[0040] Precast concrete caisson assembly at fabrication site
[0041] The underground pipe network inspection well of the present invention adopts the method of caisson, and the caisson is assembled by various concrete components. The components installed in the caisson from bottom to top are: base assembly, middle part 6, upper neck part 7, until the upper neck part 7 is installed, and the manhole cover 9 is covered on the mouth of the neck to form an inspection well (see figure 1 ). The middle part 6 and the upper neck tube part 7 make prefabricated parts of various specifications and shapes formed by an anti-corrosion inner mold, an outer mold, and a reinforced dragon at the production site. Inner mold is the lining 8 of inspection well, and lining adopts anti-corrosion fiberglass or plastic material, and this example adopts fiberglass material. Concrete is then poured on the prefabricated part, and the inner liner 8 is connected with the concrete as a whole. Vibrated unt...

The invention discloses an underground pipe network inspection well concrete component and a rapid well sinking method of the component. The underground pipe network inspection well concrete component comprises a concrete upper neck cylinder part, a concrete middle segment part and a concrete base component. A cylinder opening of the concrete upper neck cylinder part is matched with a concrete well cover; the concrete middle segment part is arranged between the concrete upper neck cylinder part and the concrete base component and is inserted and connected with the concrete upper neck cylinder part and the concrete base component through sealing parts and wedge openings to form an inspection well. The rapid well sinking method of the component comprises the steps of performing excavation, taking soil, sinking well, assembling parts, and connecting the inspection well with a pipeline. Inspection well assembling parts are prefabricated in a manufacturing site, concrete casting or well building through bricking is not required to be carried out in the construction site, and the field construction time is greatly shortened; the assembled type well sinking method is adopted by the inspection well, soil taking and well sinking are carried out at the same time, soil taking is carried out in the well, and the ground foundation disturbance is reduced; enclosure of steel plate piles or timber piles is not needed, the construction speed is high, the working efficiency is high, and the cost is low. The leakage and corrosion prevention performance of the inspection well is improved through a corrosion-prevention lining of the component.
Description
technical field [0001] The invention relates to an underground pipe network inspection well, in particular to an underground pipe network inspection well formed by a rapid caisson method in which a concrete assembly is excavated to take soil and sink the assembly. Background technique [0002] With the continuous development of urban construction, the task of construction and renovation of underground pipe network is very heavy. There are usually three construction methods for newly built or renovated underground pipe network inspection wells in cities: the overall caisson construction method, the ground excavation pouring concrete well construction method and the ground excavation brick well method. [0003] Integral caisson construction method: it is to pour concrete wells on the ground. Generally, it takes 28 days of curing period for the concrete to reach strength, and then the ground can be excavated to implement caissons. If the depth of the caisson exceeds 5 meters, ...
