Problems solved by technology
[0003] The construction scheme in the prior art needs a lot of manpower and material resources, the construction efficiency is low, and the construction quality cannot be guaranteed. Long-term closure will also cause the water level of the upstream river to continue to rise, which may cause the upstream river water to flow into the support space. Inside, on the one hand, it affects the construction, on the other hand, geological water enters the unhardened concrete structure, which will cause deformation of the concrete structure and even seriously affect the structural strength

Embodiment Construction
[0041] Various embodiments of the invention will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are denoted by the same or similar reference numerals. For the sake of clarity, various parts in the drawings have not been drawn to scale.
[0042] Such as Figure 1 to Figure 5 As shown, the present invention provides a construction method for inverted rainbow well, which includes the following multiple steps.
[0043] Step 1: In the early stage of construction, two inverted rainbow shaft prefabricated parts 1 and the middle river-crossing pipeline prefabricated structure 2 are made, and the inverted rainbow well foundation pit 3 and the middle river-crossing pipeline foundation pit 4 are excavated;
[0044] In this step, preparations are made for the later construction work, wherein, the step of making two inverted rainbow shaft prefabricated parts 1 and the intermediate river-crossing pipeline prefabric...

The invention relates to a construction method for an inverted rainbow well, which includes the following steps: Step 1: In the early stage of construction, two prefabricated shafts of an inverted rainbow well and a prefabricated structure for a river crossing pipeline in the middle are manufactured, and the foundation pit of an inverted rainbow well and the intermediate crossing are excavated. River pipeline foundation pit; step 2: install the prepared inverted rainbow well shaft prefabricated part in the inverted rainbow well foundation pit, and install the prepared intermediate river crossing pipeline prefabricated structure in the intermediate river crossing In the foundation pit of the pipeline; step 3: docking and assembling the prefabricated structure of the middle river-crossing pipeline with the prefabricated parts of the two inverted siphon well shafts, and performing on-site pouring; step 4: backfilling the foundation pit of the inverted siphon well on both sides of the river and Piping pits. The working efficiency of the inverted rainbow well construction method is greatly improved, the construction quality is greatly improved, and the modular construction makes the construction period greatly shortened and the engineering cost greatly reduced.
Description
technical field [0001] The invention relates to the technical field of inverted rainbow well construction, and more specifically, to a construction method for inverted rainbow wells. Background technique [0002] In the prior art, when constructing an inverted siphon well, it is necessary to intercept the flow upstream, and then excavate the foundation pit of the inverted siphon well downstream of the interception, and excavate the buried foundation pit for crossing the pipeline in the middle, and then excavate the foundation pit of the inverted siphon Steel sheet pile support is carried out in the foundation pit of the inverted siphon well, and artificial pumping is implemented to lower the water level inside the support space, and then the steel frame is erected, the formwork is supported, and the pouring space is formed between the template and the inner wall of the foundation pit of the inverted siphon well. Concrete is poured in the pouring space to form a complete stru...
