Problems solved by technology

[0003] After the prefabricated parts are prefabricated, they are sent to the construction site for splicing. Most of the construction sites are located in pre-development areas, lacking infrastructure such as roads. From the prefabricated parts factory to the mobile construction site, temporary roads need to be laid for loading and assembly. Box-type box culverts are transported by transport vehicles, so in the layout of prefabricated box-type box culverts, the transportation cost accounts for a large proportion
[0004] The cast-in-place concrete cover plate box culvert needs to be bound according to the steel bars, formwork, concrete pouring, formwork removal and maintenance before the next process can be carried out. The construction conditions are limited, the construction period is long, the process is cumbersome, the construction cost is high, the speed is slow, and the efficiency is low.

Embodiment 1

[0060] Example 1: see Figures 1 to 12 , a mobile improved assembled box culvert formwork, including threaded rods 9, bolts 11 and nuts 12. like Figure 11 As shown in the figure, the front and rear ends of each box culvert body 7 are provided with mutually matched butting convex edges 73 ends and butting grooves 71 ends, and two adjacent mobile improved assembled box culverts are inserted through the butting convex edges 73 ends. The end of the butt groove 71 is connected and fixed end to end.

[0061] The mobile improved assembled box culvert formwork also includes a mobile base table 6, an outer formwork 3, an inner formwork 1, a concave-end formwork 2, and a convex-end formwork 4. The mobile base table is the bottom formwork of the Taozhu box culvert body, and the health and mobile pedestals. The upper end of the mobile base table is provided with the outer formwork, the inner formwork, the concave-end formwork, the convex-end formwork and the built health shed of the Ta...

Embodiment 2

[0097] Example 2: see Figures 3 to 4 , Different from Embodiment 1: the mobile base table 6 can also be the bottom formwork, health care and mobile base of the Taozhu box culvert. The mobile base table is rectangular, and the mobile base table is made of steel plates with a thickness of 20 to 25 mm. The plinths 33 at the lower ends of the outer formwork, the concave-end formwork and the convex-end formwork are provided on the base table corresponding to the lower ends of the outer formwork, the concave-end formwork and the convex-end formwork. There is a sled board 64 on the side, the bottom bracket, the sled board and the lower end of the mobile base platform are fixed by welding. There is a shed pole fixing cylinder 65 for supporting the lower end of the shed pole 13 on the side corresponding to the Taozhu box culvert. The sled board is made of steel plate with a thickness of 20-25mm. The sum of the widths of the plates is less than the width of the mobile base table. The...

Abstract

The invention relates to a movable improved assembly type box culvert template and a construction method thereof, the movable improved assembly type box culvert template comprises a threaded pull rod, a bolt and a nut, and the movable improved assembly type box culvert template further comprises a movable base table, an outer template, an inner template, a concave end template and a convex end template, according to the cast box culvert, construction of a transportation road and prefabrication factory construction do not need to be carried out, casting, maintenance and installation of the box culvert can be completed beside a foundation pit where a box culvert line is arranged, and synchronous propelling can be kept along with propelling of a construction line; the transportation cost can be reduced, the tedious process is simplified, and the construction speed is increased.

Description

technical field [0001] The invention relates to a mobile improved assembled box culvert formwork and a construction method thereof. Background technique [0002] With the continuous improvement of highway and municipal road network, the underground prefabricated box culvert structure in the field of highway and municipal engineering is used more and more in construction, especially in northern China, the annual effective construction time is short. The prefabricated box culvert is now prefabricated in a prefabricated factory and transported to the construction site or cast-in-place concrete cover box culvert in the underground pipeline pit at the construction site. [0003] However, after the prefabricated parts factory prefabricates the products, they are sent to the construction site for splicing. Most of the construction sites are located in pre-development areas and lack infrastructure such as roads. From the prefabricated parts factory to the mobile construction site, t...
