摘要： PROBLEM TO BE SOLVED: To provide an extension method of the existing tunnel capable of economically making widening in the case total extension length is long or even in the case a section is small. SOLUTION: The extension method includes an upper half widening section 20 and a lower half widening section 22, and a widening tunnel 12 including the whole section of the existing tunnel 10 inside thereof is constructed. When the widening tunnel 12 is constructed, a simple protector 24 having an inverted recess section for ensuring the traffic of a vehicle is installed at the inside of a lining layer 14, the excavation of the upper half widening section 20 is carried out before the lower half widening section 22, and a mobile working platform 26 is installed on a bench 28 formed by the preceding excavation in a movable manner along the direction of the axis of the existing tunnel 10. The excavation of the upper half widening section 20 and the fracture removal of side walls 18 of the lining layer 14 are carried out by work from the mobile working platform 26. The excavation of the lower half widening section 22 and the fracture removal of the side walls 18 of the lining layer 14 are carried out by work on roadbeds on the sides of the side walls 18.

摘要： PROBLEM TO BE SOLVED: To provide an extension method of the existing tunnel making use of a mobile working platform capable of economically making widening in the case a total extension length is long or even in the case a section is small. SOLUTION: The extension method includes an upper half widening section 20 and a lower half widening section 22, and a widening tunnel 12 including the whole section of the existing tunnel 10 inside thereof is constructed. When the widening tunnel 12 is constructed, a simple protector 24 having an inverted recess section for ensuring the traffic of a vehicle is installed at the inside of a lining layer 14 of the existing tunnel 10, and the portal mobile working platform 26 capable of coating the outer circumference of the protector 24 is installed along the direction of the axis of the existing tunnel 10 in a movable manner. The excavation of the upper half widening section 20 and the fracture removal of the ceiling section 16 of the lining layer 14 are carried out by the excavator 36 mounted on the mobile working platform 26. The excavation of the lower half widening section 22 and the fracture removal of side walls 18 of the lining layer 14 are carried out by excavators 27 through work on the roadbeds on the sides of the mobile working platform 26.

摘要： PROBLEM TO BE SOLVED: To prevent a batholith from swelling without carrying out artificial work even when the pumping of underground water from a deep well is stopped due to failure of a pump. SOLUTION: When a water permeation layer 5 deposits through a non- permeation layer 3 beneath the natural ground 1, a pit 7 reaching the inside of the non-permeation layer 3 is built by digging the natural ground 1, after the water level of the underground water W in the permeation layer 5 is lowered by draining the underground water W from a deep well 19, the natural ground 1 is dug, a bore 11 is formed by carrying out boring up to the inside of the permeation layer 5 from the digging face in the middle of the digging of the natural ground 1. And then a fiber bolt 13 is installed in the bore 11, a water permeation backfill material 15 is filled in the bore 11 so that underground water W may be discharged upward through the bore 11. And then the digging of the natural ground 1 is resumed to dig a digging face reaching the inside of the non-permeation layer 3.

摘要： PURPOSE:To have good water seal function by affixing a cloth impregnated in advance with a hardening agent to the inner wall surface of an underground storage tank before the hardening takes place, and then allowing the agent to harden. CONSTITUTION:A cloth 2 impregnated in advance with a hardening agent is before hardening affixed to the inner wall surface of an underground storage tank 1, constructed by excavation, using an adhesive, etc., and then the hardening shall take place. The hardening agent shall be of type having a high hardening speed, easy-to-handle property, water solubility and high hardening rigidity, which is used in gypsum for medical care. Cloth 2 may be affixed in multiple plies according to the design strength of the timbering work 2. This provides requisite water seal function and facilitates mechanization of the affixing operations.

摘要： PROBLEM TO BE SOLVED: To increase the strength of a reinforcing section sufficiently, and to inhibit the displacement of a peripheral bedrock at a small value at the time of tunnelling by inserting a rod for high-pressure injection from the internal surface of a pilot heading in the bedrock up to specified depth and forming an improved body within an approximately tunnelling predetermined range by injecting cement milk at high pressure. SOLUTION: The pilot heading 12 is excavated in a bedrock 11 prior to the excavation of a tunnel 10, a plurality of rods 13 for high-pressure injection are inserted at regular intervals until the rods 13 reach sections corresponding to the side section and upper section of the tunnel 10 from the internal surface of the pilot heading 12, and cement milk 14 is injected at high pressure in the radial direction of the tunnel from nozzle holes at the front end sections of the rods 13 for high-pressure injection. The rods 13 for high-pressure injection are extracted while being rotated under the state, in which cement milk 14 is jetted. Accordingly, the bedrock 11 is excavated at the pressure of cement milk 14 while excavated materials and cement milk 14 are mixed and cured, and a discoidal soil mortar pile is formed centering around the inserting sections of the high-pressure injection rods 13.

摘要： PURPOSE:To simplify execution of works by impregnating a textile with a hardening agent in advance, winding this textile before hardening round a degraded concrete pillar, and allowing it to harden. CONSTITUTION:A textile 2 impregnated in advance with a hardening agent and made flexible is wound round a concrete pillar or beam 1 with crack initiation or surface degradation, and thus the degraded part is reinforced. After the hardening agent of textile 2 hardens, the rigidity of the degraded surface of the pillar or beam 1 increases to ensure that the pillar or beam 1 is strengthened. Thus reinforcing works can be done shortly.
