Description

  The present invention relates to a continuous wall body using an H-shaped member as a sheet pile and a construction method thereof.

  The wall and foundation continuous wall body is constructed of steel sheet piles, and as such steel sheet piles, U-shaped steel sheet piles with fitting parts at both ends are generally known. A steel wall is constructed by engaging a large number of steel sheet piles consisting of a web and flanges provided at both ends in the width direction and joints fixed at the width direction ends of the flanges. For example, Patent Literature 1) and a female joint of a fitting joint on one side edge of a flange of a normal rolled H-shaped steel, and a male joint on the other side edge are positioned inward from the outer surface of the flange and welded. A joint that can be fitted to each other is welded to each of the end faces of both side edges of the flange of a rolled steel sheet pile (for example, Patent Document 2) and a normal rolled H-shaped steel, and each of the joints is a center of fitting. Is a steel sheet pile (for example, patent) 3) and a plurality of ordinary rolled H-shaped steels whose height difference is within the range that can be welded at the flange part, but the flange side edges of each other are welded together and the flanges project on both sides Steel which is formed in a box shape and welded and joined with a female joint of a fitting joint on one of both side edges sandwiching the welded joint of the flange, and a male joint on the other, located inward of the outer surface of the flange. A guide plate projecting outward is provided in the longitudinal direction on the opposing inner surface of a sheet pile (for example, Patent Document 4) or a parallel flange of H-shaped steel, and the guide plate of one H-shaped pile and the other H There is a construction method (for example, Patent Document 5) in which a plurality of H-shaped piles are continuously driven on the ground so that the flange inner surfaces of the shaped piles slide on each other.

In addition, a method has been proposed in which H-shaped steel is used as a sheet pile and a solidified material is filled in a space formed by the flange portion of the H-shaped steel. For example, many steel sheet piles with male joints and steel sheet piles with female joints are used. Is constructed with the male joint member inserted in the female joint member, and the time-curable material is inserted from the tremy tube inserted between the adjacent steel sheet piles, between the adjacent steel sheet piles, in the female joint member and the steel sheet pile. Underground continuous wall construction method (for example, Patent Document 6) that fills and fills the gap between the steel and the groove at the same time, or a structural wall (for example, patent) filled with concrete between each steel shell and the formwork or buried formwork Reference 7), steel element (for example, Patent Document 8) in which a time-hardening filler is filled in a gap between joints engaged with each other, and a steel sheet pile joint using a steel material such as an H-shaped steel sheet pile Bituminous / rubber adhesive, asphalt on the inner surface of the closing part An adhesive such as an acid primer is applied, and the space in the joint portion of the joint member is a bitumen material such as an asphalt mixture as a water stop material via the adhesive layer, clay, mortar, concrete, clay mortar, There is a steel sheet pile joint (for example, Patent Document 9) filled with a water stop material such as a viscous material.
Japanese Patent Laid-Open No. 6-2646692 JP 7-279162 A JP 7-279163 A JP 7-48831 A JP-A-4-203114 Japanese Patent Laid-Open No. 5-272131 JP-A-6-299540 JP-A-6-316923 JP 2001-348862 A

  Since the steel sheet pile of the above-mentioned patent document 1 is provided with a joint at the end of the flange, the material cost of the steel sheet pile itself is expensive, and is not a general-purpose product, unlike those using ordinary rolled H-section steel. Therefore, it is difficult to divert other than forming a continuous wall body. Furthermore, in order to increase the rigidity in terms of structure, it is necessary to increase the thickness of the steel sheet pile itself or to apply a member that is one rank higher. Moreover, a special member is required to construct the curved portion of the continuous wall.

  In addition, since the dimension between the joints is fixed by the flange width, if it is attempted to secure the required amount obtained by designing the wall body parallel direction dimension of the continuous wall body, it is wasteful because it must be set excessively. Furthermore, even when constructing, if it is intended to close in the middle of the continuous wall, highly precise construction management is required, which is not easy.

  On the other hand, in the steel sheet piles of Patent Documents 2 to 4, since a normal rolled H-section steel is used, the material cost is low, but the structure is joined by a fitting joint protruding from the end of the flange. There is a problem that the strength of the joint portion is lower than that of the portion. Moreover, since the steel sheet pile adjacent also in patent document 5 is joined by the guide plate thinner than a flange, the intensity | strength of a junction part falls from a flange part. On the other hand, if a guide plate having the same thickness as the flange is used, the strength of the joint portion is improved, but the product cost is increased.

  Moreover, in the wall body of patent documents 6-9, although the rigidity of a continuous wall body is raised by filling the solidified material in the H-section steel connected with the joint, or water-stopping is raised, the said literature The problem described in 1 has not been solved.

  And the steel sheet pile using H-shaped steel in this way has the subject which should be improved on a cost side or a structure, and the conventional general U-shaped steel sheet pile is used universally, but U-shaped steel sheet pile Has the following problems.

    When used for temporary structures such as retaining walls, the rigidity is lower than H-shaped steel, and the earth pressure and water pressure applied to the wall body increase due to deep excavation, etc. It takes time to erection the support work, and it takes time to construct the structure. Moreover, in the construction work of the structure, the support work becomes an obstacle, the setting of reinforcing bars and formwork cannot be performed, and the construction of the structure must be performed separately at the support work place, which is not preferable in terms of structure. Arise. In other words, since it is necessary to proceed with the construction of the structure for each range that avoids the supporting work, which is a cut beam, the construction of the structure will be constructed at every interval of the supporting work. This is disadvantageous in terms of structural strength and seismic performance. In addition, as a structure, for example, in the construction of bridge piers, there is a limitation on the construction period of completing the construction within the drought period, and the construction method that repeats work for each support construction interval is inferior in workability and difficult in terms of construction period. There is.

    And in order to shorten the work period and reduce the number of joints and improve the seismic performance of the structure, it is possible to widen the vertical interval of the support work or to eliminate the support work. A retaining wall with high rigidity is required, and the retaining wall having a conventional structure is expensive and inferior in economic efficiency.

  SUMMARY OF THE INVENTION The present invention is intended to solve such problems, and an object thereof is to provide a continuous wall body that is easy to construct, inexpensive, and has excellent structural rigidity, and a construction method thereof.

  According to the configuration of the first aspect, the rigidity of the wall body can be easily increased or decreased by changing the overlapping length of the flange portions. In addition, a curved wall can be easily created by changing the insertion lengths of the flange portions on both sides. And when the flange part of an adjacent H-shaped member is piled up, the rigidity of a wall body increases. Thereby, the supporting member used for a wall body may be few compared with the past, and it is easy to make the self-supporting earth retaining wall without a supporting work.

  In such a structure combining H-shaped members, since the solidified material is filled between the flanges, the rigidity of the entire wall can be further increased, and it can be applied to retaining walls at large depths where high lateral pressure acts. It becomes possible. In addition, when a cement system is used as the solidifying material, the solidifying material is a compression material, and has a basic structure that can withstand an overload. Furthermore, since the inside is filled with the solidifying material, the water stoppage of the entire wall body is improved. Further, the filled solidification material fixes the positions of the H-shaped members in both the direction perpendicular to the wall and the direction parallel to the wall, and ensures stability during an earthquake.

  Also, by overlapping the flange parts of adjacent H-shaped members and filling with solidified material, the wall thickness can be reduced, and the amount of excavated soil, concrete amount, etc. for building a continuous wall body using H-shaped members can be reduced. Get smaller. Furthermore, the required land area is small.

  Moreover, according to the structure of Claim 2, the shift | offset | difference of flange parts is changed and the H-shaped member is arrange | positioned, and the transition to the overlapping of flange parts can be made easy. Further, the rigidity of the wall surface can be easily increased or decreased. In addition, a curved wall can be easily created by changing the separation length between the flange portions on both sides.

  In such a structure in which H-shaped members are combined, since the solidified material is filled between the flange portion and the substantially extended line thereof, the rigidity of the entire wall body can be further increased, and at a large depth where high side pressure acts. It can be applied to the retaining wall. In addition, when a cement system is used as the solidifying material, the solidifying material is a compression material, and has a basic structure that can withstand an overload. Furthermore, since the inside is filled with the solidifying material, the water stoppage of the entire wall body is improved. Further, the filled solidified material fixes the positions of the H-shaped members in both the direction perpendicular to the wall and the direction parallel to the wall, and ensures stability during an earthquake or the like.

  Moreover, according to the structure of Claim 3, since the engaging joint member was used, it becomes a guide at the time of construction, and an attachment position is decided. Furthermore, the filling range of the solidifying material is limited between the flange portion and the joint member, so that the solidified material is ensured.

  Moreover, according to the structure of Claim 4, since the engaging joint member was used, it becomes a guide at the time of construction, and an attachment position is decided. Furthermore, the filling range of the solidifying material is limited between the flange portion and the joint member, so that the solidified material is ensured.

  Moreover, according to the structure of Claim 5, by using concrete or mortar for a solidification material, rigidity increases more reliably and the utilization range as a synthetic member spreads. In addition, the water stop performance is excellent.

  Moreover, according to the structure of Claim 6, water stop performance and rigidity are ensured by using cement or soil cement for a solidification material. Moreover, if a method of drilling and injecting the solidified material is used, a composite structure can be made at an arbitrary location.

  Moreover, according to the structure of Claim 7, since an H-shaped member can peel from a solidification material, extraction of an H-shaped member becomes easy and diversion becomes possible.

  Moreover, according to the structure of Claim 8, since the solidification material is filled only in the location where high rigidity and water stop are required, the range of design selection is expanded. In addition, by filling the solidified material with necessary sections in the length direction of the wall, high rigidity and water stop can be partially secured, and a cheaper wall can be pursued.

  Further, according to the configuration of claim 9, a continuous wall body having high rigidity and water-stopping property can be constructed. At this time, the installation process of the H-shaped member and the filling process of the solidifying material are separated. A wall can be easily constructed. Since the solidified material is filled between the flange portions using a fluid (powdered material, liquid material, etc.) capable of following the shape as the solidified material, no waste is generated in the material of the solidified material.

  Moreover, according to the structure of Claim 10, since there exists an excavation process which discharges the soil between the flange parts of an H-shaped member, filling with concrete and mortar becomes reliable. Moreover, since excavation is performed between the flange portions, the external ground is not damaged.

  Further, according to the structure of the eleventh aspect, in order to insert the injection pipe after drilling, even if there is soil between the flange portions of the H-shaped member, cement or the like is injected into any place, and cement or soil cement It is possible to solidify the solidified material alone or to obtain a bonded structure with soil. Further, since the solidifying material is injected between the flange portions of the H-shaped member, there is little leakage to the outside, and the external ground is not damaged.

  Moreover, according to the structure of Claim 12, since an H-shaped member is installed by striking or press-fitting, the construction machine can cope with a general-purpose and simple one compared with a method of forming a groove and installing it. Moreover, it is an inexpensive method without damaging the natural ground and without needing to hold the natural ground with a stabilizing solution.

  Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below do not limit the contents of the present invention described in the claims. In addition, all of the configurations described below are not necessarily essential requirements of the present invention. In each embodiment, by adopting a new continuous wall body different from the conventional one and its construction method fence, an unprecedented continuous wall body and its construction method are obtained, and the continuous wall body and its construction method are described respectively. To do.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show Embodiment 1 of the present invention, and the continuous wall 1 is used as a vertical wall, such as a retaining wall, retaining wall, revetment wall, foundation, pier, impermeable wall, or as a horizontal wall. , Used for protective roofs and culverts (box culverts, etc.), and may be used as girders such as bridges.

  FIG. 2 shows an example in which the continuous wall 1 is used as the foundation of a pier 101. For the H-shaped member 2 forming the continuous wall 1, an ordinary rolled H-shaped steel material is preferably used, and the web portion 3 has flange portions 4, 4 on both sides. Further, the H-shaped members 2 and 2 adjacent in the wall body parallel direction have the same shape, and as shown in FIG. 1, the inner and outer surfaces of the flange portions 4 and 4 of the plurality of adjacent H-shaped members 2 and 2 The continuous wall 1 is constructed by forming an overlapping portion 5 where the two are overlapped. That is, the flange portions 4 and 4 of the adjacent H-shaped members 2 and 2 are shifted in the thickness direction (the direction perpendicular to the wall) of the flange portions 4 and 4 different from the same plane and overlapped.

  The space S between the flange portions 4 and 4 on both sides is filled with a solidified material 6. The solidifying material 6 may be a fluid material that can be solidified over time. As a first preferred example, concrete or mortar, which is a cement-based solidified material, is used. As a second preferred example, cement is used. Cement and soil cement, which are system binding materials, are raised. In the second preferred example, the ground material can be solidified by filling and injecting cement, cement milk or cement paste into the ground material such as earth and sand between the flange portions 4 and 4. Further, as the solidifying material, the soil or sand in the space S may be removed with air or the like and replaced with cement alone or soil cement.

  By filling the solidified material 6 between the flange portions 4 and 4 in this way, the water stoppage of the continuous wall body 1 is improved. In addition, the continuous wall 1 has a composite structure of an H-shaped member 2 and a solidified material 6. If the H-shaped member 2 made of H-shaped steel is used, the tensile stress is improved. This improves the compressive stress. Further, the composite structure increases the resistance to shear stress and bending stress with respect to a horizontal load, and increases the resistance to compressive stress with respect to a vertical load.

  Furthermore, the filled solidified material 6 prevents the H-shaped members 2 and 2 from being displaced from each other, and the H-shaped members 2 and 2 are fixed in the direction perpendicular to the wall body and in the direction parallel to the wall body. In addition, even when a joint member is provided, it is not necessary to strengthen the joint member, and in particular, the H-shaped member 2 that does not contact the support work such as the rising of the continuous wall body 1 or a cut beam. It is possible to prevent displacement in the direction perpendicular to the wall.

  In the continuous wall body 1, the section filled with the solidifying material 6 is not limited to the entire wall body 1, but if the solidifying material 6 is filled in the lower part of the wall body 1, the earth retaining wall has a high earth pressure and water pressure. The resistance at the bottom can be increased. If the end of the wall 1 is filled with the solidifying material 6, it can be reinforced against the shearing force of the beam. Further, at the starting and reaching pits for propulsion, the wall body 1 is filled with the solidified material 6, and leakage can be prevented by cutting the mirror when starting and reaching the shield machine. In the case of water leakage, after the wall body 1 is constructed, the solidifying material 6 may be filled corresponding to the location where water leakage has occurred.

  Moreover, it is good to respond | correspond by making a hole in the web part 3 of the H-shaped member 2 so that the solidification material 6 may be filled easily.

  In addition, after the use of the retaining wall, the H-shaped member 2 is pulled out and applied to the surface in contact with the solidifying material 6 in order to be divertable. That is, the release material 7 is applied to both surfaces of the web portion 3 of the H-shaped member 2 and the inner surfaces of the flange portions 4 and 4. As the release material 7, a bitumen material (asphalt), a primer, a plastic material, a rubber material, a concrete release material, or the like is used, as long as it improves the release property from the solidified material 6 from the outer surface of the H-shaped member 2 itself. Various types are used, and application methods such as brush application or spraying are used as the application method.

  Next, the construction procedure of the continuous wall 1 will be described. In the installation process, the H-shaped member 2 is hammered into the ground G, or is inserted into the ground G to a predetermined depth, or a groove is excavated and formed at the construction location of the continuous wall 1 to form the H-shaped member. Put 2 in. The groove is formed by a continuous excavation groove by a continuous underground wall excavator or a circular hole of a drill type auger excavator, and when excavating, the groove is stabilized by using a stable liquid such as muddy water. Keep the stability of.

  In the filling process, when concrete or cement is used for the solidified material 6, the H-shaped member 2 is driven or pressed into a predetermined depth, and then the earth and sand between the flange portions 4 and 4 are excavated to the inside. Placing solidifying material 6 such as concrete or mortar. When cement or soil cement is used for the solidifying material 6, the H-shaped member 2 is driven or press-fitted and inserted to a predetermined depth, and then injected between the flange portions 4 and 4, as shown in FIG. An excavation hole 8 into which the pipe 9 can be inserted is formed, and an injection pipe 9 is inserted into the excavation hole 8, and cement is injected and injected from the lower end side of the injection pipe 9. It is solidified by injecting into the ground material. Alternatively, when a continuous underground wall excavator is used, the H-shaped member 2 is inserted into the groove while excavating the groove, and the solidified material 6 is filled between the flange portions 4 and 4.

  Further, as a method for installing the H-shaped member 2, the above-described method by hitting or press-fitting does not damage the ground G, and unnecessary excavation becomes unnecessary. As the construction machine at this time, a relatively versatile machine such as a pile hammer or a piler can be used. On the other hand, in the method of building the H-shaped member 2 after excavating the groove, as described above, the method of building the H-shaped member 2 by forming the continuous excavation surface by the groove excavator and the formation of the circular hole by the auger excavation are formed. For example, a method of building the H-shaped member 2 is used.

  Further, as an excavation method between the flange portions 4 and 4 of the H-shaped member 2, when excavating the entire cross section of the flange portions 4 and 4 from the ground, excavation with a jet such as a water jet or an air jet, excavation with a grab bucket, auger Excavation with an excavator is used.

  In the method of injecting cement as the solidifying material 6, it can be injected as cement, cement milk, or cement paste. Note that a resin-based solidifying material may be used for the solidifying material 6.

As a method for injecting the solidified material 6, the excavation hole 8 is formed by boring as described above, the injection tube 9 is inserted into the excavation hole 8, and the cement milk that is the solidification material 6 is injected into the ground material from the injection tube 9. In addition to the osmotic injection method of osmotic injection, high-pressure injection injection method that replaces cement while injecting air or water with high pressure from the injection tube 9 and discharging the air or water with the lift-up force of these air or water, or injection The pipe 9 is provided with a stirring blade (not shown) and provided with a rotating means for rotating the injection pipe 9. The injection pipe 9 is rotated by the rotating means while injecting the solidified material 6, and the ground material and the solidified material 6 are rotated by the stirring blade. Can be used to form a soil cement.
.

  And since the flange parts 4 and 4 are divided | segmented by the web part 3 with respect to the wall body parallel direction of the wall body 1, it becomes possible to selectively improve a required location, the location which leaked, and start The solidification material 6 may be filled in the arrival wellhead, and the construction can be simply performed by simply injecting the solidification material 6 using the injection pipe 9.

  In addition, as shown in FIG. 3, when the continuous wall body 1 is curved in a plane, the overlapping portion 5 on the inner side in the bending direction may be made larger than the overlapping portion 5 on the outer side of the curvature.

  Thus, in this embodiment, corresponding to claim 1, a continuous wall body 1 using the H-shaped member 2 as a sheet pile, and the flange portions 4, 4 of the adjacent H-shaped members 2, 2 are overlapped. In addition, since the solidified material 6 is filled between the flange portions 4 and 4 on both sides, the rigidity of the wall body 1 can be easily increased or decreased by changing the overlapping length of the flange portions 4 and 4. . Further, the curved wall 1 can be easily created by changing the insertion lengths of the flange portions 4 and 4 on both sides. And when the flange parts 4 and 4 of the adjacent H-shaped members 2 and 2 are overlapped, the rigidity of the wall body 1 is increased, and thereby, the support member used for the wall body 1 can be reduced as compared with the prior art. This makes it easier to create self-supporting retaining walls without support.

  In such a structure in which the H-shaped members 2 and 2 are combined, since the solidified material 6 is filled between the flange portions 4 and 4, the rigidity of the entire wall body 1 can be further increased, and a large lateral pressure acts. Applicable to retaining walls at depth. Moreover, if a cement system is used for the solidifying material 6, the solidifying material 6 is a compression material, and has a basic structure that can withstand an overload. Furthermore, since the inside is filled with the solidification material 6, the water-stopping property of the whole wall body 1 improves. Further, the filled solidified material 6 fixes the positions of the H-shaped members 2 and 2 both in the direction perpendicular to the wall and in the direction parallel to the wall, so that stability during an earthquake is ensured. Further, by overlapping the flange portions 4 and 4 of the adjacent H-shaped members 2 and 2 and filling the solidified material 6, the wall thickness can be reduced, and the continuous wall body 1 using the H-shaped members 2 and 2A is constructed. As a result, the amount of excavated soil, concrete amount, and the like is reduced, and the required land area is reduced.

  In this way, in this embodiment, corresponding to claim 5, since the solidified material 6 is concrete or mortar, the rigidity is more reliably increased and the range of use as a composite member is expanded. Moreover, it becomes the thing excellent in the water stop performance.

  In this way, in this embodiment, the solidifying material 6 is cement or soil cement corresponding to the sixth aspect, so that water-stopping performance and rigidity are ensured, and the solidifying material 6 is drilled. If an injection method is used, a synthetic structure can be made at an arbitrary position.

  In this way, in this embodiment, corresponding to claim 7, since the H-shaped member can be peeled from the solidified material by applying the solidifying material release material 7 to the inner surfaces of the flange portions 4, 4, The H-shaped member 2 can be easily pulled out and can be diverted.

  Further, in this embodiment, in correspondence with the eighth aspect, the solidified material 6 is filled only in a portion where high rigidity and water stop are required because the solidified material 6 and the non-filled portion are provided. This broadens the range of design choices. Further, by filling the solidified material in the necessary sections in the wall body parallel direction or the H-shaped member length direction of the wall body 1, high rigidity and water stop can be partially secured, and a less expensive wall body 1 is pursued. it can.

  In this way, in this embodiment, corresponding to claim 9, the continuous wall 1 is formed by using the H-shaped member 2 as a sheet pile and overlapping the flange portions 4, 4 of the adjacent H-shaped members 2, 2. Since the construction method comprises the installation step of installing the H-shaped member 2 and the filling step of filling the solidified material between the flange portions on both sides, the continuous wall body 1 having high rigidity and water blocking ability can be constructed, At this time, since the installation process of the H-shaped member 2 and the filling process of the solidifying material 6 are separated, the wall body 1 having an arbitrary shape can be easily constructed. Since the solidified material 6 is filled with the solidified material between the flange portions 4 and 4 using a fluid capable of following the shape, the material of the solidified material 6 is not wasted.

  In this way, in this embodiment, corresponding to claim 10, the solidifying material 6 is concrete or mortar, and the filling step includes the step of excavating between the flange portions 4 and 4, and the setting of the solidifying material 6. Therefore, since there is an excavation process for discharging the soil between the flange portions 4 and 4 of the H-shaped member 2, the filling of concrete and mortar is ensured. Moreover, since excavation is performed between the flange parts 4 and 4, an external ground is not damaged.

  Thus, in this embodiment, corresponding to claim 11, the solidifying material 6 is cement or soil cement, and the filling step includes a step of inserting the injection tube 9 and a step of injecting the solidifying material 6. Therefore, even if there is soil between the flange portions 4 and 4 of the H-shaped members 2 and 2, cement or the like is injected into an arbitrary place to solidify the cement or soil cement solidifying material 6 alone, To obtain a combined structure. Further, since the solidified material 6 is injected between the flange portions 4 and 4 of the H-shaped member 2, there is little leakage to the outside, and the external ground is not damaged.

  In this way, in this embodiment, corresponding to claim 12, since the installation process is performed by hitting or press-fitting the H-shaped member 2, the construction machine is more versatile than the method of forming a groove and installing it. It is an inexpensive method that does not damage the ground and does not need to be pressed with a stabilizing solution.

  Further, as an effect of the embodiment, since the H-shaped members 2 and 2A are rolled H-shaped steel, the material acquisition is easy and inexpensive. Moreover, when the rolled H-section steel with versatility is pulled out, it can be diverted to a support material and a girder in addition to the wall body.

  In the construction method of the continuous wall body, the present embodiment describes the case where the flange portions of the H-shaped member are overlapped with each other, but the extension line of the flange portion of the H-shaped member and the flange of the adjacent H-shaped member The same construction method can be used when the parts are overlapped.

  4-5 shows Example 2 of this invention, attaches | subjects the same code | symbol to the same part as the said Example 1, and abbreviate | omits the detailed description, This example shows the continuous wall body 1 in FIG. This is applied to the retaining wall. As shown in the figure, when constructing the foundation of a structure such as a pier or a building in the ground, it is continuous as a retaining wall around the construction point K for constructing the foundation. The wall bodies 1, 1, 1, 1 are constructed, and the flank 11 made of H-shaped steel or the like is arranged on the inner surfaces of the opposed continuous wall bodies 1, 1, and the continuous wall body 1 is passed through these bulges 11. , 1 has a support 12 as a beam. Moreover, as shown by hatching in FIG. 5, the continuous wall 1 is filled with a solidifying material 6 on the lower side where the earth pressure and the water pressure are high. In addition, since the continuous wall 1 of this example is a temporary structure which can be removed if the construction location K is backfilled after constructing the foundation, the H-shaped member 2 can be pulled out and reused.

  In the continuous wall body 1 as such a retaining wall, the rigidity is improved by the structure of the overlapping portion 5 and the solidified material 6 filled between the flange portions 4, 4, so that the retaining wall becomes self-supporting or the interval of the support 12. Since the reinforcing bar joint and the concrete joint of the structure provided at the construction location K can be omitted or reduced, the quality of the structure can be improved and the workability can be improved.

  In this embodiment, the flanges 4 and 4 of the adjacent H-shaped members 2 and 2 are overlapped with each other, and the space S is filled with the solidifying material 6, thereby increasing the rigidity of the wall body 1. Compared to, it is possible to use fewer support members for the wall body 1 and it is easier to make a self-supporting retaining wall without supporting work. By using this retaining wall, the construction period of the structure is shortened and the number of joints is reduced. Thus, the seismic performance of the structure can be improved, and a highly reliable structure can be constructed.

  7 to 12 show a fourth embodiment of the present invention. The same reference numerals are given to the same portions as those of the above-mentioned embodiments, and detailed description thereof will be omitted. FIG. An example used for a wall, FIG. 9 shows an example used for a water-impervious wall, which resists horizontal loads such as earth pressure and groundwater pressure. The continuous wall 1 uses H-shaped members 2 and 2A having different sizes as sheet piles. These H-shaped members 2 and 2A are preferably made of ordinary rolled H-shaped steel, and have flange portions 4, 4, 4A and 4A on both sides of the web portions 3 and 3A. The flanges 4A and 4A of the small H-shaped member 2A are used in combination between the inner surfaces of the parts 4 and 4, and the flanges of the adjacent large H-shaped member 2 in the continuous wall 1 are used. Between the inner surfaces of the portions 4 and 4, the overlapping portion 5 of the flange portion into which the flange portions 4A and 4A of the small H-shaped member 2A are inserted is formed. In this way, the flange portions 4 and 4 of the large H-shaped member 2 and the flange portions 4A and 4A of the small H-shaped member 2A are arranged in the thickness direction of the flange portions 4 and 4A different from the same plane (at right angles to the wall). The H-shaped members 2 and 2A adjacent to each other are restrained against the force in the direction perpendicular to the wall to the continuous wall 1 by forming the overlapping portion 5. Further, by filling the space S between the flange portions 4, 4, 4A, 4A of the adjacent H-shaped members 2, 2A with the solidifying material 6, the rigidity of the entire wall body 1 can be further increased. And the continuous wall 1 which is the earth retaining wall of FIG. 8 is filled with the solidification material 6 on the lower side where the earth pressure is high, and the continuous wall 1 which is the water blocking wall of FIG. The solidified material 6 is filled up to the height of the continuous wall 1 in FIG.

  In the construction, the H-shaped members 2 and 2A are struck into the ground G, and are inserted or pressed into a predetermined depth, or a groove is excavated and formed at the construction location of the continuous wall 1. The shape members 2 and 2A are stood up. The groove is formed by a continuous excavation groove by a continuous underground wall excavator or a circular hole of a drill type auger excavator, and a stable liquid such as muddy water can be used for the stability of the groove during excavation.

  Rolled H-section steel is used for the H-shaped members 2 and 2A. However, as long as the web sections 3 and 3A and the flange sections 4, 4, 4A and 4A are provided, in addition to the rolled H-section steel, rolled I Shaped steel may be used, and plastics or the like other than steel may be used. Also, as shown in FIG. 10, a plurality of H-shaped members 2 and 2A may be integrated, and in the same figure, flange portions 4, 4, 4A and 4A are welded and integrated, or FIG. As shown, it may have a shape in which a plurality of web portions 3 are provided.

  Thus, in the continuous wall body 1 using the H-shaped members 2 and 2A, the rigidity of the wall body 1 is improved by the overlapping portion 5 of the flange portions 4 and 4A. Further, as shown in FIG. When the H-shaped members 2 and 2A are installed, even when the dimension of the last mating portion is different from the other portions, it can be easily handled by adjusting the dimension of the overlapping portion 5. In FIG. Since the interval between the H-shaped members 2 and 2 in the mating portion is narrower than the other, it can be dealt with by enlarging the overlapping portion 5 with the H-shaped member 2A inserted between them. Therefore, when the retaining wall is formed with a conventional U-shaped or H-shaped sheet pile, the dimension between the joints of the sheet pile is constant, so the dimension cannot be adjusted at the last mating part, and the accuracy is increased. It is necessary to set the placement position, and if the last sheet pile is forcibly placed, the sheet pile will crack, or in some cases, it was necessary to pull out multiple sheet piles and place it again. Then, the dimension adjustment of the last mating part can be simply performed by the dimension of the overlapping part 5 of the flange parts 2 and 2A. In addition, when using a sheet pile with a fixed dimension between the joints, the dimensions and the like are designed according to the dimension of the sheet pile. For example, a place where only one-half of the sheet pile is required for the design is a sheet pile. As a result, an excessive part is generated by design, and this also affects the amount of soil for excavation and backfilling and the amount of bottom slab concrete. On the other hand, in the present embodiment, since the continuous wall body 1 corresponding to the design dimension can be constructed, the above-described waste can be eliminated.

Thus, rigidity and water stoppage can be improved.

  FIG. 35 shows a twenty-first embodiment of the present invention. The same reference numerals are given to the same portions as those of the above-mentioned embodiments, and detailed description thereof will be omitted. In this example, adjacent H-shaped members are connected to each other. A joint member is shown, and there is no overlapping portion between the H-shaped members 2 and 2A, and the extension lines (not shown) of the flange portions 4 and 4 and the flange portions 4A and 4A of the adjacent H-shaped member 2A are overlapped. That is, the flange portions 4 and 4 and the flange portions 4A and 4A are not aligned in a straight line, but are shifted in the width direction (perpendicular to the wall body) and separated in the wall body parallel direction. The flange portions 4A and 4A are inserted between the extension lines. Then, the inside of one piece of the L-shaped steel 51 as a joint member is attached to the inner surface of the end of the flange portion 4A of the small H-shaped member 2A, and the other piece 51A side is connected to the flange portion 4A from the end of the flange portion 4A. Projects outward in the length direction. Further, the grooved steel 52 as the inner fitting portion is attached to the inner surface on the end side of the flange portion 4 of the large H-shaped member 2, and the outer surface side of the grooved steel 52 as the joint member is attached. The other piece 51A of the shaped steel 51 is configured to be able to be engaged. In this way, the grooved steel 52 and the L-shaped steel 51, which are joint members, project from the flanges 4 and 4A of the H-shaped members 2 and 2A, and the flanges 4 and 4A of the adjacent H-shaped members 2 and 2A are thick. It is shifted in the vertical direction (the direction perpendicular to the wall).

  Therefore, in the construction, as shown in FIG. 35, the adjacent flange portions 4 and 4A are shifted in the thickness direction, and the flange portions 4A and 4A are aligned between the extension lines of the flange portions 4 and 4, The H-shaped members 2 and 2A are installed so that the other piece 51A of the L-shaped steel 51 is inserted into the grooved steel 52, and the overlapping portion 5A in which the grooved steel 52 and the L-shaped steel 51 overlap each other. And the dimension of the overlapping portion 5A can be adjusted by the length of the channel steel 52. Then, the solidified material 6 is filled in the space S between the flange portions 4, 4, 4 </ b> A, 4 </ b> A, the grooved steel 52, 52, and the L-shaped steel 51, 51.

  Thus, in the present embodiment, corresponding to claim 2, the continuous wall body 1 using the H-shaped members 2 and 2A as a sheet pile, and adjacent to the extension line of the flange portion 4 of the H-shaped member 2 Since the flange portion 4A of the shape member 2A is overlapped and the solidified material 6 is filled between the flange portions 4, 4, 4A, 4A on both sides and its extended line, the spacing between the flange portions 4, 4A is changed. Thus, the rigidity of the wall body 1 can be easily increased or decreased. And when the joint member and flange part or joint member of adjacent H-shaped members 2 and 2A are piled up, the rigidity of the wall body 1 increases. Further, the separation between the H-shaped members 2 and 2A is not fixed and can be set arbitrarily, so that the continuous wall body 1 having the dimension parallel to the wall body as designed can be easily formed. Moreover, when installing, even if the predetermined position of the separate H-shaped members 2 and 2A is inferior in accuracy, it can be easily adjusted and installed. Furthermore, the transition to the overlapping of the flange portions 4 and 4A can be facilitated.

  In this way, in this embodiment, corresponding to claim 4, the H-shaped members 2 and 2A are provided with the grooved steel 52 and L-shaped as a joint member for engaging the adjacent H-shaped members 2 and 2A with each other. Since the steel 51 is provided on the flange portions 4 and 4A, the joint member is fitted and serves as a guide during construction, and the mounting position is determined.

  In such a structure in which the H-shaped members 2 and 2 are combined, the solidified material 6 is filled between the flange portions 4, 4, 4A and 4A and the groove-shaped steels 52 and 52 and the L-shaped steels 51 and 51 as the joint members. Therefore, the rigidity of the wall body 1 as a whole can be further increased, and the wall body 1 can be applied to a retaining wall at a large depth where a high lateral pressure acts. Moreover, if a cement system is used for the solidifying material 6, the solidifying material 6 is a compression material, and has a basic structure that can withstand an overload. Furthermore, since the inside is filled with the solidification material 6, the water-stopping property of the whole wall body 1 improves. Further, the filled solid material 6 fixes the positions of the H-shaped members 2 and 2A in both the direction perpendicular to the wall body and the direction parallel to the wall body, thereby ensuring stability during an earthquake. Further, by overlapping the flange portions 4 and 4A of the adjacent H-shaped members 2 and 2A and filling the solidified material 6, the wall thickness can be reduced, and the continuous wall body 1 using the H-shaped members 2 and 2A is constructed. As a result, the amount of excavated soil, concrete amount, and the like is reduced, and the required land area is reduced. Further, by arranging the grooved steel 52 and the L-shaped steel 51, which are joint members, by changing the distance between the flange portions 4 and 4A on both sides, a curved wall can be easily created.

  In this embodiment, both flange portions 4A and 4A of the other H-shaped member 2 are inserted between the extended lines of both flange portions 4 and 4 of the adjacent one H-shaped member 2. One of the flange portions 4A, 4A of the other H-shaped member 2A may be inserted between the extended lines of the flange portions 4, 4 of one H-shaped member 2, and adjacent H-shaped members are connected to each other. The same shape may be used, rolled H-section steel may be used for the H-shaped members 2 and 2A, and rolled steel materials such as L-shaped steel, groove-shaped steel, round steel, and flat steel may be used for the joint members.

  In addition, in the construction method of the continuous wall 1, the H-shaped members 2 and 2A are used as sheet piles, and the extension line of the flange portion 4 of the H-shaped member 2 and the flange portion 4A of the adjacent H-shaped member 2A are overlapped. It is a construction method of the wall body 1 and includes an installation process of installing the H-shaped members 2 and 2A, and a filling process of filling the solidified material 6 between the flange portions 2 and 2A on both sides and its extended line. The continuous wall body 1 having high rigidity and water-stopping property can be constructed. At this time, the installation process of the H-shaped members 2 and 2A and the filling process of the solidifying material 6 are separated. Can be built. Since a fluid capable of following the shape is used as the solidifying material 6 and the solidifying material 6 is filled between the flange portions 4 and 4A, the material of the solidifying material 6 is not wasted. Further, the solidifying material 6 is concrete or mortar, and the filling step includes a step of excavating between the flange portions 4 and 4A and a substantially extended line thereof, and a step of placing the solidifying material 6. Since there is an excavation process for discharging the soil between the two flange portions 4 and 4A, filling of concrete and mortar is ensured. Moreover, since excavation is performed between the flange parts 4 and 4A, an external ground is not damaged. Further, the solidifying material 6 is cement or soil cement, and the filling step includes a step of inserting the injection tube 9 and a step of injecting the solidifying material 6, so that the flange portions 4 and 4A of the H-shaped members 2 and 2A. Even if there is soil between the extended lines, cement or the like can be injected into an arbitrary location to solidify the cement or soil cement solidifying material 6 alone, or to obtain a bonded structure with soil or the like. In addition, since the solidified material 6 is injected between the flange portions 4 and 4A of the H-shaped members 2 and 2A, there is little leakage to the outside and the external ground is not damaged. In addition, the installation process is performed by hitting or press-fitting the H-shaped members 2 and 2A, so that the construction machine can be handled with a general-purpose and simpler tool than the method of forming a groove and damaging the ground. Therefore, there is no need to hold the ground with a stabilizing solution, and this is an inexpensive method.
