The present invention relates to a precast basic structure and a construction method using the same. In particular, the precast basic structure mainly focuses on a conduit support member made of a structural material that supports and distributes upper loads, and a cushion material that flexibly responds to uneven settlement of the foundation ground. It is done.

Conduit (fume pipe) and water and sewage pipes. It refers to waste water pipes and drain pipes.

The location of the conduits varies.

Particularly problematic installation locations are narrow roads where dwelling equipment and ready-mixed vehicles are impossible to enter and dwelling with frequent traffic, or access to digging equipment and ready-mixed vehicles, but traffic is difficult due to frequent traffic. . In these places, it is most important to complete the conduit installation in the shortest time.

In the case of narrow roads with dense houses, installation of the excavation equipment and ready-mixed vehicles is impossible, so installation work is inevitably dependent on manpower. In addition, when the foundation layer is formed by concrete after the trench is installed to install the conduit, there is a problem in that the installation work becomes longer due to the concrete curing period.

In addition, if the traffic is difficult to control the place where frequent traffic, there is a problem that can not be installed at all due to the curing period if the base layer is formed by concrete as in the prior art.

Thus, the base layer is made of concrete in order to solidify the base layer. This is because when the foundation layer is firm, leakage of the conduit junction is prevented against local inequality.

In general, the concrete foundation layer has an advantage that the gap is not widened in the conduit joint because the bearing capacity is large against local inequality. On the contrary, since the material of the foundation layer is concrete mortar, the curing period during which the concrete is cured is too long. This is especially true because our speed of life is much shorter than this.

In order to omit the curing period of concrete, the material of the foundation layer should be replaced with another material instead of concrete. The supporting member made of the substitute material is to be able to arrange the ground immediately after the excavation and to be installed on it immediately, and the supporting member should have a structure that is capable of distributing and supporting the upper load and at the same time having excellent adaptability to uneven settlement.

The supporting member of the present invention having such a requirement was made of a structural material that serves to support the upper load and a cushioning material that acts as a buffer against uneven settlement. These two members are precast in the factory as a single member, so they are completely independent of the curing period.

The supporting member, in which two members are integrated into one, responds to the upper load and the uneven settlement by the synergy of the supporting force and the buffering force. This synergy of support and cushioning force prevents the gap between the conduit joints while supporting the upper load and the uneven settlement on the trench foundation layer rather than the concrete layer.

In other words, the support of the upper load is in charge of the support of the upper load, which is a structural member of the conduit support member, and the flexible response to the differential settlement is to be made by the cushion material having a wide surface area in contact with the foundation ground. However, the support of the upper load does not support only the upper load and does not respond to uneven settlement at all. Since the entire lower part including the bottom support part is formed in one plate on the support of the upper load, the wide bottom support part may correspond to the uneven settlement of the foundation ground. Similarly, cushioning materials that are highly adaptable to unequal settlings do not support upper loads at all. This is true in terms of the main role.

As described above, the supporting member of the present invention is manufactured in advance in a factory, so it is suitable for a tight time construction, that is, an area where traffic control is impossible or an area where heavy equipment cannot enter.

Conventionally, after installing the trench to install the sewer pipe as shown in FIG. 1, the foundation layer 500 was formed by concrete, and a conduit 400 was installed thereon. At this time, since the socket portion 410 of the conduit 400 and the conduit 400 is larger in diameter than the body 420 of the conduit 400, the socket portions 410 to which the conduit 400 is connected are the concrete foundation layer 500. Since the body between the socket portion and the socket portion connected to the floating portion is floating from the base layer 500, the body 420 of the conduit 400 may be supported by using the holding member 100 such as stone and wood. It was made.

After the conduit was installed as described above, the conduit was buried with soil, and the upper part was paved with concrete or asphalt to complete the construction of the drainage and sewer.

In case of conduit construction of drainage and sewerage as above, the construction is delayed by the time when concrete is cured by breaking the foundation after it is expelled and the ground where water flows on the construction ground or wetland and ground where water flows. Curing of the concrete is more time-consuming, so there is a problem that the air is longer and the cost of construction increases, and in some narrow alleys of downtown, the place may be narrow and the foundation work may not be possible.

In addition, when the ground on which the conduit is installed is a soft ground, there is a need for a foundation that can securely support the conduit (fume pipe) because an uneven settlement may occur and water leakage may occur due to a spaced connection part connected to the conduit.

Unequal settlement means damage to the upper structure because the foundation ground supporting the structure is not settled evenly. Even settling does not damage the superstructure at all. This is because the upper structure sinks in the same way as the foundation ground.

If erosion occurs, the conduit installed on the top of the foundation is also affected by erosion.

The degree of settlement depends on the entire length of the conduit. Especially at the junction of the conduit is the most damaged. The result of the damage is that the junction opens and leaks into the gap, which can no longer serve as a conduit. The length of the conduit can range from several hundred meters to several kilometers. The cause of leaks at long distances in conduit joints is mostly due to uneven settlement of the foundation ground. Where there is a sudden change in the thickness of the soft layer, there is a danger of causing large inequality. In addition, the difference in the magnitude of the load applied to each foundation and the local unevenness of the foundation ground during construction also cause the settlement.

The present invention is intended to prevent leakage of the conduit junction due to unequal settlement.

The requirements of the present invention for preventing opening of the conduit joint are as follows.

① In order to distribute the upper load evenly on the foundation ground, the supporting member should have the maximum surface area that is in contact with the foundation ground.

② The supporting member should be dualized with structural member supporting upper load and cushion member cushioning uneven settlement.

For this purpose, the structural members supporting the upper loads should have a structure that distributes the load to the base layer widely. The cushioning material should have the maximum surface area in contact with the base layer in order to increase the buffering effect against the differential settlement. It is preferable to make the entire surface area of the support member except the structural member as a cushion material.

③ The supporting member should be light enough to be easily handled by human power rather than mechanical power.

If the supporting member is heavy, it is almost impossible to install conduits in narrow alleyways where heavy equipment is difficult to enter. This is especially true if there are frequent traffic.

④ The supporting member should be precast product.

The supporting member in the present invention is a member that satisfies the above requirements.

The supporting member is a precast product consisting of an upper load support and a support. The upper load support is a structural material that serves to support the upper load. Unlike the structural member, the support member is a cushion member that plays a role in preventing the subsidence of the supporting member by widening the surface area which is in contact with the foundation ground. As described above, the supporting member has a structure in which the role of the upper load supporter and the supporter are binarized differently from each other. Since the support is not a structural material, it is lighter than the upper load support. Since the support is light, the support member is easy to handle.

Therefore, the upper load support has a structure that supports and disperses the upper load widely and its material is a rigid material, while the support has a structure that buffers uneven settlement while being widely folded with the foundation, and the material is a soft material.

The present invention is a conduit by eliminating the curing period where it is impossible to enter the excavation equipment and ready-mixed vehicle and the entry of narrow roads or dwelling equipment and ready-mixed vehicles where dwellings are frequent, but the traffic is difficult to control the traffic. The purpose is to minimize the installation time of the conduit, and to prevent gaps in the conduit joints, the conduit pedestal has a different purpose to prevent uneven settlement, and the conduit pedestal is dualized by the structural material and the cushion material, so that the upper load is It is another object to support the structural member and to cushion the inequality so that the cushion member is in charge to further improve the adaptability to the inequality.

The present invention is to achieve the above object, the support member is largely composed of an upper load support that is a structural material for supporting the upper load and a support that is a cushioning material to cushion the differential settlement.

Since the upper load support is supporting the upper load, the position is to be placed at a position where the upper load of the conduit can be evenly distributed and supported. Once the position of the upper load support is determined, the support fills the rest of the conduit. The support part is a lightweight material such as EPS (Expandable Polystyrene) to form the base of the conduit, and the joint part is molded into a socket shape and the waste vinyl and fly ash (Fly-ash) The upper load support formed by mixing rigid materials is embedded to support the load of the conduit with the upper load support so that the balance can be maintained and the socket portion to which the conduit and the conduit are connected is supported by the support so that uneven settlement occurs. It is possible to maintain the watertightness of the connection part even if the conduit is installed, and also to use the conduit support member quickly and firmly regardless of the adverse conditions such as the place where the conduit is installed, where the water flows, the soft ground, and the narrow alleyway. It is intended to be installed.

 This will be described in more detail as follows.

The support part of the conduit support member is a synthetic base composed of the support part by embedding the upper load support with rigid material such as a rigid material mixed with pevinyl and flyash to reinforce the bearing capacity of the conduit support member. . The upper load support can be lightened in a grid or circle within the range of supporting the load. It is suitable for the construction requiring urgent load because the upper load support is in charge of the upper load and the unequal settlement is a precast synthetic base having the structure in charge of the support made of EPS material.

Hereinafter, an embodiment of the present invention will be described in detail.

In the conduit support member which can support the conduit used as a drain pipe, a sewer pipe, and a water channel, the insertion groove 21 which consists of foamed resin bodies (EPS), such as a styro foam, and which the conduit socket part 41 is seated on the upper surface 21 ) And the support portion 20 provided with the groove portion 22 on one side, and the other side is provided with a groove portion 31 to correspond to the shape of the conduit 40 body 42 on the upper side, the body 42 The conduit support member 10 which integrally formed the support part 30 in which the upper load support 32 was embedded in () is comprised.

The upper load support 32 has an upper portion having the same shape as the recess 31 of the support portion 30 and has a plurality of lattice protrusions 33 on the upper surface thereof, and has a lower support portion 35 so as to protrude outward from all directions. Is formed.

The upper load support 32 is the bottom support portion 35 and side wall reinforcement ribs 34 are formed on all sides are configured to distribute the load.

The lower support 35 of the upper load support 32 is formed to protrude about half the height of the body 42 of the upper load support 32.

Since the upper load support 32 is a structural member supporting the upper load, the number of the upper load supporting members 32 is not only determined according to the size of the upper load, but also arranged to facilitate sharing the upper load.

The conduit support member 10 is configured to separate the support portion 20 and the support portion 30 is configured to connect the support portion 30 when necessary.

The support part 20 and the support part 30 of the support member 10 are made of a resin foam (EPS) such as styrofoam, and the upper load support 32 embedded in the center of the support part 30 is a waste vinyl chip (poly). It is composed of a mixture of Etyrene and Fly-ash.

Referring to the construction method using a conduit support member 10 which is a precast basic structure of the present invention configured as described above is as follows.

In the conduit construction method carried out by digging the ground to bury the conduit 40 and installing the base member using concrete or sand,

Digging the ground (ground) on which the conduit 40 is installed to a predetermined depth to form a buried hole;

Selecting the bottom of the buried hole and arranging the conduit support member 10 corresponding to the length of the conduit 40 to be embedded so as to maintain horizontality;

After the conduit support member 10 is installed, the load center of the conduit 40 positioned at the upper portion of the conduit support member 10 and the socket portion 41 of the conduit 40 so as to match the upper load support 32 of the conduit support member 10. Installing a conduit 40 to connect the other end thereof;

 After the conduit 40 is installed, the conduit construction is performed by filling the soil so that the conduit supporting member 10 and the conduit 40 are embedded and then arranging the ground.

Referring to the conduit construction method using the conduit support member 10 having the upper load support 32 of the present invention as described above in detail as follows.

First step: digging to form a buried hole;

In order to install the conduit, the ground on which the conduit 40 is installed is destroyed by a conventional method.

The conduit 40 referred to in the present invention refers to a fume pipe used as a sewage pipe, a drain pipe, a water channel, or a drainage channel.

Therefore, the place for installing the conduit has already been determined by the design and construction plan. In this way, the conduit installation site formed by the construction plan is excavated to the embedment depth of the conduit with a fork lane or the like to form a buried hole.

In the present invention, the buried hole refers to a trench in the form of a pit dug to fill a conduit, and the buried depth is constructed according to the design drawing, but usually forms a buried hole to a depth of 150 cm.

 In addition, when the filling hole is completed, the bottom surface is arranged so that the conduit support member 10 can be evenly arranged along the inclined surface or the horizontal surface.

 Second step: installing the conduit support member 10;

After the buried hole is formed in the first step, the conduit support member 10 is installed as a synthetic base capable of supporting the conduit 40.

At this time, in order to install the conduit support member 10, according to the length of the conduit support member 40 is installed, one of the upper load support 32 to the support portion 30 of the conduit support member 10 so as to easily share the upper load. Place more.

That is, when the length of the conduit 40 is short, one upper load support 32 is used for the support 30 of the conduit support member 10, and when the conduit is long, the support 30 is 2 It is used to install two upper load support (32).

Of course, it may vary slightly depending on the construction site, in the case of high sinking concern or soft ground, it is preferable to use that the two upper load support 32 is installed in the support portion 30 of the conduit support member 10.

In addition, the conduit support member 10 of the present invention may be used to produce a support portion 20 and the support portion 30 in close contact with each other at the construction site.

When the conduit support member 10 is divided into the support portion 20 and the support portion 30 as described above, when using a long one according to the construction site, the support portion 20 is installed in the socket portion 41 to which the conduit is connected. It can be used by placing the supporting member on the bottom that is the center of the body of the conduit. In addition, when using one or more support members 10, the support portion 20 is installed on one side of the support portion 30, the other can be installed continuously on one side of the support portion 30 is installed.

In this case, by using the support part 30 freely according to the construction site or the length of the conduit, the upper load support 32 formed on the support part 30 primarily supports the upper load, and the support part 20 is supported. And the support 30 is to be able to support the load of the conduit secondary.

Third step: conduit installation step;

After the conduit support member 10 is installed in the second process, the socket portion 41 of the conduit is installed so as to be positioned in the insertion groove 21 of the support portion 20 installed on the basis.

At this time, the groove portion 22 of the support portion 20 can support the body of the conduit like the groove portion 31 of the support portion 30.

Insertion groove 21 of the support portion 20 is formed so that the insertion groove is formed so as to correspond to the socket shape of the conduit to protect the connection of the conduit and the conduit, even if some uneven settlement occurs the support portion 20 is lightweight It is made of styrofoam material to prevent the connecting portion of the conduit from being spaced apart by the buffering action.

In addition, the upper load support 32 is formed to be embedded in the central portion of the support portion 30 is made of a stiff material mixed with waste vinyl and fly ash to support the load of the conduit and the vertical load by the lower support portion 35 Distributes

In addition, the upper surface of the upper load support 32 is formed in the same shape as the groove portion 31 of the support portion 30, the surface is exposed state and the surface portion is formed lattice projection 33 to support the conduit located on the upper portion It is possible to do and transfer the load of the conduit to the upper load support 32 and at the same time serves to distribute / support with the lower support (35).

Therefore, the conduit support member 10 composed of the support portion 20 and the support portion 30 is used as a basic precast when installing the conduit, and serves to protect the entire load and protect it from uneven settlement.

4th step: soil filling finishing step;

 After the conduit is installed, the conduit supporting member 10 and the conduit are filled with soil to fill the conduit and fill the buried hole.

In the process of filling the buried hole around the conduit and the conduit support member 10 is filled with soil generated when digging without covering rubble stones, and compacted and arranged the upper surface of the ground and the conduit installation construction is completed.

As can be seen from the above construction method, the present invention has the advantage that the construction work is easy and the air is shortened by using the conduit support member 10 which precast the synthetic base regardless of the construction site environment.

Brief description of the accompanying drawings of the present invention as follows.

Figure 2 is a perspective view of the conduit support member according to the present invention, the conduit support member 10 is made of a support portion 20 and the support portion 30 integrally, the support portion 20 is a socket portion 41 which is a connection portion of the conduit Insertion groove 21 is formed so that can be seated, the one side support portion 30 is the upper load support 32 is installed to support the load of the conduit.

The upper load support 32 is made of a stiff material mixed with waste vinyl and fly ash, and the remaining part of the support and the support part are made of lightweight styrofoam material such as EPS to cushion the secondary load of the conduit 40 together with the buffering action. I could support it.

The support part 20 and the support part 30 form grooves 22 and 31 having a semi-groove shape so that the body 42 of the conduit 40 can be seated in the longitudinal direction, and the support part on which the socket part of the conduit is seated.

The lattice-like protrusions formed on the upper surface of the upper support 32 are not necessarily formed at the time of manufacture and may not form the lattice protrusions as necessary.

The support portion 30 having the upper load support 32 may be formed to correspond to the length of the conduit 40 or may be formed shorter than the length of the conduit 40, but is installed in the support 30 The upper load support 32 is located in the center of the conduit 40 to support the upper load, the support portion 20 is placed on the foundation ground while wrapping the connection between the conduit and the conduit to evenly distribute the load of the conduit 40 have. In particular, the role of the support 20 serves to prevent the unequal settlement of the conduit 40 while widely distributing the upper load of the conduit 40 on the foundation ground.

 As described above, the upper load support 32 is made of steel by mixing waste vinyl chips (poly-etyrene) and fly ash (Fly-ash) to firmly support the conduit.

In addition, the conduit receiving member 10 of the present invention can be precast into a forming mold having a certain shape.
