Description

Basic concrete structure of valve chamber and valve chamber embedding method using same {omit}

The present invention relates to a valve chamber buried in the ground used for maintenance of water and sewage pipes, and in particular, in the basic concrete structure installed for preventing the settlement of the valve chamber on the floor on which the work is carried out, Even after casting in the field, before the curing of the concrete (hardening), the valve chamber is supported by the girder steel constituting the foundation concrete structure, thereby improving workability according to the laying of the valve chamber, and at the same time, significantly reducing work time. The present invention relates to a basic concrete structure of a new valve chamber and a method of laying a valve chamber using the same to solve traffic disturbances and local civil complaints and further reduce construction costs.

The pipelines used for the upper and lower sewage and water pipelines are buried and used in the ground. In order to effectively control various types of fluids flowing in the pipelines, the pipelines have water separator valves, air valves, pressure reducing valves, earth valves, Hydrants, flowmeters, pumps, and other facilities (hereinafter referred to as "valve facilities") are provided and these valve facilities are arranged and managed in the valve chamber.

The valve chamber is provided with a manhole (cover) at the upper part, the worker enters the valve chamber through the manhole is formed a space for the operator to work for maintenance, such as to control the flow rate of the pipeline, the number of steps.

In addition, the valve chamber is a space used as an entrance and exit for equipment and personnel for the maintenance and repair of underground pipelines or in the event of leakage leakage of the pipelines.

The size of the valve chamber as described above varies depending on the size of the pipeline and the installation environment of the valve facility, such as box type, width and length width 1.5 meters, height 1.5 meters, and large size 7 meters, width 2 meters, height 1.9 meters. It is designed in size, manufactured at the factory, and transported to the construction site for installation.

When embedding the above-mentioned valve chamber in the ground, in order to prevent the settlement of the valve chamber, the foundation concrete is installed at the bottom of the trench and the valve chamber is placed on the foundation concrete.

In the conventional case, two methods of installing the foundation concrete are known.

One is to install the foundation concrete on site and cure it, and then install the valve chamber on the cured foundation concrete. In this case, there is a curing time of the foundation concrete, there is a problem to delay the work by that time. Especially in winter, the curing time of concrete is longer, which delays the work. Moreover, when laying the roadway by digging the road, the curing time of the concrete greatly interferes with the traffic. Accordingly, if the valve chamber is placed before the concrete is solidified, the valve chamber may be settled into the concrete by its own load, which may adversely affect the pipeline, causing the pipeline to be deformed.

The other is to install the valve chamber through factory-made foundation concrete (precast concrete). This has advantages of simple construction because it uses pre-made concrete, which shortens workability and installation time. However, the size (floor width) of the manufactured valve chamber can be different for each work site and customized valve chambers of various sizes can be customized. As the supply is made, it is costly to produce the basic concrete for each size.In particular, since the makers of valve chambers do not manufacture concrete together, there is also a problem in that they deal with it one by one. It is a reality.

The present invention has been made to solve the problems of the prior art as described above, the problem to be solved by the present invention, after the concrete is poured in the field on the ruptured floor can be installed even before the concrete is cured. It is to provide a basic concrete structure of the valve chamber and a method of embedding the valve chamber using the same to form a new basic concrete structure so that not only workability but also greatly shorten the installation time of the valve chamber can improve construction performance and reduce construction costs. .

In addition, the present invention by the valve chamber is integrated with the basic concrete structure to prevent the settlement of the valve chamber and the valve chamber is lifted from the basic concrete structure by buoyancy to fundamentally solve the phenomenon of rupture and leakage due to pipeline deformation It is to provide a basic concrete structure of the valve chamber so as to bury the valve chamber using the same.

The problem solving means of the present invention, in the base concrete structure is formed in the bottom of the trench to support the valve chamber,

The bottom of the valve chamber is supported on both sides of the bottom of the valve chamber and placed side-by-side with a certain height so as to fill the poured concrete, and both sides of the side-by-side arranged steel pedestal concrete placed between the two steel pedestal The installation of the blocking panel to prevent the installation, and by placing the concrete as much as the height of the steel beam in the filling space formed through the both sides of the steel plate and the blocking panel to form a foundation concrete structure.

The section steel support is formed by any one of the H-shaped steel or 'c'-shaped channel formed of a web and a flange is filled with poured concrete is characterized in that the concrete is integrated with the H-shaped or' c'-shaped channel.

At least one subsidiary steel is installed at the bottom of the valve chamber, and the subsidiary steel is embedded in the concrete, and the valve chamber and the base concrete structure are integrated.

The auxiliary steel is characterized in that the H-shaped steel or 'c' shaped channel consisting of a web and a flange.

Seating the valve chamber through a steel beam butt;

Characterized in that it comprises the step of performing the pipe work of the pipeline and the valve facility in the valve chamber and then backfilling.

In addition, the present invention is a method for embedding the valve chamber in the ground using a base concrete structure,

Installing at least one auxiliary section steel at the bottom of the valve chamber;

Digging to the depth where the valve chamber is buried in the ground to form the bottom of the trench;

Arranging sidewalls of the steel beams having a constant height so as to chop the excavated bottom and fill the concrete being supported and placed on both sides of the bottom of the valve chamber;

It has the effect of greatly shortening. In particular, when digging a road and laying a valve room, it is possible to minimize the traffic interruption by shortening the working time and to minimize friction caused by civil complaints of neighboring locals due to the time required for construction.

In addition, the present invention is to prevent the sinking of the valve chamber is the biggest reason for installing the valve chamber through the base concrete structure. Therefore, the present invention prevents subsidence of the valve chamber by the concrete that is poured through the steel beam support constituting the foundation concrete structure.

In addition, according to the present invention, as the concrete is cured by the subsidiary steel installed at the bottom of the valve chamber is embedded in the concrete, the valve chamber is integrated with the basic concrete structure through the subsidiary steel. This can prevent the valve chamber from being floated apart from the basic concrete structure by the buoyancy of water.

That is, the inner space of the valve chamber is closed and is buried in the form of one large floating structure. When the rainwater is infiltrated and immersed around the outside of the buried valve chamber, the valve chamber may be floated. This causes the valve chamber to float, affecting the pipeline connected thereto, so that the pipeline is damaged. Therefore, it is possible to protect the pipeline by preventing the valve chamber from floating as it is integrated with the basic concrete structure that serves as a weight structure by the auxiliary steel.

As an embodiment of the present invention, the valve chamber 100 shown in FIG. 1 has various valve facilities installed therein, and includes a box-shaped enclosure 102 connected to a pipeline and an upper portion covering the upper portion of the enclosure 102. A cover 104 and a manhole 106 formed at one side of the upper cover 104 to enter and exit the worker are formed. In the figure, reference numeral 108 denotes a hole through which the pipe passes.

In the present invention for embedding the conventional valve chamber 100 constructed in the ground as described above, the foundation concrete structure 10 is installed on the ruptured bottom 60 as shown in Figs. .

The basic concrete structure 10 is composed of a section steel support 20, the blocking panel 30 and the concrete 40.

The section steel support 20 has a predetermined height and has a predetermined width so as to support both sides of the bottom (bottom outer surface) of the valve chamber 100 and are arranged side by side on the floor 60, both ends of the both section steel support 20 The blocking panel 30 is installed to prevent the concrete 40 to be poured between the both steel support 20 is installed, the shape steel in the filling space formed through the both steel support 20 and the blocking panel 30. The concrete 40 is poured by the height of the pedestal 20 to form the basic concrete structure 10.

The blocking panel 30 may be a metal panel (Eurofoam) or a panel in the form of plywood. In the case of a metal panel, it can be connected to the section steel support 20 by welding or the like, and the panel of the plywood form is connected to the section steel support 20 through a wire. In order to prevent the fall (falling) to the outside of the blocking panel 30 to the soil filling work to be put on the pressure when pouring the concrete 40 to maintain the airtightness and at the same time to prevent the fall.

As shown in FIG. 4, the shaped steel support 20 is formed of H-shaped steel so that the poured concrete 40 is filled between the web 21 and the flange 22 of the H-shaped steel 20. (H-shaped steel) and the concrete 40 is preferably integrated. That is, the valve chamber 100 is installed through the upper portion of the both steel support 20, the load of the valve chamber 100 is concrete between the web 21 and the flange 22 of the steel support 20 After the concrete 40 is filled by being filled with 40, the load is also transmitted to the concrete 40 so that the concrete 40 supports the valve chamber 100 together with the shaped steel support 20. It is to be able to effectively prevent the settlement of the seal (100).

Meanwhile, as shown in FIG. 5, the shaped steel support 20 may be configured as a 'c' shaped channel 20A instead of the H shaped steel. Accordingly, after the concrete 40 is cured by filling the concrete 40 in the 'c' shape of the channel 20A, the load is also transferred to the concrete 40 so that the 'c' shaped channel 20a is provided. In addition, the concrete 40 supports the valve chamber 100 so that the settlement of the valve chamber 100 can be effectively prevented.

In the case of the H-shaped steel supporting the valve chamber 100 in the above, the area of the valve chamber 100 is wide because the weight is heavy, and in the case of the 'c'-shaped channel 20A, the area of the valve chamber 100 is It is preferable when the weight is narrow and light.

Meanwhile, concrete 40 in which the auxiliary steel 70 is poured by installing at least one auxiliary steel 70 on the bottom (bottom outer surface) of the valve chamber 100 is illustrated in FIGS. 7 to 9. ) And the valve chamber 100 may be integrated with the basic concrete structure 10.

That is, in the state where the concrete 40 is poured (pre-curing state) through the concrete filling space formed by both the steel beam support 20 and the blocking panel 30 as shown in FIG. 20) the auxiliary section steel 70 protruding from the bottom of the valve chamber 100 is naturally buried in the concrete 40 and is buried as the concrete 40 is cured by the auxiliary section steel 70 embedded therein. The valve chamber 100 is integrated with the basic concrete structure 10.

As described above, the valve chamber 100 becomes one body with the basic concrete structure 10 so that the valve chamber 100 can be prevented from floating by buoyancy of water.

As described above, the valve chamber 100 is closed in an inner space and is buried in the form of one large floating structure. When the valve chamber 100 is flooded with water, the valve chamber 100 is flooded. ) Can be floated. This causes the valve chamber 100 to float, thereby affecting the pipe line connected thereto, thereby placing the pipe line in an environment where the pipe line is broken. Therefore, the valve chamber 100 may be integrated with the basic concrete structure 10 serving as the weight structure by the auxiliary steel 70 to prevent the floating of the valve chamber 100 to protect the pipeline.

The auxiliary steel 70 is preferably formed of any one of the H-shaped steel consisting of the web 71 and the flange 72 or the 'c'-shaped channel 20A as described above. This is because there is no fear to be separated from the concrete 40 by the cross-sectional structure of the H-shaped steel '' 'channel (20A).

The method of embedding the valve chamber using the basic concrete structure of the valve chamber configured as described above is as follows.

First, as shown in (a) of FIG. 6, the bottom of the trench 60 is formed by digging to the depth where the valve chamber 100 is buried in the ground. In this step, the trench bottom 60 is flattened.

Next, as shown in (b) of FIG. 6, the ruptured bottom 60 is compacted, and both bottoms of the valve chamber 100 are supported on the bottom 60 so as to fill the concrete 40 to be poured. It is a step of arranging the beams 20 having a height side by side. Since the section steel support 20 has its own load, no separate fixing means is required.

Next, as shown in (c) of Figure 6 on both ends of the side beams 20 arranged side by side to install a blocking panel 30 to prevent the concrete 40 to be cast between the two steel beams 20 It's a step. The installation height of the blocking panel 30 is preferably the same as the height of the section steel support 20. The blocking panel 30 is to form a filling space of the concrete 40 together with the steel plate 20, it is preferable to maintain both ends and airtightness of the steel plate 20 and not be conducted at the same time. For example, by filling the soil around the blocking panel 30 from the outside to prevent airtightness and conduction when the concrete 40 is poured.

Next, as shown in (d) of FIG. 6, the concrete 40 is poured into the filling space formed through the both steel support 20 and the blocking panel 30 by the height of the steel support 20 to form the foundation concrete structure 10. ) To form. The base concrete structure 10 is formed through this step, and is filled between the web 21 and the flange 22 of the shaped steel support 20 of the concrete 40 to be poured, thereby curing the shaped steel support 20. It is integrated with

Next, as shown in (e) of FIG. 6, the valve chamber 100 is seated through the shaped steel support 20. The valve chamber 100 is to be placed on the upper side of the bottom of the steel beam 20 is arranged side by side by using the equipment to the valve chamber 100. Accordingly, since the valve chamber 100 is raised through the upper surface of the shaped steel support 20, work is performed regardless of the curing of the poured concrete 40. That is, the concrete 40 may be poured into the filling space formed through the section steel support 20 and the blocking panel 30 by the height of the section steel support 20, and then the valve chamber 100 may be placed before curing.

As described above, even if the valve chamber 100 is placed through the shaped steel support 20 before the concrete 40 is cured, the concrete 40 is maintained without being deformed or damaged.

Lastly, as shown in FIG. 6 (f), after the pipe line and the valve facility are piped to the valve chamber 100, the burnished portion is backfilled. For example, the upper cover 104 assembled in the valve chamber 100 is separated, and then various valve facilities are assembled and connected to the pipeline in the housing 102, and the separated upper cover 104 is assembled again, followed by the upper cover. After the manhole 106 is installed in the 104, the filling operation of the valve chamber 100 is completed by backfilling.

As described above, when the valve chamber 100 is installed and refilled in the foundation concrete structure 10 before the concrete 40 is cured, the concrete 40 is cured in the ground and is formed in the ground. It is integrated with (20).

According to the present invention, the valve chamber 100 may be installed in the basic concrete structure 10 before the concrete 40 is cured as described above, and the valve chamber 100 may be installed in the basic concrete structure 10 after the concrete 40 is cured. Of course, you can install it.

On the other hand, according to a modification of the present invention, as described above, at least one or more auxiliary steel 70 (or 'c'-shaped channel) is fixedly installed on the bottom of the valve chamber 100 and the auxiliary steel ( 70 is embedded in the poured concrete 40, the valve chamber 100 is to be embedded in the valve chamber 100 in the form integral with the basic concrete structure (10).

The auxiliary steel 70 (or 'c' channel) can be produced together with the valve chamber 100 when manufacturing in the factory, it can be simply installed on the floor of the valve chamber 100 by welding in the field.

As described above, it becomes one body with the basic concrete structure 10 of the valve chamber 100 through the auxiliary steel 70 (or 'C' channel) to prevent the valve chamber 100 from floating as described above. You can do it.
