Abstract
The invention relates to a method for processing the water leakage of a soil layer which is arranged on the bottom portion of a deep foundation pit. The method for processing the water leakage of a soil layer which is arranged on the bottom portion of a deep foundation pit is characterized in that the method comprises the following steps: V1ing, firstly, a position and the side in the bottom portion of the deep foundation pit, where leakages water are dug with a blind drainage ditch, a blind shaft is dug on the end portion of the blind drainage ditch, the blind shaft and the blind drainage ditch are communicated, and the blind drainage ditch and the blind shaft are arranged under the bottom portion of the deep foundation pit. V2ing, filter materials are backfilled in the blind drainage ditch, a drainage pipe is arranged in the blind shaft, an opening is opened on the side surface of the lower end portion of the drainage pipe, a water pump is arranged in the drainage pipe, at the same time or after the drainage pipe is arranged, the filter materials are backfilled in the blind shaft. V3ing, concrete slabs are cast on the upper portions of the blind drainage ditch and the blind shaft and the lower portion of a basement foundation slab or a foundation base. V4ing, the water pump is opened to discharge. The construction method of the invention is simple, the effect is excellent, the water leakage of the soil layer which is arranged on the bottom portion of a deep foundation pit is capable of being effectively treated.
Description
Technical field
The invention belongs to civil construction, urban construction field, be specifically related to the processing method of bottom solum trickleing water of deep building pit.
Background technology
In civil construction, urban construction field, reasons such as inside and outside phreatic head difference is very big owing to cheating behind the deep pit digging, the complexity of soil layer, Construction of Engineering Pile, the problem that before the cast of basement bottom board concrete, occurs Deep Foundation Pit substratum percolating water after all easily causing deep pit digging on earth, cause basement can't proceed construction, influence the duration, increase cost, and can bring potential safety hazard or even security incident surrounding enviroment and deep foundation ditch.
Have following two kinds of methods to handle Deep Foundation Pit substratum percolating water at present:
1, the method for backfill foundation ditch, this method cost height, long in time limit is after especially the soil of foundation ditch has dug, just there is not soil can in time carry out backfill at all, how about develop down owing to estimating to cheat substratum percolating water simultaneously, how high backfill is, the backfill area is much all is unable to estimate poor effect.
2, the method in sand bag or mount cofferdam, this method must be carried out the mud jacking sealing after adopting sand bag or mount cofferdam, otherwise basement still can't be proceeded construction.
Above-mentioned two kinds of method poor effect do not solve the problem of Deep Foundation Pit substratum percolating water well.
Summary of the invention
The object of the present invention is to provide the processing method of simple, the effective bottom solum trickleing water of deep building pit of a kind of method.
To achieve these goals, the present invention adopts following technical scheme: the processing method of bottom solum trickleing water of deep building pit,
It is characterized in that it comprises the steps:
1) weeper drain is dug on position or the next door that percolating water has at first taken place at the bottom of Deep Foundation Pit, digs blind shaft in the weeper drain end, and blind shaft is connected with weeper drain;
2) backfill filtering material in weeper drain; Gutter is set in blind shaft, and the side perforate of the bottom of gutter is installed in water pumper in the gutter; When gutter is set or afterwards, backfill filtering material in blind shaft;
3) at the upper pouring concrete plate of weeper drain and blind shaft;
4) starting water pumper drains the water in weeper drain, the blind shaft.
When the water amount of seepage at the bottom of the Deep Foundation Pit influences basement bottom board or foundation construction, the peripheral position slip casting of percolating water has taken place at the bottom of Deep Foundation Pit, or in the source, source of water Grouting Pipe has been set and carries out slip casting.
The concrete plate be positioned at basement bottom board or the basis end below.
The present invention has following advantage:
1, thereby the present invention carries out organized row's seepage at basement bottom board or basis by weeper drain, blind shaft are set to Deep Foundation Pit substratum percolating water at the end, and the backfill filtering material guarantees a draining and silt particle can not run off;
2, the present invention forms the concrete cover plate of weeper drain, blind shaft at the top and the following pour concrete plate of the basement bottom board or the end, basis of the top of weeper drain and blind shaft, both can guarantee that basement bottom board or basis can carry out job execution; Also can be used as simultaneously the bed course of basement bottom board and cushion cap;
3, the method for the invention is simple, effective, can effectively handle bottom solum trickleing water of deep building pit.
Description of drawings
Fig. 1 is weeper drain, blind shaft, filtering material, draining steel pipe, the water pumper of the embodiment of the invention 1, the layout schematic diagram of concrete plate;
Among the figure: at the bottom of the 1-Deep Foundation Pit, 2-weeper drain, 3-blind shaft, 4-filtering material, 5-gutter, 6-water pumper, 7-concrete plate, 8-Grouting Pipe, the outlet pipe of 9-water pumper.
The specific embodiment
Embodiment 1: referring to Fig. 1, and the processing method of bottom solum trickleing water of deep building pit, it comprises the steps:
1) at first at the bottom of Deep Foundation Pit 1 position or the next door that percolating water has taken place dig weeper drain 2, blind shaft 3 has been dug in the end of weeper drain 2, blind shaft 3 is connected with weeper drain 2;
2) backfill filtering material 4 (filtering material is the sandstone of grating etc.) in weeper drain 2; Many gutters 5 (gutter is avoided the cushion cap setting) are set in blind shaft 3, the side perforate of the bottom of gutter 5, water pumper 6 is installed in (so that extract the water that causes blind shaft 3 from weeper drain 2 out, it is outer that the outlet pipe 9 of water pumper leads to gutter 5) in the gutter 5; Gutter 5 is metal tube, glass reinforced plastic pipe, concrete pipe or plastic pipe; When gutter 5 is set or afterwards, backfill filtering material 4 in blind shaft 3 (filtering material is the sandstone of grating etc.);
3) at the top of weeper drain 2 and top (on the filtering material 4) the pour concrete plate 7 of blind shaft 3 (forming the concrete cover plate of weeper drain 2, blind shaft 3), concrete plate 7 is positioned at basement bottom board or the end, basis following (being the basement bottom board or the end, basis on the concrete plate 7);
4) start water pumper and the water in weeper drain, the blind shaft is drained (outlet pipe 9 by water pumper is drained).
In order better to solve percolating water, whether the present invention also can influence basement bottom board or foundation construction decision according to water amount of seepage and whether 1 the peripheral position slip casting of percolating water take place at the bottom of Deep Foundation Pit, or in the source, source of water Grouting Pipe 8 is set and carries out slip casting; When water amount of seepage influences basement bottom board or then slip casting of foundation construction, Grouting Pipe 8 is arranged in the peripheral position that percolating water takes place or the source, source of water, adopt chemical grouting methods such as two fluid grouting to carry out slip casting then, the advantage of chemical groutings such as two fluid grouting is to play the sealing effect rapidly;
