Abstract
The utility model discloses a blind ditch structure used for a bottom plate to resist floating, belongs to the technical field of construction and particularly relates to design technology in a construction underground structure. The blind ditch structure used for the bottom plate to resist floating is characterized in that the bottom plate of a bearing building and a cushion layer are supported by perpendicular pillars, a coarse sand layer and a rubble layer are sequentially arranged under the bottom plate and the cushion layer and a water permeating and draining pipe made of unplasticized polyvinyl chloride (UPVC) is transversely arranged in the rubber layer. The diameter of the water permeating and draining pipe is 100 millemeters. One end of the water draining pipe penetrates through a wall of a water collecting well. The bottom of the water collecting well is more than 1 meter below the bottom plate. An automatic floating ball pump is arranged in the well and keeps water level under a raft bottom. The blind ditch structure used for the bottom plate to resist floating has the advantages that the phenomenon that due to insufficient weight of a structure, the structure can not resist floating force generated by underground water and floats up is avoided, structural quality of the bottom plate is ensured, construction is convenient, the blind ditch structure is reliable and safe, and cost is low.
Description
Technical field
Belong to technical field of building construction, exactly relate to the designing technique of building operations underground structure.
Background technology
In recent years because the large-scale development of the underground space, with the podium of basement and singly to build the buildings such as basement of formula more and more, the degree of depth is also deepened gradually.Because its top number of plies is few, dead load often is not enough to resist the buoyancy that underground water produces, and foundation construction requires to take necessary measure of anti float.Traditional method adopts dead load or adds anchor pole, for preventing that heavy rain or regional water level from rising the building base plate is impacted, and builds the flood control and water drain canal by laying bricks or stones at the building periphery, and for not affecting building periphery overall appearance, water channel can be made underground buried type.
Summary of the invention
The utility model provides a kind of in time discharges outside the base plate underground water under the base plate, reduces underground water to a kind of french drain structure for the base plate anti-floating of the buoyancy of base plate.
The technical scheme that the utility model is taked:
A kind of french drain structure for the base plate anti-floating, the base plate and the bed course that comprise the load bearing construction thing, its scheme is: the base plate of load bearing construction thing and bed course are supported by vertical stake, base plate and bed course below have coarse sands layer and macadam successively, horizontal traverse the permeable gutter of the UPVC material composition of 100 millimeters of diameters in macadam, one end of gutter penetrates the collecting well borehole wall, at base plate below 1 meter, be equipped with in the well and make it self-draining with the water level automatic ball float water pump at the bottom of the raft plate all the time at the bottom of the collecting well.
Good effect behind enforcement the utility model is:
By enforcement of the present utility model, to have avoided because dead load is not enough, the structure that causes descending irresistibly the buoyancy of water generates to cause is floated phenomenon.Guaranteed the architecture quality of base plate and bed course, easy construction, safe and reliable, cost is low.

The specific embodiment
Now the utility model is described in further detail by reference to the accompanying drawings
The french drain structure that the base plate anti-floating is used, the base plate and the bed course that comprise the load bearing construction thing, its formation is: the base plate of load bearing construction thing and bed course 1 are supported by vertical stake, base plate and bed course below have coarse sands layer 2 and macadam 3 successively, horizontal traverse the permeable gutter 4 of the UPVC material composition of 100 millimeters of diameters in macadam, one end of gutter penetrates collecting well 5 boreholes wall, at base plate below 1 meter, be equipped with in the well and make it self-draining with the water level automatic ball float water pump 6 at the bottom of the raft plate all the time at the bottom of the collecting well.
Described permeable gutter 4 is cylindric, gutter first half tube walls, evenly is covered with soya bean size pore, and tube wall is outer is wrapped by one deck geotextiles.
Claims (2)
1. french drain structure that is used for the base plate anti-floating, the base plate and the bed course that comprise the load bearing construction thing, it is characterized in that: the base plate of load bearing construction thing and bed course (1) are supported by vertical stake, base plate and bed course below have coarse sands layer (2) and macadam (3) successively, horizontal traverse the permeable gutter (4) of the UPVC material composition of 100 millimeters of diameters in macadam, one end of gutter penetrates collecting well (5) borehole wall, at base plate below 1 meter, be equipped with in the well and make it self-draining with the water level automatic ball float water pump (6) at the bottom of the raft plate all the time at the bottom of the collecting well.
2. a kind of french drain structure for the base plate anti-floating according to claim 1, it is characterized in that: described permeable gutter (4) is cylindric, and the even tube wall of the first half is being covered with the hole, tube wall is outer is wrapped by one deck geotextiles.
