Description

管冪地下道防水膜及鋼筋定位結構Waterproof Membrane and Rebar Positioning Structure of Guanmi Underpass

本發明係有關一種管冪地下道防水膜及鋼筋定位結構，尤指一種施工更為方便、更具效率、節省成本、縮短工期，且可防止於施工時造成防水膜之地下道防水膜及鋼筋定位結構。The invention relates to a waterproof membrane and a steel bar positioning structure for a pipe power underground passage, especially a construction that is more convenient, more efficient, saves cost, shortens the construction period, and can prevent the waterproof membrane and the steel bar positioning structure of the underground passage from causing the waterproof membrane during construction. .

按；地下道挖掘管冪工法主要將鋼管利用反力設備逐支水平向鑽掘後推入土層內，形成口字型（或ㄇ型）之鋼管圍幕以抵抗周圍土壓，以保護涵洞開挖時四周土體穩定及止水房掏空功能，再配合臨時支撐進行分階段開挖。臨時支撐係在開挖時每隔適當距離設置水平及垂直之H型鋼支撐，以抵擋在開挖時的上層土壓側向土壓及底版土壤解壓***所造成的上方路基或土層下陷崩塌情形。Press; the pipe power method of underground tunnel excavation mainly pushes the steel pipes into the soil layer after drilling horizontally one by one using the reaction force equipment, forming a mouth-shaped (or ㄇ-shaped) steel pipe enclosure to resist the surrounding earth pressure and protect the culvert opening. During the excavation, the surrounding soil is stable and the water stop room is hollowed out, and then the excavation is carried out in stages with temporary support. The temporary support system is to set horizontal and vertical H-beam supports at appropriate distances during excavation to resist the subsidence and collapse of the upper subgrade or soil layer caused by the lateral soil pressure of the upper layer and the decompression and uplift of the bottom plate during the excavation. .

習知之管冪工法於施工時，如圖1所示，係將複數之管冪鋼管１相互連結形成口型之管冪鋼管１圍幕，管冪鋼管１內緣係設有H型鋼２，以先進行噴漿與H型鋼齊平後再鋪設防水膜再配合後續鋼筋綁紮板模之設置及灌漿作業。而為能達到防水目的，習知之施工方式，係於前述之H型鋼２噴漿再貼上防水膜３，此種結構除了耗工費時效率不彰增加噴漿工時及費用，且噴漿會掉料、造成材料浪費外，且防水膜３難以轉折（H型鋼２的縱、橫向交接處難以施工）。再者；當鋼筋於組裝過程中，無論於綁鐵絲或焊接鐵絲的作業，因防水膜與鋼筋太接近，在鋼筋搬動皆容易導致防水膜３的被戳破或氧氣乙炔切割鋼筋時的熱度熔毀防水膜，間接影響防水效果。申請人有鑑於此，經不斷研究、實驗，遂萌生設計一種地下道防水膜及鋼筋定位結構，使防水膜的施工不會受到H型鋼支撐的阻擋更為方便、更具效率，且可防止於後續施工時造成防水膜的損壞，並能節省鉅額噴漿費用及工時有效縮短工期。During the construction of the conventional pipe power construction method, as shown in Figure 1, a plurality of pipe power pipes 1 are connected to each other to form a curtain of a mouth-shaped pipe power pipe 1, and the inner edge of the pipe power pipe 1 is provided with H-beam 2, so as to form a curtain wall. First, the shotcrete is flush with the H-beam, and then the waterproof membrane is laid, and then the setting and grouting of the subsequent steel bar binding formwork are carried out. In order to achieve the purpose of waterproofing, the conventional construction method is based on the above-mentioned H-beam 2 shotcrete and then pasted with a waterproof membrane 3. This kind of structure is not only labor-intensive, time-consuming, and inefficient, but also increases the time and cost of shotcrete. In addition to material loss and material waste, the waterproof membrane 3 is difficult to turn (the vertical and horizontal junctions of the H-beam 2 are difficult to construct). Furthermore, when the rebar is being assembled, no matter in the operation of tying iron wire or welding iron wire, because the waterproof membrane is too close to the rebar, it is easy to cause the waterproof membrane 3 to be punctured or the heat when the oxygen acetylene cuts the rebar when the rebar is moved. Melt down the waterproof membrane and indirectly affect the waterproof effect. In view of this, the applicant, after continuous research and experimentation, came up with the idea of designing an underground tunnel waterproofing membrane and a steel bar positioning structure, so that the construction of the waterproofing membrane will not be blocked by the H-beam support, which is more convenient and efficient, and can prevent the subsequent construction of the waterproof membrane. It will cause damage to the waterproof membrane during construction, and can save a huge amount of shotcrete costs and man-hours and effectively shorten the construction period.

本發明之主要目的，即在提供一種管冪地下道防水膜及鋼筋定位結構，於管冪工法之地下道挖掘作業時，使防水膜的鋪設施工更為方便、更具效率，且可防止於後續之鋼筋施工時，造成防水膜的損壞。The main purpose of the present invention is to provide a waterproof membrane and a reinforcing bar positioning structure for a tunnel underpass, which can make the laying of the waterproof membrane more convenient and efficient during the tunnel excavation operation of the tunnel construction method, and can prevent subsequent Damage to the waterproof membrane during the construction of the steel bar.

For the purpose of construction, hang the waterproof membrane on the top holding parts of these support rods, so that the waterproof membrane can be hung under the tube power steel pipe along the arc surface of the tube power tube, so that the waterproof membrane can be freely attached to the tube power tube. The surface of the waterproof membrane is overlapped on the surface of the pipe power steel pipe, which can really reduce wrinkles, make the construction of the waterproof membrane easier and more convenient, and the lap joint effect is more optimized. H-beam welding hooks are used to fix the position and height of the top steel bars, and can support the weight of the top steel bars to achieve smoothness and safety.
