Abstract

This invention is to provide a vertical drain pipe provided with fine holes having a substantially defined dimension, capable of avoiding use of a split cloth having fine filtering holes with an irregular dimension and effectuating specified secure filtering action. The vertical drain pipe is constituted of a non-chlorine based synthetic resin-made reinforcing core member 1 spirally wound up with a specified distance, an underground water filter membrane 2 of which the both side edges are adhered to the adjacent reinforcing core members 1, 1 and which closes the gap between the reinforcing core members 1, 1, an outer peripheral protection strip 3 made of non-chlorine based synthetic resin stuck onto the outer peripheral face of the reinforcing core member 1 through both side edges of the filter membrane 2. A tape-shaped raw material a that an oriented film made of a non-chlorine based resin raw material is cut in 0.3-3 mm width is woven in plain weave at every 0.3-3 mm distance together with the warp and the weft. Further, the filter membrane is formed of a first membrane 21 produced by heating the raw material with pressure and fusion-bonding its superposed intersection and a second membrane 22 formed out of non-chlorine based resin raw material-made non-woven cloth produced by inseparably adhering the first filter to the second filter. Moreover, the second membrane 22 is disposed at the outer peripheral face side.

Description

479092 V. Description of the invention (1) [Technical field to which the invention belongs is a water collecting pipe generally referred to as a vertical drain ^, which is buried in a state where it is pressurized from the ground and inserted into the ground at one end and is open on the ground at one end. And the water collecting pipe used for soil improvement. [Known technology] This type of vertical drainage pipe is used for saturated sandy soil sites that are judged to have a high possibility of liquefaction by special or specific soil improvers: For weak sites, use steel protection pipes and spray n The ground is pressed vertically into the ground, for example, 15m ~ 20m; the degree of fruit placement is as protruding from the ground with an opening, and soil is installed at the opening, ΐ! 2 ~ The vertical drain pipe used now-like " ： The outer sign of a spiral strength member formed by winding into a tree ^ 2 pieces of split fire cloth on the front and back formed by extending the film material into 20% of the film-like cloth for collecting water, and the two connection parts are joined to stand and outside, use this A three-layered water-collecting cloth is used to form a tube body, and the outer part of the binding part of the film-shaped cloth is joined by a reinforcing material that joins the two-cornered protrusions to form an integrated secondary product. : Underdrain drainage pipe used (for example, 'refer to Japanese Patent Laid-Open Publication No. 7_ the next two gazettes), also used as a vertical drainage pipe. 5 旒 [Problems to be solved by the invention] However, as the former is drained underground operation When the wall of the hole is dug, the vertical row of the structure is generated. ， The water collection of the patchwork is made of friction loss, and the special drain tube ’is in direct contact with the membrane-like cloth during insertion and drainage.

When it is difficult to maintain the outer periphery of the triangular protrusion-shaped cloth in the posture under the joint of the piece, it is necessary to insert the excavation hole wall into the ground, and the membrane-like cloth for water in the vertical drainage pipe is used to filter the cut hole on the bottom of the pipe for the purpose The reason is to solve the problem of soil which avoids the phenomenon of fine peeling of the used size. In addition, the strong material is self-forming, and the phenomenon of inserting the ground between the reinforcing cloths is a phenomenon. The messenger is a problem-type drainage tube which weakens due to the same shape and indeterminate soil and sand. The present invention provides a small indefinite shape. The strength structure of the specified shape and deformation of the inserting ground are relatively drain pipes. The patchwork is used to make membranes in the underground operation holes. Therefore, there are gaps. These two are convenient as countless sets on the set. Moreover, the problems of the present invention are precipitated, and the drain pipe can be a roughly determined constructor. However, it is easy to produce, because the supplementary surface of the intersecting section of the surrounding posture poses a large sudden excavation, which is sufficient to sink into the water-collecting film. As described above, the size of the forming material is not larger than the size to obtain the water-collecting effect. In response to problems such as Xi Zhili, the problem of filtering the large pores of the pores is to make it easy to make the ditch of the latter into a water collecting wall and the material of the drainage pipe is large and empty. This patchwork is made in the shape of patchwork. Therefore, the soil and sand inlet pipe has the above-mentioned vertical row patchwork and has a filtering effect.

It is' in the row and tap of the present invention, the pancreas is used to cut the plastic nails of the stretched film carefully, and "" is used with thread, and the uniform material w is used as the plain weave of the knitted fabric. The knitted fabric is pressurized and heated to form a plain weave to prevent expansion and contraction as a heart filter membrane. Weaving fabrics are used as heart filter membranes. N: The interlaced part is a membrane. Therefore, it has not only a knitted fabric and a non-woven fabric. At the same time, it has excellent straightness, which can effectively achieve a strong standing posture under the pressure of soil pressure. In addition, it is easy to expand and deform when the posture of being jealous and inserting into the ground is not easy to expand and contract. The small hole maintains the filtration of the soil and sand, and has the function of maintaining the surname ^ 'so' that can perform predetermined filtering and quasi-long-term water collection effect.
