process, the variety is more single, and the centralized treatment is facilitated.
The basement outer wall structure at the decoration stage of the deep foundation pit adopts the cement-based permeable crystalline waterproof coating, so that cracks formed at the later stage can be sealed, the waterproof property of the structure is enhanced, and the repairing material for the base layer is saved.
The above description is only a preferred embodiment of the application and is illustrative of the principles of the technology employed. It will be understood by those skilled in the art that the scope of the present invention is not limited to the specific combination of the above-mentioned features, but also covers other embodiments formed by any combination of the above-mentioned features or their equivalents without departing from the spirit of the present invention.
