The invention discloses a construction method of a concrete trestle and foundation pit connection joint structure. The construction method comprises the steps that firstly, a center area of a foundation pit is determined, and a trestle construction area is selected; secondly, a first supporting structure is constructed in the foundation pit; thirdly, a second supporting structure is constructed in the center area of the foundation pit, and then a horizontal platform is arranged above the second supporting structure; fourthly, a steel bar structure of a first slope ramp is constructed in the position, between the horizontal platform and the edge of the foundation pit, above the first supporting structure, then concrete is poured onto the steel bar structure to form the first slope ramp formed by the reinforced concrete, and antiskid strips are fixed on the upper surface of the first slope ramp; fifthly, a buffer platform parallel to the ground is arranged in the position, above the foundation pit, on the ground and connected with the first slope ramp; and sixthly, a second slope ramp is constructed between the buffer platform and the ground. The concrete trestle and foundation pit connection joint structure is firm in device and safe in driving, and the earthwork transportation efficiency is improved by 12%.
Description
technical field [0001] The invention belongs to the technical field of construction engineering, and relates to a joint structure for connecting a concrete trestle bridge and a foundation pit and a construction method thereof. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. During the excavation of foundation pits, especially in the construction process of super large and deep foundation pits, as the excavation area of foundation pits becomes larger and deeper, the difficulty of excavation construction becomes greater and greater. During the excavation of extra large and deep foundation pits, it is generally necessary to use the trestle system as the foundation pit support structure, and then use the trestle bridge to excavate the extra large foundation pits in partitions. The trestle is roughly divided into the trestle area, the trestle slope area and the t...
