The structural section 1 is made by building templates by casting. When setting up tenon 2 and mortise 3 on structure section 1, after putting up the template of accomplishing 1 main part of structure section, carry out the template of tenon 2 and mortise 3 and build to make tenon 2 and mortise 3 pour as an organic wholely with 1 main part of structure section, with the wholeness ability that improves structure section 1, improve tenon 2 and mortise 3's structural strength simultaneously.
Particularly, the tenon template is preferably a prefabricated template so as to reduce the construction processes and improve the construction efficiency. The prefabricated tenon template is prefabricated into a corresponding structure according to the structure and the shape of the tenon 2. During concrete construction, the tenon 2 is only needed to be used for prefabricating the preset position of the main body template of the template installation structure section 1, and then the integral pouring construction of the structure section 1 can be completed through pouring.
Specifically, when the template of tenon 2 is set up, construction can be carried out through the prefabricated tenon template, and similarly, the mortise 3 template can also be made in a prefabricated mode. Meanwhile, the structural shape of the mortise 3 is opposite to that of the tenon 2, so that pouring construction of the mortise 3 can be completely carried out by utilizing the tenon template, materials can be saved, and construction cost is reduced.
Specifically, when the tenon 2 is arranged, the bottom and two side templates of the tenon 2 are firstly installed in place, the template on the top surface of the tenon 2 is then installed in place when the top surface of the tenon 2 is poured, and then concrete is continuously poured until the pouring of the structure section 1 is finished.

Referring to fig. 3-6, specifically, the tenon 2 is a convex structure, the mortise 3 is a corresponding concave structure, and the convex structure and the concave structure are engaged with each other, so that the two adjacent structure sections 1 are clamped together. Further, after two adjacent structure sections 1 are combined together, the two structure sections 1 can form a whole, so that the independent settlement of one structure section 1 can be effectively prevented, the occurrence of slab staggering is prevented, and after the two structure sections 1 form a whole, the overall performance of the underground structure is improved, and the settlement of the underground structure can be effectively prevented.
Specifically, tenon 2 is the arch of a right angle triangle-shaped structure, the top surface of tenon 2 sets up along the horizontal direction, the facade of tenon 2 with the side wall 4 of structure section 1 is connected, the inclined plane of tenon 2 keeps preset length. The mortise 3 is a triangular groove opposite to the tenon 2.
Specifically, the tenon 2 is a protrusion with a right-angled triangle structure, and the tenon 2 includes a top surface 21, a vertical surface 22 and a slope 23, where the top surface 21 and the vertical surface 22 are two right-angled surfaces of the protrusion with the right-angled triangle structure, i.e., the top surface 21 and the vertical surface 22 are perpendicular to each other. The vertical surface 22 is connected with the side surface of the side wall 4 as a whole, and the top surface 21 is arranged along the horizontal direction, that is, the bottom surface is arranged perpendicular to the side surface of the side wall 4. The inclined plane 23 is the hypotenuse of the protrusion of the right triangle structure, and the inclined plane 23 is disposed between the top surface 21 and the vertical surface 22.
Specifically, the mortise 3 is a triangular groove arranged opposite to the tenon 2, and the arrangement mode of the mortise 3 is the same as that of the tenon 2, which is not described herein again.
Specifically, the length L of the slope 23 of the tenon 2 is determined according to the following equation:
wherein theta is an included angle between the inclined plane of the tenon and the side wall of the structure section, d is the length of the bottom surface of the tenon, n is the number of soil layer layers right above the structure section, and r isnThe gravity of the n-th layer of soil from the surface of the earthnIs the thickness of the i-th layer of soil from the earth's surface to the bottom, s is the upper top surface area of the structural section, t is the weight of the structural section, n0The number of tenons on each structural section.
It can be seen that, when setting up tenon 2, through the length of the inclined plane 23 of adjustment tenon 2, the bearing capacity of promotion tenon 2 that can be very big to prevent that tenon 2 from damaging the inefficacy, and then can promote the structural strength of tenon fourth of the twelve earthly branches structure.

Referring to fig. 2, the construction is divided into 5 sections in the construction, namely, a structural section a, a structural section b, a structural section c, a structural section d and a structural section e, when the structural section a is constructed, a waterstop is normally arranged at a construction joint, but a mortise and tenon structure is arranged at the construction joint of the structural section a and the structural section b, the section length of the tenon 2 of the mortise and tenon structure is 200mm, the height of the mortise and tenon structure is 400mm, and due to the existence of the construction joint waterstop, a distance of 200mm is reserved between two rows of the arranged tenons 2, so that the position of the waterstop is avoided (the size of the specific mortise and tenon structure can be enlarged or reduced according to the size of the structural dimension).
Specifically, in the mortise and tenon structure, the tenon 2 part is arranged on the part which is poured firstly, namely the structure section a, and the mortise 3 of the structure section b is directly poured and formed according to the tenon 2 of the structure section a. Specifically, set up tenon 2 on the side wall 4 of the structure section a of pouring earlier, the preferred prefabricated template of tenon template to reduce the construction degree of difficulty, mortise 3 sets up on the side wall 4 of the structure section b of pouring after and structure section a contact, and mortise 3 on the structure section b directly pours for the template according to tenon 2 on the structure section a, in order to improve the efficiency of construction, resources are saved.
Specifically, the number of the tenons 2 of the structure section a is 6, and the number of the tenons 2 can be adjusted according to actual conditions. When the tenon 2 is arranged, the structural sections a are distributed along the center of the side wall 4 symmetrically.
Specifically, in order to avoid the honeycomb pitted surface of the tenon 2 during construction, the bottom and two side edge templates of the tenon 2 are firstly installed in place, the top surface template of the tenon 2 is installed in place when the poured concrete surface rises to the top surface 21 of the tenon 2, and then concrete is continuously poured until the structure pouring is finished.
It can be understood that the construction joints are large in structure and need to be constructed step by step, the construction joints are formed between the parts which are firstly poured and the parts which are later poured, the designed protruding tenons 2 and the main structure are poured together at the construction joints of the structural sections 1 which are firstly constructed, the positions of the tenons 2 are only arranged on the structural side walls 4, the construction is convenient, the number of the tenons is preferably 4-6, the tenons are symmetrically distributed on two sides of a water stop belt of the construction joints, the later pouring structural sections 1 directly use the firstly poured sections as end templates, and the poured concrete and the tenons 2 are combined into a simple mortise and tenon structure; the size of the tenon 2 is suitable for the structural size of specific construction.
Meanwhile, the setting mode of the mortise 3 is the same as the pouring mode of the tenon 2, and the mortise and the tenon only need to be relatively set, which is not described herein.

And the mortise and tenon structure can not bring more difficulty to construction, and is simple to operate. It can be seen that the present invention has at least the following advantages:

Particularly, the mortise and tenon structure includes tenon 2 and mortise 3, and tenon 2 and mortise 3 set up respectively on the both sides edge that structural section 1 is located side wall 4 of construction joint department.
Specifically, in the above structure for controlling uneven settlement of the expansion joint of the structure, the length L of the slope 23 of the tenon 2 is determined according to the following formula:
wherein theta is an included angle between the inclined plane of the tenon and the side wall of the structure section, d is the length of the bottom surface of the tenon, n is the number of soil layer layers right above the structure section, and r isnThe gravity of the n-th layer of soil from the surface of the earthnIs the thickness of the i-th layer of soil from the earth's surface to the bottom, s is the structureThe upper top surface area of the segment, t is the weight of the structural segment, n0The number of tenons on each structural section.
