Abstract

PROBLEM TO BE SOLVED: To make it possible to provide an earth retaining structural body capable of follow the settlement of fill to displace it downward. SOLUTION: A built-up body 11 is so formed that a horizontal section 35 placed in an approximately horizontal state, first and second rise sections 28 and 29 bending from both ends of the horizontal section to rise upward and a recessed member 30 having an interlock section 15 formed in the first rise section 28 are connected with joint members 14 in the approximately horizontal direction at specific intervals. The built-up body 11 is filled with fill, and the other built-up body 11 is connected thereto through first and second interlocking members 12 and 13. Then, the first interlocking member 12 is inserted between the interlock section 15 and horizontal section 27, the second interlocking member 13 is such that the horizontal section is interlocked with the second rise section 29 from the front, and since a vertical part of an interlock section 31 is interlocked with the joint member 14 of the upper built-up body 11 from the rear A2, the displacement of the upper built-up body 11 downward is not regulated.

じる。When such an earth retaining structure 1 is arranged on a slope, the upper earth retaining structure 1 is stacked on the lower earth retaining structure 1. Therefore, when the earth and sand packed in the earth retaining structure 1 is displaced downward due to its own weight or compaction settlement, the upper earth retaining structure 1 is connected to the connecting material 5 and the end frame 6 of the lower earth retaining structure 1. Since the downward displacement is regulated by the above, a hollow space is formed between the upper part of the earth and sand packed in the lower earth retaining structure 1 and the lower end of the upper earth retaining structure 1, and thereby the upper space. There is a problem that the bottom of the earth retaining structure 1 is fully loaded with the upper filling sand and the upper earth and sand structure 1 is damaged.

沈下前と同様に使用することができる。The present invention has a rod-shaped horizontal portion arranged substantially horizontally and two rising portions which are bent and extend upward from both longitudinal end portions of the horizontal portion. A plurality of recessed members, each of which has a bent locking portion formed near at least one upper end of the rising portion, are housed in the assembly, and the assembly is connected to each other at substantially horizontal intervals. The filling material, the rod-shaped first locking member that is inserted into each locking portion of one rising portion of the assembly, and the filling material near the upper end of the other rising portion of the assembly are accommodated. A second locking member in the form of a rod arranged on the side opposite to the side, and another assembly is arranged above the assembly, and a horizontal portion of the upper assembly is used to connect the lower assembly to the lower assembly. The first locking member provided is supported from below and is lowered by the other rising portion of the upper assembly. Second locking member provided on the assembly is earth retaining structures, characterized in that locked. According to the present invention, the assembly includes a plurality of concave members spaced apart from each other, the concave members having two rising portions, and at least one rising portion having a locking portion formed near an upper end thereof. It In such an assembly, for example, one rising portion side is located below a slope or the like and the other rising portion is arranged apart from the slope, and the filling material is accommodated in the assembly. Next, the second locking member is arranged on the side of the other rising portion of the assembly opposite to the side where the filling material is accommodated, and another assembly is arranged above the assembly.
At this time, the second locking member is locked by the other rising portion of the upper assembly. Next, the first engaging member is inserted between the engaging portion formed on one rising portion of the lower assembly and the horizontal portion of the upper assembly to connect the respective assemblies, and The filling material is housed in the assembly. By stacking a plurality of assemblies along the slope in this manner, the earth retaining structure is built to prevent the slope from collapsing and collapsing. Since the first locking member, which is locked to the locking portion of the lower assembly, is locked from below by the horizontal portion of the assembly disposed above, the downward displacement of the upper assembly is restricted. Not connected to the lower assembly. Therefore, even if the filling material is displaced downward due to, for example, consolidation settlement or unequal settlement, the upper assembly can be displaced downward following the displacement of the filling material. Further, the other rising portion of the lower assembly is locked to the rising portion of the upper assembly by the second locking member, so that the displacement to the side opposite to the side in which the filling material is accommodated is prevented. Since it is regulated, it is possible to prevent the other rising portions from being displaced to the side opposite to the side in which the filling material is accommodated due to the weight of the filling material. Therefore, the filling material can be stably held in the assembly,
Safety is improved. Further, even if the filling of the filling material occurs, the filling material can be used in the same manner as before the settlement by supplementing the filling material according to the amount of subsidence.

In the excavation, as shown in FIG. 10, the backhoe 50 excavates a field board on which the earth retaining structure 10 is installed. If there is spring water that was not expected at the time of the survey at the back of the cut soil when excavating the foundation or cutting the soil, appropriate drainage is performed so that the soil retention structure is not affected according to the amount of water. Install facilities and take measures to drain the water outside the area. This is because the safety of all structures intended for retaining soil depends largely on the soil condition and water content on the back surface. If it rains during construction or if it is expected that it will rain, the embankment or filling material will be compacted and drainage will be applied. Depending on the amount of rainfall, it is necessary to take measures such as using sheets to prevent the material from penetrating into the filling material.

A locking portion is formed in the vicinity. In such an assembly, for example, one rising portion side is located below a slope or the like and the other rising portion is arranged apart from the slope, and the filling material is accommodated in the assembly. Next, the second locking member is arranged on the side of the other rising portion of the assembly opposite to the side where the filling material is accommodated, and another assembly is arranged above the assembly. At this time, the second locking member is locked by the other rising portion of the upper assembly.
Next, the first engaging member is inserted between the engaging portion formed on one rising portion of the lower assembly and the horizontal portion of the upper assembly to connect the respective assemblies, and The filling material is housed in the assembly. By stacking a plurality of assemblies along the slope in this manner, the earth retaining structure is built to prevent the slope from collapsing and collapsing.

It is connected to the lower assembly while its displacement is not restricted. Therefore, even if the filling material is displaced downward due to, for example, consolidation settlement or unequal settlement, the upper assembly can be displaced downward following the displacement of the filling material. Also,
The other rising portion of the lower assembly is locked to the rising portion of the upper assembly by the second locking member,
Since the displacement to the side opposite to the side where the filling material is stored is restricted, each rising part of the other should be displaced to the side opposite to the side where the filling material is stored due to the weight of the filling material. Is prevented. Therefore, the filling material can be stably held in the assembly, and the safety is improved. Further, even if the filling of the filling material occurs, the filling material can be used in the same manner as before the settlement by supplementing the filling material according to the amount of subsidence.
