Description
Technical Field
The invention belongs to the technical field of water supply and drainage engineering in municipal engineering, and particularly relates to a construction method of an initiation seam of an integral biochemical tank.
Background
The initiation joint (also called a construction joint) refers to a joint formed between the concrete poured before and after the concrete is poured in sections due to design requirements or construction requirements in the concrete pouring process. In the existing construction, a rubber water stop belt is generally adopted in pool construction, the principle is that a water stop product is made by utilizing the characteristic that rubber materials generate high elastic deformation when stressed, and the water stop product is widely applied to water stop of deformation seams and initiation seams in projects such as water utilities, water conservancy projects, hydropower projects, dam and culvert gates, tunnel subways, civil air defense works, basements of high-rise buildings, parking lots and the like.
The rubber water stop is embedded in the deformation joint to be connected with the concrete into a whole when the concrete is poured, so that water seepage and water leakage at the deformation joint of the structure can be effectively prevented, and the functions of damping, buffering and the like are achieved, so that the waterproof requirement in the engineering structure is ensured.
However, in traditional construction, the expansion joint of the bottom plate of the water storage structure leaks, and often the rubber water stop belt is instably installed due to deviation generated in concrete pouring, so that the expansion joint leaks, the post-treatment difficulty is high, and the economic loss is large.
Disclosure of Invention

(2) discontinuous steel bars are arranged on the outer sides of the continuous steel bars, and CB type rubber water stops are fixed at the discontinuous steel bars through supporting frames;
(3) embedding a sealing strip extruded in the concrete body at the joint outside the initiation seam, and filling polysulfide sealant on the surface of the sealing strip;
(4) pouring concrete according to the design requirement, and removing necessary templates after the concrete is solidified.
Further, the support frame comprises a plurality of groups of two horizontally symmetrically-arranged groove-type fixing frames, the embeddable water-stop belt is fixed through the two horizontally symmetrically-arranged groove-type fixing frames, each groove-type fixing frame comprises an upper row of steel bar frames and a lower row of steel bar frames, a gap between the upper row of steel bar frames and the lower row of steel bar frames is used for clamping the embeddable water-stop belt, and the upper row of steel bar frames and the lower row of steel bar frames are connected through vertical steel bars; four angles of steel-bar framework run through and are provided with perpendicular steel-bar framework horizontal reinforcement group, go up steel-bar framework upper end frame middle part and steel-bar framework lower extreme frame middle part and be provided with perpendicular and steel-bar framework's horizontal reinforcement, and the horizontal reinforcement at steel-bar framework middle part is connected from top to bottom to vertical reinforcing bar.

Has the advantages that:
(1) the EP type rubber waterstop has the functions that: set up back of the body between bottom plate expansion joint and bed course and paste formula rubber waterstop, can combine to form a whole with bottom plate concrete body when concrete placement. When the concrete member expands with heat and contracts with cold due to foundation deformation or temperature, and the induced joint is taken as the weak point of the stress of the structure, the lower layer concrete has the possibility of having cracks, the EP type rubber waterstop effectively isolates the underground water by utilizing the characteristics of elastic deformation, corrosion resistance, durability and the like, and the underground water is prevented from immersing into the concrete body and corroding the reinforcing steel bars of the bottom plate body.
(2) Continuous reinforcing bar main function guarantees the wholeness of the whole structure of bottom plate, increases the intensity of expansion joint department structure, if the whole disconnection of lower floor's reinforcing bar, then stretch out and draw back out no reinforcing bar, can't satisfy structural strength needs. The PVC pipe is sleeved at the expansion joint on the continuous steel bar and is isolated from the concrete, the section is the free end of the steel bar, and the free section is easier to break than a common deformation joint, so that the release of the structural internal stress is realized, and the requirement of structural deformation in a continuous section of length can be met under the stress action after the fracture and the whole section of the steel bar.
(3) The interrupted reinforcing steel bar has the main functions: and arranging discontinuous steel bars on the upper layer of the initiation joint to enable the initiation joint to serve as a weak point of structural stress, and inducing the structure to break at the initiation joint when the concrete member expands with heat and contracts with cold due to foundation deformation or temperature.
(4) Sealing strips: the sealing strip is arranged at the position where the top of the initiation seam is contacted with the water surface, and can play the roles of water prevention, sealing and buffering.
(5) The rubber water stop is effectively fixed through the support frame, so that the rubber water stop is prevented from displacing when concrete is poured, the correct position of the water stop in the concrete is ensured, the interface part is kept flat, the water stop is prevented from rolling and twisting, and the water pool is not leaking during the construction of an initiation seam.
