Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipe culverts, in particular to an in vitro reinforcing component of a corrugated pipe culvert. Background Art

[0002] Steel corrugated culverts, also called corrugated pipe culverts, refer to threaded corrugated pipes used for culverts buried under roads and railways. They are circular steel structure pipes made of corrugated steel sheets or assembled with corrugated steel sheets. The corrugated structure of the metal corrugated pipe culvert can make the culvert pavement bear force reasonably, the load distribution is uniform, and it has a certain anti-deformation ability. It can solve the problem of damage to the concrete structure of bridges and pipe culverts in the cold northern regions (frost); make the road surface free of expansion joints, improve driving comfort; help improve the "misalignment" phenomenon at the junction of the soft soil foundation structure and the embankment, and improve driving safety;

[0003] For example, the public document: CN208594495U, named "A reinforced steel corrugated pipe culvert", includes an outer corrugated plate and an inner corrugated plate arranged parallel to the outer corrugated plate, the outer corrugated plate and the inner corrugated plate are fixed by high-strength bolts, the trough of the outer corrugated plate and the trough of the inner corrugated pipe form a cavity, and a reinforcing steel belt arranged at 90° with the trough of the outer corrugated plate is arranged in the cavity. The utility model is applicable to steel corrugated pipe culverts.

[0004] The above-mentioned existing corrugated culvert has multiple components added to its outside to improve the strength of the corrugated culvert, but the corrugated culvert reinforcement components all protrude from the outside of the corrugated culvert, which not only easily affects the normal assembly of the corrugated culvert, but also increases the probability of collision of the reinforcement components, thereby affecting the service life of the reinforcement components and increasing cost expenditure; therefore, it does not meet the existing needs. In this regard, we propose an in vitro reinforcement component for the corrugated culvert. Utility Model Content

[0005] The utility model aims to provide a corrugated culvert outer reinforcement component which does not protrude from the outer wall of the corrugated culvert and improves the pressure-bearing strength, so as to solve the problems raised in the above-mentioned background technology.

The reinforcing rib is a circular ring structure, and its volume is larger than the second corrugated steel sheet and smaller than the first corrugated steel sheet;

[0009] The reinforcing steel component is installed on the outer wall of the reinforcing rib and is distributed in an annular manner at intervals. The reinforcing steel component is composed of two symmetrically arranged assembly blocks on the left and right.

[0010] Preferably, a raised end is provided at the middle position of the outer wall of the bottom of the assembly block, and the raised end is installed between two reinforcing ribs, and recessed ends are provided on both sides of the raised end, and the recessed ends are installed on the reinforcing ribs.

[0011] Preferably, a first assembly hole is formed on the outer wall of the assembly block, and a plurality of second assembly holes are formed on the outer wall of the reinforcing rib and are distributed in an annular pattern at intervals, and the second assembly holes have the same size as the first assembly holes.

[0012] Preferably, a connecting hole is provided at the middle position of the assembly block, a reinforcing rib is provided inside the connecting hole, and the reinforcing rib passes through the connecting hole and extends to another assembly block.

[0013] Preferably, a plurality of connecting channels for reinforcing ribs to pass through are provided on the side walls of the first corrugated steel structural piece.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model improves the pressure-bearing strength of the corrugated culvert by setting up reinforcing ribs and reinforcing steel components, and compared with the external components of the existing corrugated culvert, after the external components are installed and formed, they are embedded in the groove formed by the first corrugated steel sheet and the second corrugated steel sheet, and will not protrude from the outside of the first corrugated steel sheet, so that they are less likely to be damaged than other components protruding from the outside, thereby improving their service life; by installing two left and right reinforcing ribs in each groove, the pressure-bearing strength of the corrugated culvert is improved, and by setting up the reinforcing steel components, the reinforcing ribs are fixed and restricted on the second corrugated steel sheet, thereby improving stability and firmness.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-5The utility model provides an embodiment: an in vitro reinforcement member of a corrugated pipe culvert, comprising: a corrugated pipe culvert body 1, the corrugated pipe culvert body 1 is composed of a plurality of first corrugated steel sheets 2 and a plurality of second corrugated steel sheets 3, and the size of the first corrugated steel sheets 2 is larger than the second corrugated steel sheets 3, and the second corrugated steel sheets 3 are located between two first corrugated steel sheets 2;

[0027] Also includes:

[0028] The reinforcing ribs 4 are installed in the grooves formed between the second corrugated steel sheet 3 and the first corrugated steel sheet 2. Two symmetrically arranged reinforcing ribs 4 are arranged in each groove. The reinforcing ribs 4 are annular structures, and their volume is larger than the second corrugated steel sheet 3 and smaller than the first corrugated steel sheet 2.

[0029] The reinforcement steel member 5 is installed on the outer wall of the reinforcement rib 4 and is distributed in an annular manner. The reinforcement steel member 5 is composed of two symmetrically arranged assembly blocks 6 on the left and right.

[0030] By setting the reinforcing ribs 4 and the reinforcing steel components 5, the external reinforcement components can improve the pressure-bearing strength of the corrugated culvert. Compared with the external components of the existing corrugated culvert, after the external components are installed and formed, they are embedded in the groove formed by the first corrugated steel sheet 2 and the second corrugated steel sheet 3, and will not protrude from the outside of the first corrugated steel sheet 2, so that they are less likely to be damaged than other components protruding from the outside, thereby improving their service life. By installing two left and right reinforcing ribs 4 in each groove, the pressure-bearing strength of the corrugated culvert is improved, and by setting the reinforcing steel components 5, the reinforcing ribs 4 are fixed and restricted on the second corrugated steel sheet 3, thereby improving stability and firmness.

[0031] See also Figure 4 , a raised end 7 is provided at the middle position of the outer wall at the bottom of the assembly block 6, and the raised end 7 is installed between the two reinforcing ribs 4, and recessed ends 8 are provided on both sides of the raised end 7, and the recessed ends 8 are installed on the reinforcing ribs 4;

[0032] Since each group of two reinforcing ribs 4 is installed in the groove, a structure with protrusions on both sides and a recessed structure in the middle is formed inside the groove; the protruding end 7 is located in the middle of the assembly block 6. After the assembly block 6 is installed on the reinforcing rib 4, the protruding end 7 just rests against the recessed structure in the middle of the groove, while the recessed ends 8 on both sides fit the reinforcing rib 4, so that the assembly block 6 can effectively adapt to the structure in the groove and improve the assembly fit.

[0037] Furthermore, the reinforcing ribs 4 and the reinforcing steel members 5 are made of stainless steel;

In outdoor environments, it can resist most chemical media, including acids, alkalis, salts, etc., and is suitable for corrugated culverts such as those installed in areas with harsh environments. In addition, stainless steel has a mature manufacturing process and a relatively low cost.

[0039] Working principle: When in use, the reinforcing ribs 4 are installed on the second corrugated steel sheet 3 in groups of two, and the corrugated culvert is arranged and combined in the manner of the first corrugated steel sheet 2 and the second corrugated steel sheet 3. The assembly block 6 is installed on the reinforcing rib 4, and its raised end 7 is pressed against the recessed structure in the middle of the groove, and the recessed ends 8 on both sides are pressed against the reinforcing rib 4;

[0040] Align the first assembly hole 9 with the second assembly hole 13, and then reinforce with bolts, so that the bolts pass through the reinforcing rib 4 from the first assembly hole 9 and extend to the assembly hole of the second corrugated steel structure 3, and fix the assembly block 6 and the reinforcing rib 4 on the second corrugated steel structure 3;

[0041] A reinforcing rib 11 is passed through the notch at the end of one end, a plurality of assembly blocks 6 are penetrated and combined at the same position, and a plurality of first corrugated steel sheets 2 are penetrated.
