Abstract
The invention relates to a building basement waterproof method and a building basement waterproof structure which has the underground waterproof function and is suitable for a closed underground structure formed through a basement floor and a reinforced concrete wall on the lower portion of the basement floor, and belongs to the field of waterproof technology of building underground engineering. To guarantee that the building underground engineering meets the waterproof performance, the construction technology of storing part of air under the basement floor through the structure sealing performance is utilized, the basement floor is effectively isolated from underground water based on the air pressure balancing principle through the technology, and therefore the waterproof effect is achieved. The building basement waterproof method and the building basement waterproof system can meet the functional requirements for the underground engineering waterproofing, seepage resisting and corrosion preventing and the like, and have the advantages that the structure is simple, construction is convenient and engineering cost is saved. Meanwhile, cost is greatly saved, and economic benefits are obvious.
Description
Technical field
The present invention relates to a kind of building basement waterproof method and structure thereof, have underground waterproof function, 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 guaranteeing that building underground construction meets water resistance, invented 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 invention not only meets underground project waterproof, the functional requirement such as impervious, anticorrosion, and has advantages of simple structure, easy construction, saving engineering cost.
Summary of the invention
The object of this invention is to provide a kind of building basement waterproof method and structure thereof, for not doing the situation of waterproof coiled material on basement bed course because of odjective cause, propose the constructure scheme of a kind of rational in infrastructure, easy construction, economy.
The object of the invention is to be achieved through the following technical solutions, a kind of building basement waterproof method, it is characterized in that, described method is under the base plate of basement, to construct the confined space of storing air, utilize the air balance groundwater pressure in confined space, stop underground water upwards to enter basement bottom board.
Realize the structure of building basement waterproof method, comprise body of wall and the base plate of basement, the foundation ditch under base plate, it is characterized in that, near constructing some grooves of 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 present invention meets water resistance for guaranteeing building underground construction, utilizes the constructing technology of structure airtight performance storage part air under basement bottom board, and this technology utilizes atmospheric pressure equilibrium principle that basement floor and underground water are effectively isolated, thereby reaches waterproof effect.The present invention 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention;
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.
The specific embodiment
Further illustrate in conjunction with the accompanying drawings and embodiments the present invention.The method of the invention is to construct at the base plate of basement 1 confined space of storing air for 2 times, utilizes the air balance groundwater pressure in confined space, stops underground water upwards to enter basement 1 base plate 2.
Realize the present embodiment storage air method structure as shown in Figure 1 and Figure 2, direction in length and breadth along 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, along foundation ditch 5 planes, arrange together the every 2m of direction left and right in length and breadth.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.
