Embodiment 1

[0069] see figure 1 , the present embodiment provides a prefabricated channel construction method, comprising steps:

[0070] S1: Excavation of 500 foundation pits.

[0071] Specifically, during construction, excavation is carried out at the culvert first, so as to form the foundation pit 500 .

[0072] S2: Lay the cushion layer 100 at the bottom of the foundation pit 500 .

[0073] Specifically, the cushion layer 100 is formed by pouring cement soil or concrete at the bottom of the foundation pit 500, and it is necessary to ensure that the elevation and flatness of the cushion layer 100 meet the requirements of the design drawings, for example, the surface flatness of the cushion layer 100 needs to be within 2 cm.

[0074] S3: Install the base plate 200 on the cushion layer 100 .

[0075] Specifically, the bottom plate 200 is hoisted onto the cushion layer 100, and the bottom plate 200 is adjusted to be horizontal.

[0076] S4: Install side plates 300 on both sides of the...

Embodiment 2

[0141] In this embodiment, on the basis of the first embodiment, a transportation method for the bottom plate 200 , the side plate 300 and the top plate 400 is proposed. In the above embodiment, optionally, the prefabricated channel construction method further includes step S0 before step S1:

[0142] S001: When the bottom plate 200, the side plate 300 and the top plate 400 are all curved corrugated plates, place the largest corrugated plate on the carriage, and set the arched side of the corrugated plate upwards, and place it at the bottom of the largest corrugated plate Lay multiple sleepers whose height matches the corrugated board and lay straps;

[0143] S002: Stack corrugated boards with decreasing volume or weight successively on the largest corrugated board, and place a round log assembly in the center between adjacent corrugated boards, the round log assembly includes at least three round logs, and at least three round logs Arranged at intervals along the direction p...

Embodiment 3

[0146] Such as Figure 5 to Figure 10 As shown, the present invention also discloses a prefabricated channel, including: a cushion layer 100 , a bottom plate 200 , at least two side plates 300 and a top plate 400 . The bottom plate 200 is set on the cushion layer 100. Between the bottom plate 200 and the cushion layer 100, a wedge-shaped block 120 and a positioning tie bar 110 are arranged. The wedge-shaped block 120 and the positioning tie bars 110 are located on both sides of the bottom plate 200 to level and fix the bottom plate. 200. Bottoms of at least two side panels 300 are respectively connected to two opposite sides of the bottom panel 200 . Two opposite sides of the top board 400 are respectively connected to the tops of the two side boards 300 . The bottom board 200 , the side boards 300 and the top board 400 jointly surround and form an annular channel 410 .

[0147] The prefabricated passage adopts any one of the above-mentioned prefabricated passage constructi...

Abstract

The invention discloses a fabricated channel construction method and a fabricated channel, and belongs to the field of underground channel construction. The fabricated channel construction method comprises the steps that S1, a foundation pit is excavated; S2, a cushion layer is laid at the bottom of the foundation pit; S3, a bottom plate is installed on the cushion layer; S4, side plates are correspondingly installed on the two sides of the bottom plate; S5, a top plate is installed at the tops of the two side plates, so that the bottom plate, the side plates and the top plate jointly form an annular channel; and S6, the outer side of the annular channel is filled with soil. The annular channel is easy to splice and install, steps are reduced, the construction period is shortened, the annular channel does not need to use a large amount of concrete and steel bars, and manufacturing cost is reduced. The bottom plate, the side plates and the top plate can select proper sizes according to the size of a culvert, customization is not needed, and the manufacturing cost is further reduced.

Description

technical field [0001] The present application relates to the field of underground passage construction, in particular to a construction method for a prefabricated passage and the prefabricated passage. Background technique [0002] Existing urban underground comprehensive pipelines and highway culverts are mostly made of reinforced concrete, and their structural forms include on-site integral pouring and prefabricated assembly. The traditional on-site overall pouring reinforced concrete construction steps include: foundation pit excavation, cushion concrete pouring, steel bar binding, foundation concrete pouring, wall cover plate steel bar binding concrete pouring, formwork removal, settlement joint treatment, backfilling of the abutment, etc. The whole project needs to use a large amount of cement and steel bars, the cost is high, and there are many construction steps, resulting in a long construction period. At the same time, due to the different sizes of the culverts, t...
