Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal underground pipeline construction, and specifically to a pipeline encapsulation and reinforcement structure. Background Art
[0002] On the one hand, with the development of cities, some old municipal pipelines cannot meet the production and living needs of the surrounding areas and need to be renovated and upgraded. During the renovation and upgrade process, there are areas where existing municipal roads, subways, rivers or other complex geological conditions need to be crossed. On the other hand, newly built municipal roads, subways, rivers, etc. in the city may also intersect with existing underground pipelines. In addition, there are also cases where pipelines are laid along newly built municipal roads. In such situations, whether actively or passively, when municipal pipelines cross areas such as roadbeds, subways, and rivers, encapsulation and reinforcement treatment are required.
[0003] For the encapsulation and reinforcement treatment of municipal pipelines, existing technical solutions mostly adopt the construction method of cast-in-place concrete, including setting out and surveying, excavating pipeline trenches, laying cushions; tying steel bars; installing formwork on both sides of the trench above the cushion and pouring the bottom concrete of the encapsulation structure; curing the bottom concrete; fixing the pipeline to the bottom of the encapsulation structure and pouring concrete to the top of the encapsulation structure; curing, removing the formwork, and the encapsulation is completed. The construction method of cast-in-place concrete has disadvantages such as cumbersome construction technology and long construction period.
[0004] Glossary of Terms:
[0005] Municipal underground pipelines: refer to various pipelines and their ancillary facilities buried underground within the city for purposes such as water supply, drainage, gas, heating, electricity, communication, radio and television, and industry. Municipal underground pipelines are an important part of urban infrastructure and are regarded as the "lifeline" of the city. They are responsible for transporting essential resources such as water, gas, electricity, and communication signals and are crucial for the normal operation of the city.
[0006] Encapsulation and reinforcement: A measure of using concrete to reinforce municipal pipelines within the depth of the roadbed of motor vehicle roads, within the scope of rivers, or in other areas with complex geological conditions. According to the specific stress conditions of the pipelines, there are generally two methods: plain concrete encapsulation and reinforced concrete encapsulation. Through encapsulation and reinforcement, effective sealing and protection of municipal pipelines can be achieved, avoiding structural damage to the pipelines under external forces such as vehicle loads and soil settlement. The safety and stability of the pipelines are improved, and the service life of the pipelines is extended. Content of the Utility Model

The concrete structure of the upper added solid 1 and the concrete structure of the lower added solid 2 are mirror images of each other.

Preferably, the connecting through-hole 5 is rectangular, and the length direction of the connecting through-hole 5 is parallel to the up-down direction.
[0054] The construction method of the described pipe encapsulation and reinforcement structure is introduced below.
[0055] Step 1: Calculate the dimensions of the mold for the encapsulated precast concrete block and the quantity of steel bar reinforcement according to conditions such as the size and stress conditions of the pipe 6, and perform mold making and steel bar binding.
[0056] Step 2: Prefabricate the upper added solid 1 and the lower added solid 2 of the precast components, and cure them.
[0057] Step 3: Set out and measure, excavate the pipe trench, detect the bearing capacity of the foundation at the bottom of the trench, and lay a cushion layer at the bottom of the pipe trench.
[0058] Step 4: Install the lower added solid 2, and the front lower insertion column 26 and the rear lower insertion hole 27 of two adjacent lower added solids 2 in the front and back are matched and inserted.
[0059] Step 5: Lay out the pipe 6, install the upper added solid 1, and the front upper insertion column 16 and the rear upper insertion hole 17 of two adjacent upper added solids 1 in the front and back are matched and inserted. The upper pipe installation groove 11 and the lower pipe installation groove 21 are connected to form a pipe installation through-hole 4, and the pipe 6 passes through the pipe installation through-hole 4 in a matching manner, as Figure 11 shown;

[0061] Step 7: Wait for the concrete in the connecting through holes 5 to solidify to form connecting blocks 3, backfill the soil in the trench, and the wrapping construction is completed.
[0062] The upper reinforcing member 1 and the lower reinforcing member 2 of the pipeline wrapping and strengthening structure are concrete precast members, which are used for modular assembly construction. Compared with the prior art construction method of tying steel bars on site and pouring concrete, the utility model is not affected by factors such as weather, saves the time cost generated by curing the cast-in-place concrete, and does not require tying steel bars on site. The construction quality is stable and the construction period is short.
[0063] The upper and lower "serrated" upper reinforcing member 1 and lower reinforcing member 2 can be initially fixed by pressing down heavily. Then tie the steel bars and pour concrete to achieve secondary fixation, making the structure more stable. Among them, this initial fixation can, on the one hand, ensure the straight connection of the wrapping structure in the longitudinal direction, and on the other hand, it also enables the next step of construction to be carried out without curing after the concrete in the recess has initially set.
[0064] The "inner circle and outer square" structure formed by the pipeline wrapping and strengthening structure can be closely attached to the pipeline internally and effectively isolate external forces externally, avoiding the deformation and damage of the pipeline due to the direct action of external forces on the pipeline.
[0065] The above is only a specific embodiment of the present utility model, and it cannot limit the scope of implementation of the utility model. Therefore, the replacement of equivalent components or the equivalent changes and modifications made according to the protection scope of the present utility model should still fall within the scope covered by the present utility model.
