Abstract
The utility model discloses a structure suitable for pipe culvert reinforcement, which adopts a chemical anchor bolt to install a fixed cushion block in the original pipe culvert, installs the processed and assembled steel corrugated pipe on the fixed cushion block, connects the steel corrugated pipe segments through flange bolts, and the segments are staggered inside and outside according to the incoming water direction; corrugated steel pipe and fixed cushion block pass through flange bolted connection fixed, and the gap between corrugated pipe end and the culvert is clogged closely knit, pours self-compaction concrete into the hole of reserving through corrugated steel pipe, packs closely knit with the space between corrugated steel pipe and the former pipe culvert. The utility model provides a structure can be consolidated the pipe culvert that disease influence structure bearing capacity and durability has appeared, resumes culvert bearing capacity and durability, guarantees structural safety, does not influence the requirement of usability such as culvert water simultaneously.
Description
Technical Field
The utility model belongs to the technical field of bridge engineering, in particular to be applicable to reinforced structure of pipe culvert.
Background
The pipe culvert structure of the existing highway in China has complete set of design technical specifications and construction technical specifications. Because the early-stage pipe culvert material is mostly made of masonry materials or concrete materials, after a certain period of time, cracks appear on the surfaces of the masonry structures and the concrete structures, accumulated water seeps along the cracks and washes the culvert foundation, so that the pipe culvert sinks wholly or partially, and particularly in northern areas of China, the cracks are more serious due to the freeze-thaw action, the seepage of water is more obvious, and the structure safety and the driving safety of passing vehicles are seriously influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art not enough, provide a be applicable to reinforced (rfd) structure of pipe culvert, through at pipe culvert internally mounted corrugated steel pipe and pour into self-compaction concrete, solved the structure fracture, cross the problem that the bearing capacity that water infiltration leads to is not enough.
The technical scheme is as follows:
a structure suitable for reinforcing a pipe culvert is characterized in that a chemical anchor bolt is adopted in an original pipe culvert to install a fixed cushion block, a processed and assembled steel corrugated pipe is installed on the fixed cushion block, sections of the steel corrugated pipe are connected through flange bolts, and the sections are staggered from one another according to the incoming water direction; corrugated steel pipe and fixed cushion block pass through flange bolted connection fixed, and the gap between corrugated pipe end and the culvert is clogged closely knit, pours self-compaction concrete into the hole of reserving through corrugated steel pipe, packs closely knit with the space between corrugated steel pipe and the former pipe culvert.
Furthermore, the connection width between the steel corrugated pipe sections is 10-20 cm, and the height of the fixed cushion block is 10-15 cm.
The self-compacting concrete has better fluidity, and ensures that the steel corrugated pipe and the original pipe culvert are compact and have no gap after being poured. Inside the steel bellows reinforcement structure of adopting of existing pipe culvert that has the disease, can let the water smoothly pass through the culvert, prevent simultaneously that the structure from producing the crack and leading to crossing the infiltration to arouse that the basis is washed the structure bearing capacity that causes and go wrong, guarantee structure and past vehicle safety of traveling.
Drawings
Figure 1 is a schematic view of a pipe culvert reinforcement construction.
Description of reference numerals: the pipe culvert comprises an original pipe culvert 1, a fixed cushion block 2, flange bolts 3, a steel corrugated pipe 4 and self-compacting concrete 5.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description is provided for the construction suitable for pipe culvert reinforcement provided by the present invention with reference to the embodiments. The following examples are intended to illustrate the invention and are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, the utility model discloses a pipe culvert reinforcing structure, include: laying a fixed cushion block 2 in the original pipe culvert 1, connecting a steel corrugated pipe 4 which is processed and spliced by a flange bolt 3 with the fixed cushion block 2, connecting the steel corrugated pipe segments by the flange bolt 3, and then pouring self-compacting concrete 5.
Corrugated steel pipe installs on fixed cushion, and corrugated steel pipe passes through flange bolted connection with fixed cushion, and fixed cushion and former pipe culvert pass through chemical bolted connection, and fixed cushion height should be 10 ~ 15cm, and convenient self-compaction concrete fills closely knit, and is less to crossing the water section influence.
During construction, firstly, mounting a chemical anchor bolt on an original pipe culvert; secondly, connecting the fixed cushion block with the original pipe culvert through a bolt; thirdly, mounting the spliced corrugated steel pipe on a fixed cushion block, and connecting and fixing the corrugated steel pipe and the fixed cushion block by using flange bolts; and fourthly, filling the gap between the end of the corrugated pipe and the pipe culvert to be compact, pouring self-compacting concrete into the hole reserved by the steel corrugated pipe, and filling the gap between the steel corrugated pipe and the original pipe culvert to be compact.
Engineering practices show that after the pipe culvert with water seepage diseases is reinforced by the structure, water does not seep and scour the foundation, and the problem that the bearing capacity and durability of the structure are affected is solved.
The utility model discloses can consolidate the pipe culvert that disease influence structure bearing capacity and durability has appeared, resume culvert bearing capacity and durability, guarantee structure safety, do not influence the requirement of usability such as culvert water simultaneously.
The present invention is not limited to the above-described examples, and various changes that can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art can be considered as the protection scope of the present invention.
Claims (2)
1. A structure suitable for pipe culvert reinforcement is characterized in that a chemical anchor bolt is adopted in an original pipe culvert to install a fixing cushion block, a processed and assembled steel corrugated pipe is installed on the fixing cushion block, sections of the steel corrugated pipe are connected through flange bolts, and the sections are staggered from one another according to the incoming water direction; corrugated steel pipe and fixed cushion block pass through flange bolted connection fixed, and the gap between corrugated pipe end and the culvert is clogged closely knit, pours self-compaction concrete into the hole of reserving through corrugated steel pipe, packs closely knit with the space between corrugated steel pipe and the former pipe culvert.
2. The structure suitable for pipe culvert reinforcement according to claim 1, wherein the connection width between the steel corrugated pipe segments is 10-20 cm, and the height of the fixing cushion block is 10-15 cm.
