Embodiment Construction

[0015] According to the present invention, a slab girder of a hydroelectric power station is reserved for inserting ribs, such as figure 1 , figure 2 and image 3 As shown, the beam inserting rib groove 4 and the plate inserting rib groove 5 are arranged on the first poured concrete wall 1, and the beam inserting rib groove 4 and the plate inserting rib groove 5 are embedded in the first poured concrete wall 1 to form a groove shape, so that the The construction joint between the plate beam and the wall is moved into the wall body. In the beam inserting rib groove 4 and the plate inserting rib groove 5, there are respectively provided with the post-cast beam 2 and the post-cast plate 3 anchored into the pre-cast concrete wall 1 and poured with the post-cast beam 2 and the post-cast plate 3 to form a whole. Inserting ribs, and between the beam inserting rib groove 4 and the plate inserting rib groove 5 and the first poured concrete wall 1 is provided with the beam inserting...

Abstract

The invention discloses a connection method and a structure for casting a wall body and a plate girder of a powerhouse of a hydropower station by stages. The method and the structure are characterized in that a girder joint bar groove (4) and a plate joint bar groove (5) are arranged on a precast concrete wall body (1); and the girder joint bar groove (4) and the plate joint bar groove (5) are respectively arranged in the precast concrete wall body (1), and are cast with a post-cast girder (2) and a post-cast board (3) so as to form an entire joint bar. Therefore, a groove profile construction seam is formed by moving the construction seam forward to the concrete wall body. According to the connection method and structure provided by the invention, the wall body and the plate girder, which are cast by stages, are connected by using the joint bar, so that the structural integrity is strong. A position of the construction seam of the wall is moved inside the wall body through the joint bar grooves, so that the position of the construction seam is optimized, and the structural reliability is improved. The top faces of the joint bar grooves are expansion cross sections from inside to outside, so that post-cast concrete is beneficial to being tightly and firmly cast. A dismounting-free template is used as a shaping template of the joint bar grooves, so that not only can the difficulty of mounting and dismounting the template due to the fact that 'a die is penetrated by the joint bar' be solved, but also the dabbing treatment on precast wall faces of the joint bar grooves can be eliminated.

Description

technical field [0001] The invention relates to a connection method and structure for staged pouring of a wall body and a slab beam of a powerhouse of a hydropower station, and belongs to the technical field of hydraulic concrete construction. Background technique [0002] Reinforced concrete walls (underwater walls) need to be built to retain water and soil below the flood level or below the ground outside the plant to ensure the safety and normal operation of the plant. The underwater wall is an important flood control and lateral support structure, and at the same time it is the vertical support member of the plate beam structure inside the factory building. During the concrete pouring construction process of the powerhouse of the hydropower station, in order to meet the needs of flood control or construction progress, the underwater wall is generally poured first, and the internal plate beam structure is poured later. Therefore, how to reliably connect the wall and plate...
