Problems solved by technology

[0003] 1) The gullies cannot be constructed synchronously with the delamination of the subgrade and pavement structural layers;
[0004] 2) The construction period is long, and the construction of the next process can only be started after the block mortar or cast-in-place cement concrete reaches the working strength after 3 to 5 days;
[0005] 3) Backfill repair after back excavation, secondary labor and small machine tool operation, the quality is not easy to guarantee;
[0006] 4) Waste materials, excavate the newly paved roadbed and pavement structure, and generate muck and garbage

Embodiment 2

[0076] The prefabricated assembled gully in the second embodiment is a double grate gully, and the structures of the first shaft module 1, the second shaft module 2 and the first adjustment module 3 can be found in Figure 7a -c, its second adjustment module 4 see Figure 8a -c, its base module 5 see Figure 9a -c, the difference from Embodiment 1 is only the difference between the single grate and the double grate, which are consistent in principle, and will not be repeated here.

Embodiment 3

[0078] The prefabricated assembled gullies in the third embodiment are three-grain gullies, and the structures of the first shaft module 1, the second shaft module 2 and the first adjustment module 3 refer to Figure 10a -c, its second adjustment module 4 see Figure 11a -c, its base module 5 see Figure 12a -c, the difference from Embodiment 1 is only the difference between the single grate and the three grates, which are consistent in principle, and will not be repeated here.

[0079] The prefabricated assembled gullies in the above embodiments can start the construction of the next process without waiting for the block mortar or cast-in-place cement concrete to reach the working strength after 3 to 5 days, thereby shortening the construction time, especially suitable for urban road speed pass requirements; and, since there is no need to backfill and repair after multiple back excavations, material waste can be avoided; secondly, the modular gully body is easy to install an...

Abstract

The invention relates to the technical field of construction, and provides a prefabricated gutter inlet and a construction method thereof. A third well bore module of the prefabricated gutter inlet comprises a pedestal module and an adjusting module, and therefore the well bore can be modularized according to the road construction demand, the construction of the gutter inlet and the construction of the road structure can be carried out in a layered manner, the case that people need to wait until building block mortar or cast-in-site cement concrete reaches the construction intensity is avoided, and therefore the construction time is shortened, and the prefabricated gutter inlet especially meets the requirement that the town road needs to be opened quickly; in addition, each road structural layer is without repairing joints, a large machine is employed for the construction, and therefore the construction quality of the road is improved; finally, the case that the road needs to be excavated for many times, then is repaired through backfill is not needed, and thereof waste of materials can be avoided.

Description

technical field [0001] The invention relates to the technical field of urban road construction, in particular to a prefabricated and assembled gully. Background technique [0002] There are generally rainwater outlets on urban roads. For its general structure, please refer to figure 1 In construction, the subgrade or pavement base and cushion are generally back excavated, and masonry is used to build or install prefabricated modules or cast-in-place reinforced concrete. The specific method is: subgrade construction → reverse excavation of the foundation pit → masonry or installation or pouring the lower part of the rainwater outlet, placing rainwater branch pipes, backfilling and repairing → pavement cushion, base construction → back excavation of the foundation pit → masonry or installation or pouring rainwater The upper part of the mouth, backfilling and repairing. The disadvantages of this method are: [0003] 1) The gullies cannot be constructed synchronously with the...
