Description

Working well construction template for parking apron road and construction method thereof Technical Field The invention belongs to the technical field of road construction, and particularly relates to a working well construction template for a parking apron road and a construction method thereof. Background The road between the airport parking apron and the terminal building is a key infrastructure for ensuring the traffic of various ground service vehicles and heavy freight vehicles. The road has the characteristics of large load, high frequency and strict flatness requirement, and the pavement structure of the road has to have extremely high integrity and uniform bearing capacity. Under such roads, various pipelines such as electric power, communication, drainage, fire control, etc. are often densely distributed, and accordingly, it is necessary to provide a plurality of pipeline operation wells (hereinafter referred to as "operation wells") in a road surface structural layer. The traditional road and working well construction method mainly comprises the steps of sequentially working, namely firstly completing the construction of a well body of the working well or installing the well body to a designed elevation, and then paving and compacting a water stable layer, an asphalt layer and the like of the road around the working well in a layered manner. Therefore, in the prior art, a construction sequence of a first well and a later road is mostly adopted, however, the construction sequence can cause that the main structural layer of the pavement cannot realize integral continuous construction, so that the defects of discontinuous materials, uneven thickness, inconsistent compactness and the like are caused, and finally, a high-strength and complete foundation bearing plate is difficult to form. Disclosure of Invention The embodiment of the invention provides a working well construction template for a parking apron road and a construction method thereof, aiming at solving the technical problem that the bearing capacity of the road surface is reduced due to the construction sequence of a first well and a later road. In a first aspect, an embodiment of the present invention provides a construction method for a working well for a tarmac road, including the following steps: S10, firstly, before the water stable layer of the parking apron road is paved, lowering all pipeline operation wells in an operation range to the elevation at the bottom of the water stable layer to be constructed, using a steel plate to temporarily cover and protect a wellhead, and then continuously and integrally paving and compacting two water stable layers to form a complete and uniform road base structure; S20, after the cement stabilized gravel layer is integrally formed, cutting and removing a water stabilization layer part corresponding to the upper part of the wellhead to expose a construction position, and then heightening the shaft; s30, after the shaft is processed to the target height, temporarily covering and protecting the wellhead by using a steel plate again, and then paving an asphalt lower layer and other design isolation layers of the road in sequence; s40, after the asphalt lower layer and other design isolation layers are integrally formed, cutting and removing the asphalt lower layer and other design isolation layers corresponding to the upper part of the wellhead, exposing the construction position, and then carrying out shaft heightening construction to the elevation of the operation well. Compared with the prior art, the construction method of the working well for the apron road provided by the invention has the advantages that the traditional construction sequence of 'first well and then road' is sublevel, and the construction method of 'first whole paving and then staged perforation and well adding' is initiated. The core benefits of the road pavement paving device are that a cement stable crushed stone layer (a water stable layer) serving as a main bearing layer of a road, a subsequent asphalt lower layer and the like are ensured, and uninterrupted whole paving and compaction can be realized. The defects of discontinuous material paving, difficult uniform operation of compaction equipment and the like caused by the prior existence of the well body in the traditional process are fundamentally eliminated. The final result is that a complete, uniform and high-strength road foundation bearing plate is formed, the severe requirements of the airport parking apron road on the integrity, the flatness and the ultra-high bearing capacity are perfectly met, and the long-term durability and the safety of the road are fundamentally improved from the construction process. In a second aspect, an embodiment of the present invention further provides a construction template for a working well for a tarmac road, including: The outer profile unit comprises a base, a top seat and a middle seat arranged between the base and the top se
