Description of the labeling: 1. the tower comprises tower legs, 2, a tower foundation pile cap, 3, a pile foundation, 4, a foundation pit, 5, an impermeable membrane, 6, a backfill layer, 7, a transition cushion layer, 8 and an anti-impact layer.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, an anti-seepage and anti-impact structure for a tower foundation comprises a foundation pit 4 surrounding the tower foundation, an anti-seepage film 5 laid in the foundation pit 4, and a backfill layer 6 and an anti-impact layer 8 filled in the foundation pit 4. It should be noted that the tower footing is divided into a tower leg 1, a tower footing cap 2 and a pile foundation 3 from top to bottom in sequence.
Wherein: the foundation pit 4 is an inverted quadrangular frustum pyramid-shaped structure (i.e. the foundation pit 4 has a side slope), and the impermeable membrane 5 is a geomembrane (the specification of the geomembrane selected for the embodiment is 500 g/m) 2 ) The backfill layer 6 is clay, and the anti-impact layer 8 is dry masonry.
The dry masonry is a block stone masonry which is tightly embedded with each other, a cementing material is not needed, the dry masonry is kept stable under the action of external force by means of the self weight of stones and the friction force between contact surfaces of the stones, water flows smoothly in flood beaches and terraces, fine soil around the tower foundation is prevented from being brushed by the water flows, the elasticity of the protection structure is enhanced, and the impact effect of the external force is resisted.
The impermeable membrane 5 is adhered around the side wall of the tower foundation cap 2 and the lower edge thereof extends to the bottom surface of the foundation pit 4. Preferably, the lower edge of the impermeable membrane 5 extends vertically outward from the foundation cap 2 to the bottom surface of the foundation pit 4 by at least 1m.
The backfill layer 6 and the impact resistant layer 8 are sequentially filled in the foundation pit 4 from bottom to top. Preferably, the periphery of the impact layer 8 is at least 4m from the edge of the tower foundation cap 2.
In one embodiment, a transition pad layer 7 is disposed between the impact layer 8 and the backfill layer 6. Transition bed course 7's effect prevents that clay from taking place the infiltration and warp the destruction as the transition between clay and the dry masonry, plays the effect of diffusion stress and drainage simultaneously.
Specifically, the transition pad layer 7 is a sand-stone mixture. In the sand-stone mixture, coarse, medium and small broken stone aggregates with different grain diameters and coarse sand are proportioned according to a certain proportion, and the grain composition meets the specified gradation requirement. The graded sandstone mixture has good water permeability, diffusion stress and bearing transition property, wide material source, can be obtained from local materials, is convenient for processing raw materials and mixture, and is easy for paving operation.
The construction process is as follows:
and excavating the shallow soil around the tower foundation bearing platform 2 for 2.3m to the bottom surface of the tower foundation bearing platform 2 to form a foundation pit 4, wherein the distance between the periphery of the bottom surface of the foundation pit 4 and the tower foundation bearing platform 2 is 1m, and the distance between the periphery of an opening at the top of the foundation pit 4 and the tower foundation bearing platform 2 is 4.45m.
And (3) adhering a geomembrane (generally adopting professional industrial viscose) to the periphery of the tower foundation cushion cap 2, wherein the lower edge of the geomembrane extends to the bottom surface of the foundation pit 4 and covers the bottom surface of the foundation pit 4 completely.
The construction process of the geomembrane comprises the following steps: firstly, floating slurry on the surface of the bonding part of the tower foundation cushion cap 2 and the geomembrane is removed by a steel brush, the bonding part is coated with the geomembrane-dedicated adhesive after hot melting, the coating height width is not less than 0.3m, and then the geomembrane is adhered to the geomembrane-dedicated adhesive hot melting area. For the best bond of the security seal, it is recommended to apply the glue twice: the glue solution is made to permeate into the geomembrane for the first time, which mainly plays roles of sealing, waterproofing and preventing seepage, and the glue is applied when the adhesive is cooled to be dry (not less than 1 hour); and (3) according to the environmental conditions, when the adhesive layer is cooled to be dry (about 20 minutes), spreading the geomembrane according to the design range after the adhesive layer is optimally fused, and reserving a geomembrane of 0.2m at the bonding part of the geomembrane and the tower base bearing platform 2 for settlement or stretching presetting.
After the geomembrane is laid, 1.3m thick clay is backfilled on the geomembrane, then 0.1m thick sandstone mixture is laid, and finally 1m thick dry masonry is arranged.
Generally speaking, the utility model discloses utilize prevention of seepage membrane 5's water barrier, lay it in foundation ditch 4 to make its adhesion in column foot cushion cap 2, overlap joint to foundation ditch 4 bottom surfaces simultaneously, fill backfill layer 6 and anti impact layer 8 in proper order again, thereby realize the anti-seepage anti-impact duplicate protection to column foot and dyke, construction speed is fast, and the cost is low.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
