摘要： PURPOSE:To obtain a construction method, enabling to construct continuous wall at depth of even 100m at underground, and to remove the inter-lock members after the concrete being hardened, while providing the improved efficiency of excavating works. CONSTITUTION:After completing excavation, steel partitioning plates 1 in the excavated groove A at the tunnel head with interval as required, are arranged, while inter-lock members 3 being contacted with the ground at excavated tunnel head are set, the jack 5 in between the partitioning plates 1 and inter-lock members 3 is installed to support the partitioning plates 1 to protect itself from concrete pressure. Following the above procedures, concrete 7 is deposited at the excavated groove A, after the concrete 7 is hardened, the inter-lock members 3 are removed by releasing the jack 5, and the succeeding excavation work is started.

摘要： PURPOSE:To enable an easy installation of a caison in the prevention of inclination of the caison, by sinking the caison down on the ground below a caison's cutter which is previously uniformed by the use of sand or gravel piles. CONSTITUTION:The ground, where a caison 2 is sunk and is below a cutter 3, is first replaced with sand piles or gravel piles 1. When the caison 2 is laid down on the sand pile 1 group, and excavating is repeatedly performed at the inside of the caison 2 and the part of the sand pile 1 being below the cutter 3, and thus, the caison 2 is sunk for installation. Excavating below the cutter 3 is performed gradually by the use of high-pressure jet 4 and the like in order to avoid a unbalancing sinking. On the other hand, a sand compaction process and so on, which is adopted for installation of sand piles and sand drain, can be considered as the method of installing the sand piles 1.

摘要： PURPOSE:To make adhesion of concrete better and improve water sealability by a method wherein concerte is filled after a surface of a partitioning plate wall for a continuous wall is cleaned by a wall surface cleaning machine to remove adhered substances on a construction joint portion thereof. CONSTITUTION:A wall constituting unit body 1 is established in a digged hole 6, thereafter, concrete 7 is filled during replacing wall surface stabilizing liquid. Next, a digged hold 9 of a next order is digged and adhesive substances such as bentonite cake or the like adhered to a partitioning steel plate are cleaned and removed by a wall surface cleaning machine 10. The cleaning machine 10 is moved up-and-down by a winding device such as a crane or the like along the partitioning steel plate 2 and removes the bentonite cake by blades thereof and cleans the wall surface of the partitioning steel plate 2 with wire brush thereof. In one step of this cleaning, the steel pate is cut by a cutter provided on a supporting arm of an engaging member because a slit 3 is covered with a thin steel plate 16. Subsequently, a water sealing steel plate 19 is inserted into a guide groove 5 after the cleaning is finished. Successively, the wall constituting unit body of the next process is established in the digged hole, thereafter, the concrete is filled.

摘要： PURPOSE:To obtain the subject method wherein guide steel frames act simultaneously as interclocking pipe, cut-off wall and joint, easy and simple in construction, avoid of deviation in excavating alignment, owing to the action of the guides, easy in mutual engagement and fixing works among guide steel frames and most suited for construction work at deep level. CONSTITUTION:In the preparation of underground continuous walls by utilizing muddy water, the guiding steel frame 1 having the partition steel plate 3 with many projecting steel reinforcing rod for jointing 6 on its surface between two water- stopping steel plates equipped with the engagement 5 on one end and the guide 4 on the other is used as the inter-locking material. This guiding steel frame 1 is connected continuously in digging of unit grooves and the concreate 7 is filled in between the water-stopping steel plates 2.
