Embodiment Construction

[0029] Examples see figure 1 , figure 2 , image 3 As shown, this pre-sealed structure of the post-settlement cast belt is characterized in that: the settlement post-cast belt is set at the place where the structure has not yet settled stably, and the bottom surface of the settlement space 2 inside the settled post-cast belt is laid with a post-cast belt formwork 1, A reinforcement cage is arranged in the settlement space 2, and a mortar layer 3 is laid along the surface of the cast belt after settlement and the two edges, and a concrete cover plate 4 is laid on the surface of the mortar layer 3, and on the concrete cover plate 4, from bottom to bottom Connect the transition layer, the waterproof layer, the concrete protection layer 8 and the backfill soil 9 sequentially; reserve a concrete pouring hole 13 on the concrete cover plate 4, and the concrete pouring pipe 11 is vertically connected to the pouring hole 13, and the diameter of the pipe is 300mm. The spacing is 4000...

Abstract

The present invention relates to a post-subsidence pouring belt pre-sealed structure and a construction method thereof. A post-subsidence pouring belt is constructed at the position of the structure, where the subsidence is not stable, a post-pouring belt moulding board is laid on the bottom surface of the subsidence space in the post-subsidence pouring belt, a steel reinforcement cage is arranged in the subsidence space, a mortar layer is paved along the upper surface and both edges of the post-subsidence pouring belt, and a concrete cover plate laid on the mortar layer is connected with a transition layer, a water-proof layer, a concrete protection layer and backfilled soil in order; a concrete-pouring hole is reserved on the concrete cover plate, a concrete-pouring tube is vertically connected with the concrete-pouring hole, the lower tube orifice of the concrete-pouring tube is inserted into the subsidence space, and the upper tube orifice of the concrete-pouring tube is exposed outside the backfilled soil and temporarily sealed and wrapped by the tube top; at the position of the concrete-pouring tube, the water-proof layer and the concrete protection layer are extended upwards to wrap the concrete-pouring tube, and fixed outside of the upper tube orifice of the concrete-pouring tube. The present invention resolves the problem that the sealing construction at the joint of a subsidence belt structure is carried out in advance, and therefore the present invention can not only greatly shorten the construction period and reduce the construction cost, but also satisfy the force-bearing requirement on the structure and ensure the quality of the project.

Description

(1) Technical field [0001] The invention relates to a concrete building structure and a construction method thereof, in particular to a concrete building structure with different floor heights and different settlement zones and a construction method thereof. (2) Background technology [0002] In the construction of construction projects, due to the different design of the height of the engineering structure, the settlement velocity at the connection of different heights of the structure is also different. If concrete is poured at the same time, engineering hidden dangers such as subsidence or cracks may occur at the joints of the structure due to different settlements, and the structure cannot be guaranteed to meet the design stress requirements. The conventional construction method is to pour concrete into the settlement space after the settlement of the structure is stable. As a result, the structure at ±0.00 cannot be closed together with the structural floor, and the wa...
