Problems solved by technology

[0002] In the installation process of the four components of the prefabricated box culvert, the conventional installation process adopts crane hoisting. When the components are hoisted, due to the influence of the position of the lifting point, the vertical fall cannot be completely achieved, or the installation and positioning cannot be achieved when the foundation has a longitudinal slope. One-time precise positioning requires continuous lifting and manual adjustment with crowbars. Repeated operations are required to complete the positioning, and the positioning accuracy is low, which is not conducive to the connection with other prefabricated components in the subsequent construction stage
And when adopting this method, the crane needs to wait on the spot for workers to constantly adjust and put it in place, the crane takes a long time, which increases the installation cost, and when the crowbar is used to put it in place, it is easy to damage the component concrete or foundation concrete, resulting in low installation quality. And the installation efficiency is not high, so that the advantages of rapid construction using prefabricated installation cannot be highlighted

Embodiment 1

[0034] like figure 1 , 3 Among them, a block prefabricated box culvert side wall installation positioning device, it includes:

[0035] Bracket 5, said bracket 5 is used to be placed between the side walls 2 on both sides, and at least one horizontal support structure corresponding to the center of gravity 3 of the side wall 2 is provided on the bracket 5; the bracket 5 in this example is vertically There are scissors support structures in the vertical and vertical directions.

[0036] A jacking cylinder, the jacking cylinder is arranged between the horizontal support structure and the side wall 2, and is used to push the side wall 2 to the installation position;

[0037] The limit beam 4 is fixedly connected with the foundation concrete 18, and the limit beam 4 is used to be placed outside the side wall 2 to limit the installation position of the side wall 2. With this structure, the side wall 2 can be pushed towards the direction of the limit beam 4 by operating the push ...

Embodiment 2

[0047] A construction method using the above-mentioned block prefabricated box culvert side wall installation positioning device, comprising the following steps:

[0048] S1. According to the design position of the side walls 2 on both sides, use the lifting device to hoist the side walls 2 on both sides near the inner side of the design position, usually within 10cm from the side line of the design position; pass through the outer side line of the design position of the side wall 2 Expansion bolts are fixed to install the limit beam 4, and the installation accuracy of the limit beam 4 is within 5mm;

[0049] S2, fixedly install the bracket 5, install the jacking oil cylinder at the end of the horizontal support structure of the bracket 5, the stroke of the jacking oil cylinder will be more than 30cm, the jacking force is 3~5 tons, and the weight of a single side wall 2 is 8 tons. In this example, the structure of the upper push cylinder 6 and the lower push cylinder 8 is pref...

Abstract

The invention provides a positioning device and method for installing block prefabricated type box culvert side walls. The positioning device includes a support, pushing oil cylinders and limiting beams, wherein the support is used for being placed between the side walls on both sides, and one or more horizontal supporting structures corresponding to the centers of gravity of the side walls are arranged on the support; the pushing oil cylinders are arranged between the horizontal supporting structures and the side walls and used for pushing the side walls to the installation position; and thelimiting beams are fixedly connected with foundation concrete, and used for being placed on the outer sides of the side walls to limit the installation position of the side walls. During construction,a lifting device is used for lifting the side walls on both sides to the position near the inner side of the design position, the limiting beams, the support and the pushing oil cylinders are installed, the pushing oil cylinders are pushed, and thus the outer sides of the side walls are in contact with the limiting beams. Through a scheme that the pushing oil cylinders are arranged on the inner sides, the side walls are pushed to the both sides, the limiting beams are arranged, and the positioning accuracy is ensured, the installation quality can be greatly improved, the installation strengthis reduced, and the safety is improved.
