Description
Technical Field
The invention relates to the technical field of soft soil foundation treatment, in particular to a connecting device of a straight-line vacuum preloading vacuum tube and a plastic drain board.
Background
Since the proposal and application of the technology of vacuum preloading in the eighties of the last century, vacuum preloading has been one of the main effective methods for treating soft soil foundations through years of practical application and development. The direct-discharge vacuum preloading method is widely applied to foundation treatment of the dredger fill site in coastal areas.
The quality of the treatment effect of the direct drainage type vacuum preloading mainly depends on the application, transmission and maintenance of the vacuum degree, wherein the application of the vacuum degree depends on the suction force effectively applied by a unit area vacuum pump (namely, the effective power provided by the unit area vacuum pump), the maintenance of the vacuum degree depends on the sealing effect of a vacuum film and a field, the transmission of the vacuum degree mainly depends on the smoothness of a vacuum pipeline below the film (namely, the vacuum degree in a vacuum pipe) and the suction force of a vertical plastic drainage plate (namely, the vacuum degree in the drainage plate), and the vacuum degree in the plastic drainage plate depends on the connection quality (namely, the vacuum degree loss degree) of the vacuum pipeline and the plastic drainage plate to a great extent. The connection of the vacuum line to the plastic drain board is therefore of great importance.
The invention patent number ZL201220324973.7 discloses a vacuum transverse drainage joint device, which comprises a water passing plate, a butterfly joint and a plastic drainage plate, wherein two ends of the water passing pipe are connected with outlets at two ends of the butterfly joint, and two wings of the butterfly joint are directly connected with the drainage plate.
Although this method is capable of connecting drain boards and vacuum wire hoses, it has several disadvantages:
1) In the butterfly joint, the extension length of the side wing is 20cm, the thickness of the side wing is only 1cm, the length and the thickness are relatively large, the overall rigidity is relatively small, the flange is easy to break, the destruction rate is relatively high, and the side wing is not beneficial to recycling.
2) In this patent butterfly joint, flank extension length is 20cm, and its thickness is 1cm only, and when plastics drain bar inserted, the space that remains in the flank is less, and the vacuum degree transmission of rigid plastic pipe and butterfly joint is passed through the rectangular hole of 10 x 80mm of both sides only simultaneously, because vacuum pre-compaction time is generally longer (is greater than 90 days), and transmission channel is easily blocked by debris such as silt, and the transmission effect of vacuum degree will be discounted greatly.
3) According to the patent, each butterfly joint is fixed with the plastic drain board through 6 shooting nails, so that the shooting nails in the field are large in use amount, a large number of shooting nails are required to be carried by constructors, the butterfly joints are easy to be left in the field, and if the butterfly joints are left in the field, vacuum films can be possibly pierced in the later stage, the vacuum degree is influenced, and the foundation treatment effect is influenced.
