[0040] The principles and features of the present invention will be further described hereinafter with reference to the accompanying drawings, and the embodiments listed herein are only intended to explain the present invention, rather than limiting the scope of the present invention.
[0041] Embodiment 1:
[0042] As shown in FIG. 1, the present embodiment provides a culvert section, including a top cover 11 and two side walls 12. The two side walls 12 are vertically arranged in a front-back direction and distributed at intervals in a left-right direction. The top cover 11 is horizontally arranged in the front-back direction, and a left side and a right side of the top cover are supported at upper ends of the two side walls 12 respectively. An upper end of each of the side walls 12 is connected to a corresponding side of the top cover 11. In this way, each culvert section is assembled from the top cover and the two side walls, such that the whole culvert section can be transported more conveniently {that is, each culvert section may be divided into the top cover and the two side walls for transport).
[0043] At this time, the top cover and the two side walls are combined into an n-shaped structure. The lower ends on the two sides of the top cover and the upper ends of the two side walls may be bonded by cement slurry {the upper ends of the side walls are connected to the lower ends on the corresponding sides of the top cover after 09858 solidification of the cement slurry).
[0044] Preferably, in the technical solution described above, the side wall 12 includes a bottom bracket 121 and a vertical wall 122. The bottom bracket 121 is a strip plate horizontally arranged in the front-back direction. The vertical wall 122 is vertically arranged on the bottom bracket 121 in the front-back direction. A front end and a rear end of the vertical wall 122 are flush with a front end and a rear end of the bottom bracket 121 respectively. An upper end of the vertical wall 122 constitutes the upper end of the side wall 12. The bottom bracket is arranged at the lower end of the vertical wall, such that the stability of the side wall in a foundation pit is improved, and collapse of the side wall caused by uneven stress at the upper end of the culvert section is thus avoided. Further preferably, a left side and a right side of the bottom bracket 121 protrude from a left side and a right side of the corresponding vertical wall 122 (i.e, the cross section of the side wall is inverted T-shaped), which further improves the stability of the side wall in the foundation pit. In addition, the bottom bracket may further increase the area of contact between the lower end of the side wall and the botiom of the foundation pit, thus reducing the pressure of the side wall on the bottom of the foundation pit and avoiding or reducing the risk of downward settlement of the side wall in the later period.
[0045] in the technical solution described above, the length of the top cover 11 and the length of the side wall 12 are the same, and thus, after the top cover and the two side walls are assembled, their front and rear ends are aligned.
[0046] In the technical solution described above, the side wall 12 and the top cover 11 are both reinforced concrete prefabricated members (in which the bottom bracket and the vertical wall are integrally cast with reinforced concrete), which are high in strength and iow in cost.
[0047] The top cover may be slab-shaped, or has an n-shaped cross section (te, the top cover has downward bends on both sides).
[0048] Embodiment 2:
[0049] As shown in FIG. 2, on the basis of Embodiment 1, in this embodiment, in order to improve the stability of connection between the top cover and the upper ends of the two side walls, the upper end of the vertical wall 122 is dented downwards to form an assembly groove 1221, lower ends on two sides of the top cover 11 protrude downwards to form bosses 111 that match the assembly groove 1221, and the bosses
111 on the two sides of the top cover 11 respectively extend into the assembly grooves 1221 at the upper ends of the vertical walls 122 on the corresponding sides. In this Way, 999952 the top cover may be embedded into the upper ends of the corresponding two side walls, such that the top cover may be limited in the left-right direction to avoid displacement in the left-right direction.
[0050] The assembly groove 1221 may be a U-shaped groove, which is formed by recessing the middie of the vertical wall and runs through the front end and the rear end of the vertical wall. At this point, the boss is a strip-shaped protrusion arranged in the front to rear direction and may exactly exiend into the assembly groove. At this point, during assembly of the side wall and the top cover, a groove wall of the assembly groove and an edge of the boss may be roughened in advance, then the assembly groove is uniformly filled with cement slurry, and the top cover is assembled in place at the upper end of the side wall (the bonding effect of the cement slurry may be obviously improved by roughening treatment).
[0051] Embodiment 3:
[0052] As shown in FIGS. 3-12, this embodiment provides an assembly type culvert, including a plurality of culvert sections 1 as described in Embodiment 1 or Embodiment 2. The plurality of culvert sections 1 is sequentially arranged in a front-back direction.
Ends of every two adjacent culvert sections 1 close to each other are attached and aligned, and the ends of every two adjacent culvert sections 1 close to each other are connected by means of a connecting piece 2 (at this time, every two adjacent side walls on the same side are connected by means of a connecting piece, and every two adjacent top covers are also connected by means of a connecting piece), such that the culvert can be assembled from a plurality of culvert sections. Thus, the construction length of the assembly type culvert is not limited. in addition, every two adjacent culvert sections are connected by means of the connecting piece, such that the stability of the whole assembly type culvert is improved. Further, the culvert sections can be prefabricated, and then transported to a site for assembly construction. Therefore, the construction efficiency is high.
[0053] In the technical solution described above, first curved holes 1222 are formed in ends of every two adjacent vertical walls 122 close to each other on the same side. One end of the first curved hole 1222 is located at an end portion of the vertical wall 122, and the other end of the first curved hole 1222 is located on a side of the vertical wall 122 corresponding to an outside of the culvert section 1. The first curved holes 1222 at the ends of every two vertical walls 122 close to each other are aligned with each other and together form one arc-shaped hole. One of the connecting pieces 2 is inserted into the arc-shaped hole to connect the two adjacent vertical walls 122. In this way, the two 99952 adjacent vertical walls in the two adjacent culvert sections are connected to each other by means of the connecting piece, such that any two adjacent vertical walls can be prevented from moving forward and backward.
[0054] in the technical solution described above, a plurality of first curved holes 1222 are vertically formed at intervals in the ends of every two adjacent vertical walls 122 close to each other on the same side in one-lo-one correspondence. The corresponding two first curved holes 1222 are aligned with each other and together form one arc- shaped hole. One of the connecting pieces 2 is inserted into sach of the arc-shaped holes. In this way, the two adjacent side walls are in better connection.
[0055] The first curved hole 1222 needs to be reserved during prefabrication of the side wall, and a centering angle of the first curved hole needs to be less than 90°. For example, the two first curved holes are also aligned with each other to form one arc- shaped hole with a centering angle of less than 180° after the two adjacent side walls are aligned front and back.
[0056] in the technical solution described above, second curved holes 112 are formed in ends of every two adjacent top covers 11 close to each other. One end of the second curved hole 112 is located at an end portion of the top cover 11, and the other end of the second curved hole 112 is located at an upper end of the top cover 11. The second curved holes 112 at the ends of every two adjacent top covers 11 close to each other are aligned with each other and together form one arc-shaped hole. One of the connecting pieces 2 is inserted into the arc-shaped hole to connect the two adjacent top covers 11. In this way, no forward or backward displacement occurs between the two adjacent top covers.
[0057] in the technical solution described above, a plurality of second curved holes 112 are formed at intervals in a left-right direction in ends of every two adjacent top covers 11 close to each other in one-loc-one correspondence. The corresponding two second curved holes 112 are aligned with each other and together form one arc-shaped hole.
One of the connecting pieces 2 is inserted into each of the arc-shaped holes. In this way, the two adjacent top covers are in better connection.
[0058] À centering angle of the second curved hole is also less than 90°. When the two adjacent top covers are aligned with each other, the two second curved holes are aligned to form one arc-shaped hole with a centering angle of less than 180°.
[0059] As shown in FIG. 13, in the technical solution described above, the connecting piece 2 includes an arc-shaped sleeve 21, an arc-shaped screw 22 and at least two nuts 23. The arc-shaped sleeve 21 is inserted into the arc-shaped hole, and two ends of the arc-shaped slesve are located in the arc-shaped hole. The arc-shaped screw 22 passes through the arc-shaped sieeve 21, and two ends of the arc-shaped screw extend out of the arc-shaped hole. Each of the two ends of the arc-shaped screw 22 is in threaded connection with at least one of the nuts 23. Therefore, the installation is convenient, and the effect of connection is excellent.
[0060] The surfaces of the arc-shaped sleeve, the arc-shaped screw and the nut are all steel or iron members, and all need to be galvanized for preservative treatment, and of course they may also be aluminum alloy members.
[0061] Threads (their function is similar to that of a conventional arc-shaped bolt) are formed in both ends of the arc-shaped screw. Centering angles of both the arc-shaped screw and the arc-shaped sleeve are less than 180°.
[0062] Further preferably, the connecting piece further includes a gasket. The gaskets are arranged at both ends of the arc-shaped screw, and clamped on the top cover or the vertical wall by the nuts at the same end.
[0063] When each culvert section is assembled in place, there is still a gap at the side where the two bottom brackets are close to each other {concrete may be poured into the gap in the later period to form a concrete filling layer 3).
[0064] Embodiment 4:
[0065] As shown in FIGS. 14 and 15 this embodiment provides a method for constructing the assembly type culvert described in Embodiment 3. The method includes the following steps.
[0066] In step 1, directions of two side edges of the culvert are marked on the ground {may be marked with lime lines), and a foundation pit is excavated according to a designed depth of the foundation pit in the directions.
[0067] in step 2, an inner bottom of the foundation pit is compacted (until it is flat, and no obvious footprints may appear when adults step on it); the bottom of the foundation pit is filled with a crushed stone layer 5 with a depth of 0.5m to 1.5m {preferably 1m to 1.3m}; then a gravel layer 4 with a depth of 0.3m to 0.6m {preferably 0.4m to 0.5m} is filled at an upper end of the crushed stone layer 5; the gravel layer 4 is leveled and compacted, and a concrete layer 5 (C30 concrete) with a thicknass of 0.15m to 0.3m {preferably 0.2m) is poured at the upper end of the gravel layer 4. The concrete layer 6 needs to be leveled manually, and a vibrating pump may be used for tamping if
LU503852 necessary.
[0068] In step 3, settlement joints 7 are transversely arranged on the concrete layer 6 (Le. joints that cut off the concrete layer in a left-right direction are arranged, such that the concrete layer is divided into multiple sections in a front and back direction); and the settlement joints 7 are filled with bitumastic cakum. One settlement joint 7 is arranged every two culvert sections 1, and the settlement joints 7 need to be aligned with preset connection joints 8 of the two adjacent culvert sections 1;
[0069] in step 4, the side wall is hoisted and placed in place at the upper end of the concrete layer 6 according to a preset ling; a concrete filling layer 3 is filled between the bottom brackets on two sides; the upper end of the concrete filling layer 3 is leveled to be flush with the upper ends of the sides of the bottom brackets on two sides close to each other (preferably, at this time, steel bars are exposed on the sides of the two bottom brackets close to each other in the same culvert section, the exposed steel bars on the sides of the two bottom brackets close to each other in the same culvert section may be bound together, and then, concrete is poured to form a concrete filling layer, such that the concrete filling layer may connect the two bottom brackets of the same culvert section together and form them integrally, and it should be noted that a gap aligned with the connection joint is formed at an end portion of the concrete filling layer 3 in each culvert section, Le, the concrete filling layer in each culvert section is arranged independently, and the gap between every two adjacent concrete filling layers constitutes a part of the connection joint); the assembly groove at the upper end of the side wall is filled with cement slurry; the top cover is mounted in place; and then the two adjacent side walls and the two adiacent top covers are respectively connected by means of the connecting pieces. The gap between every two adjacent culvert sections constitutes the connection joint 8.
