Abstract
The present invention relates to a kind of membrane linkage for vacuum pump and vacuum diaphragm drainage pipe, comprise vacuum diaphragm and geotextiles, vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe, vacuum diaphragm and geotextiles are placed in the centre of vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe, vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe and vacuum diaphragm and geotextiles junction are all welded with flange, and are mutually permanently connected by flange securing member.Compared with prior art, without the need to directly through vacuum diaphragm between vacuum diaphragm top tube connector of the present invention and vacuum diaphragm lower connection pipe and vacuum diaphragm and geotextiles, but realize connecting by flanged plate, reach the object of protection vacuum diaphragm.
Description
Technical field
The present invention relates to a kind of vacuum pump of the vacuum preloading for soil body discharging consolidation, the asynchronous membrane linkage of diameter of horizontal drainage pipeline under especially a kind of vacuum pump caliber and vacuum diaphragm.
Background technology
Preloading is divided into piling prepressing and vacuum preloading two class to have engineer applied and the development of decades in China, and its design theory and construction technology are all comparatively ripe, and consolidation effect is obvious, remarkable in economical benefits.Vacuum preloading Main Function mechanism is: bleed with vacuum pump, make the vacuum that drainage system remains higher, utilize atmospheric pressure as prefabricating load, increase the effective stress of ground, be beneficial to soil body discharging consolidation, soil strength is increased, and reaches reinforcing object, it can thus be appreciated that sealing effectiveness is the key point ensureing workmanship.In vacuum preloading technique, relate to various vertical duct need through vacuum diaphragm, as horizontal drainage pipeline under: vacuum pump and film connection, monitor the vertical duct etc. that delaminating deposition and pore water pressure need to bury underground.Traditional way is, by directly on film perforate vertically wrapping up good seal with film again after allowing pipeline pass film.
Easily there is following problem in traditional way:
1, easily film is scratched when workman's membrane plastic film mulch in work progress;
2, the membrane place that acts on due to pulling force in pump process easily leaks gas;
3, usually use the caliber that draws water of the jet pump of 7.5KW for 63mm in current technique of soft soil foundation treatment, and or the diameter of horizontal drainage pipeline likely uses other the size of bellows of 63mm and 75mm in the middle of design, cause commercially can't buy PVC tee piece up to specification.
Summary of the invention
The present invention will solve the technical problem through the required sealing of vacuum diaphragm of pipeline in vacuum preloading technique, provides a kind of membrane linkage for vacuum pump and vacuum diaphragm drainage pipe.
The present invention is achieved by the following technical solutions: a kind of membrane linkage for vacuum pump and vacuum diaphragm drainage pipe, comprise vacuum diaphragm and geotextiles, vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe, be characterized in: vacuum diaphragm and geotextiles above and below place vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe respectively, vacuum diaphragm top tube connector and vacuum diaphragm lower connection pipe and vacuum diaphragm and geotextiles junction are all welded with flange, and are interconnected and fixed by flange securing member.
Vacuum diaphragm top tube connector is vertical flanged (FLGD) iron pipe; Vacuum diaphragm lower connection pipe is vertical flanged (FLGD) iron pipe or vertical flanged (FLGD) threeway iron pipe.
Vacuum diaphragm top tube connector diameter is identical with the caliber that draws water of vacuum jet pump; The horizontal drainage pipeline diameter of vacuum diaphragm lower connection pipe is identical with the caliber of horizontal drainage pipeline under film.
The invention has the beneficial effects as follows: compared with prior art; without the need to directly through vacuum diaphragm between vacuum diaphragm top tube connector of the present invention and vacuum diaphragm lower connection pipe and vacuum diaphragm and geotextiles; but realize connecting by flanged plate, reach the object of protection vacuum diaphragm.Can solve through engineering practice checking:
1, easily film is scratched when workman's membrane plastic film mulch in work progress;
2, the membrane place that acts on due to pulling force in pump process easily leaks gas;
3, draw water caliber and horizontal drainage pipeline inconsistent of the jet pump of 7.5KW, causes commercially can't buy PVC tee piece up to specification.
Accompanying drawing explanation
The structural representation of Fig. 1 to be vacuum diaphragm lower connection pipe of the present invention be threeway iron pipe;
The structural representation of Fig. 2 to be vacuum diaphragm lower connection pipe of the present invention be vertical iron pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As Fig. 1, shown in 2, the membrane linkage for vacuum pump and vacuum diaphragm drainage pipe of the present invention, comprises vacuum diaphragm and geotextiles 1, vacuum diaphragm top tube connector 2 and vacuum diaphragm lower connection pipe 3 etc.
Vacuum diaphragm and geotextiles 1 above and below place vacuum diaphragm top tube connector 2 and vacuum diaphragm lower connection pipe 3 respectively, vacuum diaphragm top tube connector 2 and vacuum diaphragm lower connection pipe 3 are all welded with flange 4 with vacuum diaphragm and geotextiles 1 junction, and are interconnected and fixed by flange 4 securing member 5.
Vacuum diaphragm top tube connector 2 is vertical flanged (FLGD) iron pipe; Vacuum diaphragm lower connection pipe 3 is vertical flanged (FLGD) iron pipe or vertical flanged (FLGD) threeway iron pipe.
The diameter of vacuum diaphragm top tube connector 2 is identical with the caliber that draws water of vacuum jet pump; The diameter of the horizontal drainage pipeline of vacuum diaphragm lower connection pipe 3 is identical with the caliber that draws water of vacuum jet pump.
If when vacuum diaphragm and geotextiles do not need for 1 time to be connected with horizontal threeway iron pipe, only need vertical flanged (FLGD) iron pipe.Vacuum preloading technique goes out vacuum diaphragm pipeline connection technology, and whole linkage is made up of the upper and lower tube connector two parts of vacuum diaphragm, and whole vertical duct without the need to directly passing vacuum diaphragm, but realizes connecting by flanged plate, reaches the object of protection vacuum diaphragm.And select the caliber being applicable to vacuum pump drinking-water pipe as required.As being connected with level can selecting suitable iron pipe as required to threeway iron pipe with horizontal drainage pipeline.
