Problems solved by technology

Since the back planing is carried out after it has been strengthened, the entire rainwater well masonry process takes a long period, the back planing is difficult and a lot of time and labor are wasted, and the construction efficiency is extremely low

Embodiment 1

[0038] refer to Figure 1 to Figure 5 , the present invention provides a kind of rainwater well lifting device under the road, the rainwater well comprises the first floor well chamber in the lime soil layer 5 below the road structure layer 4 and in the road structure layer 4 according to the height of each layer from the bottom Multi-layer well chambers built layer by layer or layer by layer, including:

[0039] A prefabricated part used to reserve space for the rising well of the rainwater well.

[0040] refer to figure 1 , as a preferred embodiment of the rainwater well lifting device for the road of the present invention, the prefabricated part is a cylindrical sleeve 1, one side of the cylindrical sleeve 1 is sealed, and the other side is open, and the diameter of the opening 11 is greater than the diameter of the wellhead of the well chamber , the material of the cylindrical sleeve 1 is preferably cast iron, and the thickness is between 3mm and 5mm, so that the shape o...

Embodiment 2

[0048] see Image 6 and combine Figure 1 to Figure 5 , the present invention also provides a construction method for a rainwater well raising device on a road, comprising:

[0049] Step 1, after laying down the rainwater pipeline in the lime soil layer 5 below the road structure layer 4, build the first floor well chamber of the rainwater well to the road structure layer 4 at the position of the rainwater well.

[0050] It should be noted that during road construction, before implementing step 1, it also includes surveying and setting out positioning first. Generally speaking, the rainwater pipes of public pipelines are located in the lime soil layer 5 below the road structure layer 4, and are excavated according to the setting out results. Groove, then proceed to step 1, lower the rainwater pipe and carry out masonry work at the position of the rainwater well. The first layer of the well chamber of the rainwater well is built until the road structure layer 4. In this embodi...

Abstract

The invention relates to an underground rainwater well lifting device and a well lifting construction method. The underground rainwater well lifting device comprises a prefabricated part, a temporary fixing structure and a hoisting structure, wherein the prefabricated part is used for reserving a rainwater well lifting layer space; the temporary fixing structure comprises a positioning part used for positioning the position of a well lifting layer and a fixing part connected with the positioning part in a matched mode, and the fixing part is fixed to the prefabricated part; and the hoisting structure is used for lifting the prefabricated part. According to the underground rainwater well lifting device and the well lifting construction method, the prefabricated part is fixed to the reserved well chamber well lifting layer space in a road structural layer through the temporary fixing structure for subsequent rainwater well lifting masonry construction, paving and compacting operation of the road construction structural layer is not affected, and the influence on the road compactness due to the existence of a rainwater well in a traditional construction reverse planing method can be eliminated; and furthermore, an isolation film plays a role in physically isolating the prefabricated part and the structural layer, the hoisting structure can conveniently lift the prefabricated part, construction is convenient, and the cost is low.

Description

technical field [0001] The invention relates to the field of municipal road construction, in particular to a device for raising a rainwater well on a road and a construction method for raising a well. Background technique [0002] At present, the rainwater wells on the road are not connected smoothly with the road surface, and the installation of manhole covers is uneven, and the subgrade around the wells collapses and damages the road. There are serious hidden dangers to driving safety, and it is not conducive to the functional use of the road. At its root, the reason lies in the construction process. [0003] The rainwater wells of general urban public pipelines are often laid first after laying the pipelines, then the rainwater wells are built, and then the pipe trenches are backfilled before road construction. The rainwater wells of public pipelines are mostly brick-concrete structures. Due to the existence of rainwater wells, it is difficult for road rolling equipment ...
