The unloading conversion plate type retaining wall comprises a foundation, a wall panel is vertically arranged at the top of the foundation, and an unloading conversion plate is arranged on the rear side of the wall panel; and the unloading conversion plate is obliquely arranged downwards and is arranged in the soil body of the fill slope. Compared with the prior art, the device has the advantages that the unloading conversion plate structure is used for converting the soil pressure direction, so that a soil body on the unloading conversion plate tends to move inwards, and reverse downward sliding force acts on the plate. The original on-board soil body unfavorable for retaining wall stability is changed into one part of the retaining wall, and the on-board soil body and the retaining wall jointly resist natural stable soil body of soil pressure. The supporting and retaining structure is clear in soil pressure stress mechanism, simple in theoretical calculation, simple in supporting and retaining structure construction, convenient in material taking, convenient to transport and install, low in manufacturing cost, suitable for small working faces, short in construction period, and suitable for working conditions such as poor soil texture conditions; the lateral displacement of the foundation pit and the side slope is reduced, the stability is improved, and the method is subversive innovation for traditional foundation pit and side slope design and calculation theories.

The present invention relates to the fields of water conservancy engineering and shipping engineering, and discloses a ship lift tower column structure with a sparse pile raft foundation and a layered strong constraint box beam, comprising a tower column body, the tower column body comprising two tower column groups that are symmetrical on both sides, the space between the two tower column groups forming a ship compartment, a raft foundation being arranged directly below the tower column body, a sparse pile group being arranged directly below the raft foundation, a plurality of layers of connecting box beam groups being arranged between the middle and upper parts of the two tower column groups, each layer of connecting box beam groups comprising two connecting box beams located at the most upstream and the most downstream, a top beam group comprising a plurality of top beams being arranged between the tops of the two tower column groups, and the two ends of the top beams being fixedly connected to the two tower column groups. The present invention provides a ship lift tower column structure with a sparse pile raft foundation and a layered strong constraint box beam, effectively controlling the uneven settlement of the ship lift foundation and its later rheology, reducing the lateral deformation of the structure, avoiding the torsional deformation of the tower column, and reducing the stress of each key part of the ship lift structure.

The invention relates to a fiber grid reinforced cast-in-place reinforced concrete shear wall and a construction process. The fiber grid reinforced cast-in-place reinforced concrete shear wall comprises concrete, horizontally-distributed steel bars and vertically-distributed steel bars, and fiber grid cloth is poured on the left side and the right side of the concrete. The threaded rods with the iron plate nuts are connected to the intersection points of the horizontally-distributed steel bars and the vertically-distributed steel bars, and the connecting pieces distributed in the shape like the Chinese character'jing 'are arranged on the outer surfaces of the iron plate nuts, so that before concrete is poured, the fiber gridding cloth is fixed to the preset position, and it is guaranteed that in the concrete pouring and vibrating process, the fiber gridding cloth is not prone to falling off. And the position of the fiber gridding cloth is not changed, and finally the fiber gridding cloth and the reinforced concrete wall form a whole to jointly resist external loads. Besides, the screws with the iron plate nuts can work cooperatively with the high-strength screws penetrating through the formworks, it can be guaranteed that the distance between the formworks on the two sides of the shear wall body and the distance between the formworks and the outer surfaces of steel bars meet the design requirement, and it can be guaranteed that formwork expansion does not occur during concrete pouring and vibrating.

The utility model belongs to the field of automobile parts manufacturing technology, specifically, the utility model relates to a kind of reinforcing structure of automobile A column and B column;A kind of reinforcing structure of automobile A column and B column, including reinforcing shell, the reinforcing shell is arranged in A column and B column, reinforcing structure is arranged in the reinforcing shell;First reinforcing plate strengthens the intensity of A column and B column in longitudinal direction, effectively resist longitudinal tensile and compression force, prevent column body to occur longitudinal bending or fracture when colliding;Second reinforcing plate of interval distribution then strengthens horizontal rigidity, so that A column and B column can better keep structural integrity when being subjected to lateral impact, reduce lateral deformation. Both synergies, significantly improve the safety of A column and B column under complex collision working condition.

The utility model discloses a kind of special-shaped stations of continuous hole of side wall, including station roof, station middle plate, station bottom plate, station underground first layer special-shaped column, station underground second layer middle column and station side wall, station roof is composed of flat plate and inclined plate, inclined plate one side is connected with flat plate, and other side is inclined downward;Station underground first layer special-shaped column is wavy, the connecting place of station underground first layer special-shaped column crest end is connected with flat plate and inclined plate, trough end is connected with station middle plate top;The first layer of special-shaped station is connected with sunken square through door hole, and multiple door holes are provided along longitudinal direction;Station side wall is divided into non-sunken square side thickened side wall set away from sunken square and sunken square side side wall close to sunken square, and the outside of non-sunken square side thickened side wall is provided with non-sunken square side T-shaped underground wall.The utility model has the advantages that: station roof uses inclined plate to lift net height, so that station net height is lifted, and station spaciousness is increased.

An inflatable neck pillow includes a pillowcase, a pillow core, and an adjusting member. The pillowcase includes an inner cavity for accommodating the pillow core, which supports the user's neck. The pillow core has a wearing channel for the user's neck, and the adjusting member is disposed along the wearing channel. When the user uses the inflatable neck pillow, adjusting the adjusting member can change the size of the wearing channel. The pillow core includes a support member and an air bladder, both of which have elastic properties. The support member conforms to the user's neck to support it, and a receiving groove is provided on the outer side of the support member. Part of the air bladder is placed in the receiving groove to support the support member, and the air bladder protrudes from the receiving groove. The air bladder of this neck pillow has an auxiliary effect on the support performance of the neck pillow, increasing user comfort and the flexible support performance of the neck pillow. After deflating the air bladder, it is also convenient to store and carry. Adjusting the adjusting member can change the size of the wearing channel so that the user can adjust the wearing channel to meet their needs, making the neck pillow highly adjustable.
