Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy construction, in particular to a riverside thorn wall structure. Background Art

[0002] During the water conservancy construction process, water seepage in the foundation pit may occur.

[0003] The prior art discloses a construction method for a hydraulic underground seepage cut-off wall, including: trenching: digging a trench underground where groundwater needs to be intercepted, the trench width is designed to be 1 meter, and the length is determined according to the trench width, and using an excavator to dig the sand and soil below the stratum into a trench shape; and pouring the seepage cut-off wall: using a template to make a waterproof cement concrete mold in the middle of the trench, the mold width is 0.6 meters, the mold cavity is lined with a steel skeleton, and waterproof cement concrete is poured into the mold. After the waterproof cement concrete is solidified, the mold is removed to form a waterproof cement concrete wall, and then an asphalt concrete outer layer is poured between the outer side of the waterproof cement concrete wall and the two walls of the trench, and the asphalt concrete outer layer and the waterproof cement concrete wall form a seepage cut-off wall.

[0004] However, when constructing in an area close to a river, there is abundant groundwater near the river. Since the bottom of the foundation trench is made of stone and has strong water permeability, it is difficult to drain the water in the foundation trench. In the process of building a thorn wall, the concrete pouring of the related technology to form a cut-off wall is difficult and cannot meet the requirement of a dry construction environment when pouring concrete for the thorn wall. The installation of formwork, removal of formwork and multiple pouring in the related technology will increase costs and prolong the construction period. Utility Model Content

[0032] As attached Figure 1 and Figure 2 As shown, in an exemplary embodiment of the riverside thorn wall structure of the utility model, the riverside thorn wall structure includes:

[0033] The foundation trench is located 100-150 meters away from the river channel, perpendicular to the direction of the river. When the foundation trench is excavated to the bottom, it is all stone and there is groundwater in the foundation trench.

[0034] The mounting piece is a cube with an open top and a hollow interior. Multiple mounting pieces are arranged in the base trench parallel to the direction of the river.

[0035] A waterproof layer covers the outer surface of the installation member.

[0036] A concrete layer is formed by pouring concrete into the installation member through the top opening of the installation member to form a thorn wall structure.

[0037] In the above-mentioned schematic embodiment, the problem of not being able to provide a dry environment for concrete construction during the construction process is solved. A dry environment for concrete setting can be provided during construction, thereby reducing costs and shortening the construction period.

[0038] The waterproof layer includes an HDPE geomembrane.

[0039] In some embodiments, a support crossbar is provided at the top of the installation member.

[0040] A plurality of support crossbars are fixed to the top of the installation member, which can improve the stability of the installation member.

[0041] In some of these embodiments, it further includes:

[0042] A counterweight is used to change the weight of the installation member so that the installation member reaches a preset position in the water of the foundation trench.

[0043] The counterweight changes the weight of the installation member, causing the installation member to sink in the water of the foundation trench until it reaches the preset position.

[0044] In some of these embodiments, it further includes:

[0045] Fixing members are located between the installation member and the foundation trench. A plurality of fixing members are spaced at a preset distance and fix the installation member in the foundation trench after the installation member reaches the preset position.

[0046] The fixing members include 7-shaped steel bars.

[0047] The fixing members are used to fix the installation member and reduce the shaking and displacement of the installation member.

[0048] In some of these embodiments, the height range of the installation member is 1.0 m - 1.5 m, and the length is 2.0 m - 8.0 m.

[0049] The size of the installation member is adapted to the foundation trench and can be placed inside the foundation trench.

[0050] The following combines the attached Figures 1 - 2 Describe the specific structure and working process of an embodiment of the river-facing thorn wall structure of the present utility model:

[0051] First, the foundation trench is excavated in the area 100 meters to 150 meters away from the river channel to a depth of 1.2 meters. There is less soil and more round stones at the bottom of the foundation trench at this depth. The geology at the bottom of the foundation trench is good at this time, without deep sinking, settlement, or loosening, and has high bearing capacity. A drainage ditch is set up during the excavation process for pumping water with a water pump. Due to the proximity to the water source and the fact that the bottom of the foundation trench is made of stones with strong water permeability, the water inside the foundation trench cannot be completely emptied.

[0052] Secondly, the installation part is fabricated to form a cube with an open top and a hollow interior, and the top is reinforced with support crossbars. A waterproof membrane is covered on the outer surface of the installation part to form a waterproof layer.

[0053] After that, the installation part covered with the waterproof layer is placed into the foundation trench. Counterweights are added to the installation part to increase its weight, causing it to sink in the water of the foundation trench until the installation part reaches the preset position. The distance between multiple fixing parts is 0.5 m, and they are inserted into the soil layers on both sides of the installation part with an insertion depth of 40 cm. The installation part is fixed in the foundation trench.

[0054] Finally, the counterweights are removed from the installation part, and concrete is poured from the open top of the installation part to form a spur wall structure.

[0055] Through the description of multiple embodiments of the spur wall structure near the river of the present utility model, it can be seen that the embodiments of the spur wall structure near the river of the present utility model have at least one or more of the following advantages:

[0056] 1. The installation part and the waterproof layer provide a dry environment for concrete pouring, enabling the spur wall construction to be completed faster and shortening the construction period.

[0057] 2. For the formation of a spur wall, only one installation of the installation part and one concrete pouring are required, reducing the construction cost.

[0058] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0059] The above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them; although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still, the specific implementation manners of the present utility model can be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present utility model, they should all be covered within the scope of the technical solutions claimed by the present utility model.
