Problems solved by technology

[0005] The installation accuracy of the pre-embedded steel pipes during the construction of the above two methods is not high, and the quality is difficult to guarantee. During the installation process, the surveying engineer needs to do a lot of work to check the coordinates and the top elevation, and the construction period is long, the labor intensity is high, and the labor cost is high.
In addition, the amount of steel required to fix the embedded steel pipe is large, and its strength and rigidity are not guaranteed. Since the concrete pouring can easily affect the vibration of the embedded pipe, it is easy to cause changes in the relative position of the embedded steel pipe, which brings great harm to the equipment installation. difficulty

Embodiment Construction

[0047] In order to further understand the invention content, characteristics and effects of the present invention, the implementation of Xingtai Xuyang 2 million ton coke oven project is taken as an example, and the present invention is further described in detail in conjunction with the accompanying drawings:

[0048] The invention discloses a method for integrally fixing and installing the pre-embedded steel pipe on the top plate of the coke oven foundation:

[0049] Such as figure 2 and image 3 As shown, first according to the diameter and the spacing of the embedded pipe 9 required by the drawing, the positioning hole 10 is processed on the channel steel with a drilling machine, and the horizontal beam fixing frame 1 and the horizontal longitudinal beam fixing frame 2 are manufactured in sections. The positioning hole 10 should satisfy that its diameter is greater than the diameter of the corresponding embedded pipe 9, but the difference must not be greater than the max...

Abstract

The invention discloses an integral fixed installation method of embedded steel pipe on the roof of coal furnace foundation, which is characterized in that channel steel is used as a horizontal cross beam fixed rack and a horizontal longitudinal beam fixed rack, which are welded onto a channel steel post fixed on an embedded iron part, the lower end of the embedded pipe is positioned through a square iron sheet fixed on a multilayered plate, the upper end of the embedded pipe is positioned and elevated by the horizontal cross beam fixed rack and the horizontal longitudinal beam fixed rack via an adjustment pipe coupling, thereby guaranteeing the verticality of the embedded pipe. According to the method, the fixed installation of a plurality of embedded pipes can be completed by means of one-step alignment and adjustment, thus the method is convenient and fast and reduces labor intensity to a great extent, enhances working efficiency, achieves less manpower and lowers expenditure, in addition, the embedded pipes are so fixed and firm that the positioning thereof cannot be impacted by the implementation of other procedures, so the elevation and vertical precision of the embedded pipes are guaranteed.

Description

technical field [0001] The invention relates to a construction method in the civil construction process, in particular to a method for positioning and installing a pre-embedded pipe on the top plate of the coke oven foundation part. Background technique [0002] The structure of the coke oven is similar in design, and is divided into two parts, the coke oven foundation and the furnace body. The coke oven foundation belongs to the civil construction part, that is, the object to be constructed by the civil construction unit. The furnace body is built on the roof of the coke oven foundation and between the resistance walls on both sides. Under the roof of the coke oven foundation is the coke oven basement. After processing, it is transported to the city. Therefore, thousands of embedded pipes must be installed on the top plate of the coke oven foundation to connect the furnace body and the coke oven basement. These embedded pipes are divided into lower nozzles and cleaning pip...
