Description

  The present invention relates to a construction method for a structure.

  It is conceivable to construct a structure on the embankment as a countermeasure against tsunami and liquefaction. For example, Patent Documents 1 and 2 are known as banking construction methods.

JP-A-4-254606 JP 2008-031722 A

  In the structure as described above, since the structure is constructed on the embankment after embedding a predetermined height on the ground, the construction period may be prolonged.

  In view of the above facts, an object of the present invention is to shorten the construction period of a structure constructed on a bank.

  The structure construction method according to claim 1 is parallel to the structure construction process, a structure construction process for constructing a structure on the structure, and a structure construction process for constructing a plurality of structures on the ground. And a banking step of banking under the structure.

  According to the construction method of the structure according to claim 1, in the strut construction step, a plurality of struts are constructed on the ground. Next, in the structure building process, a structure is built on the support. At this time, embankment is performed under the structure in parallel with the structure construction step.

  Thus, in this invention, in a support | pillar construction process, a structure construction process and a banking process can be performed in parallel by constructing a plurality of support | pillars on the ground. Therefore, compared with the case where a structure is constructed on the embankment after embankment on the ground, the construction period can be shortened.

  The structure construction method according to claim 2 is the structure construction method according to claim 1, wherein the embedding step is a beam as a part of the structure between the struts in the structure construction step. This is done after erection.

  According to the structure construction method of the second aspect, in the structure construction step, a beam as a part of the structure is installed between the columns. Thereby, since the frame is formed by the support and the beam, the support becomes more stable. Thereafter, in the embankment process, embankment is performed under the structure.

  As described above, in the present invention, since the embankment process is performed after the frame is formed on the ground in the structure construction process, the inclination of the column accompanying the embankment is suppressed.

  Moreover, until the floor is constructed, earth and sand can be dropped from between the beams in a plan view and can be filled under the structure. Therefore, the workability of embankment improves.

  The structure construction method according to claim 3 is the structure construction method according to claim 1 or 2, wherein the embedding step is a step of constructing the structure body between the struts in the structure construction step. After building the floor as a part.

  According to the construction method of the structure according to claim 3, the floor is constructed between the columns in the structure construction step. Thereby, a support | pillar becomes more stable. Thereafter, in the embankment process, embankment is performed under the structure.

  As described above, in the present invention, since the embankment process is performed after the floor is constructed between the struts in the structure construction process, the inclination of the struts accompanying the embankment is suppressed.

  Further, by constructing a floor between struts prior to the embankment process and using it as a work floor or a material storage place, the workability of the structure constructed on the strut is improved.

  The construction method of the structure according to claim 4 is the construction method of the structure according to any one of claims 1 to 3, wherein, in the strut construction step, a pile whose upper portion projects from the ground. Build and form at least a portion of the post with the pile.

  According to the construction method of the structure according to claim 4, in the strut construction step, a pile whose upper part protrudes from the ground is constructed, and at least a part of the strut is formed by this pile.

  Here, since the embankment is formed by raising the earth and sand, the support strength for supporting the pile driver and the like is likely to be weaker than the ground (original ground). Therefore, when hitting a pile from the top of the embankment, for example, it is necessary to improve the embankment to ensure the support strength of the pile driver or the like. Moreover, when a pile is driven from above the embankment, the amount of excavation and soil removal increases according to the height of the embankment.

  On the other hand, in the present invention, since the pile is constructed on the ground prior to the embankment process, the above-described improvement of the embankment becomes unnecessary. In addition, excavation and soil removal associated with the construction of piles is reduced. Therefore, the workability of the pile is improved.

  As described above, according to the construction method for a structure according to the present invention, the construction period of the structure constructed on the embankment can be shortened.

  Hereinafter, a construction method for a structure according to an embodiment of the present invention will be described with reference to the drawings.

[First embodiment]
First, a construction method for a structure according to the first embodiment will be described.

  In the first embodiment, the structure 10 shown in FIG. The structure 10 includes a foundation 60 constructed on the embankment 50 and a multi-layer structure 30 constructed on the foundation 60. Hereinafter, each construction process of the structure 10 is demonstrated concretely.

  First, the column construction process will be described. As shown in FIG. 1 (A), in the strut construction process, first, a pile 14 is constructed on the ground (original ground) 12. Specifically, a plurality of piles 14 are driven into the ground 12 by a pile driving machine 16 or the like. At this time, the upper portion 14U of the pile 14 is protruded upward from the ground 12. Thereby, the lower part of the support | pillar 20 (refer FIG.1 (B)) mentioned later is formed by the upper part 14U of the pile 14. FIG.

  The pile 14 is, for example, a steel pile or a concrete pile. The pile 14 may be a ready-made pile or a cast-in-place pile. Further, the pile 14 may be a friction pile or a support pile.

  Next, as shown in FIG. 1B, a temporary column 18 is erected on the head of each pile 14, and the pile 14 and the column 18 are joined. Thereby, the support | pillar 20 is formed of the upper part 14U and the pillar 18 of the pile 14. FIG. The height H of this support | pillar 20 shall be more than the height (construction height) T (refer FIG. 2 (A)) of the embankment 50 mentioned later (H> = T).

  In addition, the pillar 18 comprises the pillar of the first floor F1 of the structure 30 (refer FIG. 3 (B)), and is made into the permanent pillar 28 by post-construction. The permanent column 28 is, for example, a steel structure, a reinforced concrete structure, a steel reinforced concrete structure, or the like.

  Next, the structure construction process will be described. In the structure building process, a beam 22 is installed between column heads of adjacent columns 20 to build a frame 24 and a floor 26 (see FIG. 2B) is built on the beam 22.

  The beam 22 is a steel structure, a reinforced concrete structure, a steel reinforced concrete structure, or the like. The floor 26 is made of reinforced concrete. Further, the floor 26 may be a flat slab, in which case the beam 22 is omitted.

  Subsequently, as shown in FIG. 2A, the second floor F2 of the structure 30 is constructed on the support column 20 in the structure construction step. Specifically, the pillars 32 are erected on the respective pillars 20, and the frame 34 is constructed between the pillars 32 to construct the frame 36. Further, as shown in FIG. 2B, a floor 38 is constructed on the beam 34.

  At this time, for example, the scaffold bracket 40 is attached to the head of the pillar 18 on the first floor F1 of the structure 30 and the scaffold 42 is secured on the scaffold bracket 40. Thereby, the scaffold 42 for the second floor F2 of the structure 30 can be secured while securing a construction space for the embankment 50 described later below the structure 30. In addition, the kind of scaffold can be changed suitably.

  Here, in this embodiment, the embankment process is performed in parallel with the structure construction process. Specifically, as shown in FIG. 2B, after the floor 26 of the second floor F2 of the structure 30 is constructed, a banking process is performed in parallel with the remaining construction of the structure 30.

  In the embankment process, the earth and sand are compacted on the ground 12 below the structure 30, and the substantially trapezoidal embankment 50 is constructed in an elevational view. The height T (distance from the ground 12 to the lower end of the foundation 60) of the embankment 50 is set near the head of the pile 14, and the upper portion 14U of the pile 14 is embedded in the embankment 50. Further, a peripheral wall portion 52 surrounding the foundation 60 is formed on the outer peripheral portion of the upper surface 50U of the embankment 50. The embankment 50 may be mixed with an improving material (solidifying material) as necessary.

  Here, “performing the embankment process in parallel with the structure construction process” is a concept including performing the structure construction process and the embankment process partially in parallel. In the present embodiment, the embankment process is started after the structure construction process is started. However, any of the structure construction process and the embankment process may be started first.

  Subsequently, as shown in FIG. 3A, the upper floor FU of the structure 30 is sequentially constructed in the foundation construction step. At this time, the basic construction process is performed in parallel with the structure construction process. In this foundation construction process, the foundation 60 is constructed on the upper surface 50U of the embankment 50. The foundation 60 is configured by, for example, a plurality of foundation beams 62 joined in a lattice shape in plan view, and is supported by each pile 14. The foundation 60 may be constituted by a foundation slab or the like.

  Next, as shown in FIG. 3B, concrete is placed around the pillar 18 of the first floor F <b> 1 of the structure 30 to construct a main pillar 28. Thereby, the structure 10 is constructed. In addition, you may construct | assemble the permanent pillar 28 previously in the support | pillar construction process mentioned above.

  Next, effects of the first embodiment will be described.

  First, in order to clarify the effect of this embodiment, the construction method of the structure which concerns on a comparative example is demonstrated.

  In the construction method according to the comparative example, first, the embankment 102 is constructed on the ground 12 as shown in FIG. Next, as shown in FIG. 4 (B), a pile 14 is driven onto the ground 12 from above the embankment 102 by a pile driving machine 16 or the like. Next, as shown in FIG. 4C, the upper surface 102U of the embankment 102 is dug down to form a foundation recess 102A.

  Next, as shown in FIG. 5A, a foundation 106 composed of the foundation beam 104 and the like is constructed in the foundation recess 102A. Next, as shown in FIGS. 5B and 5C, the first floor F <b> 1, the second floor F <b> 2, and the upper floor FU are sequentially constructed on the foundation 106. Thereby, the structure 100 is constructed.

  As described above, in the construction method of the structure according to the comparative example, in order to construct the structure 100 on the bank 102 after the bank 102 having the predetermined height T (FIG. 4B) is formed on the ground 12, The construction period is prolonged.

  On the other hand, in this embodiment, as described above, the plurality of struts 20 are constructed on the ground 12 in the strut construction step. Next, in the structure construction step, a beam 22 as a part of the structure 30 is installed between the columns 20 and a floor 26 is constructed on the beam 22.

  Subsequently, in the structure construction step, the second floor F2 and the upper floor FU of the structure 30 are sequentially constructed on the support column 20. At this time, the embankment process is performed in parallel with the structure construction process. That is, the embankment 50 is constructed under the structure 30 in parallel with the construction of the structure 30.

  Thus, in this embodiment, the structure construction process and the embankment process can be performed in parallel by constructing the plurality of struts 20 on the ground 12 prior to the embankment process. Therefore, in this embodiment, as shown in the process chart shown in FIG. 6, the construction period can be shortened compared to the comparative example in which the embankment 102 is built on the ground 12 and then the structure 110 is constructed on the embankment 102. . Incidentally, since the construction process of the second floor F2 can be started early, the entire construction period can be shortened.

  In the present embodiment, the frame 24 is constructed prior to the embankment process, and the floor 26 is constructed on the beam 22. Thereby, since the scaffold for constructing the beam 22 and the floor 26 can be temporarily installed on the ground 12, the workability of the beam 22 and the floor 26 is improved.

  Furthermore, the floor 26 can also serve as a work floor or a material storage place when the second floor F2 and the upper floor FU of the structure 30 are constructed. Therefore, the workability of the second floor F2 and the upper floor FU of the structure 30 is improved.

  In addition, by constructing the frame 24 prior to the embankment process, the support column 20 is more stable (the rigidity as the structure 30 is improved). Therefore, the inclination etc. of the support | pillar 20 accompanying the embankment 50 are suppressed. Furthermore, in this embodiment, the floor 26 is also constructed between the columns 20 prior to the embankment process. Thereby, since the support | pillar 20 is further stabilized, the inclination etc. of the support | pillar 20 accompanying the embankment 50 are further suppressed.

  Moreover, in this embodiment, in the support | pillar construction process, the pile 14 from which the upper part 14U protrudes from the ground 12 is constructed, and at least a part of the support column 20 is formed by the pile 14.

  Here, since the embankment 50 is formed by raising earth and sand, the support strength for supporting the pile driving machine 16 and the like is likely to be weak. Therefore, for example, in the case of hitting the pile 14 from the top of the embankment 102 as in the comparative example shown in FIG. 4B, for example, it is necessary to improve the embankment 102 to ensure the support strength of the pile driver or the like. There is. Further, when a pile is hit from above the embankment 102, the amount of excavation and soil removal increases according to the height T of the embankment 102. In other words, once earthed earth and sand is discharged.

  On the other hand, in this embodiment, since the pile 14 is constructed on the ground 12 prior to the embankment process, the above-described improvement of the embankment 50 is not necessary. Furthermore, the amount of excavation and soil removal associated with the construction of the pile 14 is also reduced. Therefore, the workability of the pile 14 is improved.

  Furthermore, in the comparative example, since the pile driving machine 16 is installed on the upper surface 102U of the embankment 102, it is necessary to level the upper surface 102U of the embankment 102 once. Thereafter, as shown in FIG. 4C, the upper surface 102U of the embankment 102 is dug down to form a foundation recess 102A. Therefore, the amount of excavation and earth removal of the embankment 102 further increases.

  On the other hand, in this embodiment, after hitting the pile 14 in the ground 12, the embankment 50 is constructed. That is, in this embodiment, since the pile driving machine 16 is not installed on the upper surface 50U of the embankment 50, the upper surface 50U of the embankment 50 does not need to be leveled for the pile driving machine 16, and the embankment process 50 performs the embankment 50. A peripheral wall portion 52 surrounding the foundation 60 has already been formed on the outer peripheral portion of the upper surface 50U. Therefore, unlike the above-described comparative example, it is not necessary to dig up the upper surface 50U of the embankment 50 to form a concave portion for foundation, so that the amount of excavation and soil removal is reduced.

[Modification]
Next, a modification of the first embodiment will be described.

  As shown in FIG. 7A, adjacent piles 14 may be reinforced by reinforcing beams 56.

  Specifically, first, the reinforcing beam 56 is installed on the adjacent pile 14 in the strut construction process. Thereby, the bending rigidity of the pile 14 is improved. In this state, as shown in FIG. 7B, the temporary pillars 18 are erected on the heads of the respective piles 14 to form the pillars 20.

  Next, as shown in FIG. 8A, in the structure building process, the second floor F2 of the structure 30 is built on the support column 20, and in the banking process parallel to this, the embankment 50 is placed under the structure 30. To do. At this time, the reinforcing beam 56 is embedded in the embankment 50.

  Next, as shown in FIG. 8B, in the structure construction step, the upper floors FU of the structure 30 are sequentially constructed. Furthermore, the foundation 60 is constructed on the upper surface of the embankment 50 in the foundation construction process in parallel with the structure construction process. Then, the main pillar 28 of the first floor F1 of the structure 30 is constructed.

  In this way, in the strut construction process, by connecting the adjacent piles 14 with the reinforcing beams 56, the bending rigidity of the struts 20 can be increased. Therefore, since the support | pillar 20 becomes more stable, the inclination of the support | pillar 20 accompanying the embankment 50 can be suppressed.

  Moreover, although the bending rigidity of the support | pillar 20 can also be improved by enlarging the pile diameter of the pile 14, when the pile diameter is enlarged, there is a possibility that the amount of excavation increases. On the other hand, in this embodiment, since the adjacent pile 14 is connected with the reinforcement beam 56, the increase in the amount of excavation can be suppressed.

  The reinforcing beam 56 may be a temporary member (a member having a strength capable of maintaining the bending rigidity of the support column 20) until the foundation 60 is constructed, or may be a permanent member.

  Next, in the first embodiment, the example in which the embankment process is started after the beams 22 and the floor 26 are constructed between the adjacent struts 20 in the structure constructing process is shown, but the present invention is not limited thereto. The embankment process may begin before building the beam 22 and floor 26 between adjacent struts 20.

  Specifically, as shown in FIG. 9A, after the strut 20 is constructed in the strut construction process, a part of the embankment 50 is constructed on the ground 12 in the embankment process. Next, as shown in FIG. 9B, in the structure building process, the beam 22 is installed between the adjacent columns 20, and the remaining part of the bank 50 is built in the banking process parallel thereto.

  Thus, the embankment process can be started even before the beam 22 and the floor 26 are constructed between the adjacent columns 20. Also in this case, the work period can be shortened as in the first embodiment.

  In the structure building process, it is possible to start the embankment process after the beam 22 is installed between the adjacent columns 20 and before the floor 26 is built. In this case, since the frame 24 is constructed by the support 20 and the beam 22, the support 20 is more stable. Therefore, the inclination etc. of the support | pillar 20 accompanying the embankment 50 can be suppressed.

  Further, until the floor 26 is constructed on the beam 22, the embankment 50 can be constructed on the ground 12 by dropping earth and sand from between the beam 22 and the beam 22 in a plan view. Therefore, the workability of the embankment 50 is improved.

  In this way, in the structure building process, when the embankment process is performed after the beam 22 is installed between the adjacent columns 20 and before the floor 26 is built, the inclination of the column 20 is suppressed, The workability of the embankment 50 can be improved. In addition, for example, it is also possible to construct the embankment 50 on the ground 12 without forming a part of the floor 26, that is, by forming an opening in a part of the floor 26 and dropping earth and sand from the opening. .

  Next, a downward frictional force (negative friction) is generated in the upper portion 14U of the pile 14 embedded in the embankment 50 as the embedding of the embankment 50 is consolidated. Similarly, a downward frictional force is generated in the lower portion of the pile 14 embedded in the ground 12 due to the consolidation settlement of the ground 12 or the like. When this frictional force adversely affects the support performance of the pile 14, for example, it is desirable to perform friction cutting on the pile 14 and cut the vertical edges of the pile 14 and the embankment 50 and the ground 12.

  Examples of the friction cut include a sheet-like covering material that covers the outer peripheral surface of the pile 14 and a coating agent that is applied to the outer peripheral surface of the pile 14. The friction cut can be provided on at least one of the upper portion 14U and the lower portion 14L of the pile 14. However, when the pile 14 is a friction pile, it is desirable to apply a friction cut only to the upper part 14U of the pile 14.

  Next, although the example which formed the support | pillar 20 by the upper part 14U and the pillar 18 of the pile 14 was shown in the said 1st Embodiment, you may form the support | pillar 20 only by the pile 14. FIG. That is, at least a part of the column 20 may be formed by the pile 14.

[Second Embodiment]
Next, a construction method for a structure according to the second embodiment will be described. In addition, about the construction method similar to 1st Embodiment, description is abbreviate | omitted suitably.

  In the said 1st Embodiment, although the example which constructs the structure 10 in which the foundation structure was made into a pile foundation was shown, in 2nd Embodiment, as shown in FIG. The constructed structure 70 is constructed. Hereinafter, each construction process of the structure 70 is demonstrated concretely.

  First, a support | pillar construction process is demonstrated. In the strut construction step, a plurality of struts 72 of the ground 12 are constructed as shown in FIG. The column 72 is erected on, for example, a discarding cup or a footing (not shown).

  In the present embodiment, the upper portion of the support column 72 is a main column on the first floor F1 of a structure 80 (see FIG. 11B), which will be described later, but a temporary column is built in the column building process. In the post-construction, a permanent pillar on the first floor F1 may be constructed.

  Next, the structure construction process will be described. In the structure constructing step, as shown in FIG. 10B, a beam 74 is constructed between column heads of adjacent columns 72 to construct a frame 76 and a floor (not shown) is constructed on the beam 74.

  Subsequently, as shown in FIG. 11A, the second floor F2 of the structure 80 is constructed on the support 72 in the structure construction step. At this time, the embankment process is performed in parallel with the construction of the second floor F2. That is, the embankment is raised while compacting the earth and sand on the ground 12 under the structure 80, and the substantially trapezoidal embankment 50 is constructed in an elevational view.

  Subsequently, as shown in FIG. 11B, in the structure construction step, the upper floor FU of the structure 80 is constructed. At this time, the foundation construction process is performed in parallel with the construction of the upper floor FU. That is, the foundation 78 is constructed on the upper surface 50U of the embankment 50. The foundation 78 is a direct foundation, and is formed of, for example, a reinforced concrete foundation slab. In addition, you may form the foundation 78 by a foundation beam etc. similarly to 1st Embodiment.

  Next, effects of the second embodiment will be described.

  In the present embodiment, a plurality of struts 72 are constructed on the ground 12 in the strut construction step. Next, in the structure construction process, a beam 74 as a part of the structure 80 is installed between the columns 72 and a floor (not shown) is constructed on the beam 74.

  Subsequently, as shown in FIG. 11A, the second floor F2 of the structure 80 is constructed on the support column 72 in the structure construction step. At this time, the embankment process is performed in parallel with the structure construction process. That is, the embankment 50 is constructed under the structure 80 in parallel with the construction of the upper floor FU of the structure 80.

  Thus, in this embodiment, the structure construction process and the embankment process can be performed in parallel by constructing the plurality of support columns 72 on the ground 12 prior to the embankment process. Therefore, the construction period can be shortened as in the first embodiment.

  In the present embodiment, the foundation 78 is directly used as the foundation. By simplifying the foundation 78 in this way, the construction period can be further shortened.

[Modification]
Next, a modification of the second embodiment will be described.

  In the said 2nd Embodiment, although the support | pillar 72 used as the pillar of the 1st floor F1 of the structure 80 was shown in the support | pillar construction process, it was not restricted to this. In the strut construction process, a strut 72 having a height T or more of the embankment 50 may be constructed.

  Specifically, as shown in FIG. 12A, in the strut construction step, a strut 72 having a height H substantially the same as the height T of the embankment 50 (see FIG. 12B) is constructed. Then, in the structure building process, a frame 92 is constructed by laying a beam 90 as a foundation beam between the columns 72.

  Subsequently, as shown in FIG. 12B, in the structure construction step, the first floor F1 of the structure 80 is constructed on the support column 72. In addition, the embankment process is performed in parallel with the construction of the first floor F1. That is, the embankment 50 having a predetermined height T is constructed by raising the earth and sand under the beam 90. Thereby, the support | pillar 72 is embed | buried in the embankment 50. FIG.

  Thus, in the support | pillar construction process, by constructing | assembling the support | pillar 72 more than the height T of the embankment 50 in the ground 12, a structure construction process and a embankment process can be performed in parallel. Therefore, the construction period can be shortened. Also in 1st Embodiment, a structure construction process and a banking process can be performed in parallel by building the support | pillar 20 more than the height T of the banking 50 in the ground 12. FIG.

  In addition, the support | pillar 72 is good also as a temporary member (member with the intensity | strength which can be constructed | assembled at least to the first floor F1) until the foundation 78 or the beam 90 is constructed | assembled, and is good also as a permanent member. Further, the strut 72 can be subjected to the above-described friction cut.

  Moreover, in the said 2nd Embodiment, although the example which constructed one structure 70 was shown, when constructing the several structure 70, as FIG. 13 shows, for example, every structure 70 is shown. The embankment 50 may be constructed, and finally the embankment 94 between these embankments 50 may be filled to construct one embankment 96. In the case of constructing a plurality of structures 10 also in the first embodiment, even if the embankment 50 is constructed for each structure 10, and finally a groove between these embankments 50 is filled, one embankment is constructed. good.

  The first and second embodiments of the present invention have been described above. However, the present invention is not limited to such first and second embodiments, and the first and second embodiments and various modified examples are appropriately used. Of course, they may be used in combination, and can be implemented in various modes within the scope of the present invention.
