The invention discloses a building cart for civil engineering, and belongs to the technical field of civil engineering. The building cart comprises a cart body, a driving shaft is arranged between twohinge plates in an inserted mode, two ends of the driving shaft extend to the outer sides of the hinge plates and are rotatably connected with walking wheels, a one-way bearing is arranged on the middle of the driving shaft between the two hinge plates in a sleeving mode, a gear disc is welded on an outer ring of the one-way bearing, an L-shaped extrusion cylinder is welded at the bottom of the cart body on the outer side of the driving shaft, a piston plate is slidably connected with the inside of the other end of the L-shaped extrusion cylinder, a clamping strip is welded on the middle of the outer side of the piston plate, the top of one side of the L-shaped extrusion cylinder is connected with a guiding pipe, and an extrusion cylinder is transversely welded at the bottom of one cart handle. The cart can conveniently walk uphill, the labor intensity of workers is reduced, the cart body is more effort-saving in the process of going uphill, and the cart can be conveniently decelerated in the process of going downhill.

本发明公开了一种土木工程用的建筑推车，属于土木工程技术领域，包括推车本体，两个所述铰接板之间穿插有驱动轴，所述驱动轴的两端皆延伸至铰接板的外侧并转动连接有行走轮，两个所述铰接板之间的驱动轴中间位置处套设有单项轴承，且单项轴承的外圈上焊接有齿轮盘，所述驱动轴外侧的推车本体底部焊接有L型挤压筒，且L型挤压筒的另一端的内部滑动连接有活塞板，所述活塞板外侧的中间位置处焊接有卡条，所述L型挤压筒一侧的顶部连接有导向管，其中一根所述推车把手的底部横向焊接有挤压筒。本发明方便辅助推车进行上坡行走，降低劳动者的强度，使得推车本体在上坡时更加省力，下坡时便于对推车进行减速。
