[0002] Conventional municipal road power well construction involves on-site investigation, surveying and setting out, foundation pit excavation, local foundation pit support, foundation construction, steel bar construction, template assembly, concrete pouring, curing and demolding. The entire construction process of the power well is relatively complicated, and the investment in manpower, materials and machines is relatively large. The construction site has high requirements, the construction efficiency is low and the process cost is high. As the depth of the foundation pit continues to increase, the support investment of the foundation pit is followed up in time. Due to the uncertain geological survey, soil changes and the influence of the surrounding environment, the construction safety risk factor is high. The construction depth of the municipal power well is 2.5m-3.2m, and the length of the power well varies from 6m to 12m. Because the secondary trunk roads of municipal roads are relatively narrow, the interval is usually 6.5m-9.5m. In addition, the road cannot be fully closed for construction, and only half of it is open for construction and half of it is open. If the road is under construction in the main urban streets, it is more complicated for various vehicles and personnel to come and go. Due to the unknown underground pipelines of the old road reconstruction. Various types of power pipelines, gas pipelines, water pipes, culverts, and rainwater and sewage pipes are relatively concentrated, which seriously affects the construction progress and safety during the exploration and excavation process.

Among them, usually the municipal road power well is divided into various forms such as straight well, three-way well, four-way well, etc., and the intersection 5 can be designed. The intersection 5 is a template design of the interface, which is folded and fastened by rotating buckle plate, and the construction operation is convenient. The molding effect is good.

[0019] By adding the latch connecting rod 2, the casting plate 3 can be better supported and fixed, ensuring stability during casting. At the same time, the latch connecting rod 2 is fixedly arranged on the support frame 1 by the latch, which greatly improves the convenience during installation. The structural design of the telescopic support rod 4 allows the telescopic rod 42 to support the inner plate 32 when the telescopic part 41 is extended, ensuring the stability of the inner plate 32 during casting and subsequent concrete solidification. The bottom support rod 7 provides support to the latch connecting rod 2 externally. Generally, the bottom support rod 7 adopts a 45° oblique support. At this point, both the inner plate 32 and the outer plate 33 are well supported. Generally, the telescopic part 41 of the telescopic support rod 4 can be selected as a hydraulic tappet or a threaded telescopic rod. The hydraulic tappet is extended or shortened by hydraulic flow, and the threaded telescopic rod is extended or shortened by rotation and then driven by the thread. Similarly, it is preferred that a bottom support rod telescopic part is provided in the middle of the bottom support rod 7, and the bottom support rod telescopic part is a threaded telescopic rod 71.

[0020] In order to facilitate the connection between the telescopic rod 42 and the inner plate 32, the following solution is preferred: the free end of the telescopic rod 42 is provided with a telescopic rod buckle 43, and the telescopic rod buckle 43 is snap-fitted with the bayonet on the inner plate 32.

After the measurement and layout of the construction site is completed, the excavation and drainage of the foundation pit and the pouring of the foundation are carried out. According to the measurement and layout, the steel bars are installed and tied. Then the size of the power well is measured and the support frame 1 is installed. Before the installation of the support frame 1, the various bolt parts need to be pre-buried on site. Then the template is clamped. After the installation of the outer plate 33 and the inner plate 32 is completed, the telescopic support rod 4 is installed. Because the construction of the power well is an integrated construction, the secondary top mold construction process is not used. After the installation of the lower template and its support is completed, the upper top steel bar needs to be installed, and the template is combined after the steel bar installation is completed. The upper top template is connected with the rotating part of the inner plate 32, which is a 180° rotating combination connection.

After the steel bars and the casting plate 3 are installed, the fixings are tightened, and the connection of the telescopic support rod 4 is checked in particular. Ensure that the force transmitted by various loads can be withstood during the concrete pouring process. The last step is to install the bottom bracket and support, which is a pre-made socket-type slot connected and fixed with the column fastener. Through the control of the telescopic member in the middle of the rod, the lower support connection is effectively performed.
