摘要： PROBLEM TO BE SOLVED: To provide a pipe device capable of joining and separating unit pipes speedily to reduce labor and costs. SOLUTION: Unit pipes Z composed by assembling an inner pipe 10 and an outer pipe 20 coaxially are sequentially connected in the longitudinal direction. In each unit pipe Z to be connected, the inner pipe 10 and the outer pipe 20 are connected so as to be immobile at a position in the peripheral direction, male screws having the same pitch are formed in end parts to be connected of the inner pipe 10 and the outer pipe 20 of the unit pipe Z on one side, respectively, and female screws having the same pitch as the above-mentioned pitch are formed in end parts to be connected of the inner pipe 10 and the outer pipe 20 of the unit pipe Z on the other side, respectively. When the unit pipe Z on one side and the unit pipe Z on the other side are connected, the male screw of the inner pipe 10 of the unit pipe Z on one side and the female screw of the inner pipe 10 of the unit pipe Z on the other side are mutually screw- fitted, and the male screw of the outer pipe 20 of the unit pipe Z on one side and the female screw of the outer pipe 20 of the unit pipe Z on the other side are mutually screw-fitted.

摘要： PROBLEM TO BE SOLVED: To suppress the discharge of grout and cutting mud. SOLUTION: The high-pressure grout and compressed air are injected via an injection pipe 80 in a state wherein the injection pipe 80 is inserted into ground g along an approximately horizontal direction, and the grout is agitated for mixing in order to create a consolidated body 100 having a diameter whose center is taken as the injection pipe 80. In this case, a mud discharge pipe 70 is arranged along the upper-end position of the diameter of land formation in such a manner as to make the inside of the ground g communicate with the outside thereof, and the flow rate of mud discharge through the pipe 70 is measured. On the basis of a normal control upper limit and a normal control lower limit as to the mud-discharge flow rate, which are determined according to an injection rate, the flow rate of the mud discharge through the pipe 70 is decreased when the measured flow rate is taken as the upper limit or above, and the flow rate of the mud discharge is increased when the measured flow rate is taken as the lower limit or below.

摘要： PROBLEM TO BE SOLVED: To provide a ground improvement device and its improvement method capable of surely making changeover of connection between an opening window and the inside of an internal pipe in a ground insertion pipe such as sludge removal pipe, improved rod or the like. SOLUTION: The opening window 52a is formed in the front end of an external pipe 50, the inside of the internal pipe 40 and opening window 52a are constituted in a connectable manner in the front end of the internal pipe 40, in a state to fix the position of the external pipe, the internal pipe 40 can be moved in the direction of an axial-center by external force acting on the internal pipe 40 in the base of the insertion pipe, the connection between the opening window 50a and inside of the internal pipe 40 is prevented in a first position of the movement, and the improvement device is so constituted that the connection between the opening window 52a and inside of the internal pipe 40 is executed in a second position.

摘要： PROBLEM TO BE SOLVED: To quickly and accurately manage the completed amount of excavation and filling work, etc., by displaying the GPS three-dimensional coordinates of a plurality of construction machines working in a construction field on the screen of a device provided at one location with a simple constitution. SOLUTION: The GPS three-dimensional coordinate data of a plurality of construction machines moving in a construction field obtained by performing GPS measurement are transmitted by radio from mobile stations 4-6 mounted on the machines. A fixed station 2 also transmits its GPS three-dimensional coordinate data by radio. A central management station 1 receives the coordinate data. The position computing device for mobile station of the station 1 calculates the three-dimensional coordinates of the machines and station 2 on an already known map on which the location of the fixed station 2 is plotted from the three-dimensional coordinate data and the three-dimensional coordinates (latitude, longitude, and altitude) of the station 2 on the map by performing kinematic survey with a GPS interferometer system and simultaneously displays the three-dimensional coordinates of the locations of the moved mobile stations 4-6 on the map on a screen.
