Vertical wall pouring construction method and pouring construction device

technical field

The present invention relates to the technical field of wall pouring construction, in particular to a vertical wall pouring construction method, and also to a vertical wall pouring construction device.

Background technique

With the continuous advancement of my country's urban infrastructure construction, underground structural projects such as underground rail transit and underground comprehensive pipe corridors are gradually emerging. The underground rail transit station is usually a two-story or three-story double-column three-span rectangular frame island station, which is constructed by the open cut method. The height of each wall in the standard section of the structure is 4.0m-5.9m, the length is 16.0m-24.0m, and the width is 0.7m-0.9m; and because the underground rail transit station is placed in the soil layer and the design service life is 100 years, The durability, bearing capacity, service life and use function of the main structure have particularly high requirements on the anti-seepage ability, and special concrete construction methods are required for construction.

At present, the wall formwork of the main structure is usually assembled with glued formwork or large formwork with single-sided steel formwork. Based on the high wall height of the main structure, long construction unit length, large wall area and narrow wall thickness, when the concrete pouring construction of the main structure wall is carried out, it will: 1. Due to the drop height of the concrete mixture Large, so that the coarse aggregate will accumulate and segregate within the range of 2000mm at the bottom of the wall. After being vibrated by the vibrating rod, the interior and surface of the concrete will have cavities and honeycombs due to the lack of cement slurry that is not fully coated and filled with the coarse aggregate and the skeleton gap; 2. Due to the narrow thickness and high height of the wall of the main structure, and the dense layout of the main steel bars, the vibration time of the concrete is too long, and the vibration is uneven, resulting in missing vibration, resulting in the wall concrete after the formwork is removed. Bubbles appear on the exposed surface, mold expansion, coarse aggregate sinks, segregates and delaminates, and looseness and density lead to the formation of water seepage channels inside the concrete. Once the groundwater on the side wall of the foundation pit infiltrates into the concrete along the seepage channel, the corroded steel bars on the wall cause the volume to expand, causing the concrete to crack and leak out of the wall of the main structure, which not only affects the perception of the station wall, but also reduces the The bearing capacity of the structure and the reduction of the concrete's own waterproof capacity will eventually lead to a reduction in the service life and use functions of various facilities in the rail transit structure space, deteriorating the operating conditions of rail transit; at the same time, it will also increase the water seepage control during long-term operation and maintenance of rail transit cost.

As shown in Fig. 1, the construction method of pouring vertically to the wall of the present embodiment includes the following steps: on the formwork panel 11, a plurality of work windows 13 are set along the height direction and work window doors 14 are set, and the formwork panel 11 is installed on On the support frame 12, the support frame 12 is installed on the bottom plate concrete layer 400 that has been formed, so that the formwork panel 11 is arranged opposite to the vertical wall of the foundation pit 300 and forms a cavity for concrete to be poured, and then the formwork panel 11. The space area on the outside is provided with a feed hopper 21 at the input end and a main pipe 22 arranged vertically and a branch pipe 23 connected to the output end of the main pipe 22 at the input end. A plurality of branch pipes 23 are arranged along the height direction. Cloth and extend into the working window 13 at the corresponding height, and set the control valve 25 for controlling the delivery volume of concrete in the branch pipeline 23, so as to complete the installation of the construction device for pouring vertically to the wall; by controlling the concrete delivery pump and Adjust the control valve 25 to pour concrete into the feed hopper 21, so that the concrete flows into the sub-pipe 23 of the corresponding height and pours from the working window 13 of the corresponding height to the concrete layer in the cavity to form a new concrete layer. After the concrete layer pouring is completed, the sub-pipe 23 of the corresponding height is taken out from the working window 13 of the corresponding height, and the new concrete layer is vibrated evenly after being extended from the working window 13 of the corresponding height through the vibrating device, so that the concrete is moved from the low Pour into the cavity layer by layer until the height distance between the liquid level of the concrete layer and the bottom of the top working window 13 is less than 1/3 of the height of each layer of concrete layer, the top working window door 14 will The upper working window 13 is covered; the above-mentioned layered pouring method is adopted, and the concrete is poured into the cavity from the opening at the top of the formwork panel 11 through the concrete delivery pump, until the liquid level of the concrete layer in the cavity is in line with the design of the wall. The heights match, and the concrete layer in the cavity is formed, thereby completing the pouring construction of the wall units; in the above-mentioned manner, the pouring construction of the wall units is carried out one by one along the extension direction of the wall, until the total length of all wall units is in line with the design of the wall The lengths match to complete the pouring construction of the wall. In the vertical wall pouring construction method of the present invention, a plurality of working windows 13 are provided along the height direction on the form panel 11, and a plurality of sub-pipes 23 are installed in the space area outside the form panel 11, and the plurality of sub-pipes 23 are arranged along the height direction and extend into the working window 13 at the corresponding height, and then by controlling the concrete delivery pump and adjusting the control valve 25, the concrete is poured into the feed hopper 21, and the concrete is poured from the sub-pipes 23 at different heights. pouring into the cavity, so as to realize the layered pouring of the wall, the concrete falls from the outlet of the branch pipe 23 to the concrete layer that has been poured before, and the feed pouring adopts layered pouring from bottom to top, corresponding to the pouring plane. The corresponding working window 13 is poured to reduce the falling height, thereby avoiding the accumulation and segregation of the coarse aggregate in the concrete at the bottom layer due to the large falling height of the concrete, and the generation of air bubbles caused by the material falling from a high place and bringing in too much air.
