The invention discloses a grouting bag type end-enlarged anchor rod for tunnel rectification and a use method. A sealing cover and the bottom of an outer tube define a gap into an annular inner cavity, and a plurality of separation pieces for separating the annular inner cavity into a plurality of separate chambers in a sealing manner are arranged in the annular inner cavity at intervals; an outergrouting hole is formed in the wall of the outer tube in each separate chamber, an elastic grouting bag is fixed arranged outside each outer grouting hole in a covering manner, and inner cavities ofthe elastic grouting bags are in sealed communication with the corresponding separate chambers through the corresponding outer grouting holes; an inner grouting hole for communicating the annular inner cavity with an inner tube is formed in the wall of the inner tube, and an opening for realizing grouting in the inner tube is formed in the top end of the inner tube; the inner tube and the inner grouting hole are communicated to form a first channel for performing grouting on the separate chambers one by one; the outer grouting hole in each separate chamber is communicated with the corresponding elastic grouting bag to perform grouting on the corresponding elastic grouting bag.

The invention relates to the technical field of civil engineering, and discloses a foundation pit slope protection reinforcement device for civil engineering, including a base plate, a support column is fixedly installed at the top center of the base plate, and a motor is fixedly installed inside the support column , one side of the support column is provided with a parts installation cavity, and a first threaded column is movably installed in the parts installation cavity. The present invention drives the first threaded column to rotate through the rotation of the motor inside the support column, and the first threaded column rotates When the first threaded block moves, it will drive the first connecting column to change the angle between it and the supporting column, so that the first connecting column will rotate through the pin block and the sliding block when it moves The block moves, and when the rotating block rotates, it will rotate around the first fixed column until the rotating block can be connected with the limit ring block, so that the first fixed plate and the second fixed plate can reinforce the slope protection.

The invention discloses a displacement self-restraint type prestressed FRP sheet tensioning device and an implementation method thereof. The tensioning device comprises a steering part (2), a fixed part (3), a tensioning part (5) and a tensioning and supporting part (6); and one end of an FRP sheet (4) is fixed to one end of the tensioning part (5), and the other end of the FRP sheet (4) is fixedto the other end of the tensioning part (5) through the steering part (2), the fixed part (3), the tensioning and supporting part (6), the fixed part (3) and the steering part (2). The implementationmethod comprises the steps that the position and length of the FRP sheet (4) are determined according to actual demand, then the steering part (2), the fixed part (3), the tensioning and supporting part (6) and the tensioning part (5) are fixed, and finally, the FRP sheet (4) is tensioned through the tensioning part (5). The implementation method has simple operation and low construction cost, efficiently uses the FRP material performance, and improves the performance of a reinforced object.

The invention discloses a construction method for reinforcing wooden purlins with hoop racks, which comprises the following steps: step 1: cleaning and trimming the parts of the wooden purlins to be reinforced; step 2: using at least two cable ties to fix the upper teeth The purlins, middle racks, and lower racks are respectively fixed on the upper, middle, and lower parts of the wooden purlins cleaned and trimmed in step 1. After adjusting and aligning each rack, knock each rack into the purlin bar with a hammer; step 3 : Set at least two clips on the sandalwood strips processed in step 2. The invention achieves the purpose of increasing the bearing capacity by adding stainless steel racks and clamps to the wooden purlins, and is suitable for the reinforcement of wooden beams, wooden purlins, wooden beams, wooden rafters and other components in ancient wooden frame buildings. A clamp disclosed by the invention The construction method of rack-reinforced wooden purlins has little interference with the original shape of the components, which neither affects its authenticity, but also has reversibility, which can meet the principles of cultural relics and architectural protection.

The invention discloses a soft soil area underground continuous wall leakage detecting system, solves such defects as complex construction, difficult measurement and lower accuracy of measured results, and measures specific positions of leakage points more accurately. The transport process of underground ions and the gathering process of the underground ions are observed in real time, so that the specific positions of the leakage points can be obtained more quickly and accurately. The soft soil area underground continuous wall leakage detecting system relates to a underground continuous wall, an observation well, a precipitation well, a soft soil layer, an aluminum electrode, an electrifying device, an electrifying device positive pole, an electrifying device negative pole, an in-pit ground, an out-pit ground, the leakage points, aluminum ions, a sampling device, a slide cover, a bracket, an opening cylinder, a gauze, a separation plate, a round hole, a sensor, a circuit, a circuit fixator, a circuit negative pole and an acquiring system. The underground continuous wall is not limited by thickness and depth. The observation well is used for observing change of an underground water level on the outer side of a foundation pit; the gap and the depth of the observation well are determined according to actual engineering; and the observation well also can serve as a foundation pit outer side precipitation well. The precipitation well is a foundation pit inner side precipitation well, and can be used for observing a underground water level on the inner side of the foundation pit. The soft soil layer is a soil layer suitable for an electroosmosis method.
