摘要： PURPOSE:To increase the service life of an anchor by a method wherein bearing plate attached to the tip of a tensile steel material is protected by a tip cap filled with a rust-proof oil, a tubular load-bearing material is contacted with a free-length sheath, and a grout is packed into the outside of them for covering. CONSTITUTION:A bearing plate 2 is fixed to the tip of a tensile steel material 1, a tip cap 9 is attached to the plate 2 with an oil-tight structure, and a rust- proof oil 10 is packed into the cap 9 for rust-proofing treatment of the fitting portion of the plate 2. A tubular load-bearing material 3 is contacted with the plate 2 and they are joined by welding with a water-tight structure and also water-tightly welded with a free-length sheath 4 having an enough length to reach a structural body 6. The joint with the body 6 is made fittable through a damper 8 in a sliding manner. They are inserted into an anchor pit 14 and a grout 5 is packed into the outside. The construction work can thus be easily performed and the life of the anchor can be lengthened sufficiently.

摘要： PURPOSE:To avoid the leak loss of a grout injected under the ground by overlappingly injecting the grout into soft ground. CONSTITUTION:An injection tube is penetrated to a given depth into a soft ground 8 in an area to be improved, and while injecting a gelled solidifying agent 7, the injection tube 1 is pulled up by a given distance. The injection tube 1 is then repenetrated into the solidifying agent 7 injected and then pulled up, during which gelled solidifying agent 7' is again injected into the preceding solidifying agent 7 injected. The solidifying agent 7' injected later expands inside the preceding solidifying agent 7, and thereby the surrounding eroded soil layer 8 is further compressed and the outside face of the preceding solidifying agent 7 is almost molded into a designed shape.
摘要翻译：目的：避免通过将灌浆重新注入软土而注入地下的灌浆泄漏损失。构成：将注射管穿透到要改进的区域中的软土地面8中，并且在注入胶凝固化剂7的同时，将注射管1向上拉一定距离。然后将注射管1再渗透入注射的固化剂7中，然后拉起，在此期间将凝胶化固化剂7'再次注入注入的先前固化剂7中。随后注入的凝固剂7'在前面的凝固剂7的内部扩展，从而使周围的侵蚀土层8被进一步压缩，并且前面的固化剂7的外表面几乎被模制成设计形状。

摘要： PURPOSE:To perform a complete implanting of grout into a ground, by implanting grout as dispersion of particles of suspension type grout is promoted by ultrasonic waves. CONSTITUTION:Grout, mixed by a grout mixer 1, is implanted into a ground T from an implanting tube 4 through an implanting line 3 by a grout pump 2. In the case of implanting, an implanting takes place as dispersion of particles of suspension is promoted by ultrasonic waves of about 10,000-40,000Hz generated by an ultrasonic generator 6.

摘要： PURPOSE:To prevent the slackening and falling of planting materials sprayed on the upper part of a water-impermeable slope by dividing the water-impermeable slope into contour lined sections by using horizontal cement mortar beams inserted with iron bars having a high bonding strength. CONSTITUTION:Fibrous composite mats 3 are laid in a contour lined manner on a water-impermeable slope 1 by means of concrete nails 4. Then, anchor bolts 5 are driven at equal intervals along the lower ends of the mats 3 in such a way that the heads of the anchor bolts 5 are exposed about 15cm or more from the mats 3. Then, the heads of the anchor bolts 5 are connected by iron bars 6 and on the upside of the part, drain pipes 7 are inserted at equal intervals into the mats 3. Then, cement mortar is sprayed on the drain pipes 7, the iron bars 6, and anchor bolts 5 in such a way as to cover all of them. And so, a planting material 10 consisting of soil, fertilizer, seeds, etc, is sprayed on the slope 1 divided by cross beams 2 on cotrour lines.
