Abstract
The utility model relates to a building basement waterproof structure and belongs to the technical field of waterproofness of building underground engineering. The building basement waterproof structure has an underground waterproof function and is suitable for underground construction of a sealing structure formed by a bottom plate of a basement and a reinforced concrete wall body at the lower part of the bottom plate. The building basement waterproof structure is mainly characterized in that a plurality of longitudinal and transverse grooves are formed in a pure soil foundation plane in a foundation pit close to the bottom plate, notches of the grooves are covered, and a concrete cushion layer is formed between the grooves and the bottom plate. The building basement waterproof structure has the beneficial effects that by utilizing a construction technology that a part of air can be stored in the bottom plate of the basement through the structure airtightness, the bottom plate of the basement is effectively separated from underground water by utilizing an air pressure balance principle, so that a waterproof effect is realized; the building basement waterproof structure not only meets the requirements of underground engineering waterproofness, seepage resistance and corrosion resistance and the like, but also has the advantages of simple structure, convenience in construction and low engineering cost; meanwhile, the cost is greatly saved, and the economic benefit is remarkable.
Description
Technical field
The utility model relates to a kind of building basement waterproof construction, has underground waterproof function, and the reinforced concrete wall that is applicable to basement bottom board and its underpart forms the subsurface structure of enclosed construction, belongs to the waterproof technique field of building underground construction.
Background technology
In some building underground engineering construction, the restriction that basement bottom board waterproof is subject to the reasons such as geological conditions, Structural Tectonics, execution conditions and economy is not easy to carry out outer subsides coiled material construction,
For ensureing that building underground construction meets water resistance, utility model a kind of constructing technology that utilizes structure airtight performance storage part air under basement bottom board, this technology utilizes atmospheric pressure equilibrium principle that basement floor and underground water are effectively isolated, thereby reaches waterproof effect.This utility model not only meets underground project waterproof, the functional requirement such as impervious, anticorrosion, and has advantages of simple structure, easy construction, saving engineering cost.
Utility model content
The purpose of this utility model is to provide a kind of building basement waterproof construction, for the situation that can not do waterproof coiled material because of odjective cause on basement bed course, proposes the constructure scheme of a kind of rational in infrastructure, easy construction, economy.
The purpose of this utility model is achieved through the following technical solutions, a kind of building basement waterproof construction, comprise body of wall and the base plate of basement, foundation ditch under base plate, it is characterized in that, near some grooves of constructing vertical and horizontal in the plain earth foundation plane in the foundation ditch of base plate, the notch capping of groove, is concrete cushion between each groove and base plate.
The degree of depth of described groove and width are 28-32cm, and the spacing of each groove is 1.9-2.1m.
Described flute surfaces is amassed and accounted for the foundation ditch gross area is 19-21%.
Described groove notch adopts template capping, and template both sides width exceeds groove 15cm suitable for reading, and the split joint of capping is tight.
The thickness of described concrete cushion is not less than 100mm.
The utility model meets water resistance for ensureing building underground construction, utilize the constructing technology of structure airtight performance storage part air under basement bottom board, this technology utilizes atmospheric pressure equilibrium principle that basement floor and underground water are effectively isolated, thereby reaches waterproof effect.The utility model not only meets underground project waterproof, the functional requirement such as impervious, anticorrosion, and has advantages of simple structure, easy construction, saving engineering cost.Greatly save cost, economic benefit is obvious simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the local structure for amplifying schematic diagram in Fig. 1;
In figure, 1 basement, 2 base plates, 3 bed courses, 4 grooves, 5 foundation ditches, 6 element soil, 7 templates.
Detailed description of the invention
Further illustrate in conjunction with the accompanying drawings and embodiments the utility model.The utility model structure as shown in Figure 1 and Figure 2, along the direction in length and breadth of basic plane, when foundation ditch 5 element soil 6 rammers are filled out, base plate 2 across in≤1m is with external position, in native 6 planes of element, excavate groined type groove 4, the degree of depth and the width of groove 4 are 30cm, arrange together the every 2m of direction left and right in length and breadth along foundation ditch 5 planes.Whole foundation ditch 5 planes form a groined type plane that groove is crisscross, and as shown in Figure 1, then in groined type groove 4 covering template 7 suitable for reading, template 7 both sides width exceed groove 15cm suitable for reading, and capping template 7 split joints are tight, prevent that concrete from pouring into.After whole foundation ditch 5 cappings complete into rammer, foundation ditch 5 as shown in Figure 2, is finally built bed course 3 concrete.The degree of depth of groove and width are 28-32cm, and the spacing of each groove is 1.9-2.1m, and flute surfaces is amassed and accounted for the foundation ditch gross area is 19-21%, and the thickness of concrete cushion is not less than 100mm.
It is simple, easy to operate that foundation ditch after the technical finesse of the present embodiment utilization storage air method underground waterproof has technique, waterproof, impervious successful, and cost is lower, and techno-economic effect is obvious.
