Description

[Technical Field]

[0001] The present invention relates to a method for constructing a coke oven. [Background technology]

[0002] Conventionally, methods for constructing a coke oven are known, as described in the following Patent Documents 1 and 2. In these construction methods, a temporary shed is erected at the planned construction site of the coke oven. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-177846 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-36934 Summary of the Invention [Problem to be solved by the invention]

[0004] It is possible to construct a new coke oven that uses both an existing coke oven and railroad tracks. In this case, if a part of the temporary building is located on the railroad tracks, the railroad tracks will become unusable during construction. This could affect the operation of the existing coke oven.

[0005] The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a method for constructing a coke oven that allows the use of electric rails even during construction. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. <1> A coke oven construction method according to one embodiment of the present invention is a method for constructing a coke oven at a planned construction site that is aligned in a first direction with a railway track that will also be used as an existing coke oven, and includes a first step of installing a temporary shed to cover the planned construction site, wherein a first side of the temporary shed, along the first direction and located on the railway track side of the planned construction site, is equipped with a support pillar that supports the load of the temporary shed, and the support pillar is located on the opposite side of the planned construction site across the railway track in the first direction, and the temporary shed is equipped with a partition wall that divides the interior of the temporary shed into a work space that includes the planned construction site and an aisle space through which fire trucks running on the railway track pass.

[0007] The support pillars are located on the opposite side of the planned construction site from the first direction across the train tracks. Therefore, the support pillars do not obstruct the train tracks. The partition wall separates the interior of the temporary building into a work space including the planned construction site and a passageway space through which fire engines traveling on train tracks pass. Therefore, even when the fire engines are transporting red-hot coke, the partition wall prevents the radiant heat from the red-hot coke from reaching the planned construction site and prevents toxic gases (such as carbon monoxide gas) from the red-hot coke from entering the planned construction site. As a result, electric rails can be used during construction.

[0008] <2> the above <1> In the coke oven construction method according to the present invention, the partition wall may be sandwiched between the planned construction site and the train rail in the first direction, and may include a side wall extending vertically, and a top wall extending from the side wall toward the support pillar along the first direction, and the end of the top wall toward the support pillar along the first direction may be connected to the support pillar.

[0009] The end of the top wall on the support pillar side along the first direction is connected to the support pillar, so that the partition wall is supported by the support pillar and an aisle space is secured.

[0010] <3> the above <2> In the method for constructing a coke oven according to the present invention, the first step may employ the configuration described in claim 2, in which the supports and the partition walls of the temporary building are installed first, and then the remaining parts are installed.

[0011] In the first step, the columns and partition walls of the temporary building are installed first, followed by the rest of the building. This allows the rest of the building to be installed while ensuring passageway space. As a result, the train tracks can be used even while the rest of the building is being installed. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a method for constructing a coke oven that allows the use of electric rails even during construction. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, a method for constructing a coke oven (hereinafter also simply referred to as a construction method) according to one embodiment of the present invention will be described with reference to FIGS.

[0015] (Coke Factory 10) First, a coke plant 10 to which this construction method is applied will be described. As shown in Figures 1 and 2, the coke plant 10 mainly comprises a coke oven 11, a coal loading car (not shown), an extruder (not shown), a guide car (not shown), a fire extinguishing car 12, rail tracks 13, and fire extinguishing equipment 14.

[0016] As shown in Fig. 1, a coke oven 11 produces coke from coal. A coke plant 10 is equipped with two coke ovens 11. The two coke ovens 11 are a first coke oven 11a and a second coke oven 11b. The first coke oven 11a and the second coke oven 11b are arranged side by side.

[0017] As shown in FIG. 2, the coke oven 11 is sandwiched between two platforms 15 . Hereinafter, the horizontal direction in which the coke oven 11 is sandwiched between the two platforms 15 will be referred to as a first direction X. The horizontal direction perpendicular to the first direction X will be referred to as a second direction Y. The two coke ovens 11 are aligned in the second direction Y.

[0018] The two platforms 15 are a first platform 15a and a second platform 15b. Hereinafter, with the coke oven 11 as the reference, the side of the first platform 15a along the first direction X will be referred to as a first side X1 of the first direction X, and the side of the second platform 15b along the first direction X will be referred to as a second side X2 of the first direction X.

[0019] The coal loading car loads coal into the coke oven 11. The coal loading car is located above the coke oven 11. The pusher pushes the coke from the coke oven 11 into the guide car. The pusher is located on the second platform 15b side. The guide car guides the coke to the fire extinguishing car 12. The guide car is located on the first platform 15a.

[0020] As shown in FIG. 1, a fire engine 12 transports coke to a fire extinguishing facility 14. The fire engine 12 travels on rails 13. The rails 13 are aligned in a first direction X relative to the coke oven 11. The rails 13 are aligned on a first side X1 relative to the coke oven 11. The rails 13 extend in a second direction Y.

[0021] The fire extinguishing systems 14 cool the coke. The coke plant 10 is equipped with two fire extinguishing systems 14. One of the two fire extinguishing systems 14 is arranged on a first end side of the railcar rail 13. The other of the two fire extinguishing systems 14 is arranged on a second end side of the railcar rail 13. Examples of the fire extinguishing systems 14 include dry fire extinguishing systems (so-called CDQ) and wet fire extinguishing systems.

[0022] (Temporary Shed 20) Next, the temporary building 20 used in this construction method will be described. As shown in Fig. 2, a temporary shed 20 covers the planned construction site PS of the coke oven 11. In this embodiment, of the two coke ovens 11, the first coke oven 11a is constructed in the presence of the second coke oven 11b. Note that construction includes not only new construction but also renewal.

[0023] The temporary building 20 includes a roof 21, a first side portion 22, a second side portion 23, a partition wall 24, and auxiliary columns 25. The roof 21 is located above the planned construction site PS. The first side portion 22 is located on a first side X1 (the side of the railroad tracks 13) with respect to the planned construction site PS. The first side portion 22 is provided on a foundation 22a that is installed on the ground.

[0024] The first side portion 22 includes a first support column 26, a second support column 27, and an upper wall (not shown). The lower portion of the first side portion 22 is formed by the first support column 26, and the upper portion is formed by the second support column 27 and the upper wall. The first support pillar 26 and the second support pillar 27 (pillars) bear part of the load of the temporary building 20. The first support pillar 26 extends upward from the foundation 22a. The second support pillar 27 extends upward from the first support pillar 26. The upper end of the second support pillar 27 supports the roof 21. A plurality of the first support pillars 26 and the second support pillars 27 are arranged at intervals (intermittently) in the second direction Y. The upper wall is provided continuously in the second direction Y. The upper wall covers the second support pillar 27 in the first direction X. The upper wall is not provided on the first support pillar 26.

[0025] The second side portion 23 is located on the second side X2 relative to the planned construction site PS. The second side portion 23 is provided on a foundation 23a that is installed on the ground. In the illustrated example, the second side portion 23 is provided with a shed 28. However, the shed 28 does not have to be provided.

[0026] The partition wall 24 includes a side wall 29 and a top wall 30. The side wall 29 is sandwiched in the first direction X between the planned construction site PS and the train rails 13. The side wall 29 is located on the first platform 15a. The side wall 29 extends in the vertical direction. The top wall 30 extends from the side wall 29 to the first side X1 (towards the first support pillar 26 along the first direction X). When the partition wall 24 is viewed from the second direction Y, the partition wall 24 has an inverted L shape. An end of the top wall 30 on the first side (towards the first support pillar 26 along the first direction X) is connected to the first support pillar 26 (the upper end of the first support pillar 26 in the illustrated example).

[0027] The partition wall 24 divides the interior of the temporary building 20 into a work space S1 and a passage space S2. The work space S1 is a space that includes the planned construction site PS. The work space S1 is a space between the roof 21, the upper wall, the partition wall 24, and the second side portion 23. The passage space S2 is a space through which fire engines pass. The passage space S2 is open to the outside of the temporary building 20 from between the first supports 26 adjacent to each other in the second direction Y. The auxiliary columns 25 auxiliarily support the load of the roof 21. The auxiliary columns 25 may be omitted.

[0028] (Construction method) Finally, the construction method is explained. The construction method includes a first step of installing a temporary shed 20, a second step of constructing a coke oven 11, and a third step of dismantling the temporary shed 20. The first step and the second step may be partially carried out in parallel. The second step and the third step may be partially carried out in parallel.

[0029] An example of the first step will be described below, although the first step is not limited to this example. First, as shown in Fig. 3, the builder installs the first platform 15a. Next, as shown in Fig. 4, the builder installs the first support columns 26 and the partition wall 24. After that, as shown in Fig. 5, the remaining part of the temporary building 20 is installed.

[0030] As described above, according to the construction method of this embodiment, the first support pillar 26 is located on the opposite side of the planned construction site PS across the train rail 13 in the first direction X. Therefore, the first support pillar 26 does not block the train rail 13. A partition wall 24 divides the interior of the temporary shed 20 into a work space S1 including the planned construction site PS and a passage space S2 through which the fire truck 12 traveling on the railroad tracks 13 passes. Therefore, even when the fire truck 12 is transporting the red-hot coke, the partition wall 24 prevents the radiant heat of the red-hot coke from being transmitted to the planned construction site PS and prevents toxic gases (such as carbon monoxide gas) caused by the red-hot coke from entering the planned construction site PS. From the above, the electric rail 13 can be used even during construction.

[0031] In addition, when two fire extinguishing equipment 14 are placed at both ends of the electric rail 13 as in this embodiment, if the electric rail 13 cannot be used over its entire length, the second coke oven 11b, which is an existing coke oven, will only be able to use one of the fire extinguishing equipment 14. In this case, if the fire extinguishing equipment 14 that can be used by the second coke oven 11b stops for some reason, it becomes necessary to stop the operation of the second coke oven 11b. Furthermore, in this case, if the fire extinguishing equipment 14 that can be used by the second coke oven 11b is a wet type and the fire extinguishing equipment 14 that cannot be used is a dry type, an opportunity to use the dry type fire extinguishing equipment 14 that can increase added value will be lost.

[0032] An end of the top wall 30 on the first support pillar 26 side along the first direction X is connected to the first support pillar 26. Therefore, the partition wall 24 is supported by the first support pillar 26, and the passage space S2 is secured. In the first step, the first support columns 26 and the partition walls 24 of the temporary shed 20 are installed first, and then the remainder is installed. Thus, the remainder of the temporary shed 20 is installed while the passage space S2 is secured. As a result, the train rails 13 can be used even when the remainder of the temporary shed 20 is being installed.

[0033] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0034] For example, the configuration and layout of the coke plant 10 are not limited to those shown in the above embodiment.

[0035] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
