Each big head bolt 14 is also provided with a water stop 5. The large-head bolts 14 are provided with not less than 4. The steel sheet 2 comprises a rotatable blocking steel sheet 9 and saw teeth 10, wherein a rotating shaft is arranged on the rotatable blocking steel sheet 9, and the saw teeth 10 are arranged on the lower portion of the rotatable blocking steel sheet 9. The triangular support 8 is a right triangle. A slideway 11 is arranged on one bottom edge of the triangular bracket 8; the buckle 3 comprises a connecting block 12 and a fastening bolt 13, wherein the connecting block 12 is arranged on the slideway 11 and can slide in the slideway 11; the fastening bolt 13 is arranged below the connecting block 12, and the reinforcing steel bar 7 is installed on the connecting block 12. The triangular support 8 and the Hafen groove 1 are arranged at a certain angle. C-shaped channel steel is further arranged on two sides of the Halfen groove 1.
The construction method of the novel Hafen groove provided by the embodiment of the invention comprises the following steps:
after the binding of the reinforcing steel bars of the pipe gallery wall is finished, selecting a Hufen groove installation position according to the early-stage design requirement;
inserting the big end bolt behind the Hafen slot into the reinforced wall body, and determining whether the installation is bilateral or not according to the requirement:
if the installation is unilateral, the large-head bolt with the water stop sheet is directly bound with the main body steel bar, and the four triangular supports are inserted into the wall body steel bar;
if the installation is bilateral, the C-shaped channel steels on two sides of the Hafen channel are installed by using a level gauge after the large-head bolt is ensured to be vertical to the wall body, and the triangular supports at four corners are installed in the same step as the single-side installation;
after the triangular support is inserted into a steel bar wall body, the buckles can move on the triangular support, when a proper steel bar is selected for fixing, the connecting blocks of the buckles are moved to enable the buckles to be tightly buckled with the steel bar, after the buckles at the four corners are completely fixed, whether the hafen grooves are vertical or not is observed, and the next step can be carried out after the hafen grooves are vertical;

and finally, after the Hafen groove is closely contacted with the template and is vertical to the ground, concrete pouring is carried out.
The current installation procedure is to use spikes to fix the holes on the template through holes reserved on the surface of the embedded parts while supporting the template of the side wall before the haufen slot. A long nail and template should be used for each cavity in which a part is embedded. During the embedding of the embedded part, the surface of the embedded part and the surface of the template should be tightly connected. After fixing the embedded parts with the formworks, it is checked whether the embedded parts are perpendicular to the ground before casting concrete. The concrete adhering to the outer surface of the embedded component is cleaned to expose the surface. The contents of the can were removed. After the embedded part is fixed by the formwork, it is checked whether the embedded part is perpendicular to the ground before concrete is poured. After the embedded part is installed by the Hafen slot inspection, the embedded part is subjected to self-inspection and hidden record. After passing the self-test, it should be reported to the supervisor to accept the embedded part. Only after passing the acceptance can the next step be performed. During the embedding of the toothed hayfen slot, the surface of the embedded part and the surface of the template should be tightly connected.
The hafen groove is fixed on the reinforcing steel bars through bolts and is connected with the wall reinforcing steel bars corresponding to the positions of the clamping buckles on the triangular supports, and the clamping openings can be adjusted in position through the connecting blocks through the slide ways to ensure that the clamping buckles are connected with the wall reinforcing steel bars at the most proper positions, so that the hafen groove is finally connected with the template tightly. When the pipeline bracket is erected at the later stage, the bracket can penetrate through the rotatable blocking steel sheet from the lower end of the Hafen groove, and can be fixed on the Hafen groove when reaching a preset position. In order to prevent the water seepage of the bolt after the wall pouring is finished, the bolt is provided with a water stop sheet. The water stopping function is added to the hafen groove.
The invention aims to improve the stability of the halan tank and facilitate later use. According to the design, triangular supports are additionally arranged at four corners of the Hafen groove, and the triangular supports are provided with slide fasteners (shown in figure 2), so that bayonets are fixed on wall body reinforcing steel bars during installation, and the stability is improved; secondly, a water-stopping steel sheet (as shown in figure 3) is arranged on the long bolt at the back of the Hafen groove, so that the water seepage of the through-wall bolt is prevented. And a rotatable blocking steel sheet (as shown in figure 7) is arranged in the hafen groove, so that the bracket arm support is more convenient and stable to mount at the later stage.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
