Fig. 3 is the below enlarged drawing of tectosome 1, and expression is arranged on the steel pipe sheet pile 3 of water-bed bottom 9.As stated, steel pipe sheet pile 3 is arranged at water-bed 5.Therefore, the below of steel pipe sheet pile 3 (water-bed bottom 9) is embedded in water-bed 5.At the joint that is arranged in water-bed bottom 9 13, a plurality of holes 21 are set on the base portion 17b of L type parts 15b with separating predetermined distance.That is, hole 21 is set in place at least on the base portion 17b of the L of water-bed bottom 9 type parts 15b.
Then, the joint 13 to 21 positions, hole illustrates in greater detail.Fig. 4 A, Fig. 4 B are the sectional views that comprises the hole 21 of joint 13.Fig. 4 A is the figure of expression steel pipe sheet pile 3a, the 3b state that is set at straight position (promptly, L type parts 15a, 15b each other the state of setting) non-contiguously.Fig. 4 B be expression steel pipe sheet pile 3a, 3b each other with the direction of closure approximate vertical on the figure of the state that is provided with of skew ground (promptly, the end of L type parts 15a and L type parts 15b are provided with contiguously state).
As stated, fill the concrete 23 that contains aggregate 25 to the inside of joint 13.Aggregate 25 can use various rubbles etc.As aggregate 25, also can use artificial aggregates such as natural aggregates such as extra large sand and blast-furnace slag.At this, aggregate 25 for example is coarse aggregate (aggregate that uses the screen cloth of 5mm, is retained more than 85% according to weight), and the size of particle for example is preferably about 20mm.At this, the size of the particle of aggregate 25, the general maximum size of expression coarse aggregate.For example, according to the granulometry of the coarse aggregate of JIS A 1102, the size of the particle of aggregate 25 is 20mm, and expression utilizes the screen cloth of nominal dimension 20mm, and the weight percent of the particle through screen cloth is 90～100%.That is, the size of the particle of coarse aggregate comprises the particle about general 5～20mm.
In addition,, mix sometimes and contain coarse aggregate and fines, but the size of the particle of the aggregate 25 among the present invention according to concrete difference, be meant the aggregate that mainly contains in the concrete, by the size of the particle of above-mentioned JIS regulation.For example, containing under the situation that fineness modulus or solid cubic content rate are the coarse aggregate A more than 50%, even contain other finess and particulate, also be meant this coarse aggregate A particle by the represented size of JIS.
In Fig. 4 A, Fig. 4 B, only illustrate the part of aggregate 25.In addition, the state before expression concrete 23 solidifies in Fig. 4 A, Fig. 4 B, aggregate 25 can freely move in joint 13 inside.
At this; Shown in Fig. 4 A; At steel pipe sheet pile 3a, 3b each other as the crow flies under the situation of opposite disposed, the gap between the base portion 17b external surface of the arm 19a front end of L type parts 15a and L type parts 15b is defined as B, the length till from the base portion 17b external surface of L type parts 15b to arm 19b front end is defined as C; Distance definition till from the arm 19b front end of L type parts 15b to the base portion 17a inner surface of L type parts 15a is D, and the diameter in hole 21 is defined as E.
Equally, shown in Fig. 4 B, having produced under the situation of peak excursion on the direction (arrow I direction among the figure) with respect to the closure approximate vertical at steel pipe sheet pile 3a, 3b, will be B ', D ' with the corresponding distance definition of B, D of Fig. 4 A.And the size definition of the particle of the aggregate 25 that concrete 23 is contained is d.
At this moment, can not break away from, under the state of Fig. 4 B that has squinted in steel pipe sheet pile position each other, need make C bigger the biglyyest than B ' from L type parts 15a in order to make L type parts 15b.
In addition, in joint 13, move (promptly, fill) easily for concrete 23 is got in order to make aggregate 25, the mobile route that need make aggregate 25 with respect to the size of aggregate 25 for enough greatly.It is former because when mobile route be hour with respect to aggregate 25, the path can be by aggregate 25 sealings, the filling of obstruction concrete 23.
At this, as the mobile route of aggregate 25, the gap (arrow G direction the figure) till for example existing from the arm 19b front end of L type parts 15b to the base portion 17a inner surface of L type parts 15a.Under the state of Fig. 4 B that has squinted in steel pipe sheet pile position each other, it is minimum that this gap becomes the biglyyest, and aggregate 25 can move and get final product under this state.That is, D ' enough gets final product greatly than d, if for example D ' is more than 2 times of d, then aggregate 25 can not stop up in this position, and can not hinder flowing of concrete 23, is preferred therefore.
In addition, as the mobile route of aggregate 25, in addition also there is hole 21 (arrow F direction among the figure).Therefore, E enough gets final product greatly than d, if for example E is more than 2 times of d, then aggregate 25 can not stop up in this position, and can not hinder flowing of concrete 23, is preferred therefore.
At this, as stated, the gap maximum between the base portion 17b external surface of the arm 19a front end of L type parts 15a and L type parts 15b becomes B '.When this gap was big with respect to the big or small d of aggregate 25, aggregate 25 (concrete 23) can flow out to the outside from this gap.For example,, there is water, so concrete 23 flows out in water in the outside in this gap on water-bed top 11 (Figure 1A).Therefore, water becomes dirty.Therefore, need prevent that concrete 23 is from this clearance leakage.
At this, if the size d of aggregate 25 greater than B ', then aggregate 25 stops up these gaps (arrow H direction among the figure).Therefore, through aggregate 25 these gaps of sealing, suppress the outflow of concrete 23.That is, preferred B ' is less than d.In other words, preferred B is less than general 1/2 of d.
Then, do not become certain to the distance between steel pipe sheet pile 3a, the 3b and situation that squinted describes.Fig. 5 A, Fig. 5 B are the sectional views of 21 positions, hole of joint 13.Fig. 5 A is that expression steel pipe sheet pile 3b is arranged on the figure near the locational state of steel pipe sheet pile 3a side, Fig. 5 B be expression steel pipe sheet pile 3b be arranged on steel pipe sheet pile 3a round about away from the figure of locational state.
Shown in Fig. 5 A, when steel pipe sheet pile 3a, 3b squinted to approaching each other direction (arrow J direction among the figure), the front end of L type parts 15b contacted (perhaps the front end of L type parts 15a contacts with steel pipe sheet pile 3b) with steel pipe sheet pile 3a, each other can be further not approaching.In this case, when fill concrete 23 in the scope of being surrounded by base portion 17b and steel pipe sheet pile 3a, 3b, concrete 23 is filled into base portion 17b each other, and through hole 21 (arrow K direction among the figure).Therefore, also be filled concrete 23 between opposed L type parts 15a and the L type parts 15b.
At this moment, as stated, aggregate 25 is blocked in the gap between the base portion 17b external surface of front end and L type parts 15b of L type parts 15a (arm 19a).Therefore, suppressing concrete 23 flows out from this gap.
Then, shown in Fig. 5 B, steel pipe sheet pile 3a, 3b are described to the situation of the direction of leaving each other (arrow N direction among the figure) skew.In this case, as stated, arm 19b can not break away from from arm 19a, so keep steel pipe sheet pile 3a, 3b connection each other yet.
Because between the side of arm 19b and steel pipe sheet pile 3a, form bigger gap, so concrete 23 is filled in the space by L type parts 15a, 15b and steel pipe sheet pile 3a, 3b flanked reliably, aggregate 23 can not stop up.
On the other hand, base portion 17b exposes in the outside of arm 19a.Therefore, the outside of joint 13 is communicated with through hole 21 with inner.Therefore, the concrete 23 that contains aggregate 23 might pass through hole 21 to outside outflow (arrow M direction among the figure).
But,, therefore have sand in the outside of joint 13 because hole 21 only is arranged on water-bed bottom 9 (Figure 1A and Fig. 3).Therefore, suppress to have passed through the outflow of the concrete 23 in hole 21 by sand.In addition, even hypothesis flows out a little, owing to leaning on the bottom than water-bed 5 around the hole 21, so can directly not make water become dirt.Therefore, can be owing to the cast of concrete 23 contaminant water.
Then, the formation to the joint 13 on water-bed top 11 (Figure 1A) describes.As stated, on water-bed top 11, there is water in joint 13 outsides.Therefore, when concrete 23 grades when joint 13 flows out, water becomes dirty thus.Therefore, need prevent that concrete 23 is to joint 13 outside outflows.In this embodiment, as stated,, make the gap smaller between arm 19a front end and the base portion 17b, so, prevent that concrete 23 from flowing out from this gap through aggregate 25 landfill gaps with respect to the size of aggregate 25.But,, preferably on arm 19a, seal member is set in order to prevent the outflow of concrete 23 more reliably.
Fig. 6 A, Fig. 6 B, Fig. 6 C are illustrated in the figure that is provided with the state of seal member on the arm 19a.Shown in Fig. 6 A, on the external surface of arm 19a, the seal member 27a towards the preceding extreme direction extension of arm 19a is set.Seal member 27a be can elastic-plastic deformation material, for example can use the resin etc. of metal system and the rubber etc. of steel sheet etc.Seal member is arranged in the scope on water-bed top 11 (Figure 1A) from the top of steel pipe sheet pile 3 at least.It is former because in water-bed bottom 9 (Figure 1A), as stated, sand on every side plays the effect of seal member.
In addition, shown in Fig. 6 A, also seal member 27a can be set with prebending.In addition, shown in Fig. 6 B, also can seal member 27b be set as the crow flies with respect to arm 19a.The sort of mode no matter, seal member can both contact with the base portion 17b of the steel pipe sheet pile 3b side that engages object and be out of shape, and the gap between obstruction arm 19a and the base portion 17b.In following explanation, the example that has used seal member 27a is described.
Fig. 6 C is the figure of expression steel pipe sheet pile 3a, the connected state of 3b.Shown in Fig. 6 C, on the arm 19a of pair of L type parts 15a, the outstanding seal member 27a of direction ratio arm 19a to the inside is set each other.The front end of seal member 27a contacts with the base portion 17b external surface that conduct engages the steel pipe sheet pile 3b of object.Seal member 27a can elastic-plastic deformation, so also follow for the skew (skew that Fig. 4 B is such) of steel pipe sheet pile 3a, 3b, the gap between arm 19a and the base portion 17b is blocked.Therefore, even, also can prevent the concrete 23 (arrow O direction among the figure) that flows out a little reliably through the gap between aggregate 25 obstruction arm 19a and the base portion 17b.
Fig. 7 A representes to be provided with the L type parts 15a of the state of seal member 27a.Fig. 7 A is the front view of observing from the direction of engagement side of L type parts 15a, and Fig. 7 B is the P-P line sectional view of Fig. 7 A, and Fig. 7 C is the Q-Q line sectional view of Fig. 7 A.
Seal member 27a steel pipe sheet pile 3 axially on be provided with along L type parts 15a.Tapered portion 29 is set above seal member 27a.Tapered portion 29 forms, and it is big that the front end of a pair of seal member 27a interval each other becomes towards the top.That is, above seal member 27a, the tapered portion 29 that the width (cross-directional length) of formation seal member 27a diminishes towards the top gradually.
Shown in Fig. 7 B, near steel pipe sheet pile 3b upper end, the cross-directional length of seal member 27a is shorter.For example, be arranged on the seal member 27a on the external surface of arm 19a, outstanding near the upper end from the front end of arm 19a, and guarantee a pair of arm 19a interval each other.That is, in Fig. 7 B, illustrate the L type parts 15b that engages object with dotted line, but the base portion 17b of L type parts 15b does not contact and contacts with arm 19a with seal member 27a.Therefore, from above with L type parts 15b (steel pipe sheet pile 3b) when L type parts 15a (steel pipe sheet pile 3a) embeds, seal member 27a does not contact with L type parts 15b.Therefore, can the insertion property of L type parts 15b not exerted an influence, operability is good.
On the other hand, shown in Fig. 7 C, the below of the tapered portion 29 of seal member 27a (being positioned at the position of water surface below) is that seal member 27a gives prominence to the length amount that is enough to stop up the gap from arm 19a front end, and contacts with base portion 17b.Therefore, stop up the gap between arm 19a and the base portion 17b through seal member 27a.Therefore, concrete can not flow out from this gap.
In addition, in above embodiment, only hole 21 is set, and only seal member 27a is set, but be not limited thereto on water-bed top 11 in water-bed bottom 9.For example, also can seal member 27a be set to water-bed bottom 9 till, in addition also can be in 11 formation holes 21, water-bed top.Even in 11 formation holes 21, water-bed top, make up less than the size of aggregate 25 or with seal member 27a through the size that makes hole 21, also can prevent concrete leakage thus.
According to the joint method of the steel pipe sheet pile of this embodiment, can engage steel pipe sheet pile simply each other, and concrete fillibility is good, and can prevents reliably that concrete from flowing out in water.In addition, because the sectional area that is surrounded by L type parts 15a, 15b is bigger, therefore can access higher shearing resistance at the junction surface.
Especially, owing to carry out steel pipe sheet pile 3a, 3b joint each other through the joint 13 that has used L type parts 15a, 15b, therefore for example pair of L type parts 15b is inserted between the pair of L type parts 15a and gets final product, bonding operation property is good.In addition, in the concrete 23 as packing material, contain aggregate 25, the gap between the base portion 17b external surface of the arm 19a front end of L type parts 15a and L type parts 15b is less than the size of aggregate 25.Therefore, aggregate 25 is blocked in this gap, can suppress concrete 23 and further flow out.
In addition, the gap between the base portion 17a inner surface of the arm 19b front end of L type parts 15b and L type parts 15a is enough big with respect to the size of aggregate 25.Therefore, concrete 23 can be filled in the space between L type parts 15a, the 15b reliably.
In addition, if at least in water-bed bottom 9, on base portion 17b, form hole 21, then in the concrete 23 entering holes 21, can improve the adhesive strength between concrete 23 and the L type parts 15b.Therefore, can access higher shearing resistance at the junction surface.In addition, because the size in hole 21 be enough greatly with respect to the size of aggregate 25, so when the space fluid concrete 23 between L type parts 15a, 15b, concrete 23 passes through hole 21.Therefore, can more reliably concrete 23 be filled in the space.
In addition, be provided with under the situation of seal member 27a, can suppress concrete 23 more reliably and flow out from the gap between arm 19a front end and the base portion 17b external surface on water-bed top 11.Therefore, can prevent that concrete 23 from flowing out in water and the water that causes becomes dirty.
In addition, have on the top of seal member 27a under the situation of tapered portion 29, when inserting L type parts 15b to L type parts 15a, seal member 27a can not hinder insertion.Therefore, can insert L type parts 15b along tapered portion 29.
In addition, on the inner surface (with the contact surface of concrete 23) of L type parts 15a, 15b, be pre-formed under the concavo-convex situation, the adhesive strength between concrete 23 and L type parts 15a, the 15b improves.Therefore, the shearing resistance at junction surface improves.
