Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, and particularly relates to an edge sealing structure for construction of an underground concrete wall. BACKGROUND

[0002] A large number of airtight walls need to be constructed in a coal mine, especially in each roadway connected with a goaf, and a fireproof airtight wall needs to be constructed. The airtight wall needs to be tight and not leak air, and needs to bear a large mine pressure. The concrete airtight wall is a relatively ideal airtight wall. Before the concrete airtight wall is constructed, a concrete formwork needs to be erected, and then concrete paste is poured into the formwork. The aluminum alloy formwork is repeatedly used many times, is quickly installed, has low cost, is energy-saving and environment-friendly, and has been widely used in ground building construction projects. The cross section of the underground roadway is generally rectangular, which can meet the installation conditions of the aluminum alloy formwork. However, when the aluminum alloy formwork is applied to the construction of the concrete wall in the coal mine, many problems are faced, which are as follows: (1) it is difficult to tightly seal the edges of the aluminum alloy formwork and the roadway sides and roof. In the construction of the underground concrete wall, the aluminum alloy formwork needs to be tightly connected with the roadway sides and roof, so that the problem of concrete paste running can be avoided when the concrete paste is poured. Since the width and height of the roadway have certain fluctuations, and each aluminum alloy formwork usually has a fixed size, after a plurality of aluminum alloy formworks are spliced, it is difficult to make the size of the aluminum alloy formwork completely consistent with the size of the cross section of the roadway, so that a gap is formed between the aluminum alloy formwork and the roadway sides and roof, and the gap between the aluminum alloy formwork and the roadway sides and roof needs to be effectively sealed. (2) it is difficult to fix the aluminum alloy formwork close to the roadway sides and roof, and the aluminum alloy formwork close to the roadway sides and roof is easily expanded or run out when the concrete paste is poured. In order to ensure the detachability of the aluminum alloy formwork, the aluminum alloy formwork close to the roadway sides and roof is in a suspended state, so that the aluminum alloy formwork close to the roadway sides and roof is expanded or run out when subjected to the lateral pressure of the concrete paste. (3) the underground airtight wall needs to be plastered with a skirt, that is, the airtight wall and the roadway sides and roof and the surrounding rock at the contact position usually need to be plastered with a skirt with a width of not less than 100 mm and a thickness of 10 mm. In the prior art, the work of plastering the skirt is usually performed by manually plastering mortar. Since the surrounding rock and the mortar have different properties, the mortar is difficult to adhere to the surrounding rock in the construction process, so that the work of plastering the skirt is difficult and the work efficiency is low.

This avoids the problems of slow construction speed and cumbersome construction procedures that occur when using wooden boards for assembly. A rib is set on the side of the edge sealing template closest to the tunnel roof, and the straight edge of the rubber flexible sheet is embedded between the rib and the edge sealing template. Connectors are used to tightly fix the three together, ensuring a reliable seal between the rib, the rubber flexible sheet, and the edge sealing template. One end of the rubber sheet is fitted with a rolled edge, and a steel wire rope is inserted into the cavity of the rolled edge. The rolled edge is then fitted snugly to the tunnel roof. This design allows the rubber sheet to adapt to variations in the tunnel roof's shape due to its flexibility, while the steel wire rope, with its strength and elasticity, further addresses unevenness in the roof, effectively solving the problem of grout leakage at the joints. By sequentially forming a straight extension section and an arc-shaped transition section between the straight edge and the rolled edge of the rubber sheet, a skirt-like support space is created between the ribs, the rubber sheet, and the tunnel roof. When concrete is poured and solidifies, the skirt structure is directly formed within this support space during pouring, eliminating the need for manual skirting and significantly reducing the workload of workers, thus greatly improving construction efficiency. By using a back brace to abut against the edge sealing formwork and wall formwork, and then horizontally setting a square timber support column one on the outer side of the back brace and the straight extension section, with the adjacent two sides of the square timber support column one abutting against the back brace and the straight extension section respectively, the positioning and support of the edge sealing formwork, wall formwork and straight extension section can be effectively achieved. In this way, the edge sealing formwork, wall formwork and rubber flexible sheet can resist the lateral pressure of the internal concrete slurry, thereby avoiding the problems of bulging or displacement of the edge sealing formwork and rubber flexible sheet. A second square timber support column is horizontally supported on the outer side of the arc transition section, and the side of the second square timber support column is used to press the rolled edge of the rubber flexible sheet and the wire rope tightly against the tunnel roof. This effectively fixes the rolled edge of the rubber flexible sheet used for edge sealing, thus enabling the rolled edge of the rubber flexible sheet and the wire rope to resist the lateral pressure of the internal concrete slurry, thereby avoiding the problems of bulging or displacement of the formwork at the tunnel roof.

[0034] This edge-sealing structure is simple and low in implementation cost. It connects the edge-sealing template in the structure with the wall template and makes the rubber soft board in the edge-sealing structure closely adhere to the tunnel roof to form a skirt bearing space. This enables the edge-sealing operation between the template and the tunnel roof. Using this edge-sealing structure can perfectly solve the problems of difficult edge-sealing of traditional templates and easy leakage of grout at the connection. At the same time, its construction process is quick and simple. The skirt structure can be obtained simultaneously with a single pour, saving a lot of labor and significantly improving work efficiency. Attached Figure Description

[0070] The use method is as follows: in the process of constructing the closed wall, when the wall formwork 1 arranged cannot be tightly connected with the roadway roof 11, and a skirt structure needs to be formed near the roadway roof 11, the edge formwork 2 is arranged near the roadway roof 11, and the end edge of the edge formwork 2 away from the roadway roof 11 is tightly connected with the end edge of the wall formwork 1 near the roadway roof 11, then the rib plate 3 is arranged between the edge formwork 2 and the roadway roof 11, wherein the rib plate 3 is arranged horizontally; the steel wire rope 5 is inserted into the inner cavity of the curled edge of the rubber soft plate 4, then the straight edge of the rubber soft plate 4 is embedded into the gap between the edge formwork 2 and the rib plate 3, and the rubber soft plate 4 is tightly connected with the edge formwork 2 and the rib plate 3 through the connecting piece, at the same time, the curled edge of the rubber soft plate 4 is connected with the roadway roof 11, and the straight edge and the curled edge of the rubber soft plate 4 form the straight extension section 12 and the arc transition section 13; the back bead 14 is vertically arranged outside the edge formwork 2 and the straight extension section 12, the square wood supporting column one 7 is horizontally arranged outside the back bead 14 and the straight extension section 12, and the left and right ends of the square wood supporting column one 7 are respectively abutted with the two roadway sides 6, the adjacent two sides of the square wood supporting column one 7 are tightly abutted with the back bead 14 and the straight extension section 12, so that the positioning of the wall formwork 1, the edge formwork 2 and the straight extension section 12 is effectively realized, and the pressure of the inner mortar is effectively resisted, at the same time, the square wood column one is arranged at the bottom of the square wood supporting column one 7, so as to effectively support the square wood supporting column one 7; the square wood supporting column two 8 is horizontally arranged outside the arc transition section 13, and the side of the square wood supporting column two 8 near the roadway roof 11 is tightly abutted on the curled edge of the rubber soft plate 4, so as to tightly fix the steel wire rope 5 on the roadway roof 11, at the same time, the square wood column two is arranged at the bottom of the square wood supporting column two 8, so as to effectively support the square wood supporting column two 8; at this time, the skirt bearing space 9 is formed between the rib plate 3, the rubber soft plate 4 and the roadway side 6. The mortar is poured in the internal space of the arranged formwork, and the mortar forms the closed wall and the skirt structure in the skirt bearing space 9 after the mortar solidifies.

[0071] In this invention, by making the width of the edge sealing template smaller than that of the traditional standard wall template, a narrower edge sealing template can be used to replace the traditional standard wall template when the gap between the already arranged traditional standard wall template and the tunnel roof cannot meet the arrangement requirements. This avoids the problems of slow construction speed and cumbersome construction procedures that occur when using wooden boards for assembly. A rib is set on the side of the edge sealing template closest to the tunnel roof, and the straight edge of the rubber flexible sheet is embedded between the rib and the edge sealing template. Connectors are used to tightly fix the three together, ensuring a reliable seal between the rib, the rubber flexible sheet, and the edge sealing template. One end of the rubber sheet is fitted with a rolled edge, and a steel wire rope is inserted into the cavity of the rolled edge. The rolled edge is then fitted snugly to the tunnel roof. This design allows the rubber sheet to adapt to variations in the tunnel roof's shape due to its flexibility, while the steel wire rope, with its strength and elasticity, further addresses unevenness in the roof, effectively solving the problem of grout leakage at the joints. By sequentially forming a straight extension section and an arc-shaped transition section between the straight edge and the rolled edge of the rubber sheet, a skirt-like support space is created between the ribs, the rubber sheet, and the tunnel roof. When concrete is poured and solidifies, the skirt structure is directly formed within this support space during pouring, eliminating the need for manual skirting and significantly reducing the workload of workers, thus greatly improving construction efficiency. By using a back brace to abut against the edge sealing formwork and wall formwork, and then horizontally setting a square timber support column one on the outer side of the back brace and the straight extension section, with the adjacent two sides of the square timber support column one abutting against the back brace and the straight extension section respectively, the positioning and support of the edge sealing formwork, wall formwork and straight extension section can be effectively achieved. In this way, the edge sealing formwork, wall formwork and rubber flexible sheet can resist the lateral pressure of the internal concrete slurry, thereby avoiding the problems of bulging or displacement of the edge sealing formwork and rubber flexible sheet. A second square timber support column is horizontally supported on the outer side of the arc transition section, and the side of the second square timber support column is used to press the rolled edge of the rubber flexible sheet and the wire rope tightly against the tunnel roof. This effectively fixes the rolled edge of the rubber flexible sheet used for edge sealing, thus enabling the rolled edge of the rubber flexible sheet and the wire rope to resist the lateral pressure of the internal concrete slurry, thereby avoiding the problems of bulging or displacement of the formwork at the tunnel roof.

[0072] This edge-sealing structure is simple and low in implementation cost. It connects the edge-sealing template in the structure with the wall template and makes the rubber soft board in the edge-sealing structure closely adhere to the tunnel roof to form a skirt bearing space. This enables the edge-sealing operation between the template and the tunnel roof. Using this edge-sealing structure can perfectly solve the problems of difficult edge-sealing of traditional templates and easy leakage of grout at the connection. At the same time, its construction process is quick and simple. The skirt structure can be obtained simultaneously with a single pour, saving a lot of labor and significantly improving work efficiency.
