Description
Technical field
This utility model belongs to the protection of Hydraulic and Hydro-Power Engineering landslide and the technical field in the field of improvement, is more specifically
Deep layer slip mass depth osculum overlap joint combination type in the hole protection device.
Background technology
Implementing osculum in gliding mass is landslide disaster prevention means widely used both at home and abroad at present.Dredged by osculum
Row's internal subsoil water in landslide is simultaneously greatly lowered its water level in a short time, can reach the purpose effectively improving Landslide Stability.Mirror
In osculum, there is the features such as cheap, maneuverability, easy construction, osculum technology obtains in many landslide engineerings
Application, and achieve preferable prevention effect, especially for the landslide engineering of caused by groundwater, its effect is more significantly.
For meeting osculum service requirement steady in a long-term, prevent sillar, hack and granule from depositing under flow action draining
Kong Zhiqi lost efficacy, and generally requires and carries out in the hole protection to osculum.Conventional in the hole protection device is typically by multistage plastic filter pipe
Or hard u-pvc drain pipe (perforate) is formed by connecting.
For deep layer slip mass (slip mass depth is more than 25m), for guaranteeing osculum entrance permeable stratum, deep osculum
Hole depth or up to 30m-60m (general osculum hole depth about 10m-20m).In view of substance of landslide composition is various, geological conditions is multiple
Miscellaneous, the reason such as osculum hole depth is big, hole quality is poor, hole wall is coarse, exist during conventional in the hole protection device practice of construction
Following problem:
1st, in the hole protection device installation difficulty, card pipe, disconnected pipe phenomenon take place frequently
(1) plastic filter pipe by diameter 2mm about the mutual contact clinkering of rigid plastics strand become solid netted, many spaces
The body of rod, joint length 2-4m, voidage reaches 80% 95%, and its mechanical characteristics shows linear flexible object, and length is longer, soft
Property feature is more obvious.
Practice of construction shows, during installing push, with the increase pushing depth, radial thrust passes plastic filter pipe
Power effect substantially reduces.Because hole wall is coarse, hole quality is poor, under the dual function of thrust and wall drag, filter pipe warp
Often can be distorted bending in the larger pipeline section of resistance, or even present " v shape ", lead to card to be run affairs therefore occur.With osculum
Depth down, this in the hole protection device installation process difficulty is also bigger.
(2) hard u-pvc drain pipe is the hard plastic pipe with Corvic as raw material, in open circles tubulose,
Wall thickness is generally 2mm-4mm.For ensureing drainage effect, need to be general to front end u-pvc drain pipe pipeline section hole wall perforate, cinclides aperture
For 10mm-15mm, spacing 3cm-5cm, blossom type interlaced arrangement.U-pvc drain pipe after perforate is commonly called as " floral tube ".
Practice of construction shows, when push fixes a drainpipe, front end floral tube section often occurs multiple cinclides and drilling hole
Wall remaining objects (as local crowning sillar) are engaged, and because hole wall is coarse, hole quality is poor, and gmatjpdumamicss are larger, often send out
Raw card pipe.
(3) if occur in the hole protection device to push the phenomenons such as installation difficulty, card pipe in actual osculum work progress,
Be accomplished by repeatedly pumping adjustment, once pump dynamics control improper will lead to plastic filter pipe or u-pvc drain pipe junction or
Person's body itself ruptures, and thus cause osculum is scrapped, construction speed is obstructed, economic loss a series of problems, such as.
2nd, water drainage effect on driving birds is not good, easily lost efficacy
(1) engineering practice is it has been shown that carry out draining, draining using conventional in the hole protective measure in creep large deformation slip mass
Hole drainage effect is not typically good.Compared to plastic filter pipe, u-pvc drain pipe material porosity is low, and it is poor to lead drainage effect, is difficult to
The internal subsoil water in white-out landslide in time.Although plastic filter pipe porosity is big, it is good, due to lacking outside it to lead drainage effect
Loaded filter is protected, osculum running, and substantial amounts of hack and granule deposit in plastic filter pipe body so as to gradually lose work
With causing osculum to lose efficacy.
(2) because in the hole protection device pushes difficulty, its fitting depth is difficult to meet design requirement hole depth it is impossible to extend into
In permeable stratum, lead to drainage effect not good.On the other hand, in osculum running, in the hole protection device is not mounted to
, easily there is failure by shear with landslide large deformation in the boring hole section of position, thus draining was lost efficacy, its service life of serious curtailment, and lead
Cause later maintenance costly.
